SW485C

The SW485C is an industrial-grade bidirectional RS-232 to RS-485 or RS-422 converter with 9-pin format. It can convert any standard full duplex RS-232 port to any two-wire balanced half-duplex RS-485 port or four-wire balanced full duplex RS-485 or RS-422 port. In simple terms, it will convert any RS-232 signal to an RS-485 or RS-422 signal and vice versa. The unit is powered from RS-232 data lines. It also supports automatic data direction steering. Therefore, no external power or flow control is required. Data steering auto-routing automatically enables the RS-485/422 driver when data is present on the RS-232 side, making the device plug-and-play, requiring no software drivers. The SW485C has a DB9 female connector on the RS-232 side and a DB9 male connector or 5-bit terminal block on the RS-485/422 side.
