The 7720P programmer or the Web-Based Program is used to enter all central-station information. This is saved to the IPGSM-COM communicator panel memory. When the IPGSM-COM Communicator is installed at the site and connected to the Internet/ Intranet, it registers itself with the AlarmNet receiver. This eliminates the need for a PC at the remote site for programming. For most installations, the only required parameters are: Primary City ID (two digits) obtained from your monitoring station. Primary Central Station ID (two digits) obtained from your monitoring station. Primary Subscriber ID (four digits) obtained from your monitoring station. Communication Module's MAC ID, and MAC CRC number located on outside of box, and inside of the module. All of these parameters are assigned by the monitoring station.
