Installation Method
1.Install ADLINK Driver & Software Package：Software Setup。
Download and run the ADLINK U-DAQ driver installer or PCIS-DAQ software library. Complete driver installation before plugging in the hardware.
2.Wire Sensors to Terminal Block：Wiring Setup。
Connect sensor leads to the removable screw terminal block. Use shielded twisted-pair cables for analog inputs to minimize EMI noise.
3.Connect USB Cable to Host Computer：Physical Setup。
Plug the USB cable into a USB 2.0/3.0 port on the PC. The host system will automatically detect the device and enumerate the USB-1605.
4.Run ADLINK Hardware Test Utility：Diagnostics。
Launch the U-DAQ Creator utility to test analog input channels, verify voltage readings, and confirm counter functionality.
Operating Instructions
Single-Ended vs. Differential Selection: Configure analog input modes in software—use Differential Mode for noisy environments or floating sources, and Single-Ended Mode to maximize available channel count (16 channels).
Sampling Rate Tuning: Set aggregate sampling rates according to Nyquist criteria (at least $2\times$ the highest signal frequency; recommended $5\times\text{ to }10\times$ for precise waveform reconstruction).
Grounding Best Practices: Ensure sensor signal grounds are tied to AGND on the USB-1605 to prevent ground loops and erroneous voltage offsets.
