iM1000-Data Modem
mounted on a plastic dashboard, it is recommended that the mounting
screws be located so they penetrate the supporting metal frame of the
dashboard.
Antenna Mounting
The best location for mounting the antenna is in the center of a large, flat,
conductive surface. In almost all vehicles, these requirements are best
satisfied by mounting the antenna at the center of the roof. Some vehicles
have a large trunk lid that provides a good antenna location. If the trunk lid
is used, connect grounding straps between the trunk lid and vehicle chassis
to ensure the trunk lid is at chassis ground.
Three types of antennas can be used:
1. RAF4136AMM - Magnetic Antenna
2. FAD5524A - Mobile Window Antenna
3. HAF9067A - Mobile Roof Mount Antenna
Make sure that you refer to the antenna installation instructions according to
the kit number.
DC Power Cable Installation
The iM1000 must be operated only in negative ground electrical systems.
Reverse polarity does not damage the iM1000; however, the iM1000
protection circuits cause the cable fuse to blow. Check the ground polarity
before you begin installation.
The DC power cable (FKN4878A) is long enough for installation in most
vehicles. Begin the power cable installation in the following manner.
1. Determine a routing plan for the power cable with reference to where
the iM1000 is to be mounted.
2. Locate the nearest available chassis ground mounting point and
shorten the black lead to remove excess cable length.
3. Locate the fuse holder as close as possible to the battery and away
from any hot component. Mount the fuse holder using the provided
mounting hole and dress the wires as required. Connect the fuse
holder red adapter lead plus to the mating receptacle on the red lead of
the power cable (see Figure 3).
4. Connect the black lead of the power cable directly to the chassis
ground.
5. Connect the power cable’s red lead from the fuse holder to the
positive (+) battery terminal. Make sure that the adapter cable is
connected to the red lead of the main power cable.
6. Place fuse into the in-line fuse holder (see figure 3).
