Arrived on time, as ordered, was easy to install & works perfectly with Windows 10 OS. Cost a little more than last ones but we'll worth it. Used to interface radio/computer. Recommend.
By: Joe H.  on 2019-11-06
Worked flawlessly as promised right out of the box. No issues associating the drivers. As distinct from other similar products, is completely transparent to Windows, whatever software (or terminal emulator) you're using and the hardware you're configuring. LED indicators are definitely value added.

This product works as advertised but I wish the Type C connector was more robust. The male metal element, that is inserted into a type C slot, is not well attached the the rest of the housing. It has always been a little bit loose but I needed the converter so I put it into service.
By: Dylan  on 2019-09-21
Excellent USB to Serial programming cable. Plug and play with Windows 10.Stay away from Prolific chipsets and pick an FTDI based cable like this one.Since this does not have the typical male screws to secure it to a DB9 female port (it has two female screw mounts / standoffs), I did have to forcibly remove the screw mounts / standoffs to actually use it with the device I needed to program (see pic).The indicator LEDs are a nice addition as well.

This USB-C to serial adaptor worked perfectly on my Mac OS Mojave. No drivers needed. Used the very basic but functional "screen" command from the terminal App and was able to console into various Cisco gear like a champ. Lights for the pins are nice feedback for the serial comms. Excellent tool.

Need to attach older peripherals to newer computers and works well.
By: W. Price  on 2019-06-17
Installed easily with Windows computer system. Requires a USB socket on the computer not an expansion USB socket device that adds more ports to a computer. Requires a direct plug-in.Also it seems to assume you will be plugging into another cord as it will not plug into a regular DB9 socket that expect the screws to be attached to the plug for holding it to the computer. Press fit only requires removal of the two hex mounting nuts.
By: Amazon Customer  on 2019-05-26
I Love it when USB Equipment actually works.I run 8 serial ports now for monitoring a communication program.

Great little unit for router work!
By: Ron Meidinger  on 2019-04-06
I plugged it in and it immediately started detecting for the drivers, and worked once the drivers were installed, I didn't even have to put in the CD. Installed as Com3 and works perfectly for me.

Purchased this RS232 adapter to use between a windows 10 computer, and a ham transmitter. No problems connecting to computer everything worked flawlessly once parameters were setup in software unit keyed transmitter via a opto coupler without issue, except one minor problem RFI. The RFI was minor but was there so that's why I can't give it a 5 star rating.

I bought a Yaesu FT-450AT from a local ham and he gave me a serial2usb adapter and it did not work. After a bit of googling and reading I was linked to this from a website. I was told there is would work and based on that I ordered it. When it arrived and I got it hooked up to the radio and pc after a few seconds it started to let the radio talk to the computer and vice versa. Very much recommend this if you are trying to connect a amateur radio to your pc. I found some of the others available just won't let the radio and pc communicate.
By: Ryan  on 2019-03-19
I use this device everyday with my Panasonic toughbook 54. I have NOT ran into any issues with this product and have been using it for over a year.
By: Phil C.  on 2019-03-15
I have had at least 4 different USB to serial adapters over the years. The connections would drop and wait for something to move, then find out you had to reset the adapter. This Gearmo adapter has worked flawlessly since purchase and has yet to drop a single connection. I count on this for equipment configuration for work and am so impressed, I just ordered a Gearmo USB to dual serial adapter. Highly recommend this adapter.
By: Moefugger  on 2019-03-07

I have used this with Linux laptops and desktops for a variety of instances where I needed a temporary serial connection to work on some hardware. The status lights on the case are icing on the cake, reminding me of the serial break-out boxes we used way back in the olden days.

works great, better than some expensive units I've been using for years. I use this for industrial controls, such as PLC's and HMI's
By: W. Wong  on 2016-04-22
This is a great USB to serial. It works great. The only drawback is that it has the hex screw which needed to be remove in order to work. This product need to be redesign with the thumb screws and it would get a 5 stars from me.

By: CraigC  on 2016-04-12
After you install drivers (for Win 7 64 bit) from the CD, it works great. I have 3 other devices called Serial Gears to convert a USB to a COM port for serial devices, this one works just as good, very handy.
By: Tyler Pomerhn  on 2016-04-05
Works on my laptop with Windows 10, perfectly. Other dongles with the Prolific chipsets (2303 or otherwise) all were extremely problematic and would either fail to register as a COM port or would potentially crash the computer, altogether. This isn't just a "Windows issue" because I have other co-workers who need COM ports and own Macs, and the Prolific was a pain with them as well. This adapter, however, worked out of the box with no additional drivers and I have yet to have any issues with it.

Works just fine with windows 7, 8 and 10. Also the lights help with troubleshooting because its easy to tell if the serial connection is passing data, even when you have the settings (baud, data bits, etc) wrong.

By: John Moore  on 2016-02-19
As a Network Engineer working with Cisco products it is necessary for me to have a serial port available to console into routers and switches and new notebooks no longer have a serial port as a standard feature so USB serial adapters are required. If you just have a cable then if the console port does not come up then you have to figure out if it is the notebook or the console port that is causing the issue. Having the LED breakout indicators makes this much easier. I highly recommend this product.

Works great for many uses. Authentic FTDI based chipset, so it works without a fight on both OSX, Windows and Linux. We use it with many different switches and network gear.
By: C Miller  on 2016-01-28
Bought this one to replace a Prolific adapter that does not work well, used for several hours without issue
By: Prag  on 2016-01-27
The combination of the FTDI controller which is solid and ubiquitous (you likely already have the driver loaded) and the status LEDs for each signal line make this a great debugging tool. The blue power LED is a bit too bright (aren't they always) but it does make it easy to tell if the device is connected. The materials aren't fancy but feel solid and the cable is seems rugged enough. This one costs a bit more but if you think you might want to see what's going on with your serial comms then this one is worth it.
By: Jason S.  on 2016-01-25
We use this as an alternative to buying the Rockwell RS232 to usb adapter that costs $170. I personally have used it on a Micrologix and PLC 5.

Finally a Serial to USB adapter that works flawlessly with Windows 10. I was trying to use an old Gigaware adapter and even with drivers that would load in Windows 10, it would still crash my machine. This has been working flawlessly so far and I am confident it solved my issue.

Works great, and its easy to tell which end has a problem when you cant connect.
By: John Berry  on 2015-12-19
This is a must-have for all PC techs and field work for troubleshooting sensors and RS232 devices. This has the legtimate chipset with real drivers that aren't blocked by MS. I love the status lights (that have proved reversed wiring before for me) and the ease of installation. I've had others and this is the one I kept. Use it with Putty (a free form of Hyperterm) and you'll be happy with your terminal screen every time.
By: Jim O'Brien  on 2015-12-18
I bought these because today's computers normally do not come with a serial port any more. I built and programmed a time and attendance system for work, and these worked perfectly.

Purchased this to attach the Singer Professional Sew-Ware v2 embroidery card reader/writer to my Windows 7 computer. Although I was able to install it (using the device manager to search for the drivers on the CD), the embroidery software was not able to find its device. Therefore, I am returning the adapter and purchasing another brand that a reviewer says works with the PSW software and hardware.
By: Justin Dover  on 2015-12-02
The cable length is great and it works very will with my MacBook Pro. I used it mainly with the "Serial" app, which I found to be a great match for serial terminal work.

This is about the BEST USB Serial Adaptor I've used so far. Working in the telecom industry we've had a number of these units over the years as most laptops no longer have a serial port on them.
The biggest benefit is being able to see the datasets on the physical side. Visually identifying transmit and receive can save a tremendous amount of guess work on determining which direction to look when isolating problems. Is it the device, laptop or the adaptor?
With visual indicators confirming the physical connections is priceless.

Works great, no issues with Windows 10. I'm happy. One nit I will pick though is that the sticker with the LED indicator labels was installed in a somewhat misaligned position so if you're looking at the device form the wrong angle you could mistakenly believe that the wrong indicators are illuminated... I started peeling up the label to shift it back over to where it's supposed to be but the adhesive wouldn't have been good for a 2nd application so it's staying where it is.
By: Harold M. Ballard  on 2015-09-12

Works great the first time, unlike other adapters I've tried. Installed very easily. The key is in the FTDI Chipset. I will never use an adapter with a Prolific chipset again nor would I recommend them. I use this to access Dell network switches using Putty and it works great.

I tried installing Windows 10 and my prior Prolific usb to serial adapter did not work with Windows 10. I actually often had trouble with it working in Windows 7 after each update too as the drivers were constantly prone to errors. Apparently the makers of those devices have abandoned them. As far as this GearMo USB RS-232 Serial Adapter goes, I can confirm that it is plug and play with Windows 10. I first installed it on Windows 7 prior to the upgrade (simply plugged the usb in and Windows found the proper drivers). I then went into device manager and changed the com port and baud rate in device manager to the proper com port and baud rate. I then did the Windows 10 upgrade. After the Windows 10 upgrade I just needed to go back into device manager and update the driver. Boom, works now perfectly. I can only assume that it would also be plug and play with Windows 10 if you simply plug it in and Windows will find the drivers. But anyway, I am using this now on Windows 10. I am a very happy camper. I had years of frustration with the Prolific usb driver and am so happy to be with GearMo FTDI chip technology. Thank you so much GearMo!!!!!

Works fine...But it has to have male pins! Carefully took it apart, removed the female pins.
Even though it can't be mechanically screwed in, it holds pretty good.
Used it on a PCR1000 radio. No problems with communication to radio.

By: Gary Miles  on 2015-06-15
Worked as expected. Indicator lights are really helpful to know things are working. Easy to load driver from CD. I used it with Windows XP. One minor thing is the threaded fittings sticking out so it may not pull up tight directly to some panel connectors. I just used an adapter cable and it was fine.
By: GAusten  on 2015-06-11
I purchased this cable adapter in Nov 2014 and started using it in Jan 2015. While it took a bit to get the drivers loaded onto my tablet, once I managed it, the cable worked fine. At least until July 2015 when it went completely dead. Fortunately, I had purchased another cable from a different vendor (Valley Enterprises USB to RS232 Serial DB9 Cable Adapter FTDI Chipset) so could continue working. We'll see if this cable will last more than a measly 6 months!
As a side note. I had to download FTDI drivers from online to make these cables work with some of my equipment, but for other it worked fine with the supplied drivers. http://www.ftdichip.com/FTDrivers.htm
By: Burns  on 2015-06-10
Worked perfect right out of the box. We tried many other USB to RS232 adapters, but this was the only one to properly load all the drivers and work on Windows XP, Win 7, and Windows 8.1 machines.

By: Xero  on 2015-05-24
love it, using it with a rs-232 to rs-485 adapter, and that is actually working better than a dedicated usb->rs485 adapter I tried. Also love the lights on this thing, you can really see if something is happening or not, which, for my application, and coming from an adapter that didn't work at all for me, was a nice improvement to know it's actually doing something.

By: Dinsy  on 2015-05-07
I'm actually amazed this adapter worked. I've tried so many, mostly with Windows 7. But I took a gamble on this one to try it with Windows 8.1 and was not disappointed. I used this with some old devices, one homemade, and they all worked. Thank you GearMo for making something that actually works!
Update: Tried this adapter with windows 10 and an ActiveHome CM11A X10 interface and all works well. The FTDI driver installed automatically for Windows 10.
By: VideoWizard  on 2015-05-02
Great product. Works as advertised. Status LED's are a big help. I will probably buy another at this great price.
By: C. Bollig  on 2015-04-25
The traffic lights are a nice touch since I work on some old flaky equipment that locks up when you are programming it. Tried two others before this one and yea the FTDI chip is the only major difference. This one has the FTDI and it worked where others would not.
Blue plastic is medium grade and feels like it will break with rough use. I work in the field and it will be used roughly.
Even though the plastic is not the most durable and feels like it will break I give it five stars because for the price it is not an issue to have a spare or two on hand.

Highly reliable! I use it to communicate between Win7(64bit) PC and CNC machine (error-less communication is critical for me). I use different speeds and both software/hardware handshake - never had even one communication error! Great product! (Genuine FTDI)
By: Flyguy  on 2015-03-24
Ordered this to interface my amateur radio to my computer. Initially I have tried to use other brands of interfaces to hook up the RS-232 interface on my radio to my computer and always seemed to have some glitches. Since most if not all computers have now decided to remove the serial interface from their systems, it has become more difficult to interface some of the radios that still rely on the RS-232 interface. This unit fills the bill. I plugged it in to my windows 7 system and it immediately started loading the necessary drivers. I was hooked up and communicating in just a few minutes. It also has handshake indicator lights in case a problem arises. All in all a first class unit that does the job quickly and effectively.

By: James C  on 2015-03-08
This serial/usb adapter came with a driver disc and has worked well right out of the package. I am using windows 7. I don't have to plug in and reboot for this adapter to be recognized. Just plug it in and go. The driver allows you to select the com port I want as well as many other settings. Much better than the last one I had. I would buy it again and recommend for anyone with serial data needs with only a usb port on a laptop or other computer to use. Finally, a serial adapter that really works!

By: Doug Jones  on 2015-01-19
This is a high-quality and highly functioning adapter. That being said, the included drivers were ridiculous (Win 98, Win CE, 2000, XP, and that's it... what, no Windows Bob?) but they worked with Windows 7 just fine anyhoo. After 3 failed attempts with other "reputable name" USB-to-RS232 adapters, I'm finally able to get my MicroLogix 1000 PLCs talking to my laptops. The key was to eliminate the Prolific brand chipset from the equation and bring on the high quality FTDI chipset this adapter sports. The serial line signal activity LEDs are a plus.
I highly recommend this adapter!
By: Patrick  on 2015-01-16
Product worked as indicated. drivers work with windows 7 and the install was smooth. I am an IT professional and use this item at least once a week. If it wears out from use at some point I will buy another one just like it!

Shows up without a driver install under Windows 7 and Windows 98 SE under VMWare. Beautiful.
The length of the USB cable makes it easy to plug straight into whatever machine you're hooking up to, but because it has the thumbscrew sockets on it, and whatever you're plugging into will as well, it's impossible to use without an extension cable. I opened mine up and removed the sockets. It's uglier now, but more useful for me.

I needed this to connect to a RS-232 connection on a Lennox L-Series RTU controller. My laptop doesn't have a 9-pin serial just USB and this worked flawlessly. No awkward driver installation. It was compatible with built in drivers in Windows 7 and I was off to the races in a matter of seconds.

This adapter has the suggested chip-set for converting. This piece has worked great from day-one with zero issues at all! I have recommended this piece to the company I work for and we are now purchasing them for all our technicians.

one of the few converters I got to work with my device!

Works great with windows 7. Owned for two years and have had zero issues with this device.
By: Lorene  on 2014-12-13
I've used this RS-232 Serial converter for connecting to Cisco networking devices and various other networking equipment that utilizes a console port. This device was able to connect to all of them flawlessly. It was able to auto-detect the baud rate to apply for the connection and whether or not flow control was needed, which was reflected on the LEDs for each device connection. I also used this cable to xmodem a IOS file to an old Cisco Catalyst 2960 switch. This is a genuine FTDI chipset used in this device, http://hackaday.com/2014/10/22/watch-that-windows-update-ftdi-drivers-are-killing-fake-chips/ this link listed the drivers that affect fake FTDI chips. I updated my adapter to use the latest version that would "brick" the device and it is still detected and functions perfectly. I also made use of this adapter in linux using putty and cutecom and it detects perfectly as well, no need to modprobe usbserial vendor=0x???? product=0x???? it is plug and play.

Works as advertised. Lights are kinda cool
By: Jack of all Trades, Master of None  on 2014-12-01
I was a little skeptical at first, but after using it that quickly faded away. very easy to install and the extra LED lights to show the connection speed and lots of other things makes it well worth the price. I have several otherbrands of the same thing, are using to connect my telescope to my laptops. I've had problems with other versions this one was a dream. I highly recommended.
By: Azrael  on 2014-11-23
I've been running this thing continuasly for about a month interfacing my weather station to a computer and have had flawless operation. The Prolific version constantly crashed on Win7 home and pro. As a former IT Manager I thought that I could make the old one work, but the problem was the driver and no version I could find would fix it in Windows. I've used it with Linux, but this unit was the only thing I've found that works well with Windows.
By: Tim the tool man  on 2014-11-22
Works like a charm. Lets me connect my PC to industrial equipment which have only RS-232 9 pin ports. The female nuts installed on the connector require that you connect it to another cable, not directly to a D-sub port. LEDs could come in handy for troubleshooting communication problems. Windows 7 automatically installed drivers without need for the included disk.
By: B Miller  on 2014-11-22
This adapter works when many others fail. Well done!
By: paul rother  on 2014-11-20
I bought one of the cheaper USB/RS232 converters and had a lot of problems. It worked, but the drivers sucked up so much CPU, that the whole machine ran soooooo sloooow, thus rendering the application useless, as serial data was lost. With this guy (using the FTDI Chip) everything worked right off. I didn't need the LEDs, but i've been in plenty of RS232 situations where the LEDs would of been super useful. I'm on a mac using parallels, running XP for the application i'm using. Since i already had the FTDI driver installed, there was no setup, and this worked perfectly first time. I'll thru the other one i had in the circular file, what a waste of time that was.
By: Joshua Cardin  on 2014-11-16
Great interface convertor. No problems setting it up.
By: Brian  on 2014-11-12
This was totally plug and play on my windows 7 box. I've had a number of these types of things in the past, and there have always been driver issues, etc.
I use these to access the serial consoles on various servers. I had been skeptical about the usefulness of the LED indicators, but have found that they are quite useful -- if the lights are blinking, then you have some data being sent, even if the baud or other settings are wrong. This helps troubleshoot if my lack of console is a cabling issue, or a configuration issue, etc.
By: Mark G Matlock  on 2014-11-01
If you are looking for a USB to RS-232 adapter with some extra diagnostic capabilities, then this is an excellent choice. I have been using it to connect my iMac to a PDP-11/83 and the LEDs on the RS-232 side have been very helpful. The USB side works perfectly with OSX or Ubuntu running under VMware on the iMac as well. Great Product!

It just works perfectly with every serial device I throw at it. If you need a serial port to program a network device or an old server that is managed via serial port this is what you want. Hasn't failed me yet in about half a year. Its actually more troublesome sometimes to find terminal software to use this on some operating system since they do not include them in the operating system anymore fortunately in windows there are tons of free options out there inluding hypterterm which can still be downloaded if you need it.
By: WangoTango  on 2014-10-19
I got it for all the LEDs on it. I support some old devices that still use RS-232 to talk to a PC and it is nice to see the status of ALL the lines. I love it, and I haven't had the unit lock up from minor ESD events like some other units I have used in the past.
By: M. L. McKenzie  on 2014-10-18
Finally found one that works as advertised for D-Rats and RMS Express.
By: Patrick McLeod  on 2014-10-14
Purchased the USB to RS232 to replace an older unit. Tested on Windows XP and Win-7. No issues with this product and
the unit worked perfect.
By: S. Fitzgerald  on 2014-10-10
This is a sweet little USB-RS232 adapter. My old one caused my Windows 7 PC to BSOD at speeds over 38400, but this chipset does not. It also works on my Mac Book Pro. The LED indicators are WONDERFUL!!!! They make troubleshooting connections so much easier. Even programs such as CoolTerm, which show indications on the console window aren't as useful as the indications on the adapter itself. GearMo's website has all the latest drivers for Windows and Mac, which makes installation a breeze.
If you're looking for a USB-RS232 adapter, look no further than this one.
By: Robert Kondner  on 2014-10-10
I probably should give 5 stars but they have the LEDs on the wrong side. I have used a number of such adapters but these work flawlessly. I use a COM port driver in my code, ancient piece of code, and it functions 100% with this adapter. The FDTI chip set in this device seems better supported, it is nuts to use anything else.
By: Julio B. Donastorg  on 2014-09-29
This thing is awsome, looks and feels robust so im not worried about it being broken on my backpack.
By: SEAN BALES  on 2014-09-28
These work great. If you work in IT and routinely plug into serial ports to manage network devices or other devices, this is a great tool. It's handy to see the status lights to know if the pin-out on the device is correct. The usb cable is also a nice length. I've personally tested this on Linux and Windows 7. Both required no manual installation.
By: John Dorobish  on 2014-09-25
This adapter does work with Microsoft 8.1 and worked perfectly with the machine I had connected to the computer.

Works great for old serial port adapters for the Phillips TSU1000 and TSU2000 remotes. I have been using these remotes and programming and organizing buttons on the screen using prontoedit 4 since late 1999. Needless to say, it is hard to find adapters that make the serial port adapter work for these remotes. I came across GearMo and ordered one and not only did it work, it automatically installed without the mini CD. Because of the age of the remotes, you also need to set the port to com1 on windows 64 bit PCs to make it work. If you do this, it takes but a few minutes and you are up and running. I can finally retire my old windows 7 32 bit pc which was hanging around just to edit my remotes. I am ordering a second one now. I highly recommend this device for serial to USB applications.
By: Dan Baldwin  on 2014-09-04
Works perfect for my application. Running windows 7 that found it right away. C++ also liked it. Worked to my advantage to see the rx and tx lights blinking. Great product , will probably buy more soon.

Did not work for serial Wacom tablet.
By: gymratt  on 2014-08-16
I have to constantly access serial ports on enterprise computer equipment and the absence of serial ports on laptops was something I had to overcome. This cable not only solves my connectivity problem but also comes with a very handy traffic light to let me know if the ports are even working as soon as I plug the cable in. Gear-Mo updates their drivers so I advise anyone buying this cable to visit their website for the latest driver. As far as configuring it simply follow the documentation for your OS and you'll be on your way.
I have used other USB to serial cables but if you need serial DB-9 connectivity buy this one, and you'll be glad you did.
By: Kindle Customer  on 2014-08-12
arrived as promised and works perfectly.

Great tool if you do a lot of RS232 work
By: A.C. Mendiones  on 2014-08-04
If you're still using serial devices and have moved to Windows 8, you need this adapter. If you had adapters based on the Prolific chipset, the available drivers for Windows 8 (as of 8/2014) don't work. This adapter uses the newer and better supported FTDI chipset. Their drivers work. This adapter works.
By: Siggi Bjarnason  on 2014-08-01
Only done limited test on this so far but it seems to be a rock solid product. I especially love all the LED's that tell me exactly what is going on at the RS232 layer. BTW the installation on my Win8 64 bit laptop was flawless and fast, didn't even need the included CD for drivers.
By: Robert S. Boisvert  on 2014-07-29
First Visual Observations:
The USB to serial adapter was small but attractive in its construction with visible labels on the corresponding LED’s. The serial port enclosure was a translucent blue.
Received the package intact, no damage was found.
The USBG-FTDI-LED was real simple to use, plug & play installed what I needed right away on my Windows laptop. I had used this serial adapter on older modem that operated through a serial port. Although going back to 56k was a pain the data transmission from the modem connection to the laptop was on the ball and the LED’s worked appropriately. This was a life saver despite the Internet connection time with 56k.
The cable adapter is long enough that it stayed where I wanted it when getting the modem set up from the laptop. The LED’s were clear and easily distinguishable do to the darker label. It is portable, coiling up the cable is no big deal and doesn't take up mu room in the bag.
No cons, this is a great little device.
Having trouble with my onboard modem, this was a life saver when having to break out the old separate modem unit to cover my Internet. The USBG-FTDI-LED Serial Adapter was inexpensive which was even better.
Special Note: This review has not been solicited by the seller of this item.

Worked great on my Windows 8.1
By: EngineerGuy  on 2014-07-16
Yes, this uses the FTDI chip and it works. A Prolific-based unit did not work in the same application. The pretty lights are fun to watch when in operation, but you probably won't need them. As an engineer, like to watch things work so the extra couple of bucks was worth it in case I had to do any troubleshooting. But then you need to have trouble in order to troubleshoot. I didn't have any.
About as "plug and play" as you can get.
By: Larry Comden  on 2014-07-12
I wanted to use this in an amateur radio application.
It performed flawlessly (I have had trouble with other similar devices because of RF energy).
By: PTW-105  on 2014-07-11
I broke this product review up into 5 pieces: design, build, functionality, misc, and summary. There's a TL;DR at the bottom for those who are interested.
I always prefer to have more information over less, so the status lights are good, but I would prefer that there were different colors. All indicator lights are all amber which kinda bleeds between indicator windows. It's really not that bad though, but I think different colors would help resolve the issue. The TX/RX lights are a tad dim on mine, unknown if this is a standard problem or if I got a few poorly made LED's in the mix. The blue glow from the RS-232 end is pleasant and a nice indicator to know that the board is receiving power from the USB connection.
Quality wise, this product is okay. The plastic exterior covering for the RS-232 side is a bit cheap feeling and I'm concerned that it may not hold up well in the relatively hostile environment that a data center or server room often is. The black area where the indicator lights are visible feels like it's just a clear plastic sheet, so someone who has huge burly thumbs and no sense of his/her own strength may accidentally punch that film inward.
I tested this device with a Cisco 1841 and 2811 and it worked flawlessly just as expected. The additional driver CD was not needed as my Windows 7 PC picked it right up and assigned it COM6, and away I could PuTTY. The TX/RX lights blink when sending commands and receiving feedback from the routers, so they seem to function as expected. As mentioned above, the only functional change that would have been nice is to have different color lights.
Not really a product flaw, but the product description could use a tad bit of work though. It's not misleading, but it's a bit lacking. I had to go to the Questions/Answers section to find out the length, which is long enough for my uses. It also would have been nice to know the LED colors before purchasing. I like the cable material, the outer cable jacket is clear and is nice and flexible.
Overall the product is great and I would recommend it to others who have a need for RS-232 connections, don't have serial ports on their modern computers, and are into things that both light up and blink.
By: Steve65  on 2014-07-11
Don't waste your money on anything with a prolific chipset - they don'tvwork with windows 7 or 8. This unit just plain works! As a net admin I need my serial port to work consistently and so far, this one has been flawless!
By: fisherman  on 2014-07-01
Purchased this serial adapter for use with my Surface Pro2 to mainly use Putty application to configure Cisco gear. It works perfectly for that purpose, I also like that it has status lights and the cord is a good length and not short like some other brands that I have had in the past.
By: Robert N. Trout  on 2014-06-07
Works perfectly AND with Windows 8 which many other adapters do not. One other adapter on the market will work also but it costs twice as much.
By: David C. Miller  on 2014-05-28
Bought it for a samsung laptop with Windows 7. Was able to configure with no issues to connect to Cisco devices. Likes to come up as COM3, but that is more an annoyance rather than a functional problem. Unit is not too bluky with the blue housing. Did have to load the drivers to get the unit to function correctly
By: kurtgo  on 2014-05-26
Spent the extra money for flashing lights, however the lights are upside down. All of the computers I have owned have serial ports that have the short side of the DB-9 connector down. When I plug it in, the lights are facing down, and useless. I should have bought the cheaper one, but this thing functions fine and is recognized automatically by Linux. Can't complain about functionality.
Just look closely at the product photo, then pick any device with a serial port (like rasberry pi) and you will see what I mean.
I would give it five stars if the lights were on the top.
By: R. Brown  on 2014-05-18
I used this cable with a Raspberry Pi to connect with an 8-bit Atari SIO cable. I did not need the VPC drivers from the FTDI site. Works great!
By: Ronny G  on 2014-05-15
Wow! What a great product with visible indicators AND a cable to the USB connector, allowing me to move it away from the laptop. Never any question whether the connection is good. It works very well with both Windows 7 and Windows 8 machines, and the price is outstanding!
By: Lori Broadway  on 2014-05-06
This was the reason for my initial purchase, so I was very happy with this item, If I could have just purchased this item alone with free shipping, I would have been very please.
By: VIPbeachBum  on 2014-05-01
Works flawlessly compared to the Belkin adapter I replaced it with. Works we'll on all my old serial port stuff I own.
By: Nick K.  on 2014-04-26
Works great, links up just fine with my radio scanner for programming. The PL-2303 adapter I tried previously didn't work at all.
By: Bryan J. Schaefer  on 2014-04-11
I have a few computers. My two main used computers, both Windows 8, have different experiences. My laptop registers this as a microsoft mouse. The other registers it correctly, but this is frustrating as I bought it to use mostly with the laptop. Looks like I'll have to get a different one. At least I have this for my main PC.
By: Amanda Feldgreber  on 2014-03-31
Works great without having to search the internet for drivers that only work every other time you turn the computer on and must be constantly reinstalled. I had to have one that works this great to run outdated hardware for work with out it I would be sunk.
By: John La Costa  on 2014-03-29
Worked just great with the the Dell laptop running Windows 8.1. Would recommend to anyone who needs an adapter to RS-232
By: Amazon Customer  on 2014-03-22
Plug and Play! Most cheap ones do not work. This worked great with my LP-100A Wattmeter for Ham Radio. You will need a 9 pin straight through serial cable with this idem because it has the nuts on both the meeter and the adapter. Think of it as a internal card connection. It was fast delivery thanks!
By: escortwagon313  on 2014-03-08
No issues using this with a Win 7 64bit machine, it works great and gets the job done. The lights are nice to see that its actually doing something, especially if I need to do some troubleshooting with what its connected to.
By: Brett B  on 2014-01-24
I needed a serial cable to communicate to an Allen Bradley Micrologix PLC and my laptop does not have a RS-232 serial port. I read about some bad experiences people have had with other adapters. It seemed that the general consensus has been to stick with the FTDI chipset adapters.
After looking through some products and reviews, I came across this item. In my opinion, the LED lights to indicate activity was good feature to have for any troubleshooting.
My computer uses the 64-bit version of Windows 7. When I plugged the adapter in, the OS recognized it and downloaded the drivers via Windows update. It defaulted to COM7, so I changed it to COM1 and connected it to the PLC. I auto-configured a DF1 channel in RSLinx Classic and immediately discovered it using RSWho.
I've had it connected to the PLC all day and there have been no issues in the communication. I checked the diagnostics for the channel and there were no bad packets, timeouts, or retries.
This seems like a great product.
By: Robert L. Doerr  on 2014-01-22
I have always had the best results when using USB to serial adapters that are based on the FTDI chipset. This particular adapter uses the FTDI chipset and also has status LED's to show the activity on the lines which can help troubleshoot serial issues.
I would highly recommend this adapter.
By: Myself  on 2014-01-08
After having struggled with corrupt data on my PL2303-based adapter every few minutes, I was suspecting problems with the target device, especially when the problem persisted after swapping adapters, reloading drivers, and trying a different PC.
Lesson learned: Replacing a Prolific chip with another Prolific chip isn't gonna fix it! Go FTDI or go home.
I bought (two of) these and the problems haven't come back; I can receive *megs* of text without so much as a hiccup. Logging over a long weekend used to be completely out of the question, now it's become routine.
And yes, the diagnostic LEDs are every bit as useful as you'd imagine, perhaps more so. Not only do they show you TX/RX and flow control, but they show you *when the port is open at all*, which is super handy if you've got multiple adapters plugged in and you've lost track of which COM port is which. Forget the paperclip loopback! Forget unplugging things to see which port stops responding! Just watch each adapter go all Christmas-tree when you open its respective port, and the mystery is conclusively solved.
My colleague has been using the other one to drive an old board plotter, which had exhibited inexplicable, random, and extremely frustrating bugs for months. Switching to a genuine FTDI adapter made everything suddenly work! The misbehavior is gone, the software doesn't lock up anymore, and we're back to making boards in-house instead of sending them out. Turns out the plotter wasn't bad after all, it was just a cheap serial adapter!
I'm never skimping on cheap serial adapters again.
By: J. Meran  on 2013-11-30
Works great with Win 8.1 64 bit. Didn't use supplied driver disk. it just worked! My application is a simple "Dumb" terminal program running a piece of test equipment. The LED's are great and will really help if problems arise.
By: Glenn  on 2013-11-26
Works as described and the lights are a plus for trouble shooting. Win 7 found and installed with no problems. I use it for TX Using Ham Radio Software.

I purchased this cable to interface with a DOS based system. I had another brand of cable that I could not get to work. When I received this cable I plugged it into my Windows 7 PC, Windows installed the drivers that I needed, and that was it... Completely plug and play..
By: Sitesby  on 2013-10-30
I purchased this to connect to Cisco consoles. I have had no issues using the serial adapter with Windows 8 or MAC OSX.
By: Gadget-Guy  on 2013-10-28
Laptops, Desktops, Tablets.... all would cheerfully like scrape off the RS-232 interface from their shoe.
(along with the parallel interface, and the RGB video interface)
It's an interface that - just - won't - die.... along with all the zombie hardware that is still - inconveniently, operational.
On top of that, add 3 or 4 more versions of a psychotic OS's growing ever larger, slower, and less stable...
One must ask one's self "Is one giant leap backward for mankind" really worth it?
Still, if it's cheap enough, ?maybe? it's worth a shot.
Not all USB-RS232 are created equal.
They are OS type/version dependent.
They can be quite particular in their handshake with any given piece of ancient equipment.
On occasion, they will work.
Don't expect much technical support from outer Mongolia when it doesn't.
Just because it works on one device, it may not on others.
Change host device, OS (or, even a service pak) - and, it's instant drawer clutter.
Most will test operational with a RS-232 tester. (which may not mean much for your application).
By: Mwolf  on 2013-10-15
I needed this for connecting my laptop (which does not have a serial port) to a piece of lab equipment. My windows 7 machine did not need the included drivers (on a mini-disk), it just worked when I plugged it in. I am using LABView to communicate thru the USB adapter to control what the lab equipment settings are, or to communicate status/measurements from the equipment and this works beautifully. The LED's are a nice touch to verify that data is being sent back and forth, which helps when you are setting up for the first time and want to verify communications are working properly.
I haven't beat this up, but it is being used in a work environment and so far this has held up nicely. It's not industrial strength, but it also doesn't feel like it's going to break into pieces if I drop it. I bought several for our lab.
By: Bonkers Bill  on 2013-10-13
With most RS-232 test jigs you see one color for positive, another for negative, and no light for no signal. The lights on this adapter are only on when the signal is "active" - you don't get any indication if the signal is driven from the other side. So it works, so I still need to carry an RS-232 tester with full lights when I want to diagnose a balky connection
By: jhb204  on 2013-10-05
Works correctly and installs easily. If you don't need the lights, then go for a Sabrent unit. It uses the same FTDI chipset but $5 less.
Do yourself a favor and stay away from the Prolific PL2303 adapters. I've yet to get one to work correctly with Wndows Vista, 7, or 8.
By: Werner Kuballa  on 2013-10-02
I had to use this adapter to connect a laptop (running Debian Wheezy) to a Dell EqualLogic. Worked without a problem.
By: Jim Jewell  on 2013-09-05
works with Win8. this is for the professional that needs to talk RS 232. just about any USB/232 device will do. but to have the LEDs showing you whether you have communication, or not??? priceless.
By: Thomas Foster  on 2013-08-31
I got them fast, well packaged.
They work perfectly, first time / every time.
I bought four more.
Ditto for them as well
By: Aaron Possien  on 2013-05-30
I use it while programming where serial devices are used. The LEDs indicate all the states of data and transfer. The LEDs also let you know if your device is ready and when data is being transferred. For the price you can't beat it.
By: Amazon Customer  on 2013-03-15
I ordered this adapter for two uses: First to use with my old X10 controller at home and second to connect to the console serial port on a piece of test equipment at work.
For the X10 controller, I elected to the USB/Serial adapter on a Windows 8 PC. I created a "restore point" before inserting the mini CD that came with the adapter (just in case!). Then I plugged the adapter into a USB port and surprisingly there was no request to install a driver. So I looked at the Device manager and found that "USB Serial Converter" appeared without having to install the driver from the CD.
I then ran the X10 control software and it found COM4 and worked right away.
I haven't tried the test equipment at work yet, but I don't expect any problems. And the LEDs will be very useful for this.
Very happy with the product and the price.
By: Mark Newsome  on 2013-02-15
The old Belkin adapter I was using seemed to cause the dreaded BSOD on XP and didn't support Windows 7. This one works great on either OS. With this adapter I can use my Computrainer with a (late 2008) Macbook, running Windows 7 under Parallels. The blinking LEDs are a nice touch -- they let you know it's working!
