IT-SC485WA-SW
Port-Powered RS232 to RS-485 Converter
The IT-SC485WA-SW is an industrial grade bi-directional port-powered 2500V opto-isolated RS232 to RS485 converter in a 9 pin format. 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 a RS485 signal and vice versa. The unit is powered from the RS232 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 RS485 driver when data is present on the RS232 side making the device plug-and-play, requiring no software drivers. The IT-SC485WA-SW has a DB9 female connector on the RS232 side and either a DB9 male connector or 3 bit terminal block on the RS485 side.
