APPENDIX C INTERCONNECT DRAWINGS
This section contains wiring interconnect details and examples for the connections necessary for the
installation of the GTX 35R/45R Series transponders.
Each figure contained in this section has notes that must be followed. These general notes apply to all of
the figures contained in this section.
 Unless specified differently, all wires are 24 AWG or larger.
 Power and ground connections are 22 AWG wire for run lengths less than 10 feet, if not, use 18
AWG.
 Use oversize contacts in the connector kit for wire sizes greater than 22 AWG.
 In 14 VDC installations, use two power pins and two ground pins for power and ground
connections.
 In 28 VDC installations, use only one wire for power and ground connections.

Antennas and associated cables are shown for reference only.
 If practical, power and ground wires should be routed separately for each transponder.
 Route grounds and wire separately to improve safety if there is a wiring or grounding system
failure.
 Designations for ground connections:
Shield Block Ground
S
 Shield ground terminations to the connector backshell must be 3.0 inches or less in length.

Ground terminations of interfaced equipment can vary. Refer to the manufacturer's installation
manual for information.

HDSB Ethernet wiring may use 22 AWG or 24 AWG aircraft grade category 5 Ethernet cable:
Or MIL-C-27500 shielded twisted-pair cable.

Installations can require alternate port configurations and are acceptable provided the equipment
interfaces and data formats are available on alternate ports.
