True plug-and-play
Worked first time. Easy to use. It became COM4 on Windows 11 without requiring any driver installation.

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

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 !!!!

Great little adaptor - I will be buying more!
RS422 can be a trial to get working - but with this device it just worked perfectly first time. The labelling on the back is clear and meaningful. The indicator LEDs are a really useful feature.

OK, but would be better with addition of a +5v terminal.
This works OK, but it's annoying not to have a 5v terminal like a lot of other adapters.

OK, a bit delicate.
Worked for a few weeks, now dead.

会社で使用しているお高いコンバーターをうっかりドライバーが入らない状態にしてしまい代用として購入しました。 付属のCDでドライバーが各種あり、すんなり認識してポート合わせたらあっさり使えました。安いし満足です。 当方RS485用として購入しました。
