DAYLIGHT SAVINGS TIME ADJUSTMENT DST
If the GSM module is being installed in a time zone that allows for daylight savings time then the automatic DST adjustment feature
can be enabled or disabled. By default this feature is disabled, set to 00. The following command can be used to enable or disable
this feature.
1111DSTnn Enable/disable the daylight savings time feature, where nn = 00 (disabled) or 01 (enabled).
1111DSTnn? As above and also send a conrmation text back to the sender.
1111DST? Query the status of the daylight savings time feature stored in the GSM module.
IMPORTANT NOTE: IT WILL BE NECESSARY TO REBOOT THE POWER TO THE GSM MODULE USING THE PROGRAMMING
COMMAND 1111RBT AFTER ANY TIME ZONE ADJUSTMENTS HAVE BEEN MADE. THIS IS SO THAT THE NEW CLOCK TIME
AND DATE SETTINGS WILL BE RECOGNISED AND TAKE EFFECT.
SEND GLOBAL ANNOUNCEMENT FEATURE SGA
It is possible to send out a global announcement text message to all the call button numbers stored (primary and divert numbers)
in the GSM module. The message can be up to 150 characters in length max. The feature is particularly useful if an urgent message
needs to be sent out to all users that use the GSM intercom in a single text. The following text message can be used, remembering to
include both the “ before and after the message, also if the message requires spaces between words then replace the space with a >.
1111SGA”text” Send global text message to stored call button numbers (inc. primary and divert numbers), where text
= message up to 150 characters max.
BUTTON OFFSET CONFIGURATION BOF
As mentioned previously on page 7 the 4G GSM module incorporates a button oset programming feature that allows the onboard
buttons on the GSM intercom module and any accompanying Art.404x button module(s) with the IDC connector to be congured
in such a way that the call button numbers read in ascending order from the bottom call button on the button module up (also refer
to the call button conguration tables on pages 7 and 8).
The button oset conguration feature will only be applicable for GSM audio systems that include the 1 and 2 button GSM module
and that have a total of 6, 7, 11, 12, 16, 17, 21, 22, 26, 27, 31, 32, 36 and 37 call buttons. For GSM systems that include 40 - 50 call
buttons the button modules Art.4842 .. Art.4845 should be used and would have to be manually wired to the GSM module.
By default this feature is disabled (i.e. button oset = 00). The following command 1111BOFnn is used where nn is either 00
(default) or a value between 81 - 87, see oset value table below, that identies GSM module's call button conguration and
the Art.4045 IDC button module(s) button oset. The table also shows the required button conguration jumper position for the
Art.4045 IDC button module(s), also refer to the examples shown in the call button conguration tables on pages 7 and 8.

The following button oset commands can be used to set (enable) the button oset value required and also conrm the button
oset value currently stored in the GSM module.
