(to show the variables of the control unit)

Explanation:
factory.keys <2401 bytes> – factory keys (for control unit)
ethaddr=00:06:8e:3f:01:0a – serial number of the control unit
(or ethernet address)
client.keys <2797 bytes> – client keys
Key handling
To guarantee a high security in the communication between the
control unit (LCU) and ARX Server, two different types of keys are
used: factory keys and client keys.
The factory keys are already stored in the control unit at delivery.
They are unique for each control unit.
When the control unit establish contact with the ARX Server and
is approved the control unit is added to the ARX installation and is
given new keys – client keys.
When the control unit has been given these client keys it is locked
to a specific ARX server, the one allocating the keys.
