SW485C(Port-powerd RS232 to RS485/422 Converter)
The SW485C is an industrial grade bi-directional port-powered RS-232 to RS-485 or RS-422 converter in a 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 a RS-485 or RS-422 signal and vice versa. The unit is powered from the RS-232 data lines. It also supports data direction auto-turnaround. Therefore, no external power or flow control is required. The data direction auto-turnaround 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 either a DB9 male connector or 5 bit terminal block on the RS-485/422 side.
