Robust USB-to-Serial Adapter

By: E. J. Beyer on 06/27/2019

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.

Really good USB->Serial product

By: petechic on 05/20/2016

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.
