Page 15: Register-Level Programming
Chapter 1 Introduction Register-Level Programming The final option for programming any National Instruments DAQ hardware is to write register-level software. Writing register-level programming software can be very time-consuming and inefficient and is not recommended. Even if you are an experienced register-level programmer, consider using NI-DAQ, LabVIEW, or LabWindows/CVI to program your National Instruments DAQ hardware. -

Pins 1 through 8 are analog input signal pins for the 12-bit ADC. Pin 9, AISENSE/AIGND, is an analog common signal. You can use this pin as a signal ground connection to the DAQCard-1200 in RSE mode, or as a return path in NRSE mode. Pin 11, AGND, is the bias current return point for differential measurements. -
Page 27: Figure 3-2. Daqcard-1200 Instrumentation Amplifier
How you connect analog input signals to the DAQCard-1200 depends on how you configure the card analog input circuitry and the type of input signal source. With different DAQCard-1200 configurations, you can use the instrumentation amplifier in different ways. Figure 3-2 shows a diagram of the DAQCard-1200 instrumentation amplifier. -

A/D conversions. All signals must be referenced to ground, either at the source device or at the DAQCard-1200. If you have a floating source, you must use a ground-referenced input connection at the DAQCard-1200. If you have a grounded source, you must use a nonreferenced input connection at the DAQCard-1200. -
