Testimonials
"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
"I am communicating with kWh (energy) meters that have 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 configurations."
 Peter
"232Analyzer is a nice piece of software. It's checksum calculator helped me to analyze pretty tough serial communication protocol."
