The 7904 is a 3U compact PCI serial interface that provides four 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. 16C864 UARTs with deep 128-byte FIFOs are standard to reduce system overhead, even at high speeds.
