perry p Posted February 24, 2014 Report Share Posted February 24, 2014 Hi, I just purchased the model v570-57-t20b-j. I have not used one of these before. I have used the older version of the 570 with great success. The one I recieved will not respond when i try to use the touch screen. I updated the firmware and loaded a known good program with no success. Is there anything different between this model and the old one or do I have a defective one?

dan Posted February 24, 2014 Report Share Posted February 24, 2014 Hi Perry, Please contact support@unitronics.com and we would be happy to assist further. If you power down the unit, hold you finger on screen, and power the unit up, does it enter bootstrap mode? Are you using any additional serial ports? thanks, Dan Quote Link to comment Share on other sites More sharing options...
