For each BNC connector that you use for two channels, set the source type
switch to the GS position. This setting disconnects the built-in ground
reference resistor from the negative terminal of the BNC connector,
allowing you to use it as a single-ended channel, as shown in Figure 4-11.
When you set the source type to the GS position and configure the device
for single-ended input, each BNC connector provides access to two
single-ended channels, ACH<
i
> and ACH<
i
+8>. For example, the BNC
connector labeled
ACH0
provides access to single-ended channels ACH0
and ACH8, the BNC connector labeled
ACH1
provides access to
single-ended channels ACH1 and ACH9, and so on.

Connecting Analog Output Signals
The AO signals are DAC0OUT, DAC1OUT, EXTREF, and AOGND.
DAC0OUT and DAC1OUT are the voltage output signals for AO channels
0 and 1, respectively.
