To get more information on using a shield in a touch application, refer to Shielding .

MTCH2120 can select a shield as a passive GND Shield or an active Driven Shield. By default, the passive GND Shield is selected. To select the Active Driven Shield, follow the steps below:

• Disable Button 11 using the Data Visualizer in the sensor control section
• Enable the Driven Shield using the Data Visualizer in the device control section
• Save the updated configuration to the MTCH2120 device by clicking the Save button
• Reset the device by clicking the "Software Reset" button. Or reset the device by power cycling the kit
• Insert the jumper into pins 1 and 2 of J11

When the Active Driven Shield option is selected, Button 11 becomes non-operational. The LED for Button 11 will toggle to indicate this status.
