Satellite Data Modem (SDM) Installation
Trailer Swing Area
Trailer Swing Area
• DO NOT position the mount in the rear center of the vehicle. The corner of the trailer could
hit the SDM when the vehicle turns sharply.
• When positioning the SDM on the mount, protect the SDM connector by turning the
antenna so it faces the side and NOT the back of the trailer.
• Make sure that when the “fifth wheel” of a vehicle is fully forward, the trailer clears the
SDM when executing sharp turns or going up ramps.
• If the vehicle will be hauling refrigerated trailers, make sure that the refrigeration unit still
clears the SDM when the driver turns sharply or drives up ramps.
Installing the SDM Cable
• Connects SDM to MAS.
Connecting the SDM Cable
1.
Install the SDM cable on the SDM connector and hand-tighten.
Caution
If the cable does not easily connect to the SDM cable connector, check the part
number of the cable to make sure you are using the SDM cable. The SDM cable is
keyed to avoid an incorrect cable with a similar connector type from being attached.
