The VDV MultiMedia Cable Tester is turned on by pressing any one of the four momentary function buttons and begins
testing in the mode for the button pressed Telephone (VOICE), Data Network (DATA), Video/Security (VIDEO), or
Tone Generator (TONE). The corresponding connectors at the top end of the tester are labeled the same as their
mode switches. An LCD icon for the currently selected mode will be on or flashing on the screen. To turn the
VDV MultiMedia Cable Tester off when in one of the cable test modes, press the button for a different cable test
mode, but not the TONE button. Pressing the TONE button will start the tone generator in the Tel Tone, the Video
Tone or Data Tone mode, depending on the current cable test mode. The tone mode will be discussed in detail later
on in this section.
Upon completion of a voice or data cable test, the wire map display, ID and any faults are displayed. The top line of
numbers on the display represents the connector pins on the main unit. The second line of pin numbers represents
the connector pin numbers of the remote, normally being the same as the top line for a one-to-one wired cable. If
there is a miswire, the pin numbers on the second line will indicate the pin numbers detected and the "Fail" icon
will be on. The icon and the pins involved in the error will flash. If no connection was detected for some of the pins,
the first and second line of pin numbers will be blank in those pin locations. If a short is detected, the second line
will have a '-' in those positions along with the "Short" icon being on. If a split pair is detected, those pin positions
on the first and second line will be flashing the pin numbers detected from the remote and the "Split" icon will be
flashing. If there are multiple errors to display, there will be a combination of the above error displays. The ID icon
will have a number directly to the right of it, indicating the remote ID number detected from the remote. A new test is
in progress whenever the "Voice" or "Data" icons are on.
In the video mode, the "Open", "Short" or "Pass" icon will be on to indicate the results of a test. If the cable
passes, the "ID" icon will be on as well as a remote ID number, on the bottom line of the display. The "Video" icon
turns on when a test is in progress.
As mentioned above, the tone generator operates in Voice, Data and Video modes. The different modes are pro-
vided so that the pins or pairs being driven with a tone signal are displayed in terms of one of the three connectors.
The specific mode is selected by pressing one of the cable test buttons (VOICE, VIDEO or DATA) followed by the
TONE button. If the VDV MultiMedia Cable Tester was off when the TONE button is pressed, the last cable test mode
used will be selected. The tone generator saves the driven pins for each mode independently. For example, select-
ing a different pin to drive in network mode will not change the driven pin in video mode. Pressing any cable test
mode button will turn off the VDV MultiMedia Cable Tester when in tone mode.
1. VOICE Cable Test Mode – The VDV MultiMedia Cable Tester assumes the 6-position jack on the main unit
and the remote will be used for connecting the tester to the cable run to be tested. This mode uses the 3-pair
USOC standard to define the pairs. Connector pins 1-6, 2-5 and 3-4 are the pairs defined by this standard. The
tester will display the "Pass" icon when all 6 pins are correctly wired in a one-to-one order. If all 6 pins are
correctly wired in the reverse order, the "Pass" icon along with a flashing "Rev" icon will be displayed. Standard
telephone cables used between a phone set and a wall jack are usually reverse-pinned.
2. DATA Cable Test Mode – The VDV MultiMedia Cable 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/EIA568A/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. For shielded data cable, the remote ID will flash
alternately with "S" to indicate presence of shielding.
3. VIDEO COAX Cable Test Mode – The VDV MultiMedia Cable Tester can test for open, shorts and ID.
4. TONE – The tone mode generates audio tones for use with tone tracers on all pairs, a selected pair or a selected
pin. The signal generated on a pair has the signal on one pin and the complement of the signal on the other pin
of the pair, yielding a nominal 10 volts peak-to-peak across the pair. The pin number of the pin or the letters
"P" (for pin) and "S"(for shield) being driven with tone and the currently selected tone pattern are displayed on the
screen along with the "Tone" icon and the icon for the connector assumed to be used. Once in the tone genera-
tor mode, the TONE button steps to the next connector pin(s) drive option for presses of less than 2 seconds.
When the TONE button is pressed and held down for longer than 2 seconds, the tone pattern options are stepped
