The GX3903 is a 3-port, cPCI asynchronous communications interface board supporting RS-232, RS-422, and RS-485 interfaces. Each port is configured at the time of order for RS-232, RS-422 or RS-485 signaling. The default configuration is RS-232. For RS-232 mode, each port supports RTS, CTS, TXD, RXD, DCD, DRC, DSR, and RI signaling. The RS-422 mode supports TXD, RXD, CTS, and RTS with each line operating differentially with a uni-directional drive.
