Installation
Installing the SU-M-900 Unit
The SU-M-900 unit must be installed securely in the vehicle. Four screws
are needed to mount the SU-M-900 to either a sheet metal or a wooden
surface.
The position of the SU-M-900 unit must enable it to be easily connected to
the PC, the omni antenna and the power supply. See the connection
diagram (Figure 2-1 on page 2-6) for guidelines regarding relative placement
and how best to connect the units.
To install the SU-M-900:
1.
Place the unit against the surface to which it is to be mounted. Mark
the screw placement using four of the mounting holes in the unit as
guides.
2.
Drill four holes in the surface using the marks you made.
3.
Clear all paint, dirt and oil away from the area around the holes.
4.
If the SU-M-900 unit is being mounted directly to the car chassis,
sheet metal screws should be used. Star washers must be used to
provide a ground connection through the screw to the metal car body,
Or
If the SU-M-900 is being mounted on a non-conductive surface, such
as wood, suitable ¾" wood screws should be used.
5.
In addition to the star washers a ground strap with a terminal lug is
needed for connecting the SU-M-900 ground screw, which is located on
the front panel, to another grounding point in the car body.
6.
Affix the unit firmly in place with the appropriate screws.
