Four-cored aviation port
No. Function
1 12V external power source and no more than 1.5A.
2 Ground line
3 Audio port
4 Video port
Video Output
The Device is provided with one CVBS (PAL/NTSC 1.0V
P-P
, 75Ω) port, and supports the simultaneous
output from these two ports.
Read the following contents carefully before using the computer instead of monitor.
To extend the Device life, do not keep the Device running for a long time.
Regular demagnetizing helps keep the monitor working properly.
Stay away from devices with strong electromagnetic interference.
Audio output
The audio output signal parameter is larger than 200mv 1KΩ. The audio output port can directly
connect to the display with audio function on the vehicle or active speaker, and the port can also
drive other sound output devices through amplifier.
Alarm Input and Output Connection
Before using the alarm function, learn about the connections method of alarm input and output
port.
Alarm Input
The alarm input port supports alarm signal from ground and device of 12V-24V voltage.
If the alarm device is connected to the Device and other devices, use relay for isolation.
Alarm Output
The alarm output port cannot be connected to high-power load (less than 1A). When constructing
the output circuit, the excessive current should be prevented from causing damage to the relay. Use
the contactor for isolation when applying high-power loads.
