Testimonials

"I am communicating with kWh (energy) meters that have the RS485 built in, the port-powered converter's auto-turnaround feature works really well for my application, and I don't have to change any configuration."
Peter
"You have a great product.  Plugged it in and it worked right out of the box.., on the first try. Thanks for saving my old serial port devices in a world that thinks newer is better.  I am glad there are people like you who provide the compatibility that the industry doesn't care about anymore."
Chester
"232Analyzer is a nice piece of software. It's checksum calculator helped me to analyze pretty tough serial communication protocol."
