Lancer 3W Installation Guide

Example of permanently mounted serial cable
•
Allows you to identify cable issues that could affect modem operation, for example,
bends or kinks in the cable or obstructions in the vehicle that could affect routing.
Here are guidelines for checking your cable layout:
•
Ensure the distance between the Lancer 3W modem and the vehicle power source is
not longer than the length of the routed power cable. The power cable is 15 feet long.
•
Ensure the distance between the Lancer 3W modem and the computer is not longer
than the length of the routed serial cable. The serial cable is 15 feet long.
•
Ensure the routed antenna cable is minimized as much as possible and the distance
between the antenna and the Lancer 3W modem is not longer that the cable length.
•
Select a cable routing free of hazards such as excessive heat, possible screw
punctures or a routing that requires you to pinch or kink the cable when installing it.
•
Secure each cable in place when possible. A cable that moves eventually frays and
breaks.
•
Document cable routing for future reference and keep it with the vehicle records.
•
Ensure cables are at least 8 inches (20.3 centimeters) away from any microprocessor
controlled electronic equipment.
3.4.1 Serial Cable Routing
Serial cable routing is the most important factor to
assure a trouble-free operation. The majority of
problems occur because of serial cable failure. The
serial cable should be as stable as possible. This
means it should receive little or no movement and
have very few or no bends and kinks in it. If
possible, you should try to find a permanent place
for the serial cable and mount it securely.

Mounting and Connecting Equipment
After locating and laying out cables, you’re ready to
mount equipment and connect wires.
Warning
