Differential input mode
When all channels are configured for differential input mode, eight analog input channels are available. In this
mode, the input signal is measured with respect to the low input. The input signal is delivered through three
wires:
 The wire carrying the signal to be measured connects to CH# IN HI.
 The wire carrying the reference signal connects to CH# IN LO.
 The third wire, typically a system ground, connects to LLGND.
Single-ended input mode
When all channels are configured for single-ended input mode, 16 analog input channels are available. In this
mode, the input signal is referenced to the board's signal ground (LLGND). The input signal is delivered
through two wires:
 The wire carrying the signal to be measured connects to CH# IN HI.
 The second wire connects to LLGND.
