Cable Identification; Probe; Dap-125 Probe; Tone Function - AALogic TriTone User Manual

Since cross-coupling is minimized, the amplifier probe must be very close or
touching the pair to hear the tone. To confirm the correct pair is found, place the
probe tip between the Tip and Ring wires. There should be a significant increase in
tone on only the correct pair.

4.3.4 CABLE IDENTIFICATION

Tone can be used to locate cables. Connect the Green Ground clip to the
shield/ground and the Red clip to a vacant cable pair, both the Tip and the Ring. A
hand-coil probe and amplifier may be required to pick up the tone in the cable.

PROBE

The following describes the use of the three Probe functions: Tone, DSL frequency,
and DSL Scan.
5.1

DAP-125 PROBE

Connect at DAP-125 tone probe to the connector at the top of the TriTone
Transceiver. A ground connection is not required.
The DAP-125 tip is a unique design that enhances the amplification of the difference
in tone signal from one side to the other. Placing either side flat against the pair(s)
will amplify the tone signal. Placing the tip between the Tip and Ring wires of the
pair produces a much louder tone only on the correct pair when using TriPlex tone.
5.2

TONE FUNCTION

This mode is used to locate cables or cable pairs. A suitable tone source that sends 577Hz
or 987Hz tone, such as a TriTone 3, D-105, another TriTone Transceiver, or other tone
source, is required.
The TriTone Transceiver cannot be used to send and receive tone at the same time.

cables or pairs.
The tone is also heard from the internal speaker.
Frequency is changed by pressing the [FREQ] key. This toggles between 577Hz and
