Working Principle
The PCI-6110 samples analog input signals using a 12-bit pipeline ADC. Selected channels are converted at high speed and stored in an on-board FIFO before being transferred to the host computer through the PCI bus. The analog output section generates voltage waveforms from digital values using a 16-bit DAC. Digital I/O lines read or drive TTL/CMOS signals, while counter/timer resources measure frequency, period, or pulse events. Triggering can be sourced from internal timers, external PFI lines, or the RTSI bus to synchronize acquisition with other instruments.

Installation Requirements

  • Install the card into a compatible PCI slot.
  • Verify that the host power supply can provide up to 2.5 A at +5 V for the PCI-6110.
  • Connect analog signals using shielded cables and proper grounding.
  • Observe the maximum working voltage and overvoltage protection limits.
  • Configure input coupling, range, and sampling rate in NI software.
  • Use RTSI or PFI connections only when multi-device synchronization is required.
  • Install the correct NI driver before commissioning.

Precautions for Use

  • Do not exceed the ±42 V overvoltage protection limit.
  • Verify input coupling and range settings before applying signals.
  • The 12-bit resolution is lower than 16-bit M Series or X Series devices.
  • High-speed sampling generates large data volumes; ensure sufficient host memory and bus bandwidth.
  • Avoid shorting analog output channels to high-voltage sources.
  • Confirm exact channel count, accuracy, and environmental ratings from the official PCI-6110 user manual.
