Product Description:
The CONTEC PIO‑32DM(PCI) is a high‑speed, bi‑directional digital input/output interface board designed for PCI bus systems. It provides 32 channels of TTL‑level digital I/O signals that can be configured as input or output in 16‑bit or 32‑bit units. The board supports bus mastering DMA for high‑speed data transfer up to 80 MB/s (133 MB/s maximum theoretical PCI throughput) without CPU load. It is suitable for applications requiring rapid digital pattern generation, high‑speed sampling, or synchronized multi‑board operation.

### 2. Key Features

- High‑Speed Bus Mastering:
Supports PCI bus master DMA transfer at up to 80 MB/s, enabling direct memory access between the board and PC memory without CPU overhead.

- Flexible I/O Configuration:
32 TTL‑level digital channels configurable as 32‑bit input, 32‑bit output, or 16‑bit input + 16‑bit output.

- High‑Frequency Pattern I/O:
Capable of 20 MHz sampling (input) and 20 MHz pattern generation (output).

- On‑Board FIFO Buffers:
1 K‑word FIFO memory per channel (input and output) ensures stable high‑speed data flow.

- Synchronization Control (SC) Connectors:
Enables inter‑board synchronization for up to 16 boards, allowing simultaneous operation across multiple channels or systems.

- Interrupt and Timer Functions:
Four input lines (DIOA00–DIOA03) can generate software‑controlled interrupts on rising edges. An integrated timer provides precise timing even under Windows OS.

Includes REQ/ACK handshake lines and external start/stop/clock inputs for precise control of pattern I/O.

- Software Support:
Bundled with CONTEC’s API‑PAC(W32) driver library for Windows and API‑DIO(LNX) for Linux, supporting Visual C/C++, Visual Basic, Delphi, Builder, gcc, and Kylix.

- General‑Purpose I/O Mode:
Can function as a standard digital I/O board when bus mastering is not required.

2. 16‑bit Input / 16‑bit Output Mode – simultaneous bidirectional operation.
3. 32‑bit Output Mode – generates digital patterns at up to 20 MHz.

Use Cases and Applications:
- High‑speed digital pattern generation and acquisition
- Automated test equipment (ATE)
- Logic analysis and signal monitoring
- Industrial automation and control systems
- Data acquisition synchronized across multiple boards
