3 Port cPCI Card

The GX3903 is a 3-port, cPCI asynchronous communications interface board supporting RS232 and RS422 levels. Optionally, the board can support RS485 signaling. Each port is configured at the time of order for RS232, RS422 or RS485 signaling. The default configuration is RS232. For RS232 mode, each port supports RTS, CTS, TXD, RXD, DCD, DRC, DSR, and RI signaling. The RS422 mode supports TXD, RXD, CTS, and RTS with each line operating differentially with a uni-directional drive.
