Why won't my TFT Monitor operate from the Y4E-COMM communication interface box or Ladder/Platform version electronics enclosure?

If your TFT Monitor will not operate from the Y4E-COMM communication interface box or Ladder/Platform version electronics enclosure, it could be due to incorrect wiring. Check the blue & white communication wiring. Another possibility is an incorrect INPUTS configuration. Verify that DIP switch #4 setting matches the system wiring (ON for voltage inputs, OFF for ground inputs).
