Network (NTWK) Cable Test Mode - The

Resi-Tester™ assumes the 8-position jack

on the main unit and the remote will be used

for connecting the tester to the cable run to

be tested. The TIA/EIA 568A/B standard is

used to define the pairs. Connector pins

1-2, 3-6, 4-5 and 7-8 are the pairs defined

by this standard. The A and B standards

are the same except for color-coding and

are indistinguishable from each other by

electrical testing. The tester will display the

“Pass” icon when all 8 pins are correctly

wired in a one-to-one order. If all 8 pins are

correctly wired with the 1-2 and 3-6 pairs

crossed , the “Pass” icon will be displayed

along with a flashing “Uplink” icon. Uplink

cables are also known as crossover or

T568A-to-T568B cables and are commonly

used to connect two computers or two hub/

switches directly together.

After turning on the network cable test

mode, subsequent presses of the NTWK

button of less than 2 seconds, forces a new

test cycle to begin immediately upon release

of the button. This is useful to immediately

begin a new test when attaching a new

cable to the Resi-Tester™. Holding the

NTWK button down for more than 2

seconds, turns the split pair test off. The
