The 3onedata SW485C is a small plug-in converter that converts the RS-232 TXD and RXD signals to RS-485 and RS-422 signals. It is powered from the handshake lines on the RS-232 serial port so no external power source is needed. It automatically converts from full duplex RS-232 to half duplex balanced RS-485 port or four-wire balanced full duplex RS-422. No configuration or programming is necessary. Suits serial data up to 115200 bps.

The SW485C has a DE-9 female connector on the RS-232 side and a DE-9 male connector with 5 way screw terminal adapter on the RS-485/RS-422 side.
