The PMC-HPDI32A-ASYNC is a full-duplex RS-422/485 serial I/O board. Each channel can operate up to 5M bits/ s. FIFO buffers up to 512K-byte for both transmit and receive (1M byte total) provides for a smooth and efficient interface between the serial interfaces and the host computer. The high speed async transmit/receive is implemented in an FPGA and provides for protocol flexibility. It features a full duplex DMA interface.
