Commax DR-GSM Mini
The DR-GSM Mini must have a power supply that can handle up to 2A spikes from SMS and GPRS usage. It is therefore
recommended to connect to a battery or good power supply.
Please make sure that the SIM card in use does not have a security PIN number. This can be disabled by putting the Sim
card in a mobile phone and removing the PIN request.
The DR-GSM Mini is operational when the green and blue LEDs flash slowly.
SMS Programming
žAll SMS commands start with an asterisk ‘*’ followed by a 4 digit password eg. *2222 where 2222 is the default password
žAll commands are confirmed with a reply SMS to the person sending the message or to the status number (if set).
žAll commands must be sent in UPPERCASE
Resetting
Number Programming
Hold down both buttons and apply power, continue to hold the buttons for 5 seconds and the green and red LEDs will begin to
flash fast, release the buttons when the LEDs begin to flash slowly - the device password and system settings will be reset.
To additionally clear the number list hold down the buttons for a further 5 seconds while LEDs are flashing slowly and then
release.
Relay 1 and Relay 2 may be triggered by use of missed call. When a user’s number is added to the missed call list. Calling the
DR-GSM Mini from these numbers will optionally trigger relay 1, relay 2.
If Auto answer is selected the call will be answered alternatively the call is hung up (see next page for programming)

Voice Call (Intercom)
In the case of intercom if an input is triggered the DR-GSM Mini will perform a voice call instead of reporting the input to the
cloud.
More than one number can be programmed for the same input. Should the person not answer, or hangup, the second number
will be called. The numbers are called in order that they are added or in the order of the memory position (lowest first to
highest)
Once the call is answered no further numbers will be called.
Examples:
*2222 ADDN 27821231234,0,BC3D - Call this number when input 3 is triggered (3D), trigger relay2
*2222 ADDN 27821231234,0,2D - Call this number on input 2 (2D), no missed-call triggering
when this number missed-calls the DR-GSM Mini (A)
Delete a number: Clear All numbers
*2222 DELN 27821231234 *2222 CLRN
when this number calls the DR-GSM Mini (B) and autoanswer
the call. (C)
*2222 ADDN 27821231234,0,B - Trigger Relay2 when this number missed-calls the unit (B)
Note on calling multiple numbers:
*2222 ADDN 27821231234,0,A1D - Call this number when input 1 is triggered (1D), trigger relay1
*2222 ADDN 27821231234,0,A - Trigger Relay1 when this number missed-calls the unit (A)
Adding a number (Input SMS, Intercom Dialing, Missed Call)
*2222 ADDN 27821234123,[Z],[XXXXX]
27821231234
number calling the unit
SEE EXAMPLES BELOW
This is the telephone
IMPORTANT!
All numbers need to contain the international dialing code (27 for South Africa) without a leading + or 0 eg: 27821234567 is correct
[Z] is the memory position
use 0 to add to the
next available position
{ { {
[XXXXX] - These are the permission of the telephone number 1.
more than one permission can be used at a time
1 - Call this number when Input 1 is triggered
2 - Call this number when Input 2 is triggered
3 - Call this number when Input 3 is triggered
4 - Call this number when Input 4 is triggered
A - Trigger Relay 1 when this number calls the unit (missed call)
B - Trigger Relay 2 when this number calls the unit (missed call)
C - Auto Answer the call
D - Dial the number (intercom)
Output Tiggering (SMS)
*2222 SET[A]=[B]
[A] is 1,2,3 or 4 for inputs 1-4
Examples
Turn ON or Turn OFF
[B] is 1 for ON and 0 for OFF
*2222 SET2=1 This will turn on Relay 2
*2222 SET1=1 This will turn on Relay 1
*2222 SET4=0 This will turn o ffRelay 4
Each of the outputs may be turned ON, turned OFF, or pulsed. The format of the SMS is:
*2222 PUL2 This will pulse Relay 2
*2222 PUL4 This will pulse Relay 4
*2222 PUL[A]
[A] is 1,2,3 or 4 for inputs 1-4
Examples
*2222 PUL1 This will pulse Relay 1
Pulse Output Pulse Output during call
To trigger relay 1,2,3,4 press
1,2,3,4 respectively on your
phone keypad during the
phone call (intercom).

System commands
Relay Pulse Time:
*2222 PTIME [A] [B] [C] [D] - [A] [B] [C] [D] each is a two-digit number from 0-99 representing the pulse
time in seconds. If 0 is used it is 0.5seconds (default).
PLEASE NOTE THE SPACE IN BETWEEN [A] [B] [C] [D]
[A] is Relay 1 time [B] is Relay 2 time [C] is Relay 3 time [D] is Relay 4 time
Set hangup time:
*2222 HANG [A] - [A] is the hangup time in seconds default 25
Airtime retrieval
The airtime response will be sent to the number requesting it.
Example: *2222 PTIME 00 02 05 10 Relay1=0.5s Relay2=2seconds Relay3=5 seconds Relay4=10 seconds
*2222 NETW [XXXXX] - [XXXX] is the USSD command to retrieve airtime such as *136#
Example: *2222 NETW *136#
