Features

Model 422LP9R is a port-powered two-channel RS-232 to RS-422 converter. It converts TD and RD RS-232 lines to balanced RS-422 signals. The unit is powered from the RS-232 handshake lines DTR and RTS. One of these handshake lines must be asserted (high) in order to power the unit.

• Converts RS-232 TD and RD to balanced RS-422 signals
• Extends RS-232 line up to 1200 m / 4000 ft
• Port-powered from RS-232 asserted handshake lines - no power supply required
• Data rates up to 115.2 Kbps
• DB9 F / DB9 F
• 4.7K Ohm biasing resistors
