ADA Keypad Non-Responsive

IDC Pro Pocket Guide — Troubleshooting

1. Keypad Location

   The ADA keypad is located on the right-hand side, behind the splash panel. It is powered by the screen.

   There is a black USB that feeds power from the screen to the ADA, and communication from the ADA to the screen.

   Every time the board is power cycled, it calibrates for a microsecond. You should see the top arrows flash quickly.

2. Check Connection

   Check for proper connection at the ADA board.

   Remove the splash panel and check the connection on the upper left hand corner of the board.

   Make sure that the black USB is plugged in.

3. Check USB Cables

   Note: If both connections are properly connected and you still have no response unplug the black USB and one of the gray USB cables. Then plug the black USB cable into the USB port you just remove the gray USB cable from. If the ADA touchpad now works this indicates you have a bad ADA power USB port and may need a new SBC board.
