The default operation for the IF Box reverse gear signal is
from Low to High (0VDC to +12VDC). Measure the reverse
gear signal voltage at the interface box in the active and
non-active state. If the reverse gear signal is different than
the default value, the DVM will need to be reconfigured
using the VuVault software.
