Hello Baggins,
first of all the Answer about the question how to update MxBus Modules
First, update the camera firmware.
After the reboot, you need to manually update each MxBus module. This is not a separate download. The update is embedded in the camera firmware but must be triggered manually via the camera’s Admin dialog.
A detailed how-to guide is available here:
About your new “Connection Issue”
Possible Cause: Cable, Connection, or Power Issue
Please follow these steps to diagnose the problem:
- Check the MxBus 2-wire connection
Inspect the cabling between the Door Station and the BellRFID module. Ensure the cable is intact, the connectors are properly seated, and there is no corrosion. - Inspect the RJ45 connector to the camera
Verify that the Ethernet connector is clean, corrosion-free, and securely plugged into the camera. - Check the camera’s power supply
- How is the camera powered—via PoE or a MOBOTIX power adapter?
- Has the PoE class changed recently?
- Have you added any new PoE-powered devices to the switch that might affect power availability?
- Review the system log
Look for older error messages indicating a “lost connection” or similar issues. - Power cycle the camera
What happens if you disconnect the camera from power and reconnect it? Does the issue persist after reboot? - Check the Camera System time!
