1.1. Connection and Communication
Step 1:
Unscrew the front panel of the enclosure and remove the board from the
enclosure. The board should slide out easily without excessive force needing to
be applied.
Fig. 1.2 –SIM card holders
Slide open the primary SIM cardholder labelled “PRI” (see Fig. 1.2) and insert the
SIM card (ensure that the SIM card is not PIN protected). Lock the SIM card in
place once inserted.
Step 2:
Place the board on a non-conductive surface (e.g. A wooden table or a book).
Connect the 12V and ground terminals to a suitable power supply (at least
12V/1A). You should see the LED light up red and then flash green quickly,
indicating that power is connected and the unit is operating normally. After
approximately 10 seconds (network dependant) the LED should flash green
slowly (1 second intervals) indicating that the device has successfully established
communication with the cellular network.

Step 3:
Ensure that there is sufficient Air Time loaded on the SIM card.
Add your cell phone as an “Authorised Number.” To do this, send the command
“admin” followed by a space, followed by your cell phone number with the
country code (27 for SA) at the beginning of the number. E.g. To add the cell
phone number 0826452344, the user will send:
admin 27826452344
You will receive a response from the GSM Communicator stating:
“You have been successfully added as an Authorised User on this device.”
You may now change other parameters on the device and all SMS alerts will be
sent to this cell number.
IMPORTANT: Please take care to ensure that the correct number is sent
using the correct format. An error may result in the user being "locked
out", which can only be reset using the Sentry USB dongle together with
the Sentry GSM PC application.
Step 4:
If you wish SMS alerts to be sent to a second destination simultaneously, you
may add a second number in the same format as above by sending the following
SMS to the device from the authorised cell phone used in step 3:
Report Destination 1: **13*number E.g. **13*27823259021
Up to 5 report destinations may be set, please see complete user manual for
further details if required.

Step 5:
You are now in a position to customise the input ports. As default, both input
ports will trigger if a high pulse (12V) is received for 1 second or longer. Please
consult the complete user manual if further customisations are required. To
customise the SMS text that each input will send, issue the following commands
to the device via SMS:
Input 1: **36*text E.g. **36*ALARM ACTIVATED
Input 2: **37*text E.g. **37*PANIC ACTIVATED
Both input texts can be set in a single SMS. E.g:
**36*ALARM ACTIVATED**37*PANIC ACTIVATED
Do notplace a space between individual commands.
Step 6:
The output ports (relays) may be set up in a similar manner. Firstly, set the
desired mode of the relay i.e. Latch (0), pulse (1) or toggle (2). The mode can be
set by sending the following SMS text to the device:
Relay 1: **100*mode E.g. **100*1
Relay 2: **101*mode E.g. **101*0
The device can be programmed to accept specific text commands (up to 20
characters) to activate each relay. To set the “ON” text, the device must be sent
the following SMS command (not case sensitive):
Relay 1: **30*text E.g. **30*OPEN GATE
Relay 2: **32*text E.g. **32*RESET ALARM
If relay mode is set to latch or toggle mode then the relay must be deactivated
by an “OFF” command (up to 20 characters), which can be customised by
sending the following command:
Relay 1: **31*text E.g. **31*LIGHT OFF
Relay 2: **33*text E.g. **33*SPRINKLER OFF

If the relay is set to pulse mode, it will automatically deactivate after a pre-
determined time duration. The time duration is set in increments of 10ms.
Therefore, if you wish the relay to activate for 1 second, you will set the “ON”
time to 1s ÷ 10ms = 100. If a 2 second duration is required, you will set it to 200,
etc. The time duration for each relay may be set by sending the following SMS
command to the device:
Relay 1: **104*time E.g. **104*150
Relay 2: **105*time E.g. **105*200
As with the inputs, multiple commands may be strung together in one SMS (max.
160 characters) E.g:
**100*1**30*OPEN GATE**104*200
The command above will set relay 1 to pulse for 2 seconds when the text “Open
Gate” is received from an authorised user.
Step 7:
The device may be programmed to send an automatic “report” SMS periodically
to the report destinations. It is advisable to make use of this feature (at least
weekly) to ensure that the account remains active on the cellular network. The
interval between report messages is set in increments of 1 minute. For example,
if you wish the device to send one message per week, the parameter must be set
to 1min x 60 x 24hrs x 7days = 10080. The command to set this is as follows:
**114*time E.g. **114*10080
Step 8:
The device can be set to send an alert if the battery voltage drops low. The
voltage can be set in 1V increments (**49) and the alert function must be enabled
(**48) at the same time. To set the device to send a low voltage alert, the
following SMS command may be sent to the device:
**48*1**49*voltage E.g. **48*1**49*10

Adding/Deleting Regular Users
Regular users may access the outputs remotely via SMS or missed call (relay 1),
but may not change any settings on the device. Only an Authorised User (step 3)
may add or delete Regular Users.
Add User: Type the word "ADDUSER" followed by a space character, followed
by the cell number that you wish to add in the same format (with country code) as
step 3.
E.g. ADDUSER 27823259021
Delete User: Type the word "DELUSER" followed by a space character,
followed by the cell number that you wish to delete in the standard format.
E.g. DELUSER 27823259021
Check User: Type the word "CHKUSER" followed by a space character,
followed by the stored cell number that you wish to verify in the standard format.
A response will be sent back indicating whether the number is currently stored on
the device.
E.g. CHKUSER 27823259021

Please Note:
This document highlights the basic and most popular commands involved in
setting up the device. For a full list of settings that can be manipulated remotely,
please see the GSM Communicator SMS Setup Commands document
included in the web download. Alternatively, the user can make use of the free
and easy-to-use Sentry GSM Management Platform software and dongle to set
up the unit via USB.
