E1106 User Manual
3.2 How to Use the E1106 QWheel/QSlide Assembly
1. Place the E1106 QWheel/QSlide on a level surface.
2. Keeping clear of the E1106, click Cal All Keys or Cal Wheel/Slider (as applicable) on the
QT1106 Demo software. Do this every time the E1106 is unplugged from the computer.
However, if the grounded transparent backplate has been removed from the E1106 then the
E1106 must also be recalibrated each time it is moved.
3. Depending upon whether the QWheel or QSlide is connected, move your finger about the
wheel/slider area of the E1106. As you do so the Wheel Indicator shows the last reported
touch position (see Figure 3, page 5) and the Numerical Indicator shows the numerical
equivalent (see Figure 3, page 5). When you remove your finger, the last position touched will
be locked on the display.
4. If the QT1106 Demo software is not detecting, or detection is sporadic, decrease the detection
threshold slightly (Detection Thresh).
5. Refer to Section 3.3, Page 6 onwards, for details of which parameters you can change.
3.3 QT1106 Demo Parameters
(refer to the QT1106 datasheet for more information)
The QT1106 Demo software comprises a main window and a setup dialog box. The different
parameter areas simulate the effect that changing options has on the device’s performance. Any
option which is not available appears dimmed. Refer to Figure 3 and Figure 4, Page 5 to see a
depiction of the QT1106 Demo software.
3.4 Main Window
The Wheel/Slider Indicator shows the position of touch on the E1106 and its numerical equivalent
is shown on the Numerical Indicator (from 0 to 255, depending on the resolution – see
Section 3.5.1). This changes in real time as the position of touch on the E1106 changes.
The Keys Indicators show when a key is being touched; the key turns red for the duration of the
touch.
Calibrate each key individually by clicking that particular key or calibrate them altogether by clicking
Cal All Keys.
Calibrate the wheel/slider by clicking Cal Wheel/Cal Slider.
Access the setup parameters by clicking Setup.
The connection indicator (green) is constant when the E1106 is connected to the computer,
flickering when it is not.
Click Exit to close the QT1106 Demo software.
3.5 Setup Dialog Box
3.5.1 Wheel/Slider Area
Slider Mode – the default setting for the software is the wheel. Select the check box to change the
setting to the slider. A slider representation will be shown in the main window.
Detection Thresh - sets the amount of signal change which will cause the E1106 to register touch
detection. The values are 0…255, default = 12. Move the cursor over the Detection Thresh bar
until the cursor turns into a double-headed arrow. Holding the left mouse button down, move the
slider left or right to select a new threshold. The actual value is shown above the bar and changes
in real time as the slider moves.
6 of 14
Resolution – sets the resolution of the wheel/slider; default = 7 bits. Move the cursor over the
Resolution bar until the cursor turns into a double-headed arrow. Holding the left mouse button
down, move the slider left or right to select a new resolution. The number of bits is shown at the
side of the bar and changes in real time as the slider moves.
2 Bits: 4 positions (0...3)
3 Bits: 8 positions (0...7)
4 Bits: 16 positions (0...15)
5 Bits: 32 positions (0...31)
6 Bits: 64 positions (0...63)
7 Bits: 128 positions (0...127) (default)
8 Bits: 256 positions (0...255)
Calibration – this indicator lights to show when wheel/slider calibration is occurring.
Signal Error – this indicator lights to show that the signal has the wrong polarity, usually due to
E1106 assembly movement (when the transparent backplate is not fitted). Clicking Cal Wheel/Cal
Slider will resolve the error.
Detection – this indicator lights when a touch is detected on the wheel/slider.
3.5.2 Keys Area

E1106 User Manual
QMagic Prox – this enables proximity mode on key 7 (when the check box is selected), allowing
the product to auto power up or activate its display with hand approach.
Note: once activated it can only be deactivated by clearing the check box and resetting the chip.
This has to be done by physically unplugging the device. Clearing the check box is not enough.
3.5.3 AKS Modes Area
AKS Modes – Adjacent Key Suppression - this patented feature works to prevent multiple keys
from responding to a single touch. It suppresses touch from weaker responding keys and only
allows a dominant key (or group of keys) to detect. Click an AKS Modes icon to select a new AKS
mode. In the main window the keys and wheel/slider backgrounds change color to indicate the
grouping of the new mode (if the Show AKS Groups in Main Window check box is selected).

E1106 User Manual
3.5.5 General Area
Max On Duration – the device can time out and recalibrate each key independently after a
continuous touch detection that lasts for the chosen ‘Maximum on-duration’ (MOD). This en sures
that a key can never become ‘stuck on’ due to foreign objects or other external influences. After
recalibration the key will continue to function normally. The nominal delay is selectable to be 10s,
20s, 60s, or infinite (default), though the actual delay may vary in some operating modes (see the
QT1106 datasheet for more information).
Detect Integrator – Detect Integrator (DI) filter confirmation reduces the effects of noise on key
states. The DI mechanism requires a specified number of measurements that qualify as detections
(and these must occur in a row) or the detection will not be reported. In a similar manner, the end
of a touch (loss of signal) also has to be confirmed over several measurements. The QT1106
provides a choice of either two or six DI measurements for confirming start of touch; end of touch
always uses two measurements. Select the appropriate check box.
3.5.6 Low Power/Sync/Sleep Mode Area
Low Power/Sync/Sleep – this indicator is lit when the QT1106 IC is in a Low Power/Sync/Sleep
mode. Although a Low Power/Sync/Sleep mode may be selected in the Operating Modes area,
when a key or the wheel/slider is touched the indicator goes out. This is because for the period of
detection/touch the mode automatically changes to Free Run and then back to the original mode
when detection/touch is finished.
Free Run if in Detection – select the Free Run if in Detection check box to automatically change
the mode to Free Run whenever a touch is selected. This makes the response quicker, otherwise
the device goes back to sleep for the allotted time between measurements.
Low Power Burst (LPB) – select the LPB check box to initiate a burst after each SPI transfer or
/SS Wake pulse, clear the check box to stop the LP bursts.
3.5.7 Other Options
Restore Defaults – click this button to restore the default settings.
Show AKS Groups in Main Window – select this check box to show the selected AKS group with
the keys and wheel/slider colored to show the grouping in the main window.
Enable Sound on Touch – select this check box to enable a sound to be heard when a key or the
wheel/slider is touched.

Power Supply
The QT1106 power supply should be locally regulated using a three-terminal device, to between
2.8V and 5.0V.
Wheel Element
The wheel element is resistorless and consists of etched copper electrodes.
Slider Element
The slider element is resistorless and consists of etched copper electrodes.
Sampling Capacitors
C5…C14 are the Cs sampling capacitors. Increasing their value will increase sensitivity and
resolution of measurement, but will also tend to make the response time slower.
LED
The LED will switch off momentarily when keys/wheel/slider are touched, and also when touch is
removed. When the touch moves around the wheel/slider the LED will flicker on and off for the
duration of the movement of the touch.
