SEA-7901

SEALEVEL 7901 COMM+2.cPCI

The 7901 is a 3U compact PCI serial interface that provides two RS-232, RS-422, or RS-485 serial ports for demanding automation and control applications. Each port can be field configured to RS-232, RS-422, or RS-485 for maximum flexibility. Our revolutionary Automatic RS-485 Enable circuit is included onboard to simplify multidrop network connections. 16C850 UARTs with deep 128 byte FIFOs are standard to reduce system overhead, even at high speeds. For user's that require custom baud rates, isochronous communications, or 9-bit protocol, the 7901 compact PCI serial interface is available with the Oxford 16C950 UART. Call for details.
