To point your GoSafe device to a tracking server (Port 5078), send the following SMS commands from an authorized mobile number:
Step A: Set APN (Network Data)
Format: APN,password,APN_Name,User,Pass#
Example: APN,0000,internet,user,pass#
Example: APN,0000,internet,user,pass#
Step B: Set Server IP and Port
Format: IP,password,Server_IP,Port#
Example (Port 5078): IP,0000,193.193.165.165,5078#
Example (Port 5078): IP,0000,193.193.165.165,5078#
Step C: Set Reporting Interval
Format: INTERVAL,password,Moving,Static#
Example: INTERVAL,0000,30,3600# (30s when moving, 1hr when stopped)
Example: INTERVAL,0000,30,3600# (30s when moving, 1hr when stopped)
