ATIC
Depending on the wireless network being used something similar to what is shown below will be displayed. It
is important to verify that 'Yes' values are displayed at the top for Data and Network registration and the
correct APN is displayed.
Radio Access : GSM
Network Reg. : Yes, Home
Data Reg. : Yes, Home
Connection : Yes
RSSI : -97 dBm
BER : 99
Channel : 737
Cell ID : 3441
Base Station ID : 40
Local Area Code : 31003
Network Code : 410
Country Code : 310
IMEI (Modem S/N): 351802055396182
IMSI (SIM ID) : 310410202524377
ICC-ID (SIM S/N): 89014102212025243778
Phone Number :
GPRS APN : ISP.CINGULAR
Maint. Server : maint.vehicle-location.com(216.177.93.246):20500
Inbound Server : (0.0.0.0):20500
Dual Comm : routing id=0, log cid=0, modem type=21, inbnd index=0
OK
If any of the responses return Not-Acquired or Not-Registered (and the APN is correct), the wireless network
operator should be contacted for further troubleshooting.
Please note that it may take several seconds (or longer) for the LMU-2600™ to communicate with the modem
and acquire the wireless network.
5.4.2 GPS Verification
The next step is to verify that the GPS receiver is seeing enough satellites to obtain a valid GPS position.
Again, installers have two choices on how to perform this verification. First, like the Comm Verification, there
is a GPS status LED (i.e., the one closest to the SMA connector). If this LED is solid, then the LMU has found
GPS service.
If the LED is not visible then GPS service may be verified using an AT Command:
AT$APP GPS?
The response should be similar to:
Lat=3304713, Lon=-11727730, Alt=0
Hdg=113 Spd=0 3D-RTIME HDOP=130 nSats=7
