SW485C(Port-powerd RS232 to RS485/422 Converter)


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.

    Features
    1. Plug-and-Play, small volume, easy installation 
    2. Port-powered, high efficiency obtain electricity, can also worked on 3 lines
    3. RS-232 to RS-485 or RS-232 to RS-422
    4. Lowest consumption
    5. Automatic send data control, auto distinguish and sense direction adopt data transfer
    6. Auto sense serial signal rate, zero delay automatic transmit
