General Product Information

The 4WSD9TB Universal Converter provides RS-232 to RS-422/RS-485 conversion using either port-power or an external power supply. Unlike converters which require programming hardware handshaking signals to control RS-485 or RS-422 operation, the 4WSD9TB provides automatic control. The operating mode is set with 4 switches.

The 4WSD9TB is powered by the RS-232 signal lines. If this does not provide enough power, a DC jack is provided to connect a 12VDC supply.
