FAQ

Common Questions About Our Asset Trackers

  • Why is the speed limiter unable to obtain GPS location?

    • Locate whether the module is powered oninformation
    • Whether the antenna of the device is working properly
    • The software version resolution is abnormal
  • Why is my speed limiter device offline?

    1. IP address and port whether correct
    2. SIM Card Whether the payment is in arrears
    3. Whether the signal is normal
    4. Whether the protocol corresponds to the platform
    5. Whether the frequency band of the SIM is the same as the frequency band supported by the device
  • Why are SMS commands not working?

    1. The SIM card does not support SMS commands
    2. The device has an abnormal SMS response
    3. Permission number caused
    4. The SMS encoding method may affect the SIM card not replying command in some countries
  • When does the speed limiter system send alarms?

    1. Over speed alarm: When the vehicle exceeds the preset speed value, the device will sound and send an alarm to the platform.(Over speed)
    2. Disconnect the main power alarm: When the backup battery is turned on and the main power is disconnected, the device will send an alarm to the platform(POWER OFF)
    3. GPS antenna disconnection alarm: The device must detect the car’s GPS speed, which means the car must be moving and the GPS is valid, the device will send an alarm to the platform.
  • Why is the speed limiter not controlling the vehicle speed?

    1. Check whether has selected the correct speed mode
    2. Check whether the speed limit wire connected correctly
  • Could the devices support more features?

    Yes, we can provide driving data recorders and speed limiters with positioning and communication modules. They can support uploading location data, photos, and sound to the platform, ensuring data security and improving management and monitoring efficiency.

  • What should be noted when installing an antenna?

    To prevent signal interference, GSM/GPRS antennas should avoid entanglement with other control lines and maintain a distance of at least 50CM from wireless devices.

  • Are the devices suitable for all kinds of vehicle?

    We provide different speed-limiting solutions for different vehicles and models. Please contact us to confirm the corresponding solutions.

  • How does the speed limiter work?

    The device can read the vehicle’s speed through the pulse speed line, and identify the vehicle’s speed accurately. Then it will control the speed through a relay or pedal controller to prevent the speed from exceeding the threshold.
