Trouble Shooting

1. Application error is occurred and doesn’t start up

If the operating system is Window2000/X, Please install AKMport driver in advance of run the

AK4183_070.exe.

2. MEAN value in AD OUT section does not change when click start button (cannot write control command to

AK4183)

Please set the port address to your PC platform environment.

3. The mean, max, min value doesn't change wherever the pen pushes down on the panel.

There is a possibility of the trouble of the contact of the relay connector (plat 8pin-8-wire female dip converter)

that connects the touch panel. Please open JP3, 4, 5, and 6 on the evaluation board, measure panel seat resistance

(XP-XN, YP-YN), and check the resistance. Generally, the panel seat resistance is hundreds of Ω. There is a

possibility that the touch panel is not correctly connected if the resistance is over thousands of kΩ. Please

connect the relay connector and check the resistance value again.
