Technical Documentation
Introduction
RAE–2N is the 2nd generation communicator for GSM 900 network. Communicator extends the basic digital cellular phone with in–built data capabilities and
applications.
RAE –2 is a phase 2, class4 transceiver with 2W peak TX power.
The device has two user interfaces. The conventional phone interface on the
front cover. By opening the device the user can access the graphical user interface which can utilize the full communicator functionality.
General Information
Technical Summary
The Communicator is divided into two main domains: phone and personal digital assistant (PDA). Phone manages speech and data connections to GSM network. It also handles audio input and output. PDA runs all the applications (e.g.
calendar, contact database etc...) and utilizes the data connections made by
the phone.
The phone is based on DCT3 technology and CUI style user interface software. PDA uses AMD’s 486 CPU and GEOS operating system.
Battery technology is Li–ion.
The product has earpiece for conventional phone use but it also has an internal
handsfree speaker.
Connection to the other devices can be handled with 115kbps serial cable or
115kbps IR. Product is IrDA compatible.

General Information
The phone display is graphical, transflective FSTN LCD display. Display resolution is 84x48 pixels. The PDA display is graphical, transflective FSTN LCD display. Display resolution is 640x200 pixels and dot pitch is 0.17mm. Contrast is
good enough to show 16 gray scales.
Both LCD displays are backlit with EL–panel.
In addition to the fixed memory the product can use memory extension module,
MMC, to expand the user file system area. The MMC supports hot insertion.
NOTE: Due to the infrared data link the RAE–2 is officially specificed as :
CLASS 1 LASER PRODUCT.
See IEC 60825–1 specification 825–1; Labelling, 5.1 General 5.2 Class 1.
Product Selection
The product has only one design, however each user interface language version has its own product code. Some countries have e.g. English communicator
but manuals in the local language.

Structure
RAE–2Nx consists of three electrical sub–modules and several mechanical
parts. The structure is basically the same for all the language versions. The
only parts that are unique to each language version are located on the first hierarchy level of the product structure; namely PDA keyboard, Language software
and type label. All other parts and modules are language independent.

Functional Description
The Communicator comprises two functionally independent units: PDA and
CMT.
The PDA implements the communicator application platform.
The CMT implements the GSM transceiver and basic data functionality, both
transparent and non–transparent data. All UI functionality is combined into one
UI module (BS2) but both PDA and CMT control their respective UI independently.
The Functional units and the implementation differ slightly. Due to mechanical
reasons some components are placed into a different module than they functionally belong. E.g. audio components are placed into BS1 (PDA) module
even if they functionally belong to the CMT.

General Information
PDA Module
The PDA modules has its own power management chip, the Phaser. The
Phaser regulates the voltages for PDA components. It also controls PDA power–up/down procedure by providing POWERGOOD and RESET signals to
Scotty.
The PDA processor Scotty is an embedded 486 processor manufactured by
AMD. The Scotty contains a set of PC peripherals except a parallel port. It
also has some additional peripherals like LCD controller and MMC host controller which are not standard to PCs. CPU has a 8k cache.
The PDA interfaces the CMT with 115kbps serial bus (FBUS). It also provides
low frequency clock (32kHz) to CMT. PDA also can get information about CMT
state (on/off) and wake up CMT.
CMT Module
The CMT is based on DCT3 engine and it is functionally the same. Sleep clock
(32kHz) is received from PDA side.
Technical Documentation
All the audio components are controlled by CMT (COBBA). It PDA wishes to
play sounds those are first sent to CMT. Keyclicks and some system sounds
are exceptions and are played directly by PDA.

Power Distribution
All the digital circuitry modules use 2.8V nominal operating voltage. Power is
drawn from 1140mAh Li–Ion battery. Higher voltages are generated for LCD,
SIM and backlighting.
The diagram below describes the power distribution of the product.
General Information
Audio
The transceiver has two speakers; earpiece for the telephone interface and
handsfree (HF) speaker. Different kind of tones can be played through speakers. HF speaker is driven only by CMT module. The earpiece can be driven
either by the PDA or the CMT. The transceiver has one microphone connected
to the CMT module.
The speakers are used :

Software Specifications of Interfaces
CMT SW is based on HD943. This product program has added internal data
functionality and ECI message interface.
External Devices
External devices can be connected through serial cable (DLR–2) or IR. The
protocols used are:
Technical Documentation
IrOBEX (ir–connectivity),
UltraIR (DCT3 connectivity),
IrDA (PC–connectivity)
IrTranP (camera connectivity).
The PC connectivity uses a specific PCCOM protocol on top of the IrDA or seri-
al connection.
Interfaces Between Transceiver Processors
PDA and CMT processors interface through serial FBUS channel. On top of the
physical FBUS link two separate protocols are used. The Phonet protocol is
used to transport CMT related control information and data–frames. ”RBUS” is
used to transport ECI (External Control Interface) messages between PDA UI
and CMT.
Software–Hardware Interface
CMT sw/hw interface is the same as hd940 is using.
PDA software is running on AMD Elan SC450 processor. Operating frequency
is 33MHz.

Connectivity
The lowest level of HW/SW interface is handled by the BIOS which provides
some basic services for upper sw layers. E.g. read data from memory card.
Testmode is used by production and After Sales. It provides the interface to
test and program PDA and CMT modules.
DOS layer implements only a subset of DOS functions known from conventional PC. DOS is used mainly in testmode and to launch GEOS.
GEOS is the basic SW platform to all applications that user sees. It however
interfaces directly to some HW resources, like LCD display or serial ports, by
its own HW drivers.
Alignment
Both PDA and CMT modules require alignment. Alignment is done at module
level to modules BS8 and BS1. LCD temperature measurement can be done
only after the assembly of the product.
The following parameters are adjusted in CMT module (BS8): TX power, RSSI,
AFC ,TX I&Q, battery voltage and charging current.
PDA module (BS1) needs alignment of: battery voltage, LCD contrast voltage.
Alignment is software based. Predefined reference point measurements are
stored into EEPROM (CMT) or flash (PDA).

General Information
Flashing
Product requires two separate flash images for executable code: one for the
CMT and one for the PDA system. Language versions are held in separate
files.
CMT flashing uses partly the same equipment as other DCT3 family products.
PDA flashing can be done with JTAG (low level flashing) or WinTesla. WinTesla
flashing is recommended.
