6.2 Installation Verification
In many cases it is desirable to verify that an installed LMU0200G is working properly. That
is, installers should verify that the GPS and communications functions of the LMU0200G
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 SMS messages to the LMU0200G. It is
expected that installers will have access to an SMS capable handset.
6.2.1 Comm Verification
Installers should first verify that the LMU0200G 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
Comm LED (i.e., the one closest to the SMC antenna connector). 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 SMS Message of:
!RC
The LMU™ should send the follow SMS reponse:
-93 DA. 9+ 10.10.4.142 20510
M:O.. 207.71.209.248 20500
I:Osr 172.254.1.10 5557
O:Osr 172.254.1.10 20510
OK
Installers are looking for both the ‗D‘ and ‗A‖ in the first line. This indicates that the LMU
has registered to the data network and has successfully reported to an LM Direct server.
Please note that it may take several seconds for the LMU0200G respond.
