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

Antenna Installation

Install the antenna according to the antenna manufacturer's instructions.
3.3

Antenna Cable Connectors

The antenna cable requires a BNC plug connector. Follow BNC connector manufacturer instructions for
assembly of the BNC connector.
3.4

Electrical Connections

All electrical connections to the GMA 350/350H, including the marker beacon antenna and shield ground,
are made through two 44-pin D-subminiature connectors. Tables in Section 4 define the electrical
characteristics of all input and output signals. Required connector and associated hardware are supplied
in the connector kit (P/N 011-02302-00). See figures in Appendix B for interconnect wiring diagrams.
Check wiring connections for errors before inserting the GMA 350/350H into the rack.
Incorrect wiring could cause internal component damage.
