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.
12 VDC external power is required. Optional Power Supply 422PS is matched to this unit.
The RS-232 side has a DB25 female connector and the RS-422 side has a DB25 male connector. CE approved.
For reversed gender see 422CON.
