5InstallingtheLMU
TheinstallationoftheLMUanditsantennascanhaveamajorimpactontheLMU’sperformance.Itisrecommended
thatinstallersbefamiliarwiththeinstallationofGPSandcellulardevicesandarecomfortableinavehicle
environment.
5.1PreparingforInstallation
BesureyouhavereceivedalltheLMUcomponentsyouneed.Thismustinclude:
TheLMUtobeinstalled
Apowerharness
GPSAntenna(forexternaldevices)
CommAntenna(forexternaldevices)
OptionalComponents:
Inputandoutputcables
Relays
LMUperipherals(i.e.Serialadapter,jPOD,TetheredLocator)
Hostserialdevices(e.g.PDAs,laptops,otherserialdevices)
5.2PlanTheInstallation
VerifyPower,GroundandIgnition.Besuretocheckeachsource(power,groundandignition)toensurethat
thepropersignalingexists.Thisistypicallyaccomplishedwithamultimeter.
Beforedrillinganyholesorrunninganywires,decidewhereeachhardwarecomponentwillbelocated(LMU,
antennas,peripherals,etc.).BesurethatthecablestotheLMUarenotbentorconstrictedinanyway.Also
makesurethattheLMUiskeptfreefromdirectexposuretotheelements(sun,heat,rain,moistureetc...).
BeadvisedthataninstallationthatviolatestheenvironmentalspecificationsoftheLMUwillvoidthe
warranty.
Thebestwaytoensureatroublefreeinstallationistoconsideryouroptionsandmakesomedecisionsbefore
youstart.TakealookatthevehicleanddeterminehowtobestinstalltheLMUforthefollowingpurposes:
Accuratedatagatheringandsimulationofhowcustomersactuallyuseyoursolution
OngoingmonitoringandmaintenanceofLMUequipment
Accidentalorintentionalalterationoftheequipmentorcableconnections
ThefollowingsectionscoversomeoftheissuestoconsiderwhenplanningyourLMUinstallation.
