The PMC-HPDI32B-COS is a 32-bit parallel Change of State Detection board featuring high speed RS485 interface transceivers. The Change of State detection is can be customized to ignore specific bits and to provide an interrupt after a specified number of change of state events have occurred. The board will also function as a simple Logic Analyzer with a configurable trigger value and mask. The sample rate for both Change of State and Logic Analyzer is programmable from 20MHz down to 300Hz. Received values are buffered in an 8K deep on-board FIFO which is easily accessed by the integrated a DMA Controller. After the DMA is initialized and started, the host CPU will be free to proceed with other duties and need to respond only to interrupts. The DMA controller is capable of transferring data to host memory using D32 transfers; whereas the FIFO memory provides a means for continuous transmission of data without interrupting the DMA or requiring intervention from the host CPU.

The PMC-HPDI32A board is a fast and flexible bi-directional 32-bit digital I/O board that transmits and receives data up to 80 Mbytes (differential I/O) or up to 200 Mbytes (Pseudo ECL I/O) per second. The board is useful as a general purpose DMA interface to a variety of external peripherals. The DMA engine is capable of transferring data to/from Host memory using D32 block transfers, while the FIFO memory (up to One Mbyte of total FIFO) provides continuous transmission of data without interrupting the DMA transfers or requiring intervention from the Host CPU. The board has 7 bi-directional programmable handshake lines and eight pre-configured software selectable interface protocols to allow easy interfacing to most digital I/ O peripherals. Available transceivers are RS485/422 and PECL. For TTL and LVDS transceiver versions, please see the PMC64-HPDI32ALT.

The PMC-HPDI32A-DIPHASE is a full-duplex RS-422/485 serial I/O board. Each channel can operate up to 10M 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 di-phase transmit/receive is implemented in an FPGA and provides for protocol flexibility. It features a full duplex DMA interface.

The HPDI32A-COS board is a 32-Bit parallel digital input board that samples input data (via the cable interface) at selectable rates. The board can detect any Change-of-State and store the changed data word data in the on-board FIFO. The board is programmable and can generate an interrupt on the first detected change or upon any desired number of changes. Deep FIFO buffers (128 Kbytes) allow data bursts to be transferred over the PCI bus independent of transfers over the cable. Change-Of-State boards allow for more efficient monitoring of peripheral or industrial type devices (transducers, etc.). The board can also be used in a (logic analyzer) type mode by storing up to 64,000 samples after receipt of a trigger word. FIFOs, DMA engine, PCI controller, differential receivers, and multiple status interrupts provides high bandwidth along with complete board control.

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.
