2.4:BRIEF INSTRUCTION OF COMMONLY USED INTERFACE CABLE
Power cable:
As the following map shows, one end is a white plug with 6 pin, connect to the white of the equipment's
back pannel. Red and black cable to connect to the car's battery directly. The red cable is connected to
the positive electrode, the black cable is connected with the negative pole .The yellow cable is
connected to the ignition line. Mainframe equipment opens automatically after opening the car with the
car key. Autodelay closes after closing the car . The yellow cable connects to the gear where the

1.Ensure the battery voltage is between 8V-36V before connection. Otherwise, it
will burn out the equipments .
2.After the cable is connected . please note the insulation between the power line .
Prevent burn out the battery because of the short circuit .
Functional MDVR approximately has above kinds of accessories,the 4 pin test cable is just used
during the test, please do not use it on the installation. When installed, recommend to use the 4 pin
audio extended cable. Function model MDVR need to use the 4 PIN-AV when connect to the audio
input . it doesn't need to use this cable if it is only video input, and use the AV interface in the front
panel only. External interface of functional MDVR can choose from WIFI/3G/GPS, so the relative
module antenna is needed . Video cable of the simple MDVR is aviation head. So there will be
some differences between the corresponding interfaces .As Figure 2-11.
