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 Wiring Harness Installation
Allow adequate space for installation of cables and connectors. The installer shall supply and fabricate all
cables. All electrical connections to the GTX 23 are made through one 62-pin D-subminiature connector.
Section 4 defines the electrical characteristics of all input and output signals. Required connectors and
associated hardware are supplied with the connector kit.
See Appendix C for examples of interconnect wiring diagrams.
Check wiring connections for errors before inserting the GTX 23 into the rack.
Incorrect wiring could cause internal component damage.
3.3 Electrical Connections
All electrical connections, except for the antenna and shield ground, are made through a single 62 pin
D-subminiature connector (see Figure 4-1). 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 011-01012-01).
