Main parameters used:

1. Digital I/O (DIO)

Channels: 32 channels, 5 V TTL/CMOS bidirectional DI/DO

Configuration: Software selectable 32DI/32DO/16DI+16DO

Level standards:

Input: Low ≤ 0.8 V; High ≥ 2.0 V (5 V TTL)

Output: Low ≤ 0.5 V @ 24 mA; High ≥ 2.4 V @ 24 mA

Maximum rate: 20 MHz (80 MB/s, 32-bit parallel) ADLINK

Transmission width: 8 / 16 / 32 bit selectable

2. Auxiliary I/O

4 auxiliary DI (TTL)

4 auxiliary DO (TTL)

Purpose: Trigger, handshake, status indication, external interlock

3. Cache and data transmission

On-board FIFO: 64 KB (32K × 16 bit), supports loop / single mode ADLINK

DMA: Bus master control, scatter-gather DMA, reduces CPU usage

Transmission mode: Software polling / interrupt / DMA / handshake (Handshaking)

Data generation: FIFO repetitive waveform, custom mode continuous output

4. Clock and trigger

Internal clock: 1 MHz ~ 20 MHz programmable timer ADLINK

External clock: Supports TTL level input (up to 20 MHz)

Trigger: Independent digital edge trigger (rising/falling), used to start acquisition / generation

Synchronization: Supports multi-card synchronization, RTSI (optional)

5. Electrical and environmental

Power supply: +5 V @ 1.2 A (typical)

Operating temperature: 0 ~ 55 °C

Size: Standard half-length PCI card (175 × 107 mm)

Terminal matching: On-board selectable active terminal (high-speed long-distance transmission)

6. Typical applications

High-speed digital signal acquisition / playback (logic analyzer, protocol simulation)

ATE automated testing (parallel testing, vector generation, load simulation)

Industrial high-speed pipeline, encoder / sensor data capture

Parallel interface (such as parallel port, custom bus) simulation

High-speed closed-loop control, pulse sequence generation
