Discovering Cabling Characteristics

Discover mode lets you quickly check wiremaps, measure

length, and determine if the cabling is connected to a

network or video device. Discover mode runs continuously

to help you isolate intermittent connections.

Discover mode tells you about the following:

For twisted pair cabling

• Wiremap

• Length

• Speed of an attached port (such as a hub or a

network interface card in a PC)

• Connection to telephone service

For 75 Ω coaxial cabling

• Continuity

• Length

• Indicates signal presence or connection to a device

(such as CATV service, VCR, DVD player, satellite dish,

or antenna)

• TDR (time domain reflectometry) plot. This shows

impedance changes along the cabling.

Results from Discover mode cannot be saved.

To test cabling in Discover mode:

Note

Not connecting a wiremap adapter or remote ID

locator to the far end of twisted pair cabling

limits the types of wiremap faults the tester can

detect.

1 Connect the tester to the cabling. Figures 6, 7, 8, and

13 on pages 20, 21, 23, and 33 show typical

connections using a wiremap adapter.

You may also connect to cabling connected to

network or video devices.

2 Turn the rotary switch to DISCOVER.
