The CPCI-SIO4ARHM and its transition module make a four channel full-duplex RS-422/485 serial board set. Each serial channel of the CPCI-SIO4ARHM can operate up to 10 Mbits/s in synchronous mode. Optional 32 Kbyte FIFO buffer for both transmit and receive (256 Kbytes Total FIFOs) data on each channel provides for a smooth and efficient interface between the serial interfaces and the host computer. The board is based on the Zilog Z16C30 high speed Integrated Universal Serial Controller (USC) which supports Asynchronous, Isochronous, Bisync, Monosync, HDLC, SDLC, External Sync and Nine-Bit protocols. The USC chip provides full duplex operation with baud rate generators, digital phase-locked loop for clock recovery and a full duplex DMA interface. One of the rear transition module is required and is priced separately. The module is available with RS-422/485 or RS-232 transceivers. Contact General Standards for pricing and availability. The CPCI-SIO4ARHM also has a PMC host site to allow customers to create more compact system solutions. Customers can mount any PMC board, including General Standard's PMC-SIO4A board. The CPCI-SIO4ARHM and the PMC-SIO4A combination will provide eight serial ports in a single CPCI slot.
