ADLINK DAQ-2000 Synchronous Sampling and Acquisition Card Selection Guide

Daily maintenance precautions:

Regularly check if the cable connector (68 pin VHDCI) is loose or oxidized;

Avoid plugging or unplugging signal lines while they are live to prevent damage from overvoltage;

Maintain a working environment temperature of 0-55 ℃ and a relative humidity of 5-95% without condensation.

Common problems and troubleshooting

Discontinuity or loss of A/D acquisition data: Check the DMA buffer size and Scatter Gate settings to ensure that the application reads data in a timely manner; Reduce the sampling rate or increase the FIFO depth (DAQ-2010 only).

Trigger not responding: Confirm that the trigger source wiring is correct (TTL level is required for digital triggering, and within the input range for analog triggering); Check the trigger mode settings (if pre triggering, fill the FIFO first).

Multi card synchronous phase deviation: Ensure correct SSI cable connection, correct master/slave card jumper or software configuration; All cards use the same external clock source (such as SSI synchronous clock).

Analog output amplitude error: Perform automatic calibration; Check if the external reference voltage (if used) is stable.

Digital I/O read/write failure: Check the direction setting of port 8255 to ensure that the port is correctly configured as input or output.
