AO1 SET TO MODE 04, ‘CALL ACTIVATED (TIMED)’
Similar to mode 00, however, when set to mode 04 auxiliary output AO1 will activate when the call begins and deactivate when the
auxiliary AO1 time expires, see
Fig.23
.
The auxiliary output AO1 time can be set using the SMS programming code
1111A1Tnn?
(where nn = time in seconds, also refer to
programming notes on page 35) or setup by using the GSMSK PC programming software.

AO1 SET TO MODE 05, ‘ENABLE/DISABLE DIAL TO OPEN NUMBERS’
When the auxiliary output AO1 mode is set to 05 the dial to open numbers will only activate the GSM relay when a common and
normally open (CO/NO) switch connected across terminals g & AO1, as shown in
Fig.24
, is open circuit. When the switch is closed
and terminals g & AO1 are short together this will disable the dial to open numbers.

IMPORTANT NOTE: When auxiliary output AO1 is set to a particular mode (00 - 05) it cannot be used as an input/output for
anything else.
