Robust USB-to-Serial Adapter

By: E. J. Beyer  on 2019-06-27

I have used these adapters for over eight years in industrial and laboratory automation applications. They are the most robust and reliable USB-to-Serial adapter I have used. I operate these devices in hostile electrical environments with frequent and energetic transient events. I would advise you against using USB in similar environments, but if you have to, these adapters are up to the challenge.I mostly use the RS232 mode, but I have used the RS485 2-wire mode successfully. I had to open the case and adjust the option jumpers to make it work, but the unit was capable. This could be a pain if you have to swap the unit between communication buses frequently.I had a coworker fry one once. They had it connected to a device while injecting 10KV ESD pulses into the device, so maybe get the optically isolated variation if you are working near 10KV pulses.

Easy to set up and worked immediately. After weeks of working with different serial devices, installing the Serial Gear Adapter solved all our problems in minutes.

Really good USB->Serial product

By: petechic  on 2016-05-20

I've used this products for years. It's really good. It was tough to get through the drivers, a bit, but I ended up figuring it out. Totally good with screw terminals, in the field.
