http://itnetworks.softing.com
LCD DISPLAY SCREEN
The main tester has a high contrast LCD display screen, shown in Figure 2 below. The
LCD screen displays the following: test mode, pass/special cables, cable faults, shield
indicator, battery capacity, locator ID#, voltage detection, and wire mapping.
Figure 2. LCD Display Screen
TEST MODE
The top line of the display shows the cable type test mode (voice, data, and video).
TONE MODE
Tone Mode must be used with a tone tracer probe. The probe allows you to trace
cable wiring paths and identify potential faults by sound. The following icons appear in
the display screen when Tone Mode is in use:
Cadence – There are four cadence options: HI, LO, Hi-Lo1, and Hi-Lo2. The last selected
cadence appears in the lower right corner of the display screen.
Tone Path Selection – When tracing a video cable, the selected cadence is transmitted
on the coax pin (“P”), the coax shield (“S”), or both the pin and shield (“PS”). The
icons related to the current tone path selection appear in the lower left corner of LCD
display screen.
Note: The tone tracer probe is sold separately (refer to the Additional Accessories section)
LENGTH MODE
When the LENGTH/TONE button is pressed, the measured cable length (in units of feet
or meters) appears in the lower right corner of the LCD display screen and the “L” icon
appears above pins 7 and 8 in the Wire Map. The following values and icons display in
the screen when measuring cable length:
Edit Capacitance – When adjusting the length constant value for a cable, the “Edit
Cap” icon appears in the bottom of the screen. An “E” icon displays above pins 7 and 8
in the Wire Map to indicate you are in Edit Mode.
9
CableMaster 450
Length Constant Value – A value, measured in picofarads (pF) per foot or meter
appears in the bottom of the LCD display screen. This value corresponds to the
selected cable type and can be adjusted at any time. When viewing the length
constant value for a cable type, the “C” icon displays above pins 7 and 8.
PASS/SPECIAL CABLES
The second row of the display screen corresponds to the wiring structure of the cable
being tested. The CableMaster displays the following three icons:
Pass – The “Pass” icon appears if the cable has a properly wired 4-pair T568A/B data
cable, a 3-pair one-to-one wired voice cable, or a video cable with no faults.
X-over – This icon displays if a properly wired cross-over (uplink) data cable is
recognized. A crossover cable is a data cable with the 1-2 pair wired to the 3-6 pair.
This allows an Ethernet NIC card without MDIX capability to communicate by wiring
the transmit end of the cable to the receiver on the opposite end of the cable.
Rev – The “Rev” icon is displayed when the cable is a properly wired reverse-pinned
voice cable. A reverse-pinned voice cable has all wires on one cable connector
ordered by continuity and the connector on the opposite end of the cable has the
pins located in a reversed order. Pin 1 connects to Pin 6 on the opposite connector;
Pin 2 connects to Pin 5 and so on.
CABLE FAULTS
There are four possible error conditions on the cable: Fail, Short, Split, and Open.
Cable faults appear in the third row of the LCD screen. The faults are described in
Table 5 below. Refer to the Appendix for a visual representation of cable faults and
how they appear in the Wire Map.
10
http://itnetworks.softing.com
Table 5. Cable Faults
Cable Fault
Fail
Open
Description
A “Fail” error occurs when a cable’s wire connections do not follow
cabling standards.
• This icon will illuminate when any cable fault is detected
• Any miswired pin pairs will flash in the Wire Map
An “Open” error means a wire connection within the cable is not
continuous through the length of the cable.
• The pin pairs with errors will flash in the Tester Pin # field of the
Wire Map and will be blank in the Remote Pin # field
The “Short” icon appears when two or more wires within a cable are
electrically connected. This is also known as a short circuit.
Short
• A dash (-) will appear in the Remote Pin # field to indicate the
shorted pin pairs
• This dash will appear directly below the flashing pairs in the Tester
Pin # field
A split, also known as an AC signal fault, occurs when wires are not
twisted together according to their cabling standard.
Split
• This miswire commonly occurs with pins 3, 4, 5, and 6 in a data
cable
• The pin pairs experiencing the split will flash in the Remote Pin #
fields of the wiring map
Note: Open and Short errors take precedence over miswires and the appropriate icon(s)
will appear in the display screen.
If the pairs displayed in the Wire Map are flashing, the cable has a problem (split, open,
short, or fail). If the pairs are not flashing, the cable is wired properly and a “Pass” icon
will appear.
The accuracy of the CableMaster is limited to identifying the pin pairs with errors. It
cannot identify the individual pin experiencing the error.
11
CableMaster 450
SHIELD INDICATOR
The “Shielded” icon, appearing in the fourth line of the LCD screen, illuminates when
a shielded data cable is properly wired at both ends. The icon flashes if the shield
is shorted to a pin in the cable. The shorted pins display in the Wire Map and the
“Short” indicator appears.
WIRE MAP: TESTER PIN #
The top line in the Wire Map shows the pin numbers of the cables connected to the
main tester. If a cable fault is detected, the pin pairs experiencing the error will flash.
WIRE MAP: REMOTE PIN #
The bottom line of the Wire Map corresponds to cables connected to the remote
tester. The Remote Pin # field will show if the connected cables have errors (short,
open, fail, and split). The appearance of dash lines indicates shorted pins. No number
displayed in the Remote Pin Number line indicates Open pins. Pin pairs will flash if
they are split.
BATTERY LOW
The battery low symbol illuminates when the battery is nearing depletion. The symbol
flashes when the battery needs to be replaced.
Note: Results may be unreliable at this point so the battery should be replaced.
12
http://itnetworks.softing.com
LOCATION ID
The “ID” symbol, located in the third line of the LCD screen, appears when the
CableMaster is in Video, Data or ID Mode. When using the wire mapping remotes, the
“ID” icon will turn on and the remote ID number will display to its right. The ID number
is not displayed if an error occurs, such as “Open” or “Short”.
VOLTAGE DETECTED WARNING
If voltage is detected on any of the cable connectors, the “Voltage!” icon flashes. A
check for voltage is performed before each test and if found, no test is run. If the
icon appears, the tester should be disconnected immediately from the source of the
voltage. The tester automatically powers down in 90 seconds if the detected voltage is
not removed.

• Cable length in units of feet or meters displays in the bottom of the screen.
• The connector type last selected (voice, data, or video) displays in the top of the
screen.
• An “o” symbol bounces in the lower left corner of the screen to indicate activity.
Note: Measuring cable length is the primary function of the LENGTH/TONE button. If
you hold down the button too long, you will enter Tone Mode. If you mistakenly enter
Tone Mode, simply press the O/ID button and select the LENGTH/TONE button again
to enter Length Mode.

4.Change measurement units. The units can be changed from feet to meters and back
again by quickly pressing the VOICE and VIDEO buttons at the same time. When
the unit of measurement is set to feet, the “Ft” icon is displayed in the lower right
corner of the screen. When meters are selected, the unit of measurement is not
displayed.
5.Verify the connector type appearing in the display screen matches the connected
cable. If it does not match, press the cable type button corresponding to the cable
you plan to measure (voice, video, or data).
Note: If you do not select the cable type button mode matching the connected cable,
the tester will try to measure the previously tested cable and may skew the measured
length results.
6.Measure Entire Cable: After selecting the cable type button for the connected
cable, the measured length reading shown in the display screen is representative of
the entire cable.
Note: Voice and Video length modes automatically select and display the length of the
first pin pair without a fault. For cables with no faults, the length of pair 1-2 for Data
Mode and pair 3-4 for Voice Mode will automatically appear in the display screen
The Tester Pin # field is blank when the length reading for the entire cable is displayed.
Refer to Step 7 below for instructions on stepping through the wire pairs. Refer to the
LCD Display Screen section for a description of the Tester Pin # field.
7.Measure Pin Pairs: Press the cable type button again to measure the length of the
first pin pair. The number(s) for the pair being measured will display in the screen
(see Figure 14). Subsequent presses of the cable type button will cycle through
all the pairs and return to the length reading for the entire cable when you have
advanced past the last pin pair. The following icons appear in the display screen:
• The cable type icon appears at the top of the screen.
• Length of pin pairs in units of feet or meters displays in lower right corner of the
screen.
• The “L” icon displays indicating you are in Length Mode.
• A bouncing ball activity indicator appears in the lower left corner.
Note: If the selected cable pair is shorted, “SHORT” will display for the shorted pair and
the length readout is dashes.

The number of wire pairs is dependent on the type of cable you are testing. Data
cables have 4 wire pairs and voice cables have 3 pairs. If you are testing a video cable,
you will receive only 1 length measurement reading as a video cable has a single wire
pair.

8.Interpret display results and trouble-shoot potential cable faults.
VIEW THE LENGTH CONSTANT
1.While in Length Mode, press the LENGTH/TONE button again to view the length
constant. The following occurs in the display screen (see Figure 15):
• The “L” icon changes to “C” indicating the length constant is being displayed.
• The connector type (voice, data, or video) appears in the top of the screen.
• The length constant, measured in picofarads, displays in the bottom of the
screen.
Note: Each press of the LENGTH/TONE button toggles between displaying the
measured cable length and the length constant. After a few seconds the display
screen defaults back to the measured length.

ADJUST THE LENGTH CONSTANT VALUE
The CableMaster has default length constant values for voice, video, and data cables.
These values, shown in Table 8, are common length constants that apply to these cable
types. You can adjust the length constant value according to the specifications of the
cable you are testing.
Note: Bypass this section if the default values stored in the tester’s memory satisfy the
length constant values for the cables you are measuring.
Table 8. Default Length Constant Values
Cable Type
Length Constant (picofarads per foot)
Voice
17 pf/ft
Data
15 pf/ft
Video
15 pf/ft
Note: The length constant value last set for each connector type (voice, video, or data)
is stored in the unit’s memory. If you have not adjusted the length constant value for
any or all cable types, the default values will be stored. The length constant can be
adjusted at any time.
1.When in Length Mode, press and hold the LENGTH/TONE button until “EDIT CAP”
appears in the bottom of the display screen. The following updates occur in the
display screen (see Figure 16):
• The selected connector type (voice, data, or video) appears in the top of the
screen.
• An “E” will display in the right side of the screen to indicate you are in Edit Mode.
• The display screen toggles between the current length reading and the length
constant value.
Figure 16. Edit Mode
27
CableMaster 450
2.Adjust the Length Constant value for the cable you are testing. In Edit Mode,
the VOICE and VIDEO Mode buttons function as Up and Down (blue arrows are
denoted on the buttons). You can use these buttons to adjust the length constant
over a range of 10 to 40 picofarads per foot in 0.1pF/ft increments.
Note: While editing, the display screen toggles back and forth between the length
constant value and the measured cable length. You can edit the length constant value
when the length constant is displayed. Continuously pressing the UP or DOWN buttons
keeps the length constant on the display screen. Toggling begins when a few seconds
have lapsed after the last button press.
You can also edit the length constant value while the measured length is displayed in
the screen. This is helpful when you know the length of the cable. Press the UP/DOWN
buttons while length is displayed in the screen. Continue to adjust the length constant
until the reading matches the known cable length. The length constant is being
updated as the length display is changing.
3.Select the LENGTH/TONE button again to measure the connected cable under the
parameters of the new length constant.
Note: If the cable’s capacitance is too large, dashes will display for the length.
Changing the connector type or exiting Length Mode will store the adjusted length
constant in the unit’s memory for the next test. Up to three length constants can be
stored, one of each connector type.
LENGTH CONSTANT ACCURACY
The length constant refers to the electrical parameter used to measure length, in this
case, the capacitance of the cable per foot or meter. Accuracy is dependent on how
close the instrument can be set to the cable constant for the cable being measured.
The length constant can vary from cable to cable, of the same type produced by the
same manufacturer. It can also vary over the length of one cable because the length
constant is dependent on the physical properties of the cable, which may not be
consistent throughout the entire cable. The change in wire pair spacing through the
cable can vary the length constant along the length of the cable.

CableMaster Pins
T568B is electrically identical to T568A, but swaps the green and orange pairs. Either
standard will work as long as the same standard is used at both ends of a run or patch
cable. Missing standards A and B creates a cross-over cable. In the event of a cross-over, the
“X-over” icon will display and mismatched pins will flash in the wire map.
T568A DATA CABLE WITH SPLIT PAIRS
A common error in building a cable is to put all the wires in pin sequence - 1-2, 3-4, 5-6, 7-8.
This will produce correct continuity, but the pairs are designated to be on pins 3-6 and 4-52 in
the middle of the connector for compatibility purposes. As the designated wire pairs are not
matched according to wiring standards, the “Split” error will appear. The mismatched pins
will flash in the wire map of the LCD screen.

1 and 2 pins on the main tester are connected to pins 2 and 1 at the remote-end. The pins
with this error are flashing. The “U” for the remote pin numbers indicates an unrecognizable
continuity was detected that is neither a short or open. An ID remote connected to the Tester
when in cable test mode would also have shown this error.
