Parameter X251 was entered in software 8r56. In this parameter the logical number (from the keypad point of view)
with which the keypad is to start a connection should be entered. This number is recalculated as if it had been
entered manually.
It is necessary to make sure that the configuration of system does not cause conflicts between the lock control
and parameter X251 – i.e. the event from AUX button should not be assigned to the lock opening.
Note! The parameter X251 for the common satellite must be the same in all PBXes that support it. If the
parameter is inconsistent (different depending on the PBX), the function may work in a ‘random’ way
Note! This parameter should not be set as global, it should be entered for specific devices
Note! Default settings of KDC1905M system are such that when AUX button is pressed, the lock is always
opened. When using AUX button call function, all system reactions related to AUX button on the keyboard must be
blocked.
Example:
If the keyboard at which AUX button is to be assigned to ringing is located on slot 2
(serial number entered in par. 2001), the lock control must be blocked locally in
parameter 1364.
