USB Mode
Light Touch can be connected to a host machine via a USB cable that plugs
into the USB Micro-B port. The USB Mode control panel can be accessed from
the ‘Settings’ menu:
Figure 14 – Screenshot of ‘USB Mode’ icon within ‘Settings’ menu
The default USB mode is ‘ActiveSync’ mode, which allows Light Touch to be
controlled from a Microsoft Windows PC. Further details are available in the
separate ‘Application Guide’ document.
In order to connect using USB ActiveSync mode, a device driver is needed for
the host PC. Instruction relating to the installation and use of these drivers is
contained in the appendices of this document.
Light Touch also supports ‘USB Mass Storage’ mode, which allows Light
Touch to appear as an external drive to a host PC or Mac.
Mass storage mode supports a higher transfer rate and the ability to connect
without using a device driver. However, whilst Light Touch is connected as a
mass storage device, it cannot access its own file system.
The main screen of the USB Mode control panel allows the connection type to
be selected as shown below.

There are two different mass storage modes because Light Touch contains
two separate memories that are accessible to the user. The ‘internal’ Flash
memory has a capacity of 4GB and is present at all times. The ‘micro-SD’
Flash memory is an optional memory card that may be fitted into the device
via the external micro-SD card slot.1
If mass-storage (micro-SD) mode is selected, the user will first be prompted
to make sure that a micro-SD card is inserted.
Figure 16 – Screenshot of prompt to check micro-SD card inserted
When Light Touch is put into mass storage mode, the following screen will be
displayed for the duration of the transaction.
Figure 17 – Screenshot of mass storage mode message
When a USB cable is connected, the appropriate memory within Light Touch
will appear as a network drive on the host machine. Once any file transfers
have completed, Light Touch should be restarted using the power button. On
power-up, Light Touch will return to ‘ActiveSync’ mode.
1Note that the external micro-SD card slot is only accessible by removing the back
panel of the outer plastic cover. To remove the cover, first remove the screw at the
bottom of the back panel and then lift off the panel, starting from the bottom.

Developing Custom Applications
Introduction
The Light Touch LT1221 Series is designed to be an application platform that
users can create their own content for. The system is designed to enable
users to create applications using either one of two popular software
platforms:
•Adobe Flash Lite 3.1 – the Adobe Flash development toolset is currently
used by over 1,000,000 developers. A wide range of visually-rich, interactive
applications can be developed quickly and easily without the need for
complex coding. As such, this method of creating applications is accessible
to a wider range of content developers such as graphic designers and
artists. Flash Lite 3.1 can also be used for the development of complex
applications due to its support for ActionScript 2.0 code.
•Microsoft .NET Compact Framework 3.5 – this powerful development
environment gives developers maximum control over the system at the
expense of more complex code development. Standard tools such as
Microsoft Visual Studio can be used to create applications and the
developer can get low-level access to system peripherals which would not
be accessible via Flash Lite 3.1
The Light Touch LT1221 Series runs Microsoft WinCE 6.0 R3 as the operating
system and includes all of the files needed to run applications written in both
Flash Lite 3.1 and .NET Compact Framework 3.5.
Connecting to the Unit
Light Touch can be connected to a host computer via USB. The USB
connection can be run in two modes: USB mass storage mode (i.e. providing
drag-and-drop file transfer support, or ActiveSync mode (i.e. providing file
transfer and debug capabilities for Windows PCs). Information on how to set
the USB mode is provided in the ‘Light Touch Settings -> USB Mode’ section
of this document.
For USB ActiveSync mode, the recommended method of connecting to the
Light Touch from a PC is slightly different depending on which operating
system the PC is running:
For Windows XP:
•Ensure that the host PC has Microsoft ActiveSync software installed
http://www.microsoft.com/windowsmobile/en-
us/downloads/microsoft/activesync-download.mspx . With the Windows XP
operating system, it is recommended to use ActiveSync version 4.5
•Plug in the power to the Light Touch and turn the unit on
•Connect the Light Touch unit to a PC via the USB cable. The required USB
cable is: Micro-USB (Type B) to Full Size USB (Type A).
