2.5.1.1. Cable Settings
Before proceeding with «LFA» mode operations, it is necessary to select
the appropriate wire pair. This can be done either in the «SWITCH» mode
(2.4.1), or in the automated «LFA» mode menu (2.5.2).
If the number of wires has been reduced in the settings, the excluded
contact numbers will remain unavailable for selection until the settings are
changed.
EXAMPLE
A four-wire cable equipped with a 6P4C modular
connector (RJ14/RJ11, see Fig.23) is to be tested. The
cable is connected through an adapter to the 8-contact
(RJ45) socket of the Electronic Switch. In this case,
four contacts of the Electronic Switch input will not be
engaged. By applying the corresponding settings, they
can be eliminated from the testing procedure, which
will reduce the testing time significantly.
To open the cable setting menu from one of the
above modes, press “FUNC
”
. The user is offered the
following choice of cable types:
– twisted-pair cable (one, two, three, or four pairs);
– any multiwire cable (up to eight wires in a bundle).
Figs. 24-26 show the cable settings menu.
In Fig. 24, twisted-pair cable settings are shown,
the numbers representing:
1 – twisted-pair cable heading
2 – graphics showing the RJ45 input socket of the
Electronic Switch (with the engaged contacts
marked red and inactive contacts marked black)
3-6 – numbers of twisted pairs in cable, with the
current selection highlighted white.
7 – heading of a straight cable

pairs, or cores in a cable; press “ENTER
”
, to confirm

”
