General Product Information
The 4WSD9OTB provides RS-232 to RS-422/RS-485 full or half-duplex conversion. 2000 V Optical Isolators protect your equipment from dangerous ground loops and surges. Data is converted in both directions, RS-232 Transmit data is converted to balanced RS-422 or RS-485 Transmit, and Received RS-422/RS-485 signals are converted to RS-232. Unlike converters which require programming hardware handshaking signals to control RS-485 or RS-422 operation, the 4WSDO9TB provides automatic control. The operating mode is set with 4 switches.
