The CableMaster CM200 has a single button to both start a test and select other
functions and options. Presses of less than about 1 second (short press) and more than
1 second (long press) are recognized differently.
1. Cable Testing (short press):
With the CM200 off, each short press of the button
causes a cable test to be executed and the results displayed for 20 seconds before
powering off. “TEST” is displayed while testing is being performed. If another
short press occurs before the 20 second time out another test and 20 second time
out begin. If the button is pressed and held until “LOOP” is displayed and then
released, tests are run continuously and the display updated. The CM200 will turn
off automatically if there is no test result change for 5 minutes. A long press of the
button will cause the CM200 to exit cable test loop mode and enter mode selection
as discussed below.
2. Mode Selection (long press):
Starting with the CM200 off, a long press of the button
will cause the CM200 to enter mode selection. In mode selection the CM200 cycles
through cable test and tone generator modes. The mode displayed when the button
is released will begin execution. From powered off, the modes in order are:
•
LOOP:
Cable test that loops continuously until it times out of is exited by a long
press that reenters mode selection. Used to troubleshoot intermittent problems.
•
Four Tone Cadences (Hi Lo 1, Hi Lo 2, Hi, Lo):
The next four modes are all tone
generator modes with different sounds. The “H Lo” tones are made up of two
frequencies with different timings. “Hi” and “Lo” are single frequency. Once in a
tone mode, short presses change the pins carrying tone. The pins with tone are
displayed. In a tone mode, the CM200 will turn off automatically 30 minutes after
the test button press or by exiting to mode select with a long press.
•
OFF:
When the button is released with “OFF” displayed, the CM200 will power
off. Once in one of the above modes, OFF is the first mode offered upon exiting
to mode select. To select a different mode other than OFF, continue to hold the
button down and the next mode in rotation will be displayed next.
•
CABLE:
The cable test mode is the single cable test mode with 20 second timeout
that a short press from powered off executes.
