LK204-25 Display clears text and seems to reset w/keypad use
Posted: Wed May 24, 2006 6:54 am
Hello,
I've got a couple of devices that are controlled by micros that have the LK204-25 displays attached to them. When I'm running the equipment (A lot of RF in the area) and I have the keypad plugged into the display, the display loses it's text and the backlight flickers on and off. If I unplug the keypad, the display works fine. (Note: When I have the device turned on, everything works, it stops working when I'm actually running/driving the equipment) I've tried emi sheilding on both sides of the keypad but that didn't do anything for me.
Any thoughts or suggestions? I've tried other displays and other keypads and they do the same thing.
