1.4 7535 G2 Hardware Architecture

1.4.2 Overview

The 7535 G2’s main processor is the Intel PXA255, which is the second generation of the StrongArm processor (SA1110).

A smaller, low-power microcontroller, the “peripheral controller”, is used to control and monitor many aspects of the 7535 G2’s hardware, including controlling system power, communicating with the smart battery pack, handling communications with the keyboard controller, collecting raw non-decoded scanner input, monitoring temperature, light, and other sensors.

There are also two PIC microcontrollers; one in the keyboard assembly scans the matrix keyboard and controls the LEDs (see ), and the other drives the keyboard backlight.

1.4.3 Body Variants

The 7535 G2 may be ordered with or without a tether port, and with or without a handstrap or handgrip.

The handstrap and handgrip are also available as customer-installable options.

Part numbers for the assembled housings are as follows. These assemblies include window glass, keypads, beeper boards, and tether-port flexes:

1.4.4.1

Scanner Control Services

This top level software service is responsible for supporting a variety of Physical Scan Drivers (PSDs), 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).

1.4.4.2

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).

1.4.4.3

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 G2. The scanners will be connected to one of the serial ports and controlled by the main processor. 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.

1.4.4.4

Imaging Scanners

The 7535 G2 can support an imaging scanner; both internal and external imaging scanners are supported.

Psion Teklogix provides a driver for this scanner.

Only one internal scanner is installed in the 7535 G2, but a second hand-held scanner can be connected via the tether port. Internal scanners can be triggered from the trigger switch on the 7535 G2’s handgrip

(if present) or from the Scan button on the 7535 G2’s keyboard. External scanners can only be triggered from their own trigger switch.

1.4.5 The Display

The 7535 G2 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.

1.4.5.6

Touch Input

Touch input is an option for the 7535 G2’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.

1.4.11 Ports

The 7535 G2 has the following external ports:

• Docking port.

Connects to chargers and docking modules; provides USB and serial connections.

• Tether port.

Connects scanners and other cabled peripherals.

See Appendix B for detailed descriptions and pinouts.

1.4.11.12 The Docking Port

The docking port allows the terminal to be placed in a cradle that allows battery charging and connection to peripherals. 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 12 for details about the PDM.

Figure 1.3 The Docking Port

The docking port supplies DC power, a serial ‘console’ 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 (1.5 A max, 1A continuous) to an external device through the ‘Power Output’ pin. This power is switched; the switch is controlled by

10 Psion Teklogix 7535 G2 Hand-Held Computer Service Manual

Chapter 1: Introduction

Ports 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’ is a serial text-mode interface to the 7535 G2’s system. Commands can be issued to the 7535 G2’s bootloader software through this interface. The console port is shared by the 7535 G2’s main processor and its peripheral controller; when the main processor is active, it is connected to the console port by default. This console port is COM3 under Windows CE .NET.

The console port uses a standard 3-wire serial interface (TxD, RxD, GND). Signals levels are standard

RS-232 levels. This port is provided as a 9-pin D-connector on the Portable Docking Module.

USB Host Port

The USB host interface complies with USB specification 1.1 and provides a “high-speed” 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.

USB Client Port

The docking port provides a USB client interface to connect the 7535 G2 to a USB host computer or hub. The 7535 G2 acts as a USB serial device attached to COM4 for Windows CE.NET. The 7535 G2 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 G2 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.

1.4.11.13 The Tether Port

Tether Port

Figure 1.4 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.

Psion Teklogix 7535 G2 Hand-Held Computer Service Manual 11

Chapter 1: Introduction

Power Management

Tether ID

The 7535 G2 can identify a device connected to the tether port by sensing an identification resistor within the connected cable. It then configures the port appropriately for the device and enables power to the port.

See The Tether Port in Appendix B.

1.4.12 Power Management

The 7535 G2 is powered by a lithium-ion rechargeable battery pack. The 7535 G2 can be powered from external power when used with the AC adaptor. When the 7535 G2 is powered from the AC adaptor, it will also charge the battery pack.

An internal supercapacitor holds charge for up to ten minutes to preserve the contents of RAM while the

7535 G2’s battery is being changed.

1.5 The Portable Docking Module

The 7535 G2 can be connected to a Portable Docking Module (PDM). The model 7535 G2 terminal can be connected to the same model PDM as well.

Chapter 1: Introduction

The Portable Docking Module

The Portable Docking Module provides serial and USB ports. The PDM has the following ports:

• Serial port.

This 9-pin D-connector accepts a null-modem serial cable which connects to an external development machine.

• USB type B port.

This port accepts a cable from a USB host (typically the development machine).

• USB type A port.

This port connects the 7535 G2 to other devices; the 7535 G2 serves as a USB host.

• Docking port.

This port connects to the 7535 G2.

• DC power connector.

Accepts 15 V DC from the power adaptor.

The Portable Docking Module is available as part of a kit from Psion Teklogix. This kit, Psion Teklogix part number 1030085, includes the following items:

• The Portable Docking Module (part number 1030083-001).

• A USB A-B cable (part number 9003322).

• A null modem cable (part number 9003659).

• An AC-to-DC power adaptor (part number 9007558).

• A power cord. (North American power cord: part number 9008693).
