Battery Level on Driver Station

How do you read the battery level on the driver station? I think I saw something about the analog module, but to be safe, I need help.

Thank you in advanced and Happy Competitions!

You put a jumper on the outer two pins on the Analog Module. There is a picture in the Manual.

[R64]

A National Instruments 9201 module must be installed in slot 1 of the  cRIO .  An analog breakout must be connected to this module. A jumper  must be installed in the “Power” position (two outer pins) on the analog  breakout (see Figure 4‑10).  The analog breakout must be powered from  the PD Panel.
