CPCI-MPSIO4 4-channel Serial I/ O with software selectable transceivers The CPCI-MPSIO4 board is a low cost 4-Channel UART with software selectable Serial I/ O cable interface transceivers. Each channel can be software configured for RS-232, RS-422A, RS-449, RS-485, V.35, EIA-530, EIA-530A and V.36. The board can support up to 10 Mbits/sec for differential interfaces and 120 Kbps for single ended operation. Each transmitter and receiver has a 128 byte deep FIFO. The board is fully software compatible with 16C550 family of UARTs. The Serial I/O is through the front panel. Features Include: · Four 16C950 High performance UART channels. · UARTs fully software compatible with 16C550 type devices. · Asynchronous and Isochronous communications protocols. · 128 Byte deep FIFO per Transmitter and Receiver. · Flexible Clock Prescaler from 1 to 31.875. · Automatic in-band flow control using programmable XON/XOFF in both directions. · Automatic out-of-band flow control using CTS#/RTS# and/or DSR#/DTR# · Arbitrary trigger levels for Receiver and Transmitter FIFO Interrupts. · Global Interrupt status and readable FIFO Levels to facilitate efficient device drivers. · Operation via IO or Memory Mapped device registers. · Detection of bad data in the Receiver FIFO. Applications Include: ü LAN/WAN Networking ü Telecommunications ü Serial Interface Functional Description: The CPCI-MPSIO4 is an easy-to-use four channel full-duplex serial I/O board with software selectable transceivers. Each channel can operate up to 10 Mbits/s with a differential cable interface and 120 Kbps for single ended cable interfaces. The board is based on the Oxford Semiconductor OX16PCI954 which offers four 16C950 serial channels and the PCI interface in one space saving package. Each channel in the OX16C954 offers 128 byte deep transmitter and receiver FIFOs. The deep FIFOs reduce CPU overhead and allow higher data rates. Each channel is also software compatible with the widely used industry standard 16C550 family of devices. The board only requires simple read/write statements to operate. The UARTs are connected to the cable interface using Sipex SP504 transceivers, supporting multiple protocols in a single transceiver package.
