TESTING CONTINUITY & CABLE IDENTIFICATION SIMULTANEOUSLY – INSTALLED COAX CABLE

Attach a numbered Test-n-Map™ ID Remote to the F-connector port

of each room. Write down the number of the remote and

of the room number/description in which it is placed for comparing/identifying the cables later.

Take the VDV Scout

Pro 2 to the distribution point

(often a wiring closet, switch or router at the other end of the cable

being tested).

Connect an unknown cable to the video port

on top of the tester using a barrel connector.

Press the video button

on the keypad to begin the test on the coax cable. The LCD will display “Video ID#” where “#” is the

ID number of the Test-n-Map™ ID Remote connected to the other side of the cable.

Compare this number to the remote number/room pair list you made in step 1

and mark the cable with a piece of labeled

tape, print a label or mark with a permanent ink pen. The LCD will also display the results of the continuity test. These results

should be interpreted using the

Wiring and Display Examples

section.

Repeat steps 4 and 5 for each unknown cable

until all have been labeled. You can use these labels to determine which rooms

should be connected to the cable splitter, or to troubleshoot intermittent connections in the future.

FREQUENTLY ASKED QUESTIONS

Does the VDV Scout

Pro 2 measure cable length?

The VDV Scout

Pro 2 does not measure cable length. The VDV Scout

Pro 2

does measure cable length.

Does the VDV Scout

Pro 2 LT use Time Domain Re ectometry (TDR)?

The VDV Scout

Pro 2 LT does not use TDR to measure cable length. The capacitive properties of a cable are used to determine

the cable length.

Does the VDV Scout

Pro 2 test the bandwidth of the cable?

The VDV Scout

Pro 2 only performs continuity related tests and split pair testing.

The screen is  ashing “3” and “6” with “U” underneath them when I try to test the continuity of an Ethernet cable.

What's wrong?

The VDV Scout

Pro 2 only tests continuity on cables terminated with the Self-Storing Remote or a Test-n-Map™ ID Remote.

It cannot test continuity on cables terminated with LanMap™ Location ID Remotes.

The screen is  ashing “For ID Test Only” with an ID number showing when I try to test the continuity of an Ethernet cable.

What's wrong?

The VDV Scout

Pro 2 only tests continuity on cables terminated with the self-storing remote or Test-n-Map™ ID Remotes.

It cannot test continuity on cables terminated with LanMap™ Location ID Remotes.

When I am testing continuity of an Ethernet or phone cable, there are 3 vertical hash marks moving across the right side of

the screen. What does this mean?

In continuity test mode, the vertical hash marks indicate that the tester is in loop mode. Tests are run continuously on the cable

in this mode, and the tester will turn off automatically if the same test result is returned for 5 minutes. To enable or disable loop

mode, hold the data button

in this mode, and the tester will turn off automatically if the same test result is returned for 5 minutes. To enable or disable loop

or the phone button

in this mode, and the tester will turn off automatically if the same test result is returned for 5 minutes. To enable or disable loop

for about 3 seconds. In coax continuity mode, loop mode is always

active. In tone generation mode, the vertical hash marks indicate the tone is active.

How do I know which end of a cable is bad?

It is not possible to directly determine which end of the cable is bad with the VDV Scout

Pro 2. Assuming that the cable is not

damaged somewhere in its length (i.e. it's a brand new cable), you can sometimes determine which end to redo based on the

diagnostic message. For instance, if the cable says there is this miswire:

Then you can usually determine which end just by looking closely again at your terminations through the clear plug. For opens

and shorts, it is not as easy to determine whether a pin is making contact with the wire just from observation. It could also be

bad at both ends.

Why don't I hear anything when the tester is in the tone mode?

In order to hear the tone, an analog tone probe must be used to pick up the signal emitted from the VDV Scout

Pro 2.
