5.7.3.2. Configuration
The access modules work with internal encryption. The key is stored in the DatafoxStudioIV but not
visible.
If no key is provided under "AES Key" (PHG only), the default key is used.
Caution:
The key must only be changed at a fully installed access control. If you changed the key
and forgot it, the modules must be sent in. Restoring the default key is subject to a
charge.
All door modules that are compiled in the reader table have to be available in the RS485 network in
order to guarantee that the code can be changed in all modules if a new setup with a different code
is loaded. If a door module from the list in the bus is missing, the key is not changed. The old setup
with the old key has to be reloaded; otherwise, after rebooting the device, it is not possible to com-
municate with the door modules until the right key is used again.
