Manual Datafox ZK-MasterIV
3.8.2 Configuration
The access modules of PHG with phg-crypt-protocol use an encryption in accordance with the Rijndael
/ AES-128 standard (AES - Advanced Encryption Standard). The code is set in the setup under access
after selecting the access series. The 1685 protocol of PHG is not supported by Datafox.
Figure 62: Communication key for the PHG-crypt protocol
The modules always work with encryption. If no code is entered, a not published standard code is used;
otherwise, the entered user code is used. Please use all the 16 byte of the code.
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 is missing in the bus, no change of the code takes place. The old setup with
the old code has to be reloaded; otherwise, after rebooting the device it is not possible to communicate
with the door modules until the right code is used again.
If a defective reader is replaced by a new reader that has not been used yet, the firmware recognizes this
automatically at the start and sets up the encryption. The reader can also be changed during operation,
the firmware automatically integrates it.
If you have forgotten the user code for a door module, there is no possibility to activate the readers. The
reset of the forgotten key at the reader can only be done by PHG.
