THEORY OF OPERATION
1.0 Introduction
This Chapter provides a detailed theory of operation for the Controlhead circuits. For details of the
trouble shooting refer to the related chapter in this section.
2.0 Controlhead Model for CM140 and CM340
The controlhead contains the internal speaker, the on/off/volume knob, the microphone connector,
several buttons to operate the radio and three indicator Light Emitting Diodes (LED) to inform the
user about the radio status and a 7-segment display for numeric information.
2.1 Power Supplies
The power supply to the control head is taken from the host radio’s 9.3V via connector J803-9, The
9.3V is used for the LEDs and back light, the 5V is used for the LCD driver and level shifter. The
stabilized 3V is used for the other parts.
2.2 SPI Interface
The host radio (master) communicates with the control head through its SPI bus. Three lines are
connected to the shift register (U801):SPI clock (J803-17), SPI MOSI (J803-16) and shift register
chip select (J803-15).

2-2 THEORY OF OPERATION
When the host radio needs to send date to the shift register, the radio asserts the shift register chip
select and the data is loaded to the shift register. For example, the host radio sends data to change
display channel or change LED status.
2.3 Keypad Keys
The control head keypad is a four-key design. All keys are configured as two analog lines read by
µP. The voltage on the analog lines varies between 0V and 3.3 V depending on which key is
pressed. If no key is pressed, the voltage at both lines is 3.3V. The key configuration can be thought
of as a matrix where the two lines represent one row and one column. Each line is connected to a
resistive divider powered by 3.3V. If a button is pressed, it will connect one specific resistor of each
divider line to ground level and thereby reduce the voltages on the analog lines. The voltages of the
lines are A/D converted inside the µP (ports PE 6 - 7) and specify the pressed button. To determine
which key is pressed, the voltage of both lines must be considered.
The same analog lines also support a keypad microphone. A microphone key press is processed in
the same manner like a control head key press.
2.4 Status LED’s and Back Light Circuit
All indicator LEDs (red, yellow, and green) are driven by current sources. To change the LED status
the host radio sends a data message to the control head shift register via the SPI bus. The control
head shift register determines the LED status from the received data and switches the LEDs on or
off via Q5-Q7.
The back light for the keypad is always on. The back light current for the keypad is drawn from the
9.3 V source and controlled by two current sources. The LED current is determined by the resistor
at the emitter of the respective current source transistor.
2.5 Microphone Connector Signals
The MIC_PTT line (J802-3) is grounded when the PTT button on the microphone is pressed. When
released, this line is pulled to 9.3V by R805. Two transistor stages (Q802, Q801 and associated
parts) are used to level shift between 9.3V and 3.3V required for the uP while keeping the same
sense (active low for PTT pressed).
Two of the mic socket lines (J802-2,7) have dual functions depending on the type of microphone or
SCI lead connected. An electronic switch (U803) is used to switch these two lines between mic
keypad operation or SCI operation. The switch (mux) is controlled by the uP through J803-20 with
level shifting (and inversion) provided by transistor Q812. When MUX_CTRL (J803-20) is low the
electronic switch is in the mic keypad mode. The mic socket (J802) pin 2 is connected to the keypad
row line that goes to J803-13 and pin 7 is connected to the keypad column line that goes to J803-12.
When MUX_CTRL (J803-20) is high the electronic switch is in the SCI mode. The mic socket (J802
pin 2) is connected to the SCI line that goes to J803-4 and pin 7 is connected to the BOOT_RES line
that goes to J803-11.
The HOOK line (J802-6) is used to inform the uP which type of microphone or SCI lead is connected
to the microphone socket. The voltage of the HOOK line is monitored by the uP (port PE0,
MIC_SENSE) through a resistor divider on the main board. When the HOOK line is grounded (on
hook condition) or floating (2.8V nominal), the uP sets the mux (U803) for keypad operation to allow
the use of microphones with a keypad. When the HOOK line is connected to 9.3V, the uP sets the
mux for SCI operation. This mode is also used to select low cost mic operation where the gain of the
microphone path is increased (on the main board) to compensate for not having a pre-amp in the low
cost mic.
Controlhead Model for CM140 and CM340 2-3
If the BOOT_RES (J802-7) line is connected to >5V (e.g. 9.3V) at turn-on, the uP will start in boot
mode instead of normal operation. This mode is used to programme new firmware into the FLASH
memory (U404 mainboard).
2.6 Speaker
The controlhead contains a speaker for the receiver audio. The receiver audio signal from the
differential audio output of the audio amplifier located on the radio’s controller is fed via connector
J803-1, 2 to the speaker connector P801 pin 1 and pin 2. The speaker is connected to the speaker
connector P801. The controlhead speaker can be disconnected if an external speaker, connected on
the accessory connector, is used.
2.7 Electrostatic Transient Protection
Electrostatic transient protection is provided for the sensitive components in the controlhead by
diodes VR801, VR802, VR803 and VR804. The diodes limit any transient voltages to tolerable
levels. The associated capacitors provide Radio Frequency Interference (RFI) protection.
2-4 THEORY OF OPERATION
3.0 Controlhead Model for CM160 and CM360
The controlhead contains the internal speaker, the on/off/volume knob, the microphone connector,
several buttons to operate the radio, three indicator Light Emitting Diodes (LED) to inform the user
about the radio status, and an 8 character Liquid Crystal Display (LCD) for alpha - numerical
information e.g. channel number or call address name.
3.1 Power Supplies
The power supply to the control head is taken from the host radio’s 9.3V via connector J103-9, The
9.3V is used for the LEDs and back light, the 5V is used for the LCD driver (U3) and level shifter
(U4). The stabilized 3V is used for the other parts.
3.2 SPI Interface
The host radio (master) communicates with the control head through its SPI bus. Three lines are
connected to the shift register (U8):SPI clock (J103-17), SPI MOSI (J103-16), shift register chip
select (J103-15) and LCD driver chip select (J103-18).
When the host radio needs to send date to the shift register, the radio asserts the shift register chip
select and the data is loaded to the shift register. For example, the host radio sends data to change
display channel or change LED status.

3.3 Keypad Keys
The control head keypad is a four-key design. All keys are configured as two analog lines read by
µP. The voltage on the analog lines varies between 0V and 3.3 V depending on which key is
pressed. If no key is pressed, the voltage at both lines is 3.3V. The key configuration can be thought
of as a matrix where the two lines represent one row and one column. Each line is connected to a
resistive divider powered by 3.3V. If a button is pressed, it will connect one specific resistor of each
divider line to ground level and thereby reduce the voltages on the analog lines. The voltages of the
lines are A/D converted inside the µP (ports PE 6 - 7) and specify the pressed button. To determine
which key is pressed, the voltage of both lines must be considered.
The same analog lines also support a keypad microphone. A microphone key press is processed in
the same manner like a control head key press.
3.4 LCD Driver
The LCD (36 x 4 segemnts) is controlled by U3. It has an on onboard clock controlled by R28
(typically 20kHz measured on pin 2). U3 is operated from the 5V supply and is controlled over the
SPI bus (SPI_CLK J103-17, SPI_MOSI J103-16, LCD chip select J103-18). Chip select is active low.
U2 is used to provide level shifting between the 3.3V logic from the uP and the 5V required by U3.
3.5 Status LED’s and Back Light Circuit
All indicator LEDs (red, yellow, and green) are driven by current sources. To change the LED status
the host radio sends a data message to the control head shift register via the SPI bus. The control
head shift register determines the LED status from the received data and switches the LEDs on or
off via Q8-Q10.
Backlighting for the LCD and keys is provided by a matrix of 21 LEDs arranged in 7 columns of 3
rows. The LEDs are driven from a constant current circuit (Q12, U1 and associated parts). There are
4 levels of baclight: off, low, medium and high, which are controlled by two outputs (pins 15, 1) from
the shift register (U8). The current is controlled by transistor Q12. The op amp U1 monitors the
current by measuring the voltage drop across R26, R27 and adjusting the bias of Q12 to achieve the
required level as set by the combined shift register o/ps. When in the off state, Q11 is also turned on
to clamp the base of Q12 so as to force it off. This ensures that the LEDs are fully off. Q11 is
controlled by pin 3 of the shift register U8.
3.6 Microphone Connector Signals
The MIC_PTT line (J102-3) is grounded when the PTT button on the microphone is pressed. When
released, this line is pulled to 9.3V by R33. Two transistor stages (Q14, Q13 and associated parts)
are used to level shift between 9.3V and 3.3V required for the uP while keeping the same sense
(active low for PTT pressed).
Two of the mic socket lines (J102-2, 7) have dual functions depending on which type of microphone
or SCI lead that is connected. An electronic switch (U41) is used to switch these two lines between
mic keypad operation or SCI operation. The switch (mux) is controlled by the uP through J103-20
with level shifting (and inversion) provided by transistor Q41. When MUX_CTRL (103-20) is low the
electronic switch is in the mic keypad mode. The mic socket (J102) pin 2 is connected to the keypad
row line that goes to J103-13 and pin 7 is connected to the keypad column line that goes to 103-12.
When MUX_CTRL (103-20) is high the electronic switch is in the SCI mode. The mic socket (J102
pin 2) is connected to the SCI line that goes to J103-4 and pin 7 is connected to the BOOT_RES line
that goes to J103-11.
2-6 THEORY OF OPERATION
The HOOK line (J102-6) is used to inform the uP which type of microphone or SCI lead is connected
to the microphone socket. The voltage of the HOOK line is monitored by the uP (port PE0,
MIC_SENSE) through a resistor divider on the main board. When the HOOK line is grounded (on
hook condition) or floating (2.8V nominal), the uP sets the mux (U8) for keypad operation to allow the
use of microphones with a keypad. When the HOOK line is connected to 9.3V, the uP sets the mux
for SCI operation. This mode is also used to select low cost mic operation where the gain of the
microphone path is increased (on the main board) to compensate for not having a pre-amp in the low
cost mic.
If the BOOT_RES (J102-7) line is connected to >5V (e.g. 9.3V) at turn-on then the uP will start in
boot mode instead of normal operation. This mode is used to programme new firmware into the
FLASH memory (U404 mainboard).
3.7 Speaker
The controlhead contains a speaker for the receiver audio. The receiver audio signal from the
differential audio output of the audio amplifier located on the radio’s controller is fed via connector
J103-1, 2 to the speaker connector P101 pin 1 and pin 2. The speaker is connected to the speaker
connector P101. The controlhead speaker can be disconnected if an external speaker, connected on
the accessory connector, is used.
3.8 Electrostatic Transient Protection
Electrostatic transient protection is provided for the sensitive components in the controlhead by
diodes VR1 - VR4. The diodes limit any transient voltages to tolerable levels. The associated
capacitors provide Radio Frequency Interference (RFI) protection.
