The OMG-COMM4-LPCI-DB25 low-profile PCI serial interface provides four RS-232 serial ports capable of data rates to up 460.8K bps. Each RS-232 port implements all modem control signals for maximum compatibility with a wide range of peripherals. The board is MD1 low-profile and universal bus (3.3V and 5V) compatible and utilizes a 16C864 UART to provide 128-byte Tx/Rx FIFOs for maximum reliability in data intensive applications. It includes a one-meter cable that terminates to four DB25M connectors. It is designed for the chemical, automotive and water industries. Recommended applications include HVAC, chemical processing, environmental monitoring and lab use. The board is CE compliant.
