Troubleshooting Information
Power LED does not illuminate
In case the power LED does not illuminate it is likely that the board is not powered.
Possible Solutions:
• Check the board is connected to your PC’s USB port.
• Change the USB cable or use a different USB port on your PC.
• Check if the PC is switched on.
LED 1 blinks fast
When LED 1 blinks fast (~10 Hz) the USB connection is not established towards the PC.
Possible Solutions:
• Make sure the Windows CDC driver is installed (refer to Appendix D. “Driver Installation Man-
ual”).
• Makes sure the MGC3130 Unit and the I
2
C™ to USB Bridge are already connected before plugging
in the USB connection (refer to Section 2.2 “Step 1: Build-up Development Kit”).
• Reconnect the board by unplugging and plugging in again the USB connection.
Signal streaming stops
Signal stream in Aurea GUI stops when there is no approach towards the sensing area. This behavior is
intended. When using the Aurea GUI, the Wake-up on Approach feature is automatically enabled.
Possible Solutions:
Disable the Wake-up on Approach feature in the Real-Time Control bar of Aurea by unchecking the
Approach Detection/Power Saving check box for continuous signal streaming.
No Position data displayed, Electrode signals are zero
Signal matching parameters have been mismatched and accidentally stored into the Flash.
Possible Solutions:
• Perform “Autoparameterization” in the AFE Parameterization of Aurea Setup tab. Make sure there is
no hand approach towards the electrodes during autoparamterization process.
• Restore the default Signal Matching parameters by re-flashing the original MGC3130 GestIC

LED 1 and 2 on I
2
C™ to USB Bridge are off
When LED 1 and LED 2 on the I
2
C™ to USB Bridge are off but the power LED is on, the PIC18F14K50
is in Bootloader Update mode and therefore not operating code. The PIC18F14K50 will start in Bootloader
Update mode in case the MGC3130 Unit is not connected to the I
2
C™ to USB Bridge.
Possible Solutions:
• Please disconnect the I
2
C™ to USB Bridge from USB. Connect the MGC3130 Unit and the I
2
C™ to
USB Bridge first and then plug in the USB connection.
