1 Use and operation
1.1 Housing and construction
The housing consists of two black plastic shells which are screwed together. The
underside rests on rubber feet. For charging the battery in the charging tray, two
contacts are fitted on the underside of the housing.
The front is painted dark silver. On the right-hand side is an unpainted black vertical
strip. For simple, basic operations there are three buttons and a concave, round
wobble plate with four contact points (top, bottom, left and right, non-rotating) at top
right. Two LEDs inform the user about the operating state and charge state.

1.2 Operation, controls
The SIMpad SL4 is a small, convenient, ergonomically shaped data terminal which is
particularly easy to operate. The Windows CE3.0 operating system uses menus and
windows as the user interface, and is very similar to other Windows operating systems.
For users, this means an easier, familiar method of operation.
Instead of a mouse, the one uses a pin to do input directly on the screen. The usual
functions such as "single-click“ (to select an object), "double-click“ (to execute an
object) and "drag and drop“ (to move an object) are supported.
Some PC applications and websites react when the mouse position indication goes
over an active object, e.g by highlighting the object. As there is no mouse position
indication on the screen of the SIMpad the “mouse-over” function is not supported.
The user can do text input using an optionally displayed keyboard field or handwriting
recognition.
By using the wobble plate, the user can move the picture vertically. Horizontal
movement of the picture is unnecessary with most web pages and other applications,
thanks to the high screen resolution. The left-hand position of the wobble plate
corresponds to the "Escape“ key for leaving a function. The right-hand position of the
wobble plate causes an input ("Enter“ key).
The user can navigate in the pull-down menus via the wobble plate by using the right
mouse button.
Two LEDs inform the user about the state of the device. The top, yellow LED is used to
indicate that the battery is being charged. When it is switched off during charging the
battery is fully charged.
The bottom, green LED lights if the device is operating (operating states "running“ or
"idle“, see 1.3).
1.3 Operating states
In normal operation, the SIMpad SL4 is switched on and off using the on/off button.
When the user switches on again, he or she is back in the same place as before the
SIMpad SL4 was switched off. Switching off does not cause data to be lost or
programs to be left. In fact, the SIMpad SL4 is never really switched off but in sleep
mode.
Operating states
Running full operation, normal power consumption
Idle reduced operation, reduced power consumption
Sleep device off, memory is supported, low power
consumption
Off Device off, memory is not supported, no power
consumption (state as supplied, empty batteries)

2.2 Processor, graphic chip
In the SIMpad SL4, an IntelâStrongARMâSA-1110â, 32-bit RISC processor with a
nominal clock frequency of 206 MHz is used. This processor provides very high
computing power combined with very low power consumption, unlike conventional x86
processors.
To achieve optimum control of the high-resolution SVGA screen with its 16-bit colour
depth (65536 colour levels, “high colour” resolution with photo quality), an additional
graphics chip is used. This makes the screen set-up faster and the computing power
higher because of the reduced load on the processor.

2.3 Screen, touch panel
Most pages in the World Wide Web are 800 pixels wide. To show a picture always at
full width, the SIMpad SL4 has an 8.4" screen with SVGA resolution (800 x 600 pixels).
This is a screen with TFT technology, which gives a flicker-free and smear-free picture
with higher colour saturation.
Controlling the illumination unit (BLI) makes practically continuous adjustment of the
screen brightness possible. The software allows the user to choose from 7 illumination
levels (see 5.4.13.5).
An 8.4“ 4-wire analog resistive touch panel is fitted over the screen. The touch signals
are analysed by the A/D converter (see 2.1).
2.4 Memory
2.4.1 Organisation of memory
The division and organisation of memory is shown in Fig. 2 . The memory consists of
two parts:
•32MB flash memory (read, restricted write, no execution in place)
•64MB SDRAM (read, write, execution in place)
The flash memory retains the data even without a power supply. It contains the Image
with the operating system (OS) and the standard programs in compressed form
(configuration programs, Pocket Word etc.), as well as the persistent memory
(Persistent storage file system, Persistent registry) and the Bootloader/BOST.
The flash memory allows for a maximum 5000 write procedures. Therefore it must not
be used as a hard-disk-like memory for data files.
The remaining RAM (approx. 60 MB) is divided into Object Store and Program
Memory. Data (texts, images, parameters etc.) which is used by the executed
programs is stored in the Object Store. This is also used as a RAM file system, in
which additional programs which have been downloaded from the Internet or loaded
via the serial interface can be stored.
On initial start (see 5.2.3) of the SIMpad SL4, required parts of the operating system
and standard programs are decompressed and transferred to the RAM by the Dial-up
Bootloader (boot from flash). This safes a lot of memory space in RAM which can be
used for the Object store and the Program Memory.
The Program Memory is the working memory for executing programs. Additional
programs which are already stored in the Object Store must be copied to the Program
Memory to be executed, and therefore require twice the RAM of their size.
The user can choose the division of the remaining memory into Object Store and
Program Memory (see 5.4.13.15). The Object Store must have a minimum size, even
if no additional programs are loaded, because this part is also used for data of
standard programs and the operating system.
The Persistent Storage file system cannot be used for storing data in the flash
memory, since extra software is required for this purpose.

2.4.2 Saving settings in persistent memory
The user has the option of saving the registry in the persistent memory. The registry
contains:
•System parameters
•Customer specific settings
•Mail addresses (see 5.3.2.1)
•Favourites (links, see 5.3.3.2)
As the registry is saved in the persistent flash memory, the data is retained even if the
battery is completely discharged, neither will it be affected by a hard reset or cold start,
except for the “Factory reset” (see 0). The "Store settings“ program can be started in
the start menu (see 5.2.1).

2.5 Audio, microphone, loudspeaker
The function of the audio codec (coder/decoder) is carried out by the A/D converter.
This codec supports duplex speech quality. The mono digital audio signal has a
resolution of 12 bits (linear) or 8 bits (non-linear), corresponding to telephone quality.
The music quality is limited by the size of the loudspeaker, but the effect is better via a
headset (see 4.1).
The microphone is tested with regard to the hardware functionality. For any application
using the microphone, a corresponding driver will have to be installed.

Frequency range FO-4.5kHz
Sound pressure 86dB
Diameter 20mm
2.6 Power supply
The permanently fitted battery can be charged by being connected directly to a power
supply unit, or in the charging shell, which is itself connected to the power supply unit.

4 Interface
4.1 Serial/headset interface(“Lumberg” plug)
The universal interface ("Lumberg“ plug) is used in Siemens mobile telephones (from
S25 and higher) and provides the following part interfaces for the SIMpad SL4:
•serial interface (RS-232; V.24 level conversion 12 V)
•audio headset interface
Via the serial interface, the SIMpad SL4 can communicate with a PC for data
exchange (see 5.4.5), or with peripherals (external keyboard, modem, mobile
telephone). For this, a crossed (9-pin) serial cable is used (see 6.1.3). Data
transmission is possible in one direction at a time only (no duplex).
The serial cable for Siemens mobile phones has an integrated level conversion.
Therefore it cannot be used for the SIMpad SL4 which requires a simple cable without
level conversion (see 6.1.3).

4.3 IrDA interface
Via the IrDA interface, the SIMpad SL4 can communicate with an IrDA peripheral
(external keyboard, mouse, printer, mobile telephone). The IR diodes of the two
devices must be in visual contact and not more than 0.3m apart. The SIMpad SL4
supports the SIR standard (Serial Infrared), with a transmission rate of about 115kbps.
Mobile telephones with the Siemens IrDA interface (S25, S35) and those of the most
important manufacturers with such an IrDA interface can communicate with the
SIMpad SL4. However, they also require an integrated modem. Between the SIMpad
SL4 and the mobile telephone, only a pure data transmission connection can be set
up, for dialling to an ISP or another server. Other types of data exchange (SMS,
telephone directory entries) are not supported by software.
Printers of the most important manufacturers with an integrated IrDA interface can be
controlled. For printers without an IrDA interface, an appropriate IrDA adapter can be
connected to the parallel interface of the printer.

4.4 SmartCard
The SmartCard makes personal identification (electronic, personal key) possible, and
gives the option of encrypting and decrypting the data stream with higher-order
asymmetrical encryption. The SmartCard interface is provided according to the ISO
7816 (Part 1-3) standard, and includes a bi-directional data line and a clock line. No
application for using the SmartCard is offered initially.
Caution: In France a different standard called AFNOR-Standard is in use. These card
types do not work on the SIMpad smart card reader.
