Model 4WSD9TB has a terminal block RS-485 connector; Model 4WSD9R has a DB9 female RS-485 connector. Data is converted in both directions, RS-232 Transmit Data is converted to balanced RS-422 or RS-485 Transmit Data. Received RS-422/485 signals are converted to RS-232. Unlike converters which require programming hardware handshaking signals to control RS-422 or RS-485 operation, Models 4WSD9TB and 4WSD9R provide automatic Send Data Control. In RS-485 mode, the RS-485 driver is enabled by circuitry which senses the RS-232 TD input. In half-duplex RS-485 mode, the receiver is enabled when not transmitting. For full-duplex operation, the receiver is set always enabled. In RS-422 mode, the transmitter and receiver are always enabled. The operating mode is set with 4 switches see Table 1. The converters are powered by the RS-232 signal lines whether they are set high or low. If not enough power is available from the port, or no handshaking lines are available, a DC jack is provided to connect an external 12VDC supply. The DB9 female connector for RS-232 is wired as DCE (like a modem).

  • Change RS-232 TD and RD to RS-485 signals
