7. Installation Verification
In many cases it is desirable to verify that an installed LMU-3040™ is working properly. That is,
installers should verify that the GPS and communications functions of the LMU-3040™ are working
properly before departing the installation site. In more robust cases, some key configuration settings
such as the Inbound Address and URL should also be verified.
Note that these processes are all based on issuing AT Commands to the LMU-3040™. It is expected
that installers will have access to a serial port expansion cable and a laptop or PDA capable of a
terminal connection. Alternatively, an SMS message can be sent to an LMU-3040™ to obtain its
current status.
7.1 Comm Verification
Installers should first verify that the LMU-3040™ has been acquired and has registered to the
wireless network.
Comm may be verified using an AT Command:
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.
