Vehicle Connections
When connecting to automotive power, it is expected that the ignition output will be +12 VDC, or +24 VDC
(following the battery voltage). Connect the Ignition Input (IGN) of the router to the ignition output of the
automobile. The DC In + and DC In - leads can be directly connected to the battery, but it is recommended
that they be connected after a fuse.
