Using the E1103: This kit is designed for the evaluation and development of applications using the QT1103-ISG Integrated Circuit IC . In this example the QT1103-ISG is run in Simplified mode. Refer to the QT1103-ISG datasheet for details see Ensure the E1103 Keyboard PCB is connected to J2 on the E1103 Main PCB. Select desired Adjacent Key Suppression AKS mode by moving the 2-way Jumper at J1. Insert the battery provided into the battery holder on the E1103 Main board. Ensure that the battery has the correct orientation negative - side to board or the E1103 will not work. Touch ON/OFF - The LED D11 under the standoff will illuminate to indicate power to QT1103-ISG. Touch any of the 10 key s on the E1103 keyboard and the corresponding LED s will illuminate. Auto Power-Off The E1103 will power off after approximately 15 minutes. Using the auto shut-off features of the QT102-ISG fitted An external power supply can be used instead of a battery. WARNING if an external power supply is used then the battery MUST be removed. Schematic: AKS Mode: On the E1103, AKS is a global setting. Refer to the QT1103-ISG datasheet for details. The AKS mode is changed by moving the 2-way Jumper fitted to J1 as indicated. If set to 'On' When touching multiple keys, only the LED associated with the key with the strongest signal is lit. If set to 'Off' When touching multiple keys, all associated LEDs will be lit. External Input: The E1103 can be connected to User electrodes, using connector J2. The values of C1-C10 sample capacitors may require changing. External Output: The output of the QT1103-ISG can be accessed using J3. The tracks at LK1-4 can be cut to disconnect the QT1103-ISG from U3, which is the IC used to used to drive the LEDs on the E1103 Main Board. Troubleshooting Problem E1103 does not work LED s stuck on AKS Mode unchanged after changing Jumper position Incorrect LED s light when keys touched Potential Solution If the Power LED is off, the 15 minute timeout may have been exceeded. Touch ON/OFF to restore power. If using a battery, check that the negative - side is facing the board. Check/replace battery. If using an external power supply, check that the correct connections have been made. Ensure the battery has been removed After changing AKS Jumper position, turn power off, then on again. After replacing the E1103 Keyboard, turn the power off, then on again. Turn power off, then on again. Check J2 connector pins on E1103 Main PCB and E1103 Keyboard are correctly aligned.

Using the E1103:

This kit is designed for the evaluation and development of applications using the QT1103-ISG Integrated Circuit IC . In this example the QT1103-ISG is run in Simplified mode.

Refer to the QT1103-ISG datasheet for details see

Ensure the E1103 Keyboard PCB is connected to J2 on the E1103 Main PCB.

Select desired Adjacent Key Suppression AKS mode by moving the 2-way Jumper at J1.

Insert the battery provided into the battery holder on the E1103 Main board.

Ensure that the battery has the correct orientation negative - side to board or the E1103
will not work.

Touch ON/OFF - The LED D11 under the standoff will illuminate to indicate power to

QT1103-ISG.

Touch any of the 10 key s on the E1103 keyboard and the corresponding LED s will
illuminate.

Auto Power-Off The E1103 will power off after approximately 15 minutes. Using the auto shut-off features of the QT102-ISG fitted

An external power supply can be used instead of a battery. WARNING if an external power supply is used then the battery MUST be removed.

Schematic:

AKS Mode:

On the E1103, AKS is a global setting. Refer to the QT1103-ISG datasheet for details. The AKS mode is changed by moving the 2-way Jumper fitted to J1 as indicated.

If set to 'On' When touching multiple keys, only the LED associated with the key with the
strongest signal is lit.

If set to 'Off' When touching multiple keys, all associated LEDs will be lit.

External Input:

The E1103 can be connected to User electrodes, using connector J2. The values of C1-C10 sample capacitors may require changing.

External Output:

The output of the QT1103-ISG can be accessed using J3. The tracks at LK1-4 can be cut to disconnect the QT1103-ISG from U3, which is the IC used to used to drive the LEDs on the E1103 Main Board.

Troubleshooting Problem

E1103 does not work

LED s stuck on

AKS Mode unchanged after changing Jumper position Incorrect LED s light when keys touched

Potential Solution

If the Power LED is off, the 15 minute timeout may have been exceeded. Touch ON/OFF to restore power. If using a battery, check that the negative - side is facing the board. Check/replace battery. If using an external power supply, check that the correct connections have been made. Ensure the battery has been removed

After changing AKS Jumper position, turn power off, then on again. After replacing the E1103 Keyboard, turn the power off, then on again.

Turn power off, then on again.

Check J2 connector pins on E1103 Main PCB and E1103 Keyboard are correctly aligned.
