2.3.3 Cabling and Wiring
For shielded wire applications, use Tefzel Mil-M-27500 or Mil-M-81044 shielded wire
with solder sleeves (for shield terminations) to make the most compact and easy to
terminate interconnect. Follow the wiring diagrams in Section 2.5 as required.
Allow 3 inches from the end of the wire to the shield termination to allow the hood to be
easily installed. Note the hood is a ‘clamshell’ type, and is installed after the wiring is
complete.
Allow 3 inches from the end of the wire to the shield termination to allow the hood to be
easily installed. Note that the hood is a ‘clamshell’ hood, and is installed after the wiring
is complete.
All wiring should be at least 24 AWG, except power and ground lines which should be at
least 22 AWG. Ensure that all ground connections are clean and well secured.
Note that the maximum wire size accepted by the high density D-Subminiature
connector is 22 AWG.
2.3.4 External Switches and Lamps
Switches and or annunciators must be selected to suit the application. If all lines are
picked at once, a single pushbutton (alternate action) or toggle switch may be used to
supply the ALL KEY line. Note that a single switch/lamp assembly can replace the
transfer switch and annunciators. This should be a lighted pushbutton switch
(SPST/SPDT), with positive action (i.e., push on, push off), and two legends to match
the desired NAV functions.
If serving as audio key relays (for boom microphones, etc.), the unit can be triggered by
in-line drop cords or other methods that supply an input to the appropriate key line.
If serving as NAV selector, annunciator lights should be connected through one or
more relay contacts to ensure indication of actual relay positions.
Fuses or breakers should be 0.5 Amp max for all applications. See the installation
drawings in Section 2.5.
2.3.5
Post-Installation Checks
Before connecting the RS16, check for 28 Vdc and ground on each of the respective
lines in the harness (depending on your particular configuration). Refer to the
applicable installation drawing in Section 2.5.
