Fit the plug outer, associated boot, and boot insert.

Connect the socket contacts using either of the following techniques:
•
Crimp
: Crimp the socket contacts onto each of the conductors using the correct crimp tool and
positioner, setting the wire size selector to “3” for 24AWG wire.
•
Solder
: When soldering the socket contacts onto each of the conductors, ensure that there is
no solder or flux residue on the outside of the contact. Care should also be taken that the
individual conductor insulation does not peel back with the soldering heat, allowing possible
shorts when assembled into the plug shell.

Fit four dummy contacts into the unused 12 way circular connector locations (6, 7, 8 and 10), to
provide strength and sealing. Push the contacts in from the pin insertion side.

Insert the eight RJ45 contact pins into the pin insertion side of the 12 way circular connector in
accordance with Figure 114.
It is easiest to insert the pins from the center out, in descending order of Trimble location number,
that is, 12, 11, 9, 5, 4, 3, 2, 1. Push the contacts in so that the shoulder on the contact fits into the
hole in the plug shell. When all contacts have been fitted, push them in further to engage with the
locking mechanism in the plug shell. This can be done by applying pressure to the contact with a
small diameter stiff object, such as tweezers.
