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
Review: The most pro handled small products - Recently, I got my small items from other sellers. I wish they will learn from DSD TECH company how to deliver a product. As seen in pictures, packed well, user manual, and CD for drivers. Trustable, day after delivery at the time. No more words. EXCELLENT !!!!

### ⭐⭐⭐ OK, but would be better with addition of a +5v terminal.
*by D***T on 25 December 2020*

This works OK, but it's annoying not to have a 5v terminal like a lot of other adapters.
