SWA485

The SW485WA is a 2500V industrial grade two-way roll-on, opto-isolated RS232 to RS485 converter with 9-pin form factor. It can convert any standard full duplex RS232C port to any two-wire balanced half-duplex RS485 port. In simple terms, it will convert any RS232 signal to an RS485 signal and vice versa. The unit is powered from RS232 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 RS485 driver when data is present on the RS232 side making the device plug-and-play, requiring no software drivers. The SW485WA has a DB9 female connector on the RS232 side and a DB9 male connector or 3-bit terminal block on the RS485 side.
