The sample display shown above, indicates that the PairMaster
is connected to the cable with Remote Identifier #15 attached
to the far end. Pair 1/2 is O.K., pair 3/6 has a failure, pair 4/5 is
O.K., and pair 7/8 has yet to be tested.
SPECIAL CABLE TESTING
The PairMaster is designed to test 4 pair cables wired in ac-
cordance with the EIA/TIA 568 wiring standard. However, many
LAN installations, such as Ethernet or Token-Ring, require an 8
pin RJ-45 connection but only use two of the four pairs (see fig.
6). These two types of configurations are no problem for the
PairMaster.
When testing two pair Ethernet (10 Base- T) cables, the
PairMaster will give actual test results for pairs 1/2 and 3/6.
On pairs 4/5 and 7/8 the unit will display ‘OP” and light up the
associated FAIL LEDs. As long as the green PASS LEDs light
up on pairs 1/2 and 3/6, the two pair cable can be used for
Ethernet installations.
