Use to communicate with fire panel

Review by Steve

I needed this to help program and diagnose a fire alarm panel. I initially wired my connector incorrectly and could not get any communication. Thanks to the lights on this adapter I was able to quickly diagnose my mistake and get my programming done. I had originally used a more expensive adapter from a local store but couldn't get any communication and thought it was defective (which I later learned was my mistake). If you need a USB to serial, this is the only way to go!

Works, but

Review by Paul Mills

Would be nice if LED's were two color and showed true state of each line. Don't buy it for line monitoring capabilities.

It works fine

Review by Vandy Starkweather

Easy to setup and use.

This is the one to get

Review by PumpkinSeed

Don't mess around with other chipsets that can be unstable, have poor driver support and even may cause Blue Screen of Death when connecting and disconnecting. This has the very reliable FTDI chipset with status indicator lights at a great price. Cheers! ~Andrew

Review by Kerrick

I have needed this for a while now. I ordered and received easy to use and worked perfect. makes life easier programming 2-way radios.

Quality

Very helpful when resolving RS232-USB problems

Review by Arno

Too bad they put on the sticker slightly shifted so the indicators were not clear to see. Re-sticking it is a bit of a pain. For the rest a very handy and good working device.

Quality

Okay. Usable - though not perfect

Review by Big John

It didn’t work for my project but I suppose I can use this cable. I will keep it. I like the data light feature, that’s the best thing about it.In terms of quality— It’s too expensive for the cheap looking design and feel.

Quality

Worked great on multiple devices so far.
