2.3 The Scanner
The 7535 can support the following scanners, internal or external:
• 1D scanner
• PDF 417 2D scanner
• image scanner
Only one scanner is installed in the 7535, but a second handheld scanner can be connected via the tether port.
Internal scanners can be triggered from the trigger switch on the 7535’s handgrip (if present) or from the Scan button on the 7535’s keyboard. External scanners can only be triggered from their own trigger switch.
2.3.1 Scanner Control Services
This top level service (SCS) is responsible for supporting a variety of Physical Scan
Drivers (PSD), and presenting an API to applications. It receives decoded scan data from the drivers, performs any configured translations, and delivers the data to the appropriate application(s).
2.3.2 Non-decoded Laser Scanners
These scanners present raw data to the terminal. Internal and external non-decoded laser scanners are controlled by the main processor. Activation of the scanner trigger(s) or the keyboard scan button(s) causes the main processor to initiate a scan with the appropriate scanner. The peripheral controller acquires the raw scanner data and feeds it to the main processor.
The non-decoded scan driver is responsible for receiving this data from the peripheral controller and decoding it before passing it to the Scan Control Service, which performs any configured translations and delivers the data to the appropriate application(s).
2.3.3 Decoded Laser Scanners
These scanners process their raw data themselves, presenting formatted data to the terminal. Both 1D and 2D decoded laser scanners are supported by the 7535. The scanners will be connected to one of the serial ports and controlled by the main pro-
7535 Hardware Reference Guide 9
Chapter 2: The Hardware
Imaging Scanners cessor. Activation of the scanner trigger(s) or the keyboard scan button(s) will initiate a scan with the appropriate scanner. The decoded scan driver is responsible for receiving scan data and passing it to the Scan Control Service.
2.3.4 Imaging Scanners
The 7535 can support an imaging scanner; both internal and external imaging scanners are supported. Psion Teklogix provides a driver for this scanner.
2.4 The Display
The 7535 is available with a 240x320-pixel display, either monochrome (64 shades of grey) or colour (256k colours). The contrast of the display can be adjusted from the keyboard via hot-keys, and is automatically temperature-compensated.
2.4.1 Touch Input
Touch input is an option for the 7535’s display. The touch driver controls the hardware directly to receive touch-down, touch-up, and movement events. Touch events are passed to the application via the operating system.

2.9.1 The Docking Port
The docking port allows the terminal to be placed in a cradle that allows battery charging and connection to peripherals.
7535 Hardware Reference Guide 13
Chapter 2: The Hardware
The Docking Port
Available peripherals include chargers and a Portable Docking Module (PDM) that
provides connections for USB host port, USB client port, and a serial port. See “The
Portable Docking Module” on page 17 for details about the PDM.
Figure 2.3 The Docking Port
The docking port supplies DC power, a serial port, a USB host port, and a USB client port.
Power
Power for charging the batteries and powering the terminal (9-24 V DC; 3.4 A max) is supplied to the terminal through the docking port.
The terminal can supply 5V power (2 A max) to an external device through the
‘Power Output’ pins. This power is switched; the switch is controlled by the
Docking Port Services driver and is turned on only after the device is attached and a valid Dock ID is detected.
Console Port
The console port uses a standard 3 wire serial interface (TxD, RxD, GND). Signals levels are standard RS232 levels. This port is provided as a 9-pin D-connector on the Portable Docking Module.
This console port is multiplexed between the main processor (the default) and the peripheral controller. This console port is COM3 under Windows CE .NET.
USB Host Port
The USB host interface complies with USB specification 1.1 and provides a “highspeed” connection to external devices and hubs. Power for external devices is provided through the docking port’s power output pins. The OHCI driver is in charge of the USB Host interface.
14 7535 Hardware Reference Guide
Chapter 2: The Hardware
The Tether Port
USB Client Port
The docking port provides a USB client interface to connect the 7535 to a USB host computer or hub. The 7535 acts as a USB serial device via the USB client port. On the 7535, this serial device is COM4. The 7535 also can act as a USB client (a Mass
Storage Device), when its bootloader is running, to allow software updates via USB.
Dock ID
By reading a resistance value, the 7535 can identify the device attached to the docking port. The Docking Services driver reads the ID, identifying the device, checks the registry to see which driver to load, then loads the appropriate driver.
2.9.2 The Tether Port
The Tether Port
Figure 2.4 The Tether Port
The tether port allows an external non-decoded scanner, a serial scanner, or a USB client device to be connected to the terminal through a single connector. Generic serial devices, such as printers, GPS receivers, and other serial devices, are also supported.
The tether port is COM1.
The 7535’s peripheral controller identifies connected devices by sensing a resistor within the cable of the connected device. It notifies a driver running on the main processor that a device has been connected. This driver then looks for an appropriate driver to load, and instructs the peripheral controller to configure the port appropriately and enable power to the port.

Chapter 3: The Software
Overview Of The 7535’s Software
3.1 Overview Of The 7535’s Software
This chapter describes features of the boot process and operating-system software that are specific to the 7535.
The 7535 uses a custom build of Microsoft’s Windows CE.NET 4.2, with OS-native device drivers for its custom hardware. It can accept executables written for the Intel
X-Scale PXA255 processor, or (with the appropriate runtime engine) .NET CIL executables or Java bytecode executables.
The Psion Teklogix-developed ‘BooSt’ bootloader and mini-OS is used to perform initial hardware configuration and load system software.
The system software design supports the services required by applications. The operating system environment and standard development tools provide the standard services; an application may interface with Psion Teklogix’ custom hardware and software interfaces via the Psion Teklogix Mobile Devices SDK.
3.2 The Boot Process
3.2.1 Overview
The 7535 handheld terminal has both a main processor and a peripheral controller.
When the terminal is booted, the peripheral controller boots into BooSt, then runs its own software. This software is stored in the peripheral controller’s onboard flash memory.
The main processor uses BooSt as a bootloader and Windows CE .NET 4.2 as the primary operating system.
The image for the main processor’s software, including BooSt and Windows CE
.NET, are stored in the terminal’s flash memory. The main processor cannot boot directly from the flash; a more complex boot process is required. The peripheral controller loads a small amount of code into the main processor’s instruction cache, enabling it to start its own boot loader.
3.2.2 Boot Types
The boot process is the series of steps between pressing the on key on the 7535 to when the main operating system is ready for user input. There are three possible times that this may happen:
7535 Hardware Reference Guide 29
Chapter 3: The Software
Boot Types
• the first time the terminal is turned on at the factory (‘initial software load’)
• the terminal is turned on after it is powered down (‘cold boot’)
• the terminal is turned on after it was suspended (‘resume from suspend’).
The most common type of boot is the resume from suspend. When the 7535 is turned off, it enters a ‘suspended’ state, where its main processor is stopped, but retains the contents of its RAM.
Cold boot only occurs if the terminal is intentionally rebooted or if both the main battery and the backup super-capacitor become fully discharged.
The first-time software load, as the name suggests, only happens once, at the factory, and is not discussed further here.
On a cold boot or resume from suspend, the peripheral controller boots using the bootloader image in its flash.
Note: The following descriptions assume no errors during the boot process.
3.2.2.1
Cold Boot
During a cold boot, the peripheral controller is the first device powered up. It performs the following steps:
1. Boots the bootloader image located in its own flash.
2. Turns on an LED to confirm the button press by the user.
3. Powers up the main processor but leaves it in reset.
4. Initializes the main processor.
5. Continues running its own software.
Once out of reset, the main processor performs the following tasks:
6. Initializes the 7535’s SDRAM and flash memory.
7. Loads its copy of the bootloader from the NAND flash into RAM.
8. Communicates back to the peripheral controller that everything is okay.
9. Jumps to the bootloader.
30 7535 Hardware Reference Guide
Chapter 3: The Software
Other Power Transitions
The bootloader performs minimal initialization and waits until it gets a ‘Go’ message back from the peripheral controller, after which it:
10. Fully initializes itself.
11. Writes a message on the terminal screen and the console port.
12. Loads the OS image into RAM.
13. Runs the OS image.
While the Windows CE image is being loaded into RAM, a splash screen is displayed on the terminal’s display.
A cold boot can also be triggered by selecting Blue + 0 to get the start menu, then selecting Shut Down, Cold Reset.
3.2.2.2
Warm Boot
The warm boot is a complete cycle transition from Run to Suspend to Run. When transitioning from Run to Suspend, all applications are closed, but working RAM is not cleared and the file system is preserved. A warm boot resumes with working
RAM and a file system, whose contents have been preserved from a previous session.
A warm boot can be triggered by selecting Blue + 0 to get the start menu, then selecting Shut Down, Warm Reset.
3.2.3 Other Power Transitions
3.2.3.1
Suspend
A transition to the Suspend state (stopping the microprocessor) occurs when:
• There is a timeout of the user-input inactivity timer, or
• External power is removed, and the battery is low.
Suspend is the usual state of the terminal when it is ‘turned off’. It can be triggered by the user in two ways:
• by pressing Blue + 0 to get the start menu, then selecting Shut Down,
Suspend.
7535 Hardware Reference Guide 31
Chapter 3: The Software
User Interface
• by pressing the OFF key-combination Blue + Enter.
If the unit is running on battery power, and the remaining battery power drops to critical levels as reported by the battery pack, the system will transition gracefully to the Suspend state, and no data will be lost.
If the unit is running on external power without a battery installed, and external power is removed, the system will make a ‘non-graceful’ transition to the Suspend state. The object store is preserved, the file system in flash is intact, but registry changes that have not been stored in the registry files in flash are lost, running applications are lost, unsaved data is lost. Restart from this state is a cold boot.
3.2.3.2
Resume
During a Resume transition from the Suspend state, the boot process starts in the same way as a cold boot. When going into Suspend, the main operating system writes a value into the Power Management Scratch Pad register. This value can be
“run the main operating system on resume” or “run the boot loader on resume”.
When a value is read from this register on resume that corresponds to the value for
“run the main operating system on resume”, the bootloader jumps to the OS image in RAM, and the boot continues. If the value read corresponds to the value “run the boot loader on resume”, the bootloader continues to run, giving the user a command prompt.
The user can go to the bootloader’s command prompt manually by:
• pressing and holding the Scan, Blue, and Enter keys simultaneously for 6 seconds
• selecting Blue + 0 to get the start menu, then selecting Shut Down,
Bootloader.
3.2.4 User Interface
During the boot process, indicators let the user know what is happening:
• When the user presses the ON button, the four LEDs turn on momentarily to confirm the button press.
• When the bootloader is loaded and running on the main processor, a message is displayed on the terminal’s screen and on the console port.
32 7535 Hardware Reference Guide
Chapter 3: The Software
User Interface
• When the main operating system is loaded and run, a splash screen is displayed on the terminal’s screen.
• At the end of the boot process, the 7535’s shell is displayed on the screen.
Status messages are written to the 7535’s serial console ports during the boot process. The peripheral controller and the main processor console ports are multiplexed on the same physical port. They use different command prompts to let the user know which processor is displaying the status message.
The peripheral controller can display the following messages on the console port:
• Starting BooSt
• No image in the NAND flash
• No/Invalid image on CF card
• PXA250 jumping to BooSt
The main processor (the PXA250) can display the following messages on the console port:
• Starting BooSt
• Recovering from sleep
• PXA250 jumping to Windows CE
• Going to BooSt prompt
• Valid image in flash date code = <date code>
• Invalid image in flash
• Valid image on CF card date code = <date code>
• Invalid image on CF card
The user has also been given the ability to adjust when certain transition times are affected. This is done using the Power Properties applet in the Windows Control
Panel. One of two power schemes, ‘AC Power’ or ‘Battery Power’ can be chosen.
The following options can be changed by the user:
• Switch To Suspend
This is the amount of time the unit is idle before the unit executes the Runto-Suspend transition. This setting is on the Schemes tab of the Power Prop-
erties dialog. Possible settings are: Never, 1, 2, 3, 4, 5, 10, and 30 minutes.
7535 Hardware Reference Guide 33
Chapter 3: The Software
The Shell
• Suspend Threshold
This is the percentage of battery charge left when the unit executes the Runto-Suspend transition. This setting is on the Suspend Threshold tab of the
Power Properties dialog. Possible settings are: 0 to 50 percent, in 5% steps.
3.3 The Shell
3.3.1 Overview
The shell is responsible for providing an interface to the user for access to the terminal’s applications, files, and configuration. It also monitors and provides notifications to the user about the system state.
3.3.2 System Structure
The shell is the first user application run by the system. It registers several windows with the operating system and has several responsibilities defined by the OS. These responsibilities include monitoring system memory and power levels. Along with the tasks that are required by the OS, the shell is responsible for providing the user with usability features. These features include a notification area, a window that displays currently running tasks and a method to run applications.
The shell is a multithreaded application. Information is passed between the threads using Windows CE graphical window and event system (GWES) and shell-defined message types. Certain parts of the shell must register with the OS to receive special messages.
3.3.2.1
The System Monitor
The system monitor task contains one window to receive messages and can potentially be multithreaded. Each thread can be used to monitor a system resource. The initial design has only one thread that monitors system memory and power. This thread is woken up periodically and checks the system resources.
34 7535 Hardware Reference Guide
Chapter 3: The Software
System Structure
Memory Monitoring
When the free memory drops below a configurable limit, the shell sends a ‘hibernate’ message to the last used application window. Application windows are supposed to reduce their memory consumption when they receive this message. If the free memory situation has not improved, the system monitor will send hibernate messages to the other windows.
Power Monitoring
The power monitor provides two different means of feedback to the user.
The first method of feedback is a battery-gauge icon in the system tray. This icon, which resembles a battery, shows the level of charge left in the main battery.
When the battery is fully charged the icon is completely green, when the battery is completely discharged, the battery is red. The other levels in between vary in the amount of green and red in the battery icon (for example, at 60% charge level the battery is 3/5 green and 2/5 red). The shades of red and green will be chosen so that they display as light and dark on a monochrome display.
The battery-gauge icon is replaced with a icon displaying a power connector when the terminal is connected to external power and is not charging. It is replaced with an icon displaying a battery with a lighting bolt when the terminal is connected to external power and the battery is being charged.
The second method of feedback is the display of popup messages when the main battery level drops below a certain limit or the battery life has been exceeded.
Security Monitoring
The system monitor thread is also responsible for the current security level on the terminal.
The terminal has three security levels: User, Teklogix, and Supervisor. The system monitor task monitors the security level and will display an icon in the system tray if the terminal is in the Teklogix or Supervisor level. Any application that needs to set or get the current security level should do it through a shell API that will be handled by the system monitor task.

3.3.2.2
The Desktop
Desktop
System Tray
Task Bar
The desktop provides the user with a starting point to access the terminal’s file system (through a link to Windows Explorer), and configuration (through a link to the Control Panel).
The user may also put any applications or files in the
\Windows\desktop
folder and they will be displayed on the desktop. This gives the user quick and easy access to files and applications they might use frequently.
Important: This folder resides in RAM, and its contents will be lost during a cold boot.
The desktop window is also implicitly registered with the OS by naming itself
‘DesktopExplorerWindow’. The OS uses it to hide applications. Because Windows
CE does not support true minimization, any minimized windows are just placed behind the desktop.
The Taskbar
The taskbar is a window drawn across the bottom of the terminal’s screen. The taskbar has its own thread, and runs its own window, the system tray window, and the task manager dialog box.
36 7535 Hardware Reference Guide
Chapter 3: The Software
System Structure
The taskbar registers itself with the OS. The OS sends the taskbar two kinds of special messages:
• application creation and destruction events.
• certain key presses and key sequences.
Application creation and destruction events can be used for displaying buttons on the taskbar for running applications.
Key presses and key sequences can be used by the shell for any purpose.
The taskbar displays the Task Manager on receiving Alt + Esc, cycles running application windows on receiving Alt + Tab; and it displays the start menu on receiving a Menu (Blue + 0) key press. This start menu can be used to access certain shell features.
The taskbar is also responsible for displaying the start menu when the Menu key combination is pressed.
The System Tray
The system tray is a window within the taskbar. It registers a callback with the OS.
Once registered the OS will forward messages sent by applications to display notification icons (
Shell_NotifyIcon()
) to the system tray.
The system tray task processes these messages and draws the notification icons in the system tray window. The system tray also forwards any mouse or touch events on the icons back to the window that registered them. The system tray also displays the current time in its window when configured to do so.
7535 Hardware Reference Guide 37
Chapter 3: The Software
System Structure
The Task Manager
The task manager is a dialog box that is created on startup but is only displayed when the user requests it (by pressing Blue + 0, then T, or by pressing Alt + Esc, or by selecting Start Menu, Task Manager). When it is displayed, it lists the currently running applications. It allows the user to start a new application, close a running application, or bring a running application to the foreground.
When attempting to close an application, the task manager sends it a close message.
If the application does not close, the task manager checks to make sure they can close this application and ask the user if they really want to kill it. If the user answers yes, the task manager kills the application’s process.
3.3.2.3
The User Interface
The desktop contains icons for shortcuts to the most commonly access files and folders. At the bottom of the desktop is the taskbar. On the right side of the taskbar is the system tray. The system tray window does not have an outline but is only as tall as the taskbar and as wide as the icons it is displaying. The taskbar and the system tray can be configured to display on any edge of the screen.

Differences
The customized Psion Teklogix shell is an enhanced version of the Handheld PC
(HPC) shell, which is similar to the shell on the desktop version of Windows. There are some modifications to account for differences between the typical HPC and the
7535’s screen size and requirements. The major differences between the HPC shell and Psion Teklogix’ shell on the 7535 are:
• The HPC shell is optimized for 480x240 pixel displays, while Psion Teklogix’ shell is optimized for both 240x320 and 320x240 displays.
• The HPC shell has a 26-pixel taskbar, Psion Teklogix’ shell reduces this to
18-pixels to maximize the desktop (work) area.
• Psion Teklogix’ shell does not have a start button. Any important links should be on the desktop.
• Psion Teklogix’ shell does not have tabs on the taskbar for the running applications.
• Psion Teklogix’ shell uses the Menu key-combination (Blue + 0) to display a start menu with shortcuts to frequently used features.
3.3.2.7
Error Messages
The shell uses the Windows CE standard error messaging system to display major errors and uses on screen message boxes to display runtime errors.
3.4 Power Management
The Power Manager acts as a mediator between devices, applications, and defined
OS power states. It implements the following set of rules for facilitating communication between those three parties:
• OS power states impose maximum power consumption limits on all devices.
• Applications impose minimum power consumption limits on specific devices to obtain minimum performance levels.
• The Power Manager allows devices to intelligently manage their own power as long as they keep their power levels between the maximum and minimum limits.
40 7535 Hardware Reference Guide
Chapter 3: The Software
The Filesystem
• If the minimum power consumption limit is set higher than the maximum, the power of the device will remain elevated for as long as the application requires the device.
• If the OS transitions to a suspended power state, application-imposed minimum power limits will be set aside while the OS is suspended.
3.5 The Filesystem
The filesystem of the 7535 appears as one unified space. However it is composed of several different types of memory: internal RAM, internal flash, and installed memory cards.
When the 7535 cold-boots, the bootloader installs the operating system into RAM.
The resulting filesystem—the
\Windows
,
\Program Files
,
\My Documents
directories and so on—resides in RAM, and is cleared during a cold boot.
Note: In normal usage, the 7535 is not cold-booted. Unlike many computers, the unit is merely suspended when it is not in use, and the RAM retains its contents.
The 7535’s internal nonvolatile flash memory and any available memory cards are made available to this filesystem. That part of the 7535’s internal flash memory available to the user appears as the
\Flash Disk folder. Each partition on a memory card appears as a separate folder under the root folder. (Most memory cards have one partition by default; this can be changed through the Storage Manager.)
Memory-card folders are named as follows:.
Type Of Card Name Of First Or Only Partition
SD Card or
MMC
Compact Flash card
\SD-MMC Card
\CF Card
Name of Second And Later
Partitions
\SD-MMC Card2
,
\SD-MMC Card3
...
\CF Card2
,
\CF Card3
...
3.6 Locations Of Applications
Applications may be located in several places in the 7535.
7535 Hardware Reference Guide 41
Chapter 3: The Software
Locations Of Applications
An application can be installed either to RAM or to flash memory. If the application is installed to RAM, it is completely lost when the unit is cold-booted.
The default directory for files installed through ActiveSync’s Application Manager is
\Program Files\<appname>
, where
<appname>
is the name of the program. On the 7535, this directory resides in RAM and will be lost during a cold or warm boot.
The application may be installed into flash, but only if the application can be run from some folder other than the
\Windows
folder, which is not placed in the flash file system.
If the application is installed into the 7535’s internal flash memory in the folder
\Flash Disk
, the application will remain in the 7535, even after a cold or warm boot.
Application executables placed in
\Flash Disk\Startup
will be automatically started when the operating system starts after a cold boot. This will not happen after a resume from suspend.
Applications may be placed as
.cab
files in
\Flash Disk\Startup
. When the
7535 cold-boots, it will automatically install any
.cab
files located in this folder.
Applications may also be placed in memory cards.

Chapter 4: Connecting
Overview
4.1 Overview
This chapter provides connection information specific to the 7535, for connecting to the device through the following methods:
•
USB serial link. See section 4.2 on page 46.
•
Bluetooth short-range wireless link. See section 4.3 on page 48.
The ActiveSync software from Microsoft can be used to establish communication with the device, once the physical connection has been made.
Once an ActiveSync connection has been made over a USB serial link, ActiveSync can be used over a wireless connection such as Bluetooth. Software can then be deployed as described in the Developers’ Guide.
4.1.1 Setting Up ActiveSync
ActiveSync allows you to connect the 7535 to a PC through USB or Bluetooth communication. File transfers, file synchronization and sending e-mail can all be done via ActiveSync.
Important: ActiveSync must be connected and synchronized, and a ‘Partnership’ set up, through USB at least once before other connection types are possible.
Install the most recent version of ActiveSync on your PC (check the Microsoft website for the latest software).
Connection Types
There are two types of connection provided for by ActiveSync:
• Guest - A guest connection allows file transfers. No synchronization is performed. If the 7535 is password protected, the password prompt will appear when connecting as guest.
• Partnership - A partnership connection allows for synchronization of files, e-mail and other data. If the 7535 is password protected, a password prompt will appear before allowing synchronization.
You can disconnect any ActiveSync connection by double-clicking on the blue icon in the 7535’s system tray and selecting the Disconnect button from the dialog.
7535 Hardware Reference Guide 45
Chapter 4: Connecting
USB Serial Connections
Double-click the PC Connection icon in the Control Panel. The PC Connection
Properties dialog appears. Verify that the checkbox that allows connection to the desktop is checked:
“Connect Using” specifies the port to be used for connecting to the PC:
• USB specifies using the USB Type-B (client) port of the 7535. This port is provided on the Portable Docking Module.
• Bluetooth specifies using the internal Bluetooth connection of the 7535 (if present). This connection may have a different name.
To change the connection type, click on the Change Connection... button and select the connection from the dropdown list.
4.2 USB Serial Connections
The USB architecture defines a “host” device that can communicate with up to 127 client devices through a serial connection. When the host device powers up, it queries the USB bus, identifying devices.
USB serial connections are available at a number of different data rates.
• “High speed” USB devices communicate at 480 Mb/s.
• “Full speed” USB devices communicate at 12 Mb/s.
• “Low speed” USB devices communicate at 1.5 Mb/s.
USB devices may be self-powered, or powered through the USB cable.
46 7535 Hardware Reference Guide
Chapter 4: Connecting
USB Serial Connections
Any device that draws less than 100 mA from the USB cable is called a “low-powered” device; this includes self-powered devices that need no power, as well as devices such as tablets and mice that need little power.
Devices that draw more than 100 mA from the USB cable are called “high-powered” devices. The USB cable must be connected to another device that can supply this power.
The 7535’s Portable Docking Module is not rated to supply power to high-powered
USB devices.
USB cables can have two types of connectors. The ‘type-A’ connectors, found on USB host devices such as desktop computers, are wide and flat. The ‘type-B’ connectors, found on peripherals, are narrower and squarer.
USB cable lengths are limited. Full-speed cables are a maximum of 5 m long.
To connect using ActiveSync via USB:
1. Connect the USB cable to the USB type-A port on your computer.
2. Connect the other end of the USB cable to the 7535’s USB type-B port.
This port is the square connector on the left side of the Portable
Docking Module (labelled with the symbol).

4.3 Bluetooth Wireless Connections
Bluetooth wireless connections use a short-range wireless link to implement peerto-peer “piconets” of up to seven devices.
Each device on the piconet is identified by a three-digit MAC. An individual device can be a member of more than one piconet. Different piconets are distinguished by different frequency-hopping codes. Bluetooth radios use FHSS in the unlicensed
2.4-GHz ISM band.
Bluetooth radios are divided into three power classes:
1
2
3
Power Class Maximum Output
100 mW
2.5 mW
1 mW
Power
(20 dBm)
(4 dBm)
(0 dBm)
Table 4.1 Bluetooth Power Classes
Bluetooth connections can run at up to 740 kb/s, with a range of up to 10 metres for classes 2 and 3, and 100 metres for class 1.
To connect using Bluetooth, you will need:
• A 7535 with an internal Bluetooth card.

Overview
Displaying The Datecode Of The Operating System
5.1 Overview
This section describes what you need to do to replace the operating system on your
7535.
The OS software image on a 7535 contains the Windows CE .NET operating system
(OS), the .NET runtime engine, and all the software included with the 7535. It may also include Open TekTerm (Psion Teklogix’ terminal emulator program), or the
Jeode Java Virtual Machine (JVM).
OS images are available from Psion Teklogix in several slightly-different variants:
• with the .NET runtime engine (part number 1000891x)
• with the .NET runtime engine and TekTerm (part number 1000973x)
• with the .NET runtime engine and the Jeode JVM (part number 1000892x) where x indicates the revision level, starting with A.
These variants may be distinguished as follows:
• The variant with TekTerm has the TekTerm icon on the desktop.
• The variant with the Java Virtual Machine has Jeode EVM in its Programs menu. (Press Blue + 0, then select Programs, to reach this menu.)
A Windows registry key is set corresponding to these variants. The key
HKEY_LOCAL_MACHINE\SOFTWARE\Teklogix\CurrentVersion\ImageContents is set to ‘
SDK Image
’, ‘
TekTerm Image
’ or ‘
Java Image
’, depending on the variant.
On rare occasions, it may be necessary to replace the 7535’s bootloader software or the software in its peripheral controller. Contact Psion Teklogix support for assis-
tance (see Appendix A: Support Services And Worldwide Offices for details).
5.1.1 Displaying The Datecode Of The Operating System
There are a few ways to display the datecode of the operating-system software in the
7535. The version of this software is reported as a date code from the day the software was built. The date code of the software image can be found using any of the following methods:
• When running the TekTerm program, press Ctrl + Alt + 0 to show Tek-
Term’s Display Menu. TekTerm displays the date code of the software.
7535 Hardware Reference Guide 55
