The VDV Scout

Pro 2 LT uses the capacitive properties of a cable to measure its length. One end of the cable should be connected
to the corresponding port on the top of the tester. The other end should be left disconnected or attached to the self-storing remote.
The Length Constant sections below discuss the best practices to follow when measuring length in order to achieve the most
accurate results.
The length constant refers to the electrical characteristic of a cable used to characterize length. Every cable has an associated length
constant in units of picofarads per foot. Setting the length constant on the tester is important to obtaining an accurate measurement
from the VDV Scout

Pro 2 LT. The default length constants are as follows:
The length constant can sometimes be provided by the manufacturer of the cable (see EDITING LENGTH CONSTANT section). You

consistency of the cable along its length.
The length constant can vary from cable to cable, even of the same type produced by the same manufacturer. It can also vary
over the length of one cable because the length constant is dependent on the physical properties of the cable, which may not be
consistent throughout the entire cable. The change in wire pair spacing through the cable can vary the length constant along the

TESTING CONTINUITY - OVERVIEW

8-wire Ethernet cables can have an additional set of errors. A miswire simply means that the pin on one side of the cable is not
connected to the identical pin on the other side of the cable (for example, pin 2 on one side is connected to pin 6 on the other side).
Certain pairs of conductors are required to be twisted together from endpoint to endpoint. These errors are called split pairs, and
can be present in cables that don't have any miswires.
Testing continuity is not the same as testing bandwidth. Other testers exist for verifying the amount of data that can pass through
a cable.
Connect one end of the cable under test
to the RJ45 port (if you are testing an Ethernet cable) or RJ12 port (if you are
testing a phone cable) located at the top of the main tester body. If testing a wall port, connect a known good patch cable
from the wall plate to the appropriate port at the top of the main tester body.
Connect the other end of the cable
under test to the corresponding port on the testing remote (LOCATION ONLY ID remotes
cannot be used). If testing a wall port, connect a known good patch cable
from the wall port to the appropriate port on the
testing remote.

The first and most convenient way to identify installed cables is by using location ID remotes. Using location ID remotes, you can trace
any manual tracing.
The second way to identify cables is using the VDV Scout
®
Pro 2's built-in analog tone generator. The tester will place a low-frequency
voltage on the cable. By using an analog tone probe (Klein Tools VDV526-054, VDV500-060, or most other manufacturers’ analog
tone probes, sold separately), a cable can be identified by the tone it is carrying. This technique only allows one cable to be traced per
tone generator, but has additional benefits like the ability to trace a cable manually behind certain wall materials, or trace unterminated
cables of non-standard types.
LanMap™ Location ID Remotes cannot be used to verify continuity
snaps into the bottom of the tester or the Test-n-Map™ ID Remotes (included in some kits, or sold separately) can be used to test
continuity of data or phone cables. However,
CoaxMap™ Location ID Remotes can be used to verify continuity and identify
coax
cables. Any numbered CoaxMap™ Location ID Remote can be used to test continuity.

T568A Cable with a Short and Open:
T568A Cable with Split Pairs:
T568A Cable with Split Pairs:
A common error in building a cable is to put all the pairs in pin sequence 1-2, 3-4, 5-6 and 7-8. This will
produce the correct continuity, but the pairs are designated to be on pins 3-6 and 4-5 in the middle of the connector for compatibility with
phone wiring. This wiring error is only detected by the split pair test since the designated pairs are not twisted together.
