2.3.2 Physical mounting
a)
Start by running all the cables (DC power, CAT5 Ethernet and
optional PC RS-232
as well as
all antennas cabling) prior to mounting the GeminiG3 unit to assure the feasibility of the
planned cable routing.
b)
Be sure to leave sufficient slack in each cable so the GeminiG3 unit may be removed from the
mounting bracket for servicing with the power applied and the antenna attached.
c)
GeminiG3 unit is ready for installation.
Cautions:
•
When drilling mounting holes, be careful to avoid damaging some vital part of the
vehicle such as fuel tanks, transmission housing etc. Always check how far the
mounting screws extend below the mounting surface prior to installation.
•
Use of drill
bit stops is highly recommended.
•
After drilling, remove all metal shavings before installing screws.
•
Do not overtighten self-tapping screws.

Once you have found a suitable mounting position for GeminiG3 radiomodem, hold the unit and
the unattached mounting bracket in the proposed mounting position and check that there is clear-
ance behind the unit for the heatsink, cables, etc. Check that the position provides a large enough
flat surface that the bracket will not be distorted when installed.
