Thông tin chi tiết


The SW485 is an industrial grade bi-directional port-powered RS232 to RS485 or RS422 converter in a 9 pin format. It can convert any standard full duplex RS232C port to any two-wire balanced half duplex RS485 port or four-wire balanced full duplex RS485 or RS422 port. In simple terms, it will convert any RS232 signal to a RS485 or RS422 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/RS422 driver when data is present on the RS232 side making the device plug-and-play, requiring no software drivers. The MW1040 has a DB9 female connector on the RS232 side and either a DB9 male connector or 5 bit terminal block on the RS485/RS422 side.
