Review: True plug-and-play - Worked first time. Easy to use. It became COM4 on Windows 11 without requiring any driver installation.
Review: Useful adaptor - This USB to 422 / 485 adaptor was easy to set-up on my XP laptop, once I had downloaded the USB driver. I did need to go into hardware manager to find out the com port number assigned. So far I have just done a loop test to check it is functioning (RS422), all seems OK. One suggestion is to purchase a short USB A male to female cable so the adaptor is not hanging off the computer's USB port. I found RealTerm software on the internet which works well with this device. G
