If the operating system is Windows 2000/XP, Please install AKMport driver first.

AK4182A)
Please set the port address to your PC platform environment.

There is a possibility of the trouble of the contact of the relay connector (plat 8pin-8-wire converter) that connects
the touch panel. Please open JP2, 3, 4, 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 value is over thousands of kΩ. Please connect the relay connector
and check the resistance value again.
