Digital I/O

Digital I/O

Digital I/O on your CH2, 8100, and 4200 Series tester makes it easy to customize the tester with:

  • Foot switch for “Start Test”
  • Palm buttons for hipot safety
  • Status lights
  • Device locks
  • Stampers
  • Audio Output

With digital I/O you link an event in the test to an input or output on the tester’s I/O connector. Some of the events available:

  • Cable Attached: the tester sensed a connection between 2 or more test points.
  • 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.
  • Failed Self Test: the tester failed self-test when turned on.
  • HV Delay Started: the tester started the delay before the HV test.
  • HV Test Delay Done: the tester completed the delay before the HV test.
  • HV Test Done (P/F): the tester completed the high voltage test with either a pass or fail.
  • HV Test Failed: the high-voltage test failed.
  • HV Test Passed: the high-voltage test passed.
  • HV Test Started: the tester started the high-voltage test.
  • HV Test Aborted: the tester aborted during the hipot test.
  • Is Intermittent: the tester detected an intermittent error in the DUT.
  • Count Intermittent: the tester counted a cable “intermittent” in the test summary.
  • 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. The test passed or failed.
  • 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 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”.
  • Good Light On: the front panel “Good” light is on.
  • Good Light Off: the front panel “Good” light is off.
  • Bad Light On: the front panel “Bad” light is on.
  • Bad Light Off: the front panel “Bad” light is off.
