E6240 Overview
Introduction
This kit is designed for the evaluation and development of applications using the
QT60160/QT60240 IC. The kit includes an evaluation assembly (E6240 – see
Figure 1),
cables
and QmBtn software. Each E6240 assembly has a serial (USB) interface allowing connection to a
computer for control and data viewing via QmBtn computer software.
This unique IC allows designers to create controls for various applications such as mobile phones,
remote controls and MP3 players, amongst others.
Refer also to the QT60160/QT60240 datasheet.

Setting Up and Using the E6240
Setting Up
To prepare the E6240 for use, proceed as follows:
1. Using the USB cable provided, connect the E6240 to the computer (see
Figure 2).
Both LEDs
on the E6240 light constantly to indicate that there is power to the assembly.
2. Install the QmBtn software; either method is acceptable:
a. Put the supplied CD in the CD drive of the computer. Copy the contents of the CD to the
computer. Double-click the QmBtn software to open it.
OR
b. Go to
www.qprox.com,
point to the
Support
tab and click
Download Archive.
Click
Software
and then the
qmbtn
(version 3.28 or later) link for the E6240. A dialog box
appears asking if you want to run or save the file that you are about to download. Click
Run.
This automatically downloads the QmBtn software.
If a dialog box appears saying “The publisher could not be verified. Are you sure you want
to run this software?” click
Run.
3. QmBtn software is displayed on the computer monitor. One LED is extinguished and the other
flickers continuously to indicate that the software is communicating with the E6240. Refer to
Section 2.2 and Section 3
for information about using the E6240 and QmBtn.

Recall All
on the QmBtn software.
3. Touch any key area on the E6240. Every time a key area is touched the corresponding key
area on the QmBtn software turns blue for the duration of the touch.
4. If the QmBtn software is not detecting, or detection is sporadic, decrease the detection
threshold slightly (NTHR,
