6.2.2 VR Assignment of cPCI/PCI-6208 and PCI-6216
There are either 8 or 16 voltage output channels depending on which
model of the card is used. For each channel, two VRs are used to adjust
for the range and offset of the output voltage. The following table shows
the assignment and function of each VR. You can find these designators
on the PCB.

Table 5. VR Assignment
Note: For PCI-6208V/6216V (REV: B1 or later), the designator of VRs
are changed to VRm_n, where m = 0 ~ 15 and n = 1 or 2.
Example VR6-2 on PCI-6208V/6216V REV: A3 will be changed
to VR6_2 on REV: B1 or later.
