5.4InstallationVerification
InmanycasesitisdesirabletoverifythataninstalledLMU42x0™isworkingproperly.Thatis,installers
shouldverifythattheGPSandcommunicationsfunctionsoftheLMU42x0™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42x0™.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42x0™toobtainitscurrentstatus.
5.4.1CommVerification
InstallersshouldfirstverifythattheLMU42x0™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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.
