Equipment and installation

Step1 ：GPS, 3G/4G and WiFi antennas are installed. The GPS, 3G/4G and WiFi antennas shown below are

connected to the corresponding positions of the rear panel of the MDVR, and a reasonable wiring is made, so

that the signal is not subject to external interference.。

Step2：Power line

A:Switch mode is set to "ignition" power connection mode：

When the system management, power management, boot mode, the switch is set to "fire", the white 6PIN

plug connection to the rear panel of the MDVR 6PIN power input interface cable, red and black is directly

connected to the car battery or level out after received total electric insurance after the red line connected to the

positive and negative black ground. The yellow line is connected to the ACC switch of vehicle ignition line, that

is, the gear switch before starting the motor. When the key is opened, the device will start automatically, and if

the vehicle key is closed, it will shut automatically.

B: switch mode is set to "timing" or product test, power connection mode。

When the system management, power management, boot mode, the switch is set to "time" or when the

device is used in non vehicular environment (such as bus stations, logistics station monitoring system) or

product testing, the red and yellow line twist into a power supply cathode, black separate grounding negative。

This end connects the

interface -557 connector

Prior to connection, the voltage is confirmed

to be 8V-36V, and if it exceeds this range, it

may cause damage to the equipment

The MDVR power line suggests direct connection to the positive and negative pole

of the vehicle battery, or the battery is connected to the positive and negative

pole after the safety box is connected. No connection to the metal conductor inside

the car as the ground, otherwise it will produce negative pulse interference normal

operation of the host, the positive and negative power supply wire diameter must

be more than 1.5mm. The installation host installed the equipment level to the

suitable position in the car according to the size of the hole position.

Step3：Alarm input and output line

A：Overspeed alarm connection

A:If the vehicle chooses the speed of GPS acquisition and requires the GPS signal to be normal, only the

relevant settings in the system menu, alarm settings and speed settings can realize the alarm function。

B:If the speed is chosen from the vehicle, the speed pulse sensor must be connected to the speed alarm. The

pulse sensor receives two lines of SPEED-A and SPEED-B on the port of our device. The connection schematic

diagram is as follows：

B：Alarm output connection

This machine provides 1 way alarm output, and uses the level output 200MA current to drive the external

alarm equipment. If you want to drive a more powerful device, you must connect the external relay, and refer to

the diagram as follows。
