4.3 Installation Verification
In many cases it is desirable to verify that an installed LMU-303x™ is working properly. That is, installers
should verify that the GPS and communications functions of the LMU-303x™ 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-303x™. 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-303x™ to obtain its current status.
4.3.1 Comm Verification
Installers should first verify that the LMU-303x™ has been acquired and has registered to the wireless network.
This may be verified in one of two ways. First, installers may look at the LED. If this LED is solid, then the LMU
has registered to the network and established a data session.
If the LED is not visible, then 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.
