3)
The LinkMaster™ Pro will power on immediately and indicate a test in progress by displaying
the TEST icon. Wiremap results and remote ID number will be displayed, as well as PASS if
correctly wired to T568 A/B standards. Beep tone also indicates a PASS. The test repeats every
5 seconds.
4)
For FAIL, refer to Interpreting Cable Test Results at end of instruction guide. Neither PASS or
FAIL icon will show for open or Miswire. Inspect wiremap numbers for these types of errors.
5)
Disconnect cable after test.
Note: Patch cables must be, no more than 10% of the total run length for accurate split pair indication.
To Measure Length
1)
Connect cable to main unit. (A remote may or may not be present at other end.)
2)
Turn on main unit by pressing any button. If not in length mode, press MODE until LENGTH is
displayed, than press SEL button. Cable length will be displayed.
- To adjust pF "length constant" parameters, use arrow keys.
- To change pair measured, press SEL to cycle through pairs 1-2, 3-6, 4-5, 7-8. (1-2 is
default pair and must be used for coax length)
- To change length between feet and meters, use SETUP mode.
Note: Default is 15 pF/foot; most Cat 5, Cat 5e & Cat 6 are very close to 15pF/foot – check with your
cable manufacturer for possible variances.)
Note: If a selected pair has a fault, the fault replaces the length reading on the LCD. In default mode,
if the 1-2 pair has a fault, the LinkMaster™ Pro automatically sequences to a pair without a fault.
Unknown Length Constant
If "length constant" is unknown for a particular cable, a known length of cable may be used to cali-
brate the constant. Measure fifty feet of cable and attach main unit to one end. Turn on unit, press
MODE until LENGTH is displayed. Press up/down arrow keys until 50ft is displayed, then use the pF
constant displayed to measure length of unknown cable. (Fifty feet or more is suggested to minimize
the resolution error; 1foot in 50 is 2% uncertainty).
To Test Coax
1)
Attach cable to be tested to the F-connector on the adapter . Insert adapter into Main jack on
LinkMaster™ Pro.
2)
Attach coax remote terminator to wallplate on the other end.
3)
Turn on main unit by pressing any button. If not in Coax mode, press MODE until COAX is
displayed, than press SEL button.
4)
Remote number and color will be displayed if cable passes. If cable fails, OPEN or SHORT will
be displayed.
5)
Coax length may be measured by setting length constant to manufacturer's specs and selecting
pair 1-2 in LENGTH mode. (no remote required)
To Generate Tone
1)
Turn on main unit by pressing any button. If not in tone mode, press MODE until TONE is dis-
played, than press SEL button.
2)
Press SEL until desired tone is selected. The up/down arrow keys select the pin or pair(s) to
carry the tone.
3)
Connect cable to be traced to main unit. For best signal, do not connect remote. Due to the
canceling effect of twisted pairs, the strongest signal is obtained by having one wire of a pair
carry tone. Selecting a single pin instead of a pair will do this.
4)
To turn tone off, press the MODE button until OFF is displayed, then the SEL button. The tone
will power off automatically after 2-1/2 hours.
Note: When using the coax adapter or alligator clip assembly, tone is connected only to Pin 1 and Pin 2
