2.4 Special Tools Required
Some of the connectors use crimp contacts. The tables below identify crimp tools required to ensure
consistent, reliable crimp contact connections for the rear D-sub connectors. The tables define one source
for the crimp tool. Alternate equivalent tools may be used.

Install the retainer ring for the coaxial connectors using external snap ring pliers, Diamond D32R or
equivalent. Note that the access holes inside the tray are enlarged and offset to provide access for the
pliers.
2.5 Equipment Mounting
2.5.1 Cabling and Wiring
Wiring should be installed in accordance with AC 43.13-1B Chapter 11. When wire separation cannot be
achieved, the following issues should be addressed:
•
The cable harness should not be located near flight control cables and controls, high electrical
capacity lines or fuel lines
•
The cable harness should be located in a protected area of the aircraft
•
Do not route cable near high-energy sources
Refer to the interconnection diagrams in Appendix C for the appropriate wiring. Once the cable
assemblies have been made, attach the cable connectors to the rear of the mounting tray. Route the wiring
bundle as appropriate. Use 22 to 24 AWG wire for all connections except for power. Use 20 AWG for
power/ground. Avoid sharp bends.
2.5.2 Mounting Tray Installation
The GDL 90 does not require forced-air cooling; however, when mounting the GDL 90, avoid locating
the GDL 90 near sources that produce high levels of heat. The tray can be installed in a variety of
locations, such as the electronics bay, under a seat or behind the rear baggage area. Refer to Figure 2-1
and Figure 2-2 for suggested location. Leave sufficient clearance between the GDL 90 and any
obstruction. Install tray in accordance with AC 43.13-2A Chapter 2 Radio Installations. Tray should be
mounted to a surface known to have sufficient structural integrity to withstand additional inertia forces
imposed by a 6.4-pound unit. If it is necessary to build a shelf or bracket to mount the GDL 90 tray or it
is not certain that the chosen location is of sufficient structural integrity, refer to Appendix D.
Refer to Figure 2-3 for the GDL 90 tray dimensions. The tray can be mounted vertically using four 8-32
pan head screws (MS35206 or AN526 cadmium plated carbon steel.) It can also be mounted horizontally
using four 6-32 100° counter-sunk flathead screws (MS24693 or AN507R cadmium plated carbon steel.)
For installation in rotorcraft, the tray must be mounted vertically. See 561-0290-xxx GDL 90 Helicopter
Installation Supplement for additional rotorcraft installation requirements.
