TCP468 3U CompactPCI 4 Port Serial RS422 High-Speed Serial Interface

3U CompactPCI card with 4 high performance RS422 serial ports. All RS422 ports have RxD±, TxD±, RTS±, CTS±, DCD± and DTR± lines. The TEWS Technologies module offers a front panel I/O with a DB-50 type connector. On-board termination is provided for all output signals.

Each channel has 64 byte transmit and receive FIFOs. The FIFO trigger thresholds, and the baud rates are individually programmable: up to 5.5296 Mbps. All channels generate interrupts on PCI interrupt INTA. For fast interrupt source detection the UART provides a special global interrupt source register. All channels use transceivers with 15 kV ESD protection.

A wide range of drivers is available: Linux, Integrity, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.
