When connected via the configurator to a TX3-8U/C unit the event viewer is indicating that I have the wrong unit registered , even though, I am sure this is not the case?

• The ribbon and or the keypad issue:
  • Power recycle the unit then try to connect:

If the unit comes back online, then Key pad or ribbon connector will require change-out at a later date. If it happens again, replace the keypad and ribbon cable
