PARAGRAPH
B.
The cable harness with pins attached may now be inserted in the appropriate numbered slots marked on the 18 pin
connector, P101 (Refer to Figure 1-9). Proceed as follows:
1.
The pins cannot be inserted upside down in the translucent connector housing. Right side up, it slides in
effortlessly. Be sure to push it all the way in, until a “click” can be felt, heard or even seen (by turning the
translucent housing over).
2.
It is not necessary to pull back on the lead itself except to test for the “locking feature”, and then only with a
moderate pull.
3.
If a pin is erroneously inserted into the wrong connector positions, or if at some later time a circuit change
is desired, the in can be easily removed. Slip the flat narrow blade portion of the Molex contact ejector tool,
HT 1884 (VPN 80006) into the mating side of connector housing upside down so that you can see the blade
slice in and up to the stop. This action picks up the locking key and allows the lead and pin to slop out of its
position using a light pulling action on the lead. Neither pin nor position has been damaged allowing re-
insertion in the same or another positions.
C.
Coax Connector:
Refer to Figure 1-8 for the details in connecting the right angle BNC connection (P301) to the coaxial cable. Pay
particular attention when stripping the Coaxial cable. Allow sufficient insulation to remain on center conductor. This
will prevent the notched out on the 50 ohm match from making contact with the center conduction and shorting out.
Complete the soldering as described in Figure 1-8 and install the connector into the mounting tray.
D. BNC
Connector:
For termination instructions of the BNC connector on the coaxial cable for connection to the aircraft VHF antenna,
refer to the instructions n the BNC package.
