3. Fit the link across J1 and power up the receiver. If the channel compartment
pertaining to the selected channel is not blank (has at least one button, whether it
is mastered or not, associated with the channel), then the receiver will enter bulk
demaster mode. If the entire memory is selected for demastering, then at least one
button must be learnt into memory (on any channel) to enter bulk demaster mode.
4.
After the firmware version number has flashed on the Status LED, the LED will begin
to flash quickly to signal that the receiver has entered bulk demaster mode. If the
LED does not flash quickly, then the system is not in bulk demaster mode, either
because jumper J1 was not linked correctly before power-up, or because there are no
buttons learnt into memory (or associated with the channel selected by the channel
jumpers).
5.
To confirm the bulk demastering operation, jumper J1 must be removed. If the
receiver is powered down before the jumper is removed, the bulk demastering
operation is not executed. This is useful if the mode is entered accidently and no
buttons must actually be demastered.
In step 3 above, it is noted that the system will only enter bulk demaster mode if at least
one button is learnt into the system, and associated with the channel specified by the
channel jumpers. If there is no button in the relevant channel compartment, then the
receiver transitions into Autolearn mode for the selected channel. Refer to the Autolearn
section for more information.
4.4. Autolearn Mode
Multichannel receivers support the ability to map buttons to channels during the
Autolearn process. Part of the Autolearn setup procedure requires the establishment
of an association table. This table will be used for all buttons learned into memory
during the actual Autolearn procedure. Autolearn mode is also limited to a maximum
of 7 days before it times out. This prevents a user from accidentally leaving the system
in Autolearn on an indefinite basis. There are security risks linked with a system that
is placed in Autolearn mode. The 7-day timeout will minimise these risks while still
providing the convenience of auto-learning buttons.
1.
Channel compartments configured for Autolearn must be blank. In other words,
the entire Tx Memory needn't be blank to enter Autolearn, only the relevant
compartments. As a result, it is possible to enter Autolearn mode multiple times; so
long as the channels configured for the Autolearn session are blank.
2. Fit the desired channel links for the channel that is intended for auto-learning. It
is possible to omit channel links and enter Autolearn for channel 1, but only if the
channel is blank. In the case of single-channel receivers, this step can be omitted
since there are no channel jumpers. Single-channel receivers always enter Autolearn
mode for channel 1.
3. Fit the link across J1 and power up the receiver. One of two possible situations will
result:
a. The selected channel (set via the channel jumpers) is blank. In this case, the
system enters the Autolearn Commissioning procedure. The receiver remains in
this state while the link on J1 remains fitted. While in the commissioning state, the
LED on the receiver remains on. Entry to the commissioning state is also signalled
by a long beep from the buzzer. Continue to step four.
b. The selected channel (set via the channel jumpers) is not blank, or no channel
has been selected (no channel links fitted). In this case the system enters
bulk demaster mode. Refer to the section with the title, Bulk Demastering, for
more information on the behaviour of the system in this mode.
