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 ‘x’ 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.
Note: Connecting a coax remote to the LinkMaster™ Pro with the unit off will power up the unit but
the second line of the display will be blank. To use the coax remotes, the LinkMaster™ Pro must be
on and in the coax test mode as described
below.
There are four 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.
Pretest (One ended testing)
– If there is no remote, press any of the buttons to turn on the
LinkMaster™ 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 LinkMaster™ 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 LinkMaster™
Pro will display "T Ring Network??", "xbase-T Network?" or "Network?" (based on the number of con-
ductors terminated into the device).
Tone
– The tone mode generates four different tones for use with tone tracers on all pairs, a selected
pair or a selected pin. The SEL button selects one of the four tone sounds provided. The up and down
arrows scroll through the pairs and pins that have signal on them. The LinkMaster™ Pro has constant
tone amplitude over the life of the battery and two tone amplitude of normal and half (HI on pair and
Low on pin).
Note: When using the coax adapter or alligator clip assembly, tone is connected only to pin 1 and
pin 2.
