description

No power supply required

Convert RS-232 TD and RD signals to RS-422, allowing range to be increased from the 50 feet specified in the RS-232 standard to 4,000 feet at data speeds up to 115.2 kbps. No handshake driver control is required as the RS-422 driver and receiver are always enabled.

These port powered models require no external power supply, drawing power from the RS-232 handshake lines. If no handshake lines are available, choose Model 422PP9TB or 422LPCOR and connect a 12 VDC power supply to the terminal block.
