Thanks for the replies guys, i took both your advice and went through my driver setup and it was ok and then connected the terminal directly to the plc upstairs and it worked perfect, so i ran new cat5 cables to downstairs and so far everything is Also, while searching through your forum i found where sparky had mentioned the functions for the small pot on the back of the screen, we had a defunct screen here where the touch was about half an inch too low and therefore no use to us, so i used the calibrate touch function and hey presto, good as new again HUGE thanks for the help guys, very grateful
