This command can only be sent from the administrator number. To add a number to the list,

the administrator must send:

ADMIN ADDN 0831234567

The GSM Commander will reply with a confirmation message.

6.3.6. Remove a Number from the list*

This command can only be sent from the administrator number. To remove a number

(+27831234567) from the list, the administrator must send:

ADMIN REMN 0831234567

The GSM Commander will reply with a confirmation message.

*Please Note: The value predefined by the user via the software under the “Numbers Tab” (as

illustrated below), will determine how many numbers are able to be added and removed by

means of SMS.

7. TIMED OPERATIONS

The GSM Commander supports time constraints, which can be setup for any statement. Time

constraints will prevent a statement from triggering outside of the preselected times and days

of the week. The GSM Commander can also be configured to trigger a statement at a certain

time on a certain date or group of days.

The current time and date can be set in one of two ways, either by SMS or by clicking on the

tab “Set to PC time” in the software interface under the “Status Tab”.

By means of SMS you would send a special SMS message to the GSM Commander,

containing the text: “SETTIME”. The cellular network supplies the time and date with any

message that is sent, and the GSM Commander sets its own time according to this.

Please Note: The GSM Commander will lose its time if power is removed, and no battery

backup is used. Upon power-up, if any statement has a time constraint enabled, the GSM

Commander will automatically send a message to the first number in the list, requesting a

“SETTIME” reply so that it can set its time.

The GSM Commander will not allow any time constrained statement to trigger if the time has

not yet been set.

8. PREPAID AIRTIME VOUCHER LOADING

If using a prepaid SIM card, it is recommended that prepaid airtime be topped up via an ATM

or via your bank's Internet banking portal. If your network or bank does not support this, you

can purchase a normal airtime voucher and remotely send the voucher number to the GSM

Commander, which will in turn send the voucher number to the network to top up the airtime.
