I used this to communicate to temperature controllers, I wired to the terminals and it worked, nice converter!
Easy to setup and use. Seems to be good quality for the money. I will now look to see how many years of service this provides.
I purchased this to program modules used in commercial applications. Not having time to test it in advance I took it to a customer site hoping it would work. I plugged it in and inserted the disk that came with it. It seamlessly loaded the drivers and I was able to connect and finish my work. Suggestions to improve the product. Decrease the brightness of the power LED and change the color to GREEN. Increase the brightness of the TX and RX LEDs.
