terrydeltasigmacorp.com Posted May 21, 2015 Share Posted May 21, 2015 I have a Turbo Clipper board that the D3 LED was RED on at my customers facility. The manual says that D3 being Red means the watchdog timer has tripped. I brought that same board back to my place and powered it up and D3 is on Green. When the LED was red the ethernet did not work. Could this happen if the 5V powering the board was low? That is the only thing that is different between here and there and I did not check the power supply while I was there. Thanks Link to comment Share on other sites More sharing options...
