3 Port RS-232/RS-422/RS-485 Interface CPCI Cards
GX3903 Series
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.

4 Port RS-232 & 4 Port RS-422 Interface cPCI Card
GX3904
The GX3904 is an 8-port, cPCI asynchronous communications interface board supporting (4) RS232 and (4) RS422 signal levels. The four RS232 ports offer a full set of data and modem control lines configured for DTE operation. The four RS422 ports offer differential signaling and support DTE operation. Each RS422 differential pair is terminated by a 150 parallel resistor. An optional transition cable is available to convert the front panel SCSI connector to (8) DB-9, D-sub connectors.
