Introduction

The HSE–6XA Handset has two main functions: to form an

electro–acoustic interface between the user and the transceiver unit and

to provide means for controlling the transceiver unit and other

accessories.

The HSE–6XA is divided into two parts: the EH9 electronics module and

the MHSE6XA mechanics. The EH9 module consists of an 8–bit

microprocessor with internal memory, a 2x8 character display (+ 2

seven–segment) with one driver IC, keyboard, earphone, microphone,

loudspeaker and corresponding amplifiers.

The mechanics consist of the A–cover (front), B–cover (rear), keyboard

rubber mat, coiled cord, display frame and a number of smaller parts.

The HSE–6XA is designed for single–handset systems and for mobile use

only, so it has no audio switches, and is not provided with functions for a

power–safe or sleep mode.

Handset HSE - 6XA

Technical Summary

Modes of Operation

The HSE–6XA has only one mode of operation, used when the handset is

operating as a combined handset and control unit. There is no need for a

local mode because all testing can be done by means of

M2BUS–messages.

External Signals and Connections

The HSE–6XA has an 8–pin connector for connection to the junction box,

system cable and transceiver via coiled cord.

Keyboard illumination is accomplished with LEDs and is switched on, off
or dimmed by the microprocessor.

The Display controller/driver is connected to the microprocessor over a
parallel data line, and contains a display data RAM and character
generator ROM/RAM.

The Voltage converter converts the voltages of +5 V to –5 V and divides
the voltage between +5 V and –5 V to five levels (V1...V5), which are
connected to the display controller/driver.

The LCD display is connected to pcb and display drivers over two
elastomer connectors.

The Display illumination is of the same type as the keyboard illumination.

Circuit Description

General

The user interface of the handset is of the menu type. Alphabetical
characters can be used. A dot matrix display is provided.

Construction

The handset consists of two body halves with a PC board inserted in
between. A coiled cord, a speaker, an earphone and a microphone are
wired to the PC board.

Handset Module

The HSE–6XA handsets consist of the following functional blocks:

1. microphone amplifier

2. earphone amplifier

3. CPU with peripherals

4. Hook indicator

5. M2BUS electronics

11. power on/off logic

12. oscillators

Microphone Amplifier

The microphone is biased through the RC filter R135,C37,C65 and source
resistor R49.

The frequency response of the microphone is filtered to obtain a suitable
shape by low pass filters C10/R60 and R10/R11/C11/C12/C14/R8 and
high pass filter R9/C13. The amplification is about 29 dB with a 1 kHz
signal. The microphone amplifier is built around OPAMP N3 (pin 5,6,7).

Earphone Amplifier

The Earphone amplifier is of the differential type. Total amplification is
about 10 dB. The reference voltage is 4.0 volts. The earphone amplifier is
built around OPAMP N3 (pin 1,2,3 and pin 12,13,14)

CPU with Peripherals

Microprocessor D1 is a single chip version with internal ROM and RAM. It
has 16 kbytes of ROM and 256 bytes of RAM. It controls the other blocks
on the basis of information coming from the M2BUS. In addition, it reads
the user inputs, and sends them to the M2BUS.

HOOK Indicator

On–hook/off–hook information is received from a reed relay, which is
located on the PC board and controlled by a magnet in the handset
cradle.

M2BUS Electronics

Technical Documentation

The MBUS is a serial data bus with which the handset sends messages
to, and receives them from, the radio unit. Transistor V28 sends the
outgoing messages (TXD). Incoming data comes to processor pin 11
(RXD). Net free state is controlled by software before message sending.

LCD Display

The display is a 16 symbol 5 x 7 dot matrix supertwist LCD with two
7–segment characters and a few indicators. The LCD is connected to the
PCB by two elastomer connectors. The multiplexing ratio is 1:16.

Display Controller/Driver

The Display controller/driver is connected to the microprocessor by a
parallel (4 bit) data line, and contains display data RAM and character
generator ROM/RAM. All other characters are created by the processor
ROM. There is reserved a memory location for one character in RAM,
loaded by a M2BUS message.

Resistors R35, R42 and R88 comprise a resistor network from which the
LCD driving voltages are received. The voltage between +5 V and – 5 V is
divided to five levels which are applied to the display driver. R41 provides
temperature compensation (about 10 mV/ °C).

Keyboard Matrix

Keyboard has a 3 x 8 line matrix. Four of the eight write lines are used in
common with display driver data lines. A diode in each of these lines
prevents any contention in data lines when two or more keys are
depressed at the same time.

Illumination

The keyboard and the display are illuminated by LEDs. They can all be
switched on or off. Furthermore the display LEDs have 3 dimmer levels.
The on/off and dimmer function is controlled by the microprocessor.
Variations in power supply voltage (10.8V to 15.6V) do not affect
illumination as all LEDs are powered by constant current sources.

The keyboard is lit by 22 LEDs. There is one illumination LED for each
button.

The display is lit by six LEDs V9...V14 (three in series). The LEDs are
located on the PC board at the ends of the plastic display light conductor.
The light conductor is beneath the display.

Handset HSE - 6XA

Voltage Supply

The handset receives the battery voltage of the radio unit (about 12 V).
This voltage is fed to the LEDs and the voltage regulators. There is an
eight volt regulator N3 for audio circuits and a five volt regulator, N4, for
the logic.

The analog 8V supply is divided to 4.0 volt by resistors R3 and R4 and
buffered by op.amp. N3 (pin 8,9,10) connected as a voltage follower to get
the reference voltage for the audio amplifiers.

The negative five volt supply for the display driver is created by diode V29
and capacitors C17 and C24. The drive frequency is produced and
buffered by inverter D3.

To avoid audio disturbances, ground potentials are separated between the
analog and digital parts. AGND is the analog ground where the ground
current is almost zero. DGND is the ground for the digital circuits and
circuits which use more power, such as LEDs.

Power on/off Logic

The power on/off switch is located on the keyboard (but not in the matrix).
The radio unit detects the depression of the power button and turns power
on. When the button is pressed while power is on, the microcontroller of
the handset detects it and sends a M2BUS message to the radio unit. The
radio unit detects the duration of the key depression; if it is more than 0.5
seconds it will turn power off.

Handset HSE - 6XA

Oscillators

The clock frequency of 7.3728 MHz for the microcontroller is generated by
crystal oscillator B4. In order to decreae harmonic frequencies resistor R2
and capacitor C32 are added.

The oscillator for the display driver and the negative five volt generator
comprises inverter D3, resistors R33 and R34 and capacitor C47. The
frequency is about 200 kHz.
