Q: What tools are needed to install the vehicle computer (vehicle terminal)?
A: The tools needed are:
1. Multimeter: It is used to detect the positive and negative of the power supply, and to find out the electric level working condition.
2. Phillips screwdriver: used to fix the GPS vehicle computer.
3. Electric drill: Used to punch and fix GPS vehicle terminal equipment.
4. Wire cutters: used to cut excess threads.
5. Wiring harness: Used to bundle the installed power cable so that the cable is beautiful.
6. Adhesive tape: Short circuit at the place where the electricity is prevented from being connected.
7. Double-sided tape: Used to fix GPS and CDMA antennas.
Q: How to correctly place the GPS/CDMA antenna?
A: The GPS antenna needs to be placed in a balanced manner with its back to the sky. The top of the GPS antenna should be able to normalize the positioning satellite. It is recommended that the GPS antenna be fixed on the roof of the cab and the bottom of the antenna be insulated from the vehicle body. The CDMA antenna can be placed anywhere that can receive CDMA signals, but the bottom of the antenna needs to be insulated from the body.
Q: What precautions should I take for the power supply?
A: Take the power supply should ensure that the power supply voltage is pure enough, that is, the interference of other electrical appliances in the car is small, otherwise it will easily affect the vehicle terminal work and even burn the vehicle computer. Ensure that the negative pole and the body of the vehicle have the same potential, and especially the large models powered by two 12v batteries in series cannot be connected to a single 12v battery in the rear pole. Otherwise, the vehicle terminal and other electrical equipment in the vehicle may be burned.
Q: What do you need to pay attention to when fixing the vehicle computer (vehicle terminal)?
Answer: The vehicle computer (vehicle terminal) needs to be insulated and fixed, which is the vehicle terminal metal shell must not touch the metal parts of the vehicle body. Factors such as non-dampening and excessive exposure must take into account for vehicle computer location, and it is recommended that it be fixed in the vehicle interior or inverted to the bottom of the seat.
Q: How to determine the power-on of the vehicle computer (vehicle terminal) is normal?
A: When the system is initialized, the green light is on for three to four seconds. Then the light turns red and flashes once every 5 seconds to indicate that the system is operating normally; the red light indicates that the system is on the line; the red light flashes once every second to indicate that the CDMA is online and the GPS has been located; the red light flashes quickly to indicate that the GPS is located but not yet on the line. If there is no indicator light, please check whether the power cable is connected properly.
Q: Will the positive and negative poles of the power supply be reversed?
A: No, the power cable is designed according to electrical standards. The red color is the positive pole and the black is the negative pole. Power supply wiring square socket pin 2 and 11, pin 2 is positive, and pin 11 is negative, the power supply can be 9-30v DC voltage.
Q: Is the vehicle computer (vehicle terminal) waterproof and shockproof?
A: It is not waterproof and shockproof.
Q: How much power is consumed in the vehicle computer (vehicle terminal)?
A: The vehicle computer has the function of low power consumption; operating current≤300mA, quiescent current≦160mA.
Q: The normal working environment of the vehicle computer (vehicle terminal)?
A: The normal working environment: the working voltage is 9v～30v, working temperature: -10℃～+60℃.Frequently Asked Questions -
