DESCRIPTION
The VDV Pro can be powered on by pressing any of the four buttons. VDV Pro powers off automatically
after 20 minutes of continuous testing of a single cable. Disconnecting the cable restores the tester to
normal function. Most power-on modes will timeout in 20 minutes. The tone mode will power off after
2 1 ⁄ hours. The VDV Pro will turn on in the last mode used before turning off. The back light is toggled
2
on and off by holding down SEL for 2 seconds or more. At power on, the back light is always on. The
back light turns off automatically 3 minutes after being turned on. (with or without test activity)
Upon completion of the test, the wire map, 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 is the connector pin numbers of the remote.
• If there is a miswire, the numbers on the second line will indicate the pin numbers detected.
• If no connection was detected for some of the pins, the second line will be blank in those pin locations.
• If a short is detected, the second line will have a flashing " "in that position, and the specific short
condition displayed on the third line.
• If a split pair is detected, the pins affected will flash on the second display line. The specific split
condition will be displayed on the third line.
• If there are multiple errors to display on the third line, the messages will be displayed in sequence
until all are displayed.
• Under "ID", the number of the remote being used will be displayed.
There are five modes of operation as described below plus a setup function. In any mode, pressing the
MODE button causes the mode select screen to be displayed. The OFF message is usually the first one
displayed. Continued pressing of the MODE button will cycle through the other modes. Pressing the
SEL button causes the currently displayed mode to be entered.
Cable Test – If there is no remote, press any of the buttons to turn on the VDV Pro. The tester
will then test for shorts, opens, and split pairs. The results are displayed as messages on the LCD.
Whenever a new cable assembly is inserted for testing, press the SEL button to start a new test cycle.
Partial and erroneous results can occur if not done.

Length – The length mode measures the length of a cable by measuring its capacitance and using the
capacitance per unit of length (length constant) to calculate the length. The length is displayed on the LCD
along with the current value of the length constant. The SEL button changes the pair being measured in
a 1-2, 3-6, 4-5, 7-8 and auto-select sequence. The pair number is displayed next to the length except
in auto-select mode. If a selected pair has a fault, the fault replaces the length reading on the LCD. In
auto-select mode, the VDV Pro automatically selects a pair without a fault. Use the auto-select or 1-2 pair
settings to measure the length of a coax cable connected to the F-connector. The length
constant is changed with the up and down arrows. The CAL icon is on while adjusting the constant.
Note: If the far end of the cable is connected to a Network Device (Hub, Switch, etc.), the VDV Pro will
display "Network??".
