Multi-LED for status display
The sensor software is updated, if necessary, after
being connected. The status LED of the Access Con-
trol glows blue throughout the entire update process
and also flashes purple while the sensor itself is being
updated.
In addition, the status LED of the CMC III Processing
Unit flashes white and a corresponding message ap-
pears on the website.
Note:
No settings can be modified as long as the
update process is running.
The update of the sensor is complete when the follow-
ing conditions have been fulfilled:
1. The LEDs on the bus connection of the sensor light
green.
2. The multi-LED of the sensor behind the front panel
flashes blue and also green, yellow or red depend-
ing on the status of the sensor.
Further components are connected as a daisy chain.
