Solution:

Analog Output Connection The PCI-1710/1710HG/1711/1716 provides two D/A output channels (PCI-1710L/1710HGL/1711L/1716L are not designed to have this function), AO0_OUT and AO1_OUT. Users may use the PCI-1710/1710HG/1711/1716 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, AO0_REF and AO1_REF. The external reference input range is +/-10 V. For examp le, connecting with an external reference of -7 V will generate 0 ~ +7 V D/A output. The attached file shows how to make analog output and external reference input connections on the PCI-1710/1710HG/1711/1716.
