Supplying Power to Devices Connected to the Unit

Cameras and most other peripherals connected to the CVG-M unit usually require independent power supplies.

These devices should be connected directly to the vehicle battery (or some other power source).

NOTE: In some cases, it may be possible to provide power to certain devices through the 12VDC Power Out

connector on the rear panel of the CVG-M. This option is not appropriate for supplying power to

cameras. For additional information, see Using the 12VDC Power Out Connector, page 36.

Turning the Device Power On and Off with the Ignition

When the CVG-M is installed in a vehicle, it is normally configured to shut down whenever the vehicle ignition is

turned off. All devices that draw their power through the 12VDC Power Out connector on the CVG-M are also

turned off when the CVG-M shuts down, because they do not receive any power from the unit. If you want devices

that are directly connected to the vehicle battery to also shut down when the vehicle ignition is off, you should route

the power supply through the activator connector (Out1) on the CVG-M unit, as illustrated below.
