VR Assignment
There are five variable resistors (VRs) on the PCI-1710/1710HG card
and three variable resistors (VRs) on the PCI-1710L/1710HGL card.
These variable resistors are to facilitate accurate adjustments for all A/
D and D/A channels. Please refer to the following two figures for the
VR positions.
