4. Initial setting

4-1. EEPROM setting

Depending on that calibration is performed in either TSC-30/IC or host, you can select whether EEPROM
is used or not to store the correction data. EEPROM selection can be set via pin number 50, where
hardware reset release enables the setting.

4-2. Communication mode setting

Communication mode setting for serial/USB is performed by setting pin number 37 to

“H” or “L”. When

power supply is turned on, or hardware reset is released, pin number 37 is read to turn on in either USB/
serial mode.

No both communication schemes are used at a time. After the
hardware reset, if setting is performed with jumper switch, the
setting is enabled by power supply restart or hardware reset.

4-3. Touch screen mode setting

Touch screen mode setting for 4-wire, 5-wire or 8-wire is performed by setting pin number 60 and 61 to

“H”

or

“L”. When power supply is turned on, or hardware reset is released, pin number 60 and 61 are read to

turn on in either 4-wire, 5-wire or 8-wire mode.
