3.4 Analog Output Connections

The PCI-1710/1710HG card provides two D/A output channels,
DA0_OUT and DA1_OUT. Users may use the PCI-1710/1710HG
internally provided precision –5V (-10V) reference to generate 0 to +5 V
(+10 V) D/A output range. Users also may create D/A output range
through external references, DA0_REF and DA1_REF. The maximum
reference input range is +/-10 V. Connecting with an external reference
of -7 V will generate 0 to +7 V DA output.

Figure 3-5 shows how to make analog output and external reference
input connections on the PCI-1710/1710HG card.
