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 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."

OPTO-ISOLATED USB TO RS232 / RS485 / RS422 CONVERTER

Isolated USB to RS232 RS485 RS422 converter

The USB-Serial-3 is an industrial-grade (wide temperature range with surge & static protection) optically-isolated USB to RS-232/485/422 converter, which can be used to convert any standard USB port into a three-wire RS-232 port, a two-wire RS485 port, or a four-wire RS422/RS485 port and vice versa.
