Digital I/O
Outputs
The tester’s outputs are “sink” outputs. When activated they will connect (or sink) a voltage to
ground, in effect turning ON the output circuit. The outputs are capable of sinking up to a
nominal 24 volts and 500 milliamps. To limit the output current, always ensure adequate
resistance between power supply and the output. When switching a voltage between 12 and 24
volts, the output will allow a slight current flow (about 1mA at 24 volts) when the output is off.
Current cannot flow when the normal state of each output is off. Using the
Digital Outputs
settings in User Preferences tester interface, you can set up test events to turn an output ON and
OFF. One test event sinks the output to ground, allowing current flow through the output circuit.
A second event resets the output line to its original OFF state. If you select the same event to
set and reset the output, the tester will sink the output for a 10 millisecond pulse. For
instructions on setting up
Digital Outputs,

Each of the test events that can change output status is listed below.
Event Name
Description
Bad Light Off
The front panel “Bad” light is off.
Bad Light On
The front panel “Bad” light is on.
Cable Attached
The tester sensed a connection between 2 or more test points from
an attached cable.
Cable Counted Bad
The tester counted a cable “bad” in the test summary.
Cable Counted Good
The tester counted a cable “good” in the test summary.
Cable Removed
The tester sensed the cable is removed.
Count Intermittent
The tester counted a cable “intermittent” in the test summary.
Failed Self Test
The tester failed self-test when turned on.
Good Light On
The front panel “Good” light is on.
Good Light Off
The front panel “Good” light is off.
Intermittent
The tester detected an intermittent error in the assembly being
tested.
Learn Completed
The tester completed the cable learn process.
Learn Started
The tester began the cable learn process.
LV Test Done (P/F)
The tester completed the low-voltage test; either pass or fail.
LV Test Failed
The low-voltage test failed.
LV Test Passed
The low-voltage test passed.
LV Test Started
The tester started the low-voltage test.
Ready to Test
The tester is at the test screen, ready to test; the cable may or may
not be attached.
Will Count Good
If the cable were removed, it would count as “Good”.
Will Count Bad
If the cable were removed, it
would count as “Bad”.
