The DCB RS-422 to RS-232 interface converter is a compact 1” high by 2.5” wide by 3” long. The converter is externally powered. It is available in a 6 to 37 volt model and a 36 to 72 volt model. All of these units are high and low temperature rated.

The unit converts RS-232 to RS-422. It can also be used on RS530 and V.35 (transmit and receive data only).

Typical application is from a 9-pin RS-232 device to an RS-422 device. Note that control leads are not passed through or converted.

The RS-422 leads are balanced, with 2 output wires, and 2 input wires. On the interface converter, the green connector is RS-422. Input into the converter is through the RX pins. Output from the converter is through the TX pins.

The 9-pin connector is the RS-232 interface. Pin 2 is Receive Data, data into the adapter, pin 3 is Transmit Data, data out of the adapter, and pin 5 is Signal Ground. All the other pins on the 9-pin connector are unused.
