3. Connect the power supply cable to the Power connector on the unit.
4. Plug the power-connector cable into the outlet.
Connecting the Unit to the Vehicle Battery
Normally, the unit is connected to the vehicle battery and to the ignition using 16 AWG cable (not supplied). This
can be done in one of two ways:
• Connecting the unit directly to the battery and the ignition
• Connecting the unit to a power source in the vehicle that is only active when the ignition is on
When the unit is connected to the battery and ignition in one of these ways, it automatically powers up when the
ignition is switched on. If the unit is connected directly to the battery, it can be configured to operate only when the
vehicle ignition is on or to shut down automatically soon after the ignition is turned off. Otherwise, it will shut
down automatically when the ignition is turned off.
For testing and evaluation purposes, the unit can also be powered by connecting it to the vehicle’s cigarette lighter,
if the vehicle has one. This method connects the unit to the battery and the ignition quickly and easily, but it is not
normally suitable for permanent connections, because it is difficult to install the unit and the wiring securely in
appropriate locations when this method is used.
In addition, it is possible to connect the unit to the battery alone, without connecting it to the ignition. In this case,
the unit runs continuously, whether the ignition is on or not, as long as the battery can supply power to it. Because
of the drain on the battery, connecting the unit in this way is also only recommended for limited periods of time for
testing and evaluation purposes.
NOTE: The ignition connector (IGN) of the Power connector MUST be connected. If it is not, the unit will not
start. If you wish to use the vehicle’s ignition connection, connect it to this connector. Otherwise, short
this connection to the positive (+) connector of the Power connector block. For additional information,
see step 4 below (pp. 30–31).
NOTE: To connect the unit only to the battery, 16 AWG red and black cable (not supplied) is required.
WARNING: It is very important to ensure that the unit is connected to the power source in such a way that there
are no voltage fluctuations when the unit is in operation. Voltage fluctuations can interfere with the
timestamps of recorded video, making it impossible to retrieve the video from the unit's storage
media.
To connect the M VG200 to the vehicle battery:
1. If the wire connector is not plugged into the Power connector on the unit, plug it into the Power connector on
the rear panel of the unit, and tighten the screws to secure it.
