Restriction On Hazardous Substances (RoHS) Directive 2002/95/EC
What is RoHS?
The European Union has mandated that high environmental standards be met in the design and
manufacture of electronic and electrical products sold in Europe, to reduce hazardous substances
from entering the environment. The “Restriction on Hazardous Substances Directive (RoHS)” prescribes the maximum trace levels of lead, cadmium, mercury, hexavalent chromium, and flame
retardants PBB and PBDE that may be contained in a product. Only products meeting these high
environmental standards may be “placed on the market” in EU member states after July 1, 2006.
RoHS Logo
Although there is no legal requirement to mark RoHS-compliant products, Psion Teklogix Inc. indicates its compliance with the directive as follows:
The RoHS logo located either on the back of the product or underneath the battery in the battery
compartment (or on a related accessory such as the charger or docking station) signifies that the
product is RoHS-compliant as per the EU directive. Other than as noted below, a Psion Teklogix
product that does not have an accompanying RoHS logo signifies that it was placed on the EU
market prior to July 1, 2006, and is thereby exempt from the directive.
Note: Not all accessories or peripherals will have a RoHS logo due to physical space limitations
or as a result of their exempt status.
Disclaimer
Every effort has been made to make this material complete, accurate, and up-to-date. In additio n,
changes are periodically added to the information herein; these changes will be incorporated into
new editions of the publication.
Psion Teklogix Inc. reserves the right to make improvements and/or changes in the product(s)

Psion Teklogix WORKABOUT PRO HDK User Manual 19
3.1 Overview
This chapter describes the software aspects of controlling expansion modules for the
WORKABOUT PRO.
3.2 Windows Drivers
3.2.1 The Peripheral Control (PCO) Driver
Psion Teklogix provides the peripheral control driver (PCO), a driver for the 100-pin expansion
slot. The PCO driver is a Streams driver activated very early at boot up time (it is loaded after the
File devices driver and the I2C driver).
3.2.2 The PCMCIA Driver
Hardware containing a PCMCIA slot may be connected to the 100-pin expansion slot. The PCO
driver determines whether this PCMCIA socket is present and enabled, and controls the loading of
the PCMCIA driver.
The PCMCIA driver handles both the Compact Flash and the PCMCIA socket interfaces. Since
the PCMCIA socket is itself an expansion module, the PCO driver must identify this hardware
prior to activating the PCMCIA driver.
Non-Psion Teklogix d rivers may no t separately activate the PCMCIA socket. You may design interfaces using the PCMCIA memory specification and interface to the hardware using the
predefined PCMCIA memory windows.
Chapter 3: Software
Overview
3.2.3 The Serial Port Driver
The PCO driver also controls the loading of the full-function UART serial port driver.
3.3 Non-Psion Teklogix Drivers
The Psion Teklogix platform loads some standard device drivers. If the expansion module uses
standard drivers such as PCMCIA, serial, or USB, there is no need to load customized drivers. For
information on specifying a Psion Teklogix driv er see “Expansion Mod ule EEPROM Fields” on
page 75.
3.3.1 Installation
All non-Psion Teklogix drivers must be installed in permanent storage—not in RAM. This ensures
that the driver can be activated after a cold reset.
There must be a registry entry for the driver and its parameters. For details see “Registry Keys” on
page 22.
The name of the driver must be set in the Manufacturer/Model field in the expansion module
EEPROM. For details see “Expansion Module EEPROM Fields” on page 75.
3.3.2 Drivers In Windows Mobile 6
The files required for signing drivers in Windows Mobile 6 are included in the HDK pack age.
Psion Teklogix WORKABOUT PRO HDK User Manual 21
Chapter 3: Software
System Initialization
3.4 System Initialization
During system startup the following occur:
1. The expansion module EEPROM is initialized and read.
2. If a non-Psion Teklogix device driver is required, it is identified from the EEPROM data
and activated. For details of this process see “Loading Non-Psion Teklogix Device Drivers” on page 24.
3. The PCMCIA/Compact Flash card driver is activated if one of the following
conditions exists:
• The PCMCIA registry key is set. See “Registry Settings For Psion Teklogix Device Driv-
ers” on page 23.
•The Hardware type field in the expansion module EEPROM is set for a PCMCIA device.
See “Expansion Module EEPROM Fields” on page 75.
4. The full-function UART (FFUART) serial port driver is activated if one of the following
conditions exists:
• The FFUART registry key is set. See “Regis try Settings For Psion Teklogix Device Driv-
ers” on page 23.
•The Hardware type field in the expansion module EEPROM is set for a serial device. See
“Expansion Module EEPROM Fields” on page 75.
5. The USB hub is activated if one of the following conditions exists:
• The USB registry key is set. See “Registry Settings For Psion Teklogix Device Drivers” on
page 23.
•The Hardware type field in the expansion module EEPROM is set for a USB device . See
“Expansion Module EEPROM Fields” on page 75.
• A USB scanner is detected on the internal scanner port.
6. If a scanner is detected, the keyboard processor wakeup signals for the scan keys is set.

Psion Teklogix WORKABOUT PRO HDK User Manual 23
Chapter 3: Software
COM Port Assignments
Where: EEPROM is the name of the device driver. This is the contents of the
Manufacturer/Model field in the expansion module EEPROM. For details see “Expansion
Module EEPROM Fields” on page 75.
3.5.4.1 Loading Non-Psion Teklogix Device Drivers
At system startup the following process is used to load non-Psion Teklogix device drivers:
1. The contents of the Manufacturer/Model field in the expansion module EEPROM are
appended to the registry key
HKEY_LOCAL_MACHINE\Drivers\PsionTeklogix\Expansion Slot\
For example, if the Manufacture/Model field contains:
ACME gizmo
then the following driver is loaded:
HKEY_LOCAL_MACHINE\Drivers\PsionTeklogix\Expansion Slot\ACME gizmo
2. The DriverActivate() function uses this registry key to activate the driver.
No driver is loaded if:
•The Manufacturer/Model field is not valid, or it is empty.
• The derived registry key does not exist.
Note: If multiple device drivers are r equired for the same device, subkeys are defined. Only the
first driver is automatically activated. The application must load and activate all
additional device drivers.

3.7.4 The ExpansionWakeup Namespace
This namespace manages the wakeup from suspend signal on pin 79 of the 100-pin co nnector . The
wakeup can be enabled or disabled.
This signal is connected to the keyboard controller and is monitored from there. This pin wakes
the processor but does not generate a software-accessible interrupt.
3.7.5 The GPIO Namespace
This namespace is used to manage acce ss to the 100 -pin connecto r general purpose inpu t/output
(GPIO) pins. These pins are listed in “General-Purpose I/O” on page 71.
If a full PCMCIA interface is used, some pins are not available for GPIO. Thes e pins are identified
on Table 7.1 Pinout of the WORKABOUT PRO 100-Pin Connector on page 64.
3.7.6 The EEPROM Namespace
This namespace contains functions that access the expansion module EEPROM.
This namespace handles EEPROMS of up to 256 bytes only . Ac cessing EEPROMs larger than
this requires the use of the smBus namespace to communicate directly with the EEPROM. See
“The smBus Namespace” on page 27.
3.7.7 The ExpansionUSB Namespace
This namespace manages th e expansion USB power contro ls. The USB power co ntrol signal is
output on pin 88 of the 100-pin connector.
Expansion USB power can also be enabled by the USB registry setting and by setting an appropriate value in the Hardware type field in the expansion module EEPROM. Functions in this
26 Psion Teklogix WORKABOUT PRO HDK User Manual
namespace do not override these settings. For details see “Registry Settings For Psion Teklogix
Device Drivers” on page 23, and “Expansion Module EEPROM Fields” on page 75.
On the WORKABOUT PRO 2nd. Generation, the expansion USB is also available on the connector CN601 on the top of the unit. The 5 V power for this connector is also controlled by the USB
power API.
If the USB hub it is not already enabled, enabling the expansion USB also enables the USB hub.
Expansion USB power is power-managed and is automatically disabled on suspend and re-
enabled on resume (if it was previously enabled).
3.7.8 The USBhub Namespace
This namespace manages power to the USB hub.
3.7.9 The ScannerPort Namespace
This namespace is used to access the barcode scanner port if no internal scanner is detected.
If a built-in scanner is detected, it is managed by Scanner Control Services and the functions in
this namespace are not available. Application programs can access Scanner Control Services
through the Psion Teklogix Mo bile Devices SDK.
Chapter 3: Software
The USBhub Namespace
3.7.10 The smBus Namespace
This namespace is used to manage access to I2C devices on the smBus. The smBus interface functions do not guarantee delivery as the addressed device may not be connected to the I2C bus.
Functions return appropriate errors to indicate this.
For details of the I2C bus see “I2C Device Identification” on page 73.
3.7.11 The PCMCIA Namespace
This namespace is used to access PCMCIA bus functions, if a full PCMCIA function is not in use.
Details of the PCMCIA interface can be found in the Marvell PXA255 and PXA270
Developer Manuals.
These functions return errors if the PCMCIA socket is already in use. In this case, the standard
PCMCIA driver manages the memory windows.
The PCMCIA timing functions are processor specific and fail if called on the wrong platform.

34 Psion Teklogix WORKABOUT PRO HDK User Manual
4.4.2 Backplate-Mounted Device
The backplate-mounted device must fit within the backplate of the WORKABOUT PRO. It can
project inwards into the WORKABOUT PRO to a varying distance, depending on other options
installed within the WORKABOUT PRO.
The greatest amount of room is found within a WORKABOUT PRO that has no expansion
module installed. T o prevent interference with ex pansion cards, the backplate-mounted device, or
the backplate itself, must not protrude into the terminal plastic housing by more than 3 mm.
This HDK provides IGES models of the backplate, and of the bodies of the WORKABOUT PRO
variants. See the list of IGES files in “HDK Mechanical Files” on page 31.
Consult the 2D drawing of the backplate for the backplate hole locations.
To maintain sealing, and the IP rating, the sealing rib of the backplate must have a height of
0.60 mm and a width of 0.5 mm.
To maintain compliance with the WORKABOUT PRO drop test specification, backplates and
scanner devices must not weigh more than 90 g (0.2 lb) in total, the same weight as the SE1223
backplate/scanner module combination. The shape of the backplate influences the outcome of
drop testing.
4.4.3 Expansion Module
Chapter 4: Mechanical Considerations
Backplate-Mounted Device
Expansion modules must fit within the perimeter of the WORKABOUT PRO metal mounting
frame. They cannot exceed a height of 5.5 mm, as measured from the underside of the modu le
towards the display of the WORKABOUT PRO. The holes that connect the card stop must not be
covered.
Only the 100-pin connector should be placed on the under side of the expansion board. Other
components on the underside can interfere with the following:
• On the WORKABOUT PRO C, S, M, ME:
- the backup battery, or
- the CF card and socket.
• On the WORKABOUT PRO 2nd. Generation C, S:
- the SD card slot, or
- the CF card and socket.
In addition, it must be possible to insert the completed expansion card through the backplate
opening of the WORKABOUT PRO. This is especially important if the card is longer than the
backplate opening.
The HDK provides IGES models of the mounting frames for the WORKABOUT PRO variants.
An IGES model for a sample PCMCIA expansion module is also included. See the list of IGES
files in “HDK Mechanical Files” on page 31.

See “HDK Mechanical Files” on page 31 for a list of detailed drawing and IGES models for the
endcap assembly and all its parts as well as the IGES model of the WORKABOUT PRO bodie s.
The standard endcap is 83.35 mm long, 25.40 mm wide, and 23.87 mm deep. To maintain the ex-
isting drop test specifications, customized endcaps must not weigh more than 22 g (0.05 lb).
To maintain IP sealing, the endcap sealing rib must have a height and width of 0.8 mm. If the
stylus is to be used then it must be sealed against the stylus holder using the rubber stylus gasket.
The shape of the endcap influences the outcome of drop testing.
It is important that the correct card stop is fitted. It must fit into the internal frame and housing
with no interference to the endcap.
Consult the drawings for information on which card stops are used in each WORKABOUT PRO
variant, and which card stops are used with each card type.

Powering An Expansion Module
The power supply pins are:
• DC_IN (an external DC supply to the WORKABOUT PRO) (pins 97 and 99).
• V_IN (nominal 5 V DC supply to the expansion module) (pins 1, 2, 3, and 4).
• Ground (pins 21, 22, 39, 40, 57, 58, 77, 78, 84).
The DC_IN line can accept DC power of the following specific ation:.
Pin Name Nominal Voltage Tolerance Maximum Ripple Maximum Current
DC_IN 5 V 5% 50 mV 2100 mA
Psion Teklogix WORKABOUT PRO HDK User Manual 69
Chapter 7: 100-Pin Connector
Data And Address Buses
V_IN conforms to the following specifications:
Pin Name V oltage Minimum Voltage Maximum Maximum Current
V_IN 2.6 V 5 V 2000 mA
Hardware connected to the 100-pin expansion slot can be powered from the WORKABOUT
PRO, using V_IN. Return is through the ground pins.
When the WORKABOUT PRO is on external power, the battery power is not used.
When the WORKABOUT PRO is powered by an external adaptor, V_IN is at the adaptor supply
voltage minus a diode drop. The adaptor supplies 4.5 V to 5.5 V. After the diode drop, V_IN is
3.8 V to 4.8 V.
When the WORKABOUT PRO is powered by the battery, V_IN is at the battery voltage, which
ranges from 2.6 V to 4.2 V (nominal 3.7 V).
For information on the battery power and the battery threshold voltages, see “Batteries” on
page 16.
Powering The WORKABOUT PRO Through The 100-pin Connector
The WORKABOUT PRO can be powered from the 100-pin expansion connector as well, using
the DC_IN pins (pins 97 and 99) as a power input. These pins are connected to the same line as the
DC_IN input from the external adaptor.
Warning: Do not reverse the polarity of power supplied to the DC_IN input on the 100-pin
connector. Such reversal will damage the WORKABOUT PRO.
7.4 Data And Address Buses

Wakeup
If the Psion T eklogix PCMCIA driver is used, all of the d ual function pins (the gen eral-purpose
I/O and interrupt signals) that can be used by the PCMCIA interface will be reserved by the
PCMCIA driver. All of these pins con form to the pin fu nctions as defin ed by the PC Card Standard, Release 8.
A customized driver can be developed so that the dual function pins can be separated from the
PCMCIA interface. Psion Teklogix does not supply such a driver.
Memory devices and variable latency IO devices (such as ASICs and FPGAs) can be connected to
the PCMCIA interface. Timing of the interface is configurable. The nSLOT_WAIT_SRC signal
may used to extend the bus cycle.
The data bus, address bus, and control signals should be buffered in the expansion device to
prevent excessive loading. These traces should also be kept to the minimum possible length.
PCMCIA Interface Timing
The PCMCIA interface is fully compliant with the PCMCIA standard.
The PsionTeklogix::WORKABOUTPRO_HDK::PCMCIA namespace provides access to the
following registers so that the timing can be configured by a software application.

7.10 Wakeup
A wakeup input is available so that expansion devices can signal the WORKABOUT PRO. This
pin is:
• nSLOT_WAKEUP (pin 79).
This signals is at CMOS levels (0 V to 3.3 V).
This signal wakes the WORKABOUT PRO from its suspend state—it does not generate an inter-
rupt that can be detected by a software application. Connect the source to an expansion-slot
interrupt pin as well (InputPin63 or InputPin65), if an interrupt is also required.
7.11 I2C Device Identification
All expansion devices connected to the WORKABOUT PRO 100-pin expansion bus must contain
an I2C EEPROM. The expansion EEPROM is used to identify the hardware and to load appropriate drivers. This information is displayed on the Properties tab of the Control Panel
System program.
The 100-pin connector provides signals for an I2C bus:
• I2C_SDA (pin 98).
WORKABOUT PRO WORKABOUT PRO 2nd. Generation
Psion Teklogix WORKABOUT PRO HDK User Manual 73
Chapter 7: 100-Pin Connector
I2C Addresses
• I2C_SCL (pin 100).
These signals are at CMOS levels (0 V to 3.3 V).
This identifying EEPROM should be an I2C EEPROM of at least 128 bytes. Psion Teklogix rec-
ommends using a serial-access 1-kilobit (128 x 8) EEPROM, such as STMicroelectronics
ST24C01 or similar. Larger EEPROMs may be used. The address of the device must be set to
0x01 by connecting the A0 pin to the expansion module’s VCC and the A1 and A2 pins to ground.
An example of the circuit, as implemented on the sample Multi-I/O Expansion Module, is
shown below:
Figure 7.3 EEPROM Circuitry
In this circuit, to write protect the EEPROM use the jumper at SJ2 to connect the WP line to the
+3.3 V supply; to write enable the EEPROM use the jumper at SJ2 to connect the WP line
to ground.
See “I2C Device Identification” on page 73 for a description of the contents of this EEPROM.
Other I2C devices can also be connected to the I2C bus.

V+3.3 is the main 3.3 V system voltage of the WORKABOUT PRO, supplied ultimately from
V_IN via a DC-to-DC converter . V+3.3 remains powere d when the WORKAB OUT PRO
is suspended.
These voltages have the following specifications:
Table 8.2 Voltages Supplied To The Scanner Device
Supply Nominal Voltage Continuous Current
V+5_BAR 5 V 300 mA
V+3.3 3.3 V 150 mA
V_IN is a diode OR of V_BAT (the DC voltage supplied by the WORKABOUT PRO battery),
and DC_IN (the DC power input from the external AC-to-DC adaptor). V_IN feeds a DC-to-DC
converter; the output of the converter is switched by the scanner power enable signal, and is
known as V+5_BAR.
When the terminal is powered by an external adaptor, V_IN is at the supply voltage of the adaptor
minus a diode drop. The adaptor supplies 4.5 V to 5.5 V; after the diode drop, V_IN is 3.8 V to
4.8 V.
When the terminal is powered by the battery , V_IN is at the battery voltage, which ranges from
2.6 V to 4.2 V (nominal 3.7 V).
For details of battery threshold voltages see “Batteries” on page 16.

V+5_BAR is +5 V supplied from a DC-DC converter fed by V+5, the main 5 V supply of the
WORKABOUT PRO. It can be switched on and off by the 5VBAR_PWR_EN signal while the
WORKABOUT PRO is running, but is disabled when the WORKABOUT PRO is suspended.
V+3.3 is the main 3.3 V system voltage of the WORKABOUT PRO, supplied ultimately from
VIN via a DC-to-DC converter. V+3.3 remains powered when the WORKABOUT PRO
is suspended. In the WORKABOUT PRO 2nd. Generation, the 3.3V supply to the scanner connector is disabled when the WORKABOU T PRO is su spend ed.
These voltages have the following specifications:

Supply Nominal Voltage Continuous Cu rrent
V+5_BAR 5 V 300 mA
V+3.3 3.3 V 1 A
VIN is a diode OR of VBAT (the DC voltage supplied by the WORKABOUT PRO battery), and
DC_IN (the DC power input from the external AC-to-DC adaptor). VIN feeds a DC-to-DC converter; the output of the converter is switched by the scanner power enable signal, and is known as
V+5_BAR.
When the terminal is powered by an external adaptor, VIN is at the supply voltage of the adaptor
minus a diode drop. The adaptor supplies 4.5 V to 5.5 V; after the diode drop, VIN is 3.8 V to
4.8 V.
When the terminal is powered by the battery , VIN is at the battery vo ltage, which ranges from
2.6 V to 4.2 V (nominal 3.7 V).

8.7 Signals To The Scanner Device
The WORKABOUT PRO does not provide the data and address buses of its main processor (the
PXA255 or PXA270) to the scanner port. Instead, communication to the scanner is provided by
USB or serial lines.
All the serial signals are present to connect a decoded sc anner . A USB host p ort is also provided so
that USB peripherals can be connected via the scanner port.
These signals are at 3.3 V CMOS levels.
Serial scanner devices can be connected through the following signals on the
WORKABOUT PRO:
• IR_TXD (data to the scanner device, pin 3).
• IR_RXD (data from the scanner device, pin 5).
• nBAR_CTS (Clear To Send flow-control signal from the scanner device, pin 7).
• nBAR_R TS (Ready To Send flow-control signal to the scanner device, pin 9).
Serial scanner devices can be connected through the following signals on the WORKABOUT
PRO 2nd. Generation:
• BAR_TXD (data to the scanner device, pin 3).
• BAR_RXD (data from the scanner device, pin 5).

Signals T o The Scanner Device
• BAR_CTS (Clear To Send flow-control signal from the scanner device, pin 7).
• BAR_R TS (Ready To Send flow-control signal to the scanner device, pin 9).
The assignment for this port is COM 3. It cannot be reassigned.
USB scanner devices can communicate through the following bidirectional data signals:
• USB_H2_D+ (pin 6).
• USB_H2_D- (pin 4).
Note: There is no USB power-enab le signal on the scanner po rt.
In the WORKABOUT PRO 2nd. Generation, the 5V supply (V+5_BAR) is controlled
by 5VBAR_PWR_EN.
In addition, there are control signals for both USB and serial scanner devices:
• BAR_PWRDWN (pin 16).
• nBAR_WKUP (pin 18).
• nBAR_TRIG (pin 20).
BAR_PWRDWN is an input to the main logic board. The scanner device can use this signal to
inform the WORKABOUT PRO that it has shut down. Pull this signal high to enable it.
nBAR_WKUP and nBAR_TRIG are outputs from the main logic board. Their operation varies
depending on the design of the scanner device and the device driver.
A pair of lines from the WORKABOUT PRO keyboard matrix are also provided:
• Input on pin 13.
• Output on pin 15.
Short these signals together for a minimum of 20 milliseconds to initiate a scan or to wake up the
WORKABOUT PRO.
Note: nBAR_CTS and nBAR_RTS —BAR_CTS and BAR_RTS on the WORKABOUT PRO 2nd.
Generation—are not hardware flow-control sig nals. CTS mu st be po lled by software, and
RTS has to be set / cleared by software.
Apart from V+5_BAR, th e signals conn ected to the scanner port are at 3.3 V CMOS levels. Use a level translator before the scanner cable to co nnect 5 V signals to the
WORKABOUT PRO main logic board.
