Upon completion of a telephone or network 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
“Tel” or “Ntwk” icons are on.
In the coax 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 “Coax” icon turns on when a test is in progress.
As mentioned above, the tone generator operates in Telephone, Coax and Network modes. The different modes are provided 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 (TEL, COAX or NTWK) followed by the TONE button. If the Resi-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, selecting a different pin to drive in
network mode will not change the driven pin in coax mode. Pressing any cable test mode button will turn off the Resi-Tester™ when in tone mode.
The Resi-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.
After turning on the telephone cable test mode, subsequent presses of the TEL button of less than 2 seconds long, forces a new test cycle to begin
immediately upon release of the button. This is useful to immediately begin a new test when attaching a new cable to Resi-Tester™. Holding the
TEL button down for more than 2 seconds, turns the split pair test off. The “Split” icon and the word “OFF” appearing on the screen momentarily
indicate this. Another long press will toggle back to the split pair testing, and so on. When split pair testing is not required, as in the testing of flat
satin cable, the split pairs can be turned off, so a cable may pass based on continuity only.
The Resi-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/EIA 568A/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.
After turning on the network cable test mode, subsequent presses of the NTWK button of less than 2 seconds, forces a new test cycle to begin
immediately upon release of the button. This is useful to immediately begin a new test when attaching a new cable to the Resi-Tester™. Holding the
NTWK button down for more than 2 seconds, turns the split pair test off. The “Split” icon and the word “OFF” appearing on the screen
momentarily indicate this. Another long press will toggle back to the split pair testing, and so on. When split pair testing is not required, as in the
testing of flat satin cable, the split pairs can be turned off, so a cable may pass based on continuity only.
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 generator 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 through in turn until the button is released. The tone pattern options are Hi, Lo, HiLo1 and HiLo2. The HiLo
options are dual or warble tones of differing pattern duration. Pressing any button other than TONE turns off the Resi-Tester™. The tone will turn
off automatically after about 2.4 hours.
The Resi-Tester™ monitors for voltage being present on the jacks during each test cycle. If voltage is found, the “Volts!” icon is
displayed and testing stops until the voltage is removed.

Instructions for Use
Resi-Tester™ powers off automatically 9 minutes after the last button press in cable testing modes and after 2.4 hours in
tone mode. Be sure to install a battery if using for the first time, see battery installation section.
CABLE TESTING
To Test a Patch Cable
(see caution about cables with bad plugs above)
1) Plug one end of patch cable into main unit.
2) Plug other end of cable into remote unit.
3) Press TEL or NTWK as appropriate for the jack the patch cable is connected to. The Resi-Tester™ will turn on and begin a testing. If tester was
already on, press TEL or NTWK to initiate a new test. Results are invalid if a cable is attached during a test in progress.
4) To turn Resi-Tester™ off, press COAX button.
To Test Coax
To Place Tone on a Cable
1) Attach one end of cable to be tested to F-connector on main unit.
2) Remove remote unit from main unit by squeezing the remote lightly between the thumb and forefinger through the openings provided in the main
unit and pull out of storage pocket. Remove coax remote from storage pocket on backside of remote and attach to the other end of the cable to be
tested.
3) Press the COAX button to turn on the unit and begin testing. The results are updated about once a second.
4) To turn Resi-Tester™ off, press TEL or NTWK buttons.
1) Connect cable to be traced to a main unit jack. For best signal, do not connect a remote to the other end. Due to the shielding 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. For coax, the
Tone is best applied to the shield and the shield cannot be grounded.
2) Turn on Resi-Tester™ by pressing the button associated with the connector to be used followed by pressing the TONE button. Short presses of the
TONE button will select a different pin. Holding down the TONE button for more than 2 seconds will select a different tone pattern.
3) To turn Resi-Tester™ off, press any button except TONE. The tone will turn off automatically after about 2.4 hours.
INTERPETING CABLE TEST RESULTS
from
to
reverse pair
The Pass icon will be on if the cable has all pins properly connected per T568A/B for network cables or per 3-pair USOC for telephone cables. The
Fail, Short, Open or Split icon will be on if there is a wiring error. The wire map will display the end-to-end connections measured whenever
possible.
The Pass icon will also be on with a flashing Uplink icon if a network cable has the 1-2 and the 3-6 pairs transposed to indicate a properly wired
uplink (crossover) cable. In Telephone mode, the Rev icon will flash if all connected pins are in reverse order and the Pass icon will also be on if all
6 connections are present. Telephone modular plug cables used between the wall jack and a phone set are usually reverse pinned.
(See failure example drawings) The three classes of faults discussed below are in order of severity. The severity has to do
with the ability of a more severe error to mask less severe errors. For example, if there is a short in the cable, miswires and split pairs may not be
detected for the pairs involved in the short fault.
The pair has a low resistance connection from one wire of the pair to the other wire of the pair or to any other wire in the cable or the
shield. A short is indicated by the Short icon being on and flashing -'s in the appropriate pin positions on the second line for the pin numbers involved
in the shorts plus a flashing S icon if the shield is shorted to a pin.
A wire or both wires of a pair are not connected to the correct pins at the other end of the cable. The wire map shows the pin numbers
line 1 (main)
line 2 (remote). A
is a special case of a miswire in which the pair is wired to the correct pair of pins or to another
designated pair of pins, but the two leads are reversed. The Resi-Tester™ is able to test for split pair errors as long as the wiring errors are in pairs.
The Fail icon and the pin numbers, which are miswired, will be flashing.
- A split pair is an error in the twisting of the wires together within the cable. The cables generally are made up of eight wires twisted
together in 4 pairs. These 4 pairs are designated as pairs by the wiring standards and are intended to carry a signal and its return. 1&2, 3&6, 4&5 and
7&8 are the pairs designated by T568A/B for a RJ45 jack or plug. A cable can be wired with correct continuity but not with correct pairing. This
most often happens when the cable is terminated consistently at both ends, but in the wrong order. A dynamic or AC test is required to detect this
type of error.
The Split icon and the pin numbers on the first and second line of the wire map with split pairs flash
when there is a split pair error.
Resi-Tester™ has the ability to turn off the split pair error testing. Pressing the button for the current cable test mode for more than 2 seconds turns
off the split pair testing. The “Split” icon and the word “OFF” appears on the screen momentarily to indicate this. The split pair testing will resume
the next time the tester is turned on, or may be toggled back on by another 2 second press of the current test mode button.
Definition of Errors -

Split Pair
If the only error is a split pair error, the cable has correct continuity. If cross talk is not a concern, as in flat satin cable, the cable is
good if the only error is the split pair error.
