1. Notes
1.1 Definitions of connectors for aviation interfaces:
1 red: +12V positive pole
2 black: common GND
3 white: audio
4 yellow: video
1.2 Definitions of power cords:
Red: DC12V or 24V input
Black: ground GND
Yellow: ignition wire GND
1.3 Do the following to properly start the machine:
1. Lock the key lock (the lock is the switch of the machine);
2. Connect the red power cord to the battery positive, the black cord to the negative, the
yellow cord to the ignition wire of the car key (or ACC); or else, combine the red and yellow
cords as positive pole and black as negative.
Note:
1) Make sure the voltage of the battery is between 8V-36V before connection; otherwise,
the equipment may be burnt out;
2) With the cords connected, pay attention to the insulation between the cords to prevent
burning out of the battery due to short circuit of the cords;
3) Make the yellow cord is connected to the ignition wire; otherwise, the equipment will not
support delayed shutdown and the last video will be lost.
4) Note: the installation of on-board machine must use the positive and negative of the
battery instead of using bond strap as ground wire because bond strap will produce
negative impulse to disturb the normal operation of the host. The power cords for the
positive and negative power cord must be over Φ1.0mm in diameter.
