Purpose EasyGPRS communicator is a device of alarm signal transmission from centrals SatelCA6, SatelCA10 and ST-704 to the security monitoring station, using the GLab-crypto™ protocol. External view of the device is shown on figure 1. Figure 1.

SIM card installation. Connect the antenna to the SMA connector of the device (see figure 2). Figure 2. ATTENTION! Turning on the device without the GSM antenna causes the GSM module to malfunction. Note that the manufacturer’s warranty does not apply to the GSM module. Insert the SIM card into the device as shown on figure 3.
Connecting the device to SatelСА6, SatelСА10. The (typical) example of device connection is displayed in Appendix 1. Template recording. An automatic recording of the necessary for the device to work monitoring station administrator’s phone number is possible to the phone book of the SIM card. In order to do so you need to delete an entry named «GBGPRS001»...
The device outputs are of «open collector» type and are commutated to the common ground. The «LED» output is used to connect the LED indicating arm/disarm (see Appendix 1). The outputs can be used for remote management of various equipment, control of security panel operation or arming confirmation indicating LED management by the security monitoring station operator.
Mode 3 – indicating communication with the security monitoring station. This mode is used control the data transfer in the security protocol GLab-crypto. Yellow LED «3» indicates: An attempt to transmit data to the monitoring station and wait for connection is accompanied by fast blinking.
SMS command format Programming the settings. A text SMS with commands «*1XX*СYYY*» inside the message body is used to program the settings. List of commands is displayed in Table 5. Table 5. Command Example Note *0ХХ* *010* Frequency of sending the test message to the security monitoring station.
Appendix 1: Examples of the device connection. The examples of device connection to the central Satel CA6 (figure 5) and central Satel CA10 (figure 6) are displayed below. Figure 5. An example of the easyGPRS connection to the Satel CA6. Figure 6.
Appendix 2: The GRAPH server program usage. The server part of software is designed to receive and decrypt messages in GLab-crypto protocol and to register new transmission devices while giving them an encryption key (for protection against substitution). Decrypted messages in Shur-GARD ContactID format are forwarded to a COM port in an existing system or to the other IP address.

- «Notification line port» - a message about a key request by the object device is displayed through that port. «Set new encoding key» - a code phrase (no less than 8 symbols), based on which the program generates the encryption key. ...

Tab «Output interface» - here it is possible to set the output for received and decrypted messages to COM port of a computer or to an IP address. If the station software understands the Sur-GARD receiver on the СОМ port, a free program com0com (http://com0com.sourceforge.net) can be used to create a pair of virtual serial ports.
