There is always the need of RS232 to RS422 converters in high speed local area networks, where the throughput is in kbps and not mbps. The distance over which the RS232 device can operate these converters can extend, and the conversion of signals between different protocols is also facilitated by them.


It is first necessary to understand what RS232 is in order to understand how to use an RS232 to RS422 converter. For quite some time the RS232 has been around and to support asynchronous as well as synchronous data transmission between PCs, modems and other data communication devices, has the ability. Receiving as well as transmitting data at speed of upto 20 kpbs the RS232 port has a 9-pin or 25-pin connector. However, not more than 15.2 metres, or 50 feet, the distance of the connection should be located. But it will necessitate the use of RS232 to RS422 converters if the distance of connection is beyond this. These converters are able to transmit data and signals to a distance of upto 4,000 feet. Wherein one pair of wires is used for transmitting, while the other pair is used for receiving this is primarily because the RS422 has a 4-wire system.
Ranging from 300 bps to 115 kps in both directions the RS232 to RS422 converter typically supports speeds. And, by the RS232 port, the power for the converter is supplied, but through an external source provided the model has the facility, it can also be powered.
Typically, the female of the connector is connected on the RS232 port side, while the male is connected on the RS422 side. And there is also a possibility of even multi-port connections.
