3 INSTALLATION PROCEDURE
3.1 Unpacking Unit
Carefully unpack the equipment and make a visual inspection of the unit for evidence of damage incurred
during shipment. If the unit is damaged, notify the carrier and file a claim. To justify a claim, save the
original shipping container and all packing materials. Do not return the unit to Garmin until the carrier
has authorized the claim.
Retain the original shipping containers for storage. If the original containers are not available, a separate
cardboard container should be prepared that is large enough to accommodate sufficient packing material
to prevent movement.
3.2 Electrical Connections
All electrical connections, except for the antenna(s) and shield ground, are made through a single, 62 pin
D-subminiature connector (see Figure 4-1). The card-edge connector may be used to terminate shield
grounds to the GTX 330 back plate. Table 4-1 lists the electrical connections of all input and output
signals. See Appendix C for interconnect wiring diagrams and cable requirements for each signal.
Required connector and associated hardware are supplied in the connector kit (P/N 011-00583-00).
CAUTION
Check wiring connections for errors before inserting the GTX 330 into
the rack. Incorrect wiring could cause internal component damage.
