  • The 422LPCOR converts unbalanced RS-232 signals to balanced RS-422 signals. It converts RS-232 TD and RTS to RS-422 and the RS-422 RD and CTS to RS-232. The converter is powered via the transmit data line (pin 2) and the handshake control lines (pins 4, 5, 6, 8 and 20). The converter can derive power from these lines when they are in the positive or negative voltage state. This permits the 422LPCOR to be used in applications without any regard to software control of the handshake lines.

    If no handshake lines are available, the converter can drive limited cable lengths using the transmit data line only. An external power supply can also be used if long distance communication is required and no handshake lines are available. The 422LPCOR can reach speeds of 115.2 kbps at 4000 foot distances.
