Returning to initial status at power activation

• Transferring display data/displaying on LCD: command (1 Byte) + data (256 Bytes)

• Others: command (1 Byte) + data (1 Byte)

• Commands can be accepted only when all bits coincide; otherwise, they are not acknowledged

• Additional commands will not be received until the communicatio n of commands (1 Byte) and data (256 or 1 Byte) is completed

• There is no time limit from the beginning to end of data receipt

• Commands may be executed consecutively (no need to wait between commands)

• Irregular commands or data is not recognized

• Initial status at power activation: LCD display o , LED o (brightness 1/20, color o )

COMMANDS & DATA FOR SMARTSWITCH & SMARTDISPLAY

Handling

1. The IS Series devices are electrostatic sensitive.

2. Limit operating force to keytop to 100.0N maximum, as excessive pressure may damage the LCD device.

3. The IS series devices are not process sealed.

4. If the LCD is accidentally broken, avoid contact with the liquid and wash o any liquid spills to the skin or clothing.

5. Clean cap surface with dry cloth. If further cleaning is needed, wipe with dampened cloth using neutral cleanser and dry

with clean cloth. Do not use organic solvent.

6. Recommended soldering time and temperature limits: 5 second s maximum @ 270°C maximum

7. Do not exceed 60°C at the LCD level.

Storage

1. Store in original container and away from direct sunlight.

2. Keep away from static electricity.

3. Avoid extreme temperatures, high humidity, gaseous substances, and all forms of chemical contamination.
