This chapter describes how to upgrade communication hubs and locks/sensors with a new firmware. The upgrade procedure will be executed only for the selected communication hub or lock/sensor, depending on the content of the firmware. The firmware file only contains firmware applicable to either a communication hub or a lock/sensor.
Note: Always upgrade the communication hub before upgrading the locks/sensors. The reason is
that communication hubs should always support older lock/sensor firmware but the oppo- site
may not always be possible.
Note: When upgrading AH30 communication hubs to the latest firmware, when using the DIP switches
for EAC addressing, always check that the DIP switch is set to the correct EAC ad- dress. If
DIP 5 is active by mistake, an upgrade will result in the communication hub starting to use
another EAC address.
Note: When upgrading AH40 communication hubs to the latest firmware, Ethernet can be used to
download the new firmware, provided that the AH40 communication hub IP address and other
network settings has been correctly set up.
