General Product Information

Two Channel RS-232 to RS-422 Converter allows your computer to communicate up to 4000 feet by converting the RS-232 signal to RS-422. If the peripheral to be connected will operate on the RS-422 signal, only one converter is required. If both the Data Transmitting Equipment and Data Receiving Equipment use only RS-232, then two converters should be used, one at each end of the line. This model supports TD and RD signals and is powered by the RS-232 port handshake lines.

The RS-232 side has a DB25 female connector and the RS-422 side has a DB25 male connector.
