3. Synchronizing VCX Device Version with XENTRY

  • To ensure proper operation, the XENTRY Diagnosis software version must match the VCX device version.
  • If you manually install or update XENTRY software, and the versions don’t match, you will receive a warning message.

4. Common Issue: Device Unauthorized or Illegal Device

The following conditions may cause XENTRY versions 2021.09/12 and later to stop working:

  • VCX device firmware has not been updated to version V1.9.0.0 or higher.
  • The device is an illegal clone, and the firmware cannot be upgraded.
  • The VCX device does not have valid BENZ authorization.
Result:
  • If these conditions are not met, the XENTRY system will display an invalid serial number (e.g., 00000000), and the VCI device will be unavailable.
