„ Trouble Shooting
1. Application error is occurred and doesn’t start up
If the operating system is Window2000/XP, Please install AKM port driver in advance of run the
AK4673_TSC.exe.
2. MEAN value in AD OUT section does not change until click start button (cannot write control command to
AK4673).
Please set the port address correctly to your PC platform environment.
3. The mean, max, min value doesn't change wherever the pen is pressed 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. 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 connector and check the resistance value again.
