3. Connection
In order to operate properly, the device must be equipped with a valid SIM card (GPRS data type) and
the external antenna must be connected to the antenna connector. Use the supplied antenna or any
other GSM antenna that suites the needs for installation. The SIM card should be inserted to the card
holder “door” (the moving part of card holder), as shown on picture. The Door must be pushed toward
the PCB until completely “closed”, i.e. the two parts of card holder are overlapping, and after that the
card holder should be LOCKED, by pulling the holder ”door” toward the terminals (as marked on the
holder). The locking of card holder gives a click sound. If the card was not placed properly as it should
be, the card holder door can not be locked and turning the PCB in horizontal position with card holder
toward the ground will cause the holder to open. In this case, the device will not operate properly, and
may cause the damaging of SIM card. Please be sure that the SIM card is placed properly before
powering up the device.
Warning: The SIM card should never be removed or added while the device is powered up.
3.1. Power supply
SC-GPRS communicators can be powered from USB connection for programming only (downloading of
settings). For normal operation required the external power (connected to terminals +12V and COM).
The device will be functional with any power voltage between 9 and 30 V DC is applied to the terminals.
3.2. Emulated phone line
The TIP and RING terminals of the SC-GPRS device provides an emulated phone line. Connect these
terminals where the PSTN (regular phone line) is supposed to be connected to the device that will use
this communicator. In case of connecting to alarm panel, use the INCOMMING LINE terminals, (usually
marked with TIP/RING or T/R, or Ti/Ri...).
3.3. Trigger inputs
There are 2 CONTACT inputs on device, marked as Z1 and Z2. These inputs are used to trigger to send a
specified Contact ID code to the monitoring station. These inputs are triggered when connected to the
COM, i.e. to the supply negative line. When connecting the device to an alarm panel, if the power is
supplied from alarm panel (connected to its AUX terminals) these inputs can be directly connected to
PGM outputs of alarm panel, that are “open collector” type, since when activated, these outputs
provide a shortcut to the panel ground. With such connection, no other wiring is required. If the PGM is
RELAY type (two connection points), than one pole of the output relay must be connected to the same
place with the communicator COM terminal, and the other to Z1 or Z2, in balance with programming.

4. Configuration of device
Connect the device with USB cable to a windows PC (Compatibility: Windows 7, 8.1, and 10), and a new
drive will be installed. When connected to that machine for first time, the driver will be installed first,
then the new drive will be found. This drive is the flash memory of SC-GPRS device, and contains the
software and this manual. You can run the software from device, or copy it to your PC and run it from
there. When the device is powered through terminals, the USB cable can be plugged or unplugged at
any time, it will not affect the device. The windows machine might require a proper closing of USB
connection before unplugging the cable.
4.1. Setup program connection
If the device is password protected or a wrong type of device is connected on USB port, the PASSWORD
field is displayed. If a wrong password is entered, the software will display the status fields only Settings
are not displayed and can not be changed. This mechanism prevents unauthorized access to device
settings.
As the software successfully connects to the device, it reads out the device and shows the status, device
version and actual settings in device (marked red on following picture):
In case that software does not show a “connected” status or the firmware version, the USB connection
was not made properly. Please select a different USB port check the USB cable. If the problem persist,
the device USB driver might be in conflict with some other driver in windows, restart the windows or try
the connection on another machine.

4.2. Moving data between the PC and the device
Reading out data from the device happens automatically as soon as connection is established. Settings
can be saved to PC or loaded from PC file. These icons are used to handle the settings data:
(File_reading / File_saving / Download to device )
IMPORTANT NOTICE: if a new settings file is loaded or ANY setting is modified on software screen, all
data needs to be downloaded onto the device. You can make all required changes in software, and then
download data. Changes that were not downloaded will be terminated when the software is closed or
the connection is cut (cable unplugged).
4.3. Device code lock (protection)
The device can be locked with a security code. By default, there is no code but once entered, the code
will be required for each connection. After connecting, the new code can be entered with the icon:
After connecting via USB, if the device was set with a code, the software requests to enter the
device code. If you cancel the code entry, the software will display only the status and no settings can be
red or edited. After closing re-starting the software, the code entry box is displayed again. Only after the
right code was entered, the software will be fully functional, presenting the whole window with all
settings displayed and editable.
WARNING: If the password is lost or forgotten, only way to access to device setting is with FACTORY
DEFAULT. For that procedure, the device must be sent to appropriate service
4.4. Device Status
Status of the SIM card, network and connection to GPRS ( APN) are presented instantly, at the “Module
state “ field. As soon as the Monitoring station parameters are entered, the device will try to send a
“check in” signal, and present the status (OK or Failed) for sending to that that Monitoring station (MS1
and MS2). Also the status of two inputs is displayed in same field.
This part is ALWAYS VISIBLE, even when the device is protected with code lock. These are the possible
values of the fields in the status view:

SC-GPRS Alarm Monitoring Communicator v1.3 10 EN
5. Operating logic for alarm reporting
1. Reporting from alarm panel starts with a „hook off” of the line state. This means that the alarm panel
has „picked up” the phone line and is checking for it’s presence. If communicator finds everything all
right and is able to accept the signal, it will provide a regular „line free” free signal. If something is wrong
and communicator is not able to forward the information, it will give a „line busy „ signal.
Typically, „busy” signal” means that a SIM card is missing or bad, PIN code is wrong, or none of receivers
can be reached.
2. Alarm panel dials the phone number and waits for the ”handshake” signal from receiver. If the dialed
phone number fits to a value in field „Dialed number by alarm system” (for MS1 OR MS2, if both are
available), or if that field is BLANK, the communicator will provide the „handshake” signal and the alarm
panel will transmit the CID message.
3. When the CID code is received, the communicator will send the report to the appropriate MS,
selected with the phone number dialed by alarm system. If the „Dialed number by alarm system” field is
blank, then the report will be sent to MS1, as long as it is available- only when MS1 is not available (
receiver can not be reached), the message is sent to MS2.
4. The „account number”, i.e object identifier in the message that is sent to receiver will differ from the
one received from alarm panel, if the „replace panel identifier” field is selected „yes”. In that case, the
Identifier will be changed to the value set in „object identifier”.
5. When the report is sent to receiver, it forwards it to monitoring software and it returns the
„acknowledge”, a receipt for the message. The reciver sends the „acknowledge” to the communicator,
and it transmits the „acknowledge” tone to the alarm panel. Since the response time of the alarm panel
for acknowledge is short, the alarm panel will repeat the CID message before the acknowledge is
received from monitoring station. The device waits the end of repeated message and transmits the
acknowledge.
6. After receiving the acknowledge, the alarm panel starts transmitting the next CID code if there are
more reports to be sent, and the procedure is repeated from point

SC-GPRS Alarm Monitoring Communicator v1.3 11 EN
6. Parameters setting by SMS messages
Informations about the device and changes of the most important settings can be sent through SMS.
The format of the message should be:
parameter=value*
More commands can be sent in one message, but every command must finish with character *
(therefore, the message also must finish with this character)
parameter1=value1*parameter2=value2*...
For example: APN=internet*IP1=82.65.128.185*
Here is the list of parameters that can be changed with explanation for the name:
INFOSMS: Phone number to which the incoming messages will be forwarded
APN: apn
USR: username (for the APN)
PWD: password ( for the APN)
IP1: IP adress of the MS1 receiver
PORT1: receiving port of the MS1 receiver
IP2: IP adress of the MS2 receiver
PORT2: receiving port of the MS2 receiver
The RESET command is special, it can not be combined with other commands, therefore the message for
reset must be like this:
RESET*
You can also request the status information from the device, with following command:
?*
The device will reply with a SMS message that contains the information, in following format:
SIGNAL: 21
GPRS: OK
MS1: OK
MS2: ERROR
( These values are EXAMPLE)

SC-GPRS Alarm Monitoring Communicator v1.3 12 EN
7. LED indicators
The following LED indicators show the functional status of the communicator.
In case of error RED TROUBLE LED is continuously ON, while GREEN LED is flashing according to the code
of the error reason. In “Idle state”, when everything is „Normal” only the GSM STATUS LED will be ON. If
the GSM Signal is below the requested level, this LED will blink. If some fault is valid, red TROUBLE will lit
continuously, while green LED shows the cause of the fault with blinks.
