System Reference Guide F01U087835 | 02 | 2008.102.8 Configure the ITS-DX4020-G Communicator2.8.1 Configure the Control Panel for Cellular CommunicationYou must enabled GSM dialing, and set the format used and the destination IP address andport number or phone number. You can also configure anti-replay and other parameters. Todo so:1. Enable GSM dialing using Expert Programming Item 202.2. For the primary and backup destinations, configure the control panel options as desired.Refer to Table 2.7, Page 25 for an example of a typical configuration and thecorresponding Expert Programming Items.Table 2.7 Example Configuration for Cellular Communications2.8.2 Configure the ITS-DX4020-GEnsure that the configuration jumper is installed on the CONFIG MODE (J200) pins.Refer to Section 2.2.5 Install the ITS-DX4020-G Communicator and Antenna, page 15 for properinstallation.1. Observe the LEDs to check for signal strength. Refer to Table 2.8, Page 25. Refer toFigure 9.1, Page 62 for LED locations.Table 2.8 ITS-DX4020-G Signal Strength LEDs2. Call the central monitoring station (CMS) and provide the account number (may beknown as NNC number at the CMS), and control panel polling rate.3. Observe the BUS LED. The LED stays on steady when the communicator has permissionto be configured. Refer to Figure 9.1, Page 62 for LED locations. Refer to row 2 inTable 2.9, Page 26.4. Observe the SS1 LED to confirm the ITS-DX4020-G is registered and has sufficient signalstrength to configure it by SMS. The SS1 LED must be On to continue. Refer toFigure 9.1, Page 62 for LED locations. Refer to Table 2.8, Page 25 for the LED states.5. Use the SMS configuration template to send the SMS to the installed SIM card phonenumber.
