3 INSTALLATION PROCEDURES3.1 Unpacking the unitCarefully unpack the equipment and make a visual inspection of the unit for evidence of damage incurredduring shipment. If the unit is damaged, notify the carrier and file a claim. To justify a claim, save theoriginal shipping container and all packing materials. Do not return the unit to Garmin until the carrier hasauthorized the claim.Retain the original shipping containers for storage. If the original containers are not available, a separatecardboard container should be prepared that is large enough to accommodate sufficient packing material toprevent movement.3.2 Wiring Harness InstallationAllow adequate space for installation of cables and connectors. The installer shall supply and fabricate allcables. All electrical connections to the GTR 200 are made through one 37-pin D-sub standard densityconnector (P2001) and one BNC connector for the antenna (P2002). Section 4 defines the electricalcharacteristics of all input and output signals. Required connectors and associated hardware are suppliedwith the connector kit (Table 2-3).See Appendix D for examples of interconnect wiring diagrams. Construct the actual harnesses inaccordance with the aircraft manufacturer authorized interconnect standards. After the cable assembliesare made, route the wiring bundle as appropriate. Use cable ties to provide strain relief for the coax andcable assemblies.
