The Major 6a is the newer design of the well-known Major 6. The display is an alphanumeric LC dis­play with background lighting. A gooseneck microphone with high dynamics is standard. All keys can
be programmed freely. Two different functions can be assigned to each key.

Up to 4 radios can be connected and used simultaneously by using a multi-core cable (7 cores) for each
radio. There is a squelch input, a PTT output, a potential-free AF input and a potential-free AF output
for each radio.
A headset and a voice recorder (all 4 radio channels merged on one output) can also be connected.
Futhermore there are 3 switching outputs (alarm switching output, recorder control and headset
switching) and a serial interface (RS232 or optional RS485) .

For the exact pinout see section Sockets pin layout connections.

The Major 6a can be programmed by using the keyboard. For displaying a protocol a printer or a ter­minal can be connected to the serial port.The serial port can also be used for service or special appli­cations.

The Major 6a is automatically turned on if connected to power supply. After turning it on <Funk Tronic
Major 6a> is displayed for a second , then the device is ready for operation.

Hint :

At initial operation the Major has to be leveled to the radio system !

LC-Display

All alphanumeric displays are shown on a LC-display with background lighting
(2 lines with 24 characters) .
The display lighting can be configured in the EEPROM-register 009. For programming the
EEPROMs please read the section Programming mode EEPROM-addresses. The display
lighting is turned on ex factory.

Busy LED

The busy LEDs (channels 1..4) are programmed in the EEPROM-register 095 at the digits

1.-4. To control the busy LED any DC voltage between 0V and 1,25V or between 3,75V and 12V

can be used. The operating mode can be configured as follows:

Register 095 1. - 4. digits busy LED

2 = with squelch input < 1,25V (LOW)

4 = with squelch input > 3,75V (HIGH)

TX LED

For each of the four channels there also is a separate TX LED , which lights up when the
corresponding transmitter is activated. The transmitter is activated by pushing a PTT button while
talking or transmitting a call.
Flashing of the TX LED means that another Major 6a is already using this channel (PTTT output
on LOW < 3V).

Loudspeaker LED / Call detection LED

The loudspeaker LED (channel 1..4) lights up when the loudspeaker of the corresponding
channel is activated on operating volume.
A flashing loudspeaker LED means that a call has been detected (call detection LED). The call
detection LED disappears when the corresponding channel is actively used for transmitting, or
when the channel is activated (register 001/2).

F-Buttons (channel buttons) LED

The function of the F-buttons LEDs is programmed in register 001 at the 1st digit.
The LEDs (LEDs in the selection buttons) flash when there is at least one identified call saved in

the identification memory of the corresponding channel. The corresponding LED disappears only
after all identifications have been deleted in the corresponding identification memory.
Also see section Identification Memory - (register 001/1 = 2).

The LED is turned on if the corresponding channel is activated - (register 001/1 = 1)

The LEDs are always turned off - (register 001/1 = 0)

Ex factory programming of the buttons

This specification is valid for the ex factory programming of the buttons.

As all buttons can be programmed freely the functions of the buttons of individually programmed
Major 6a can differ from this description.

Channel selection

To activate one of the four channels push the corresponding selection button F1 to F4. To
deactivate a channel again push the same or a different selection button. You can also select
several channels simultaneously by keeping the first selected channel button(s) pushed down
while additionally selecting more channels. When channels are activated the corresponding
loudspeaker LED lights up.

Example:

Communicating with the calling radio subscriber

There are three different ways of communicating with a calling radio subscriber:

a) By pushing the red PTT button the transmitter of the selected channel is turned on (the
corresponding sending status LED

lights up) and you can talk to the caller through the
gooseneck microphone.
After depressing the PTT button the caller can be heard on the loudspeaker in regular operating
voulme. The volume of the loudspeaker is adjustable. See section Switching of the loudspeaker

status and Regular operating volume.

b) Or by picking up the handset and pressing the PTT button on the inside of the handset. By doing

this the trasmitter of the selected channel is activated (TX LED lights up) and you can talk with the
caller through the microphone of the handset. You can hear the caller on the handset. The call is
ended by replacing the handset.
The volume of the earphone and the microphone level are each adjustable with a potentiometer.
The potentiometer is situated near the earpiece of the handset and is easily accessible from the
outside by using a screw-driver through a small opening on the inside of the handset.

c) Or by connecting a compatible headset and pressing the corresponding PTT button (e.g. a
foot switch), which has to be connected to the PTT input (connector

ST12/ST13). By doing this
the transmitter of the selected radio channel is also turned on (TX LED lights up) and you can talk
with the caller through the microphone of the headset. You hear the caller on the earphone of the
headset.
The volume can be adjusted with the button S4 (long).

The microphone sensitivity can be adjusted separately for all 3 microphones in the setup menu
„level adjustment“.

!!) If a PTT button is pushed without having selected a channel, there are two possible reactions
of the Major 6a, depending on the programming of the 3rd digit in the EEPROM-register 001
(0 = latest selected channel; 1 = signal tone) :

a) the latest selected channel is activated automatically. After turning on the radio installation no
channel is activated, so that in this case channel 1 is activated automatically, or

b) a signal tone on the loudspeaker draws the user´s attention to the operating error.

After ending the call the activated radio channels can be deactivated by pressing the corresponding
selection buttons again or by pushing button S4.

Switching of the loudspeaker status

By selecting a radio channel the loudspeaker is switched to the activated channel in regular
operating volume. See section Regular operating volume. If no channel is activated the
loudspeaker can be switched to the latest activated channel(s) in regular operating volume by
pressing button S4.

After that the loudspeaker can switched back to listening volume by pressing the corresponding
selection buttons or button S4. See section Listening-in-volume .

After detecting a call the loudspeaker is automatically switched to the corresponding channel for
an adjustable period of time in the calling volume - unless the channel has already been activated.
See section Calling volume.

The loudspeaker can be muted by shortly pressing the loudspeaker button.
If the receiver is lifted the loudspeaker is automatically muted. By putting down the receiver the
loudspeaker is automatically turned on again.

The possibilty of interconnecting the regular operating or the listening volume to the earphones,
the loudspeaker (and/or the recorder output ) is configurated in the EEPROM-register 000.

Register 000 Configuration for AF interconnections
1st digit RX-AF on receiver / headset

2nd digit RX-AF on recorder output
3rd.digit on loudspeaker, when receiver is put down
4th digit on loudspeaker, when receiver is lifted
5th digit allows RX-AF on loudspeaker during PTT

valid for all digits:

0 = no AF
1 = AF of activated channels
2 = listening in-AF of deactivated channels

3 = AF of acitvated channels and listening in-AF

Regular operating volume

To change the regular operating volume  rst press down the loudspeaker button for a longer time.
The display now shows <Total volume> and next to this on the right side the prompt  ashes. The
volume can be set between '0' and '9' . The set volume is saved even after turning off.
But a set power-on-volume can be programmed in register 090/1+2.

Listen-in-volume

If a radio channel is not activated,you can „listen in“ on it with the listen-in-volume. To change
the listen-in-volume (channel x) keep the corresponding selection button F1 to F4 pressed for a
moment. The display now shows <listen-in channel

x : > and the prompt  ashes. The volume
can be selected between '0' (listen-in=OFF) and '9' (listen-in-volume=operating volume) . The set
volume is saved even after turning off.
But a set listen-in-volume can be programmed in register 091/1-5.

Call volume

If a channel is not activated the loudspeaker is switched to this channel in call volume for an
adjustable length of time after detection of a call. Then the loudspeaker returns to its previous
status .
The length of time can be encoded for each of the ten decoders in steps of seconds (0..F = 0..15)
in the EEPROM-registers x30 - x39 at the 4th digit.
The call volume of the 10 decoders (channel 1..4) can be programmed between '

0' (call volume

= OFF) and '

9' (call volume = operating volume) in the above mentioned EEPROM-registers at

the 5th digit.

An adjustable volume can be selected with A - F. „A“ meaning the latest set volume , B (+1) to F
(+5) a volume increased by 1 - 5 levels.

It is possible to record calls with the built in recorder/monitoring interface. The interface has a

potential-free AF-output

and a switching contact to ground for controlling the recorder.
The switching contact switches according to the conditions programmed in register 002 at the
4th and 5th digit if:
a) a squelch can be detected on a channel or
b) at least one channel is activated (channel selection LED

lights up) and a squelch can be
detected on this channel (busy status LED lights up) and/or
c) the channel is used for transmitting (TX LED lights up).
After discontinuation of these criteria the contact is turned off with an adjustable delay time

.

This delay time is programmed in steps of seconds in the EEPROM-register 002 at the 1st - 3rd

digit.

Recording of a call

Kompetent für Elektroniksysteme

Several Major 6a´s can be interconnected without any problems as the AF-outputs are only activated
during transmitting and the AF-inputs can be switched to high-impedance by disconnecting jumpers
JMP1 / 1 - 4 (see section Layout) .
For this purpose all connections with the individual radio channels (TX-AF, RX-AF, squelch and
transmitter PTT) only have to be connected in parallel circuit (bus- or hub wiring).

The audio-frequency-connection is not integrated in the Major 6a anymore. But by connecting
the external headset-adapter the headset can be used as a combined communicating device for
telephone and radio. The headset is switched to the telephone by an opto-coupler input, which
has to be programmed accordingly (see section Opto-coupler input).

To transmit a call at least one channel has to be activated. If no channel has been selected manually
a signal tone on the loudspeaker draws the user´s attention to the operating error.

Calling by selective call

First at least on channel has to be selected with a selective call. Then the calling code is entered
by using the numerical keys

1 ... 9

. The entry is complete when no prompt flashes anymore. The

call is transmitted with the call button and can be repeated with it.

Calling by short dial

The Major 6a has 10 codeable short dials per channel. The corresponding short dial for an
activated channel is transmitted by shortly pressing the button Z and then entering a number
from '0'...’9' .
The short dials (channel 1..4) are programmed in the EEPROM-registers x00 - x09.

Calling by group call

To be able to use the calling system without any restrictions, the special tone 'A' should be used
as a group call signal. This special tone 'A' is entered with the button * . The group call tone
can be entered at any position. By pressing the call button the call is started and can also be
repeated by using this button.

Calling by collective call /single tone call

It is possible to preselect 9 collective call frequencies (0..8) per channel . The frequency codes of
these single tones are calculated according to this formula

1.008.000
X = -----------------­ F [Hz]

and are coded in the UGA(1..4)-registers 000...008 as four digit hex-numbers. Please read the
sections Programming mode UGA and Attachment, Conversion table (...).

Example: collective call 1 (channel 2) has the frequency 2135 Hz, then this results in:

1.008.000
X = ------------------ = 472,13 ==> hex-value = $01D8
2135
therefore UGA(2)-reg. 001 = 01D8.

The corresponding collective call signal (single tone) of the activated channel is transmitted by
pressing a collective call button which has been programmed accordingly.
The number and the duration of the collective call signal 0...8 which is to be transmitted is dened
when programming the button.

Ex factory there is no button programmed for collective call .

Status input

By pressing a status input button programmed for this purpose you get to the status input of
the activated channels. Also see section Transmit call with status. Now you can enter a status
with up to three digits by using the numerical keys 0...9 or you can use the button * to delete a
previously entered status. The input is complete when no prompt ashes anymore. After that the
display returns to the standard display.

Ex factory there is no button programmed for status input.

Return call

If you keep the call button pressed down for a moment the ID (received call) which is currently
shown on the display is transmitted as a call.
Also see section Identication memory.

The return call channel can be adjusted in register 001/5.

Signaling when pressing or depressing the PTT button

The signaling has to be dened in the function of the buttons or the inputs (reg. 010-089).
No signalings have been activated ex factory.
Every time when starting and/or ending using a PTT button the own ID (from/in EEPROM­register x15) and/or a „Roger-Peep“-tone (from/in EEPROM-register x53) can be transmitted
automatically.

An individual „Roger-Peep“-tone can be preselected for each channel. The frequency code of this
single tone is calculated according to the following formula

1.008.000
X = -----------------­ F [Hz]

and is coded as a 4-digit hex-number in one of the UGA(1..4) - registers 000-008. Please also
read the sections Programming-mode UGA and Attachment, Conversion table (...).

Example: Roger-Peep tone 0 (channel 3) shall have the frequency 2000 Hz, therefore:

1.008.000
X = ------------------ = 504,00 ==> hex-value = $01F8
2000
therefore UGA(3)-reg. 000 = 01F8.

The duration and the relating single-tone register in the UGA is programmed in register x53.

Preadjustment of  xed tones

It makes sense to program the digits of the tone sequence, which shall not be entered with the
keyboard. These tones can be set at any position of the tone sequence. Therefore it is possible
to  x the 1st, 3rd and 5th position. In this case the 2nd and 4th position is entered by using the
keyboard. If there is a sequence of identical tones the repeat tone is automatically inserted at the
correct position. The encoders (channel 1..4) are coded in the EEPROM-registers x10. Also see
section Programming mode EEPROM.
The pre xed tones can always be displayed with the call input, so that different quantities of variable
digitis can be coded for the encoders. If there are several channels activated at the same time
the pre xed tones of the lowest-order channel are used automatically.
The quantity of the displayed tones is programmed in the registers x55 at the 4th digit.
To turn off the tone sequence encoder use the programming EEEEE.

Transmitting a call with ID

IDs (channel 1..4) are coded in the EEPROM-registers x15 . (Normally the ID has the same
code as the encoder 1, but if necessary a different code can be chosen.)
Depending on the con guration the ID is automatically transmitted before or after each call or short
dial, and either a connecting tone or a rest with adjustable duration is inserted between the two
tone sequences of a double sequence. The duration is coded in steps of 5ms in the corresponding
UGA(1..4)-register 243 at the 1st+2nd digit (hex-value !) . The connecting tone resp. the rest
(0..E = tone 0..E; F = rest) is coded at the 5th digit for the button and enter functions - function
2 (transmit call).
If the ID mode is used with 6-, 7- or 8-tone sequences, the last 1 -3 digits of the ID are attached
to the call number.

Transmitting a call with status

The status selection is con gurated in the EEPROM-register 005 at the 1st digit . If no status
selection is necessary please code this position with '

0'. The status can be con gurated with up
to three digits and is attached to the end of each 5-, 6-, 7- or 8-tone sequence (not for double
sequences !), and the length is increased by up to three digits. If the ID mode is used with 6-, 7-
or 8-tone sequences, an 8-tone sequence for example is turned into a 10-tone sequence when
there is a 2-digit status selection.

For information on status input see section Transmitting calls.

Con guration of the tone sequence encoder

m6a-eng (18.12.2009)

- 15 -

Kompetent für Elektroniksysteme

The Major 6a can identify up to 10 different decoder programmings per channel. The IDs of the
10 decoders (channel 1..4) are coded in the EEPROM-regi sters x20-x29 . Decoders which are
not needed have to be coded at the 1st + 2nd digit with 'E' or at the 8th digit with '0'.
The con guration can be adjusted separately for each decoder of the 4 channels in the EEPROM-
registers x30-x49. The following features can be con gured:

- call tone

- call volume

- ID-mode

- alarm switching output and its activation time

- acknowledgement mode

For simplicity the following information always refers to decoder1 of channel1, the con guration
of which is programmed in the EEPROM-registers 130+140 . All other decoders (if needed) are
programmed in the same manner.

Decoder (1)

The decoder1 of channel1 is coded in the EEPROM-register 120 at the digits 1-7. Please also
read section Programming mode EEPROM. Variable tones and tones which are not used, have
to be programmed with 'F'.
Each received tone sequence is compared with the programming of the decoder, and every tone
of the tone sequence at the positions coded with an 'F' is accepted.
The decoder can be activated or deactivated at the 8th digit in register 120.
After the correct identi cation of the tone telegram the ID (if available) is saved (if con gured), the
con gured acknowledgement is transmitted, the loudspeaker is activated with the call volume (if
the channel has not already been activated) and the con gured call tone is started.

If double sequences are used the acknowledgement is delayed by 1 second max. . Also see

Identi cation memory.

There is no additional check of the tone sequence by decoders with higher indices. Principally
decoder1 has the highest priority and decoder 10 the lowest when decoding a telegram.

Call tone

The sound of the call tone can be con gured separately for each decoder of each channel in the

EEPROM-registers x30-x39 at the 1st digit.
You can choose between 10 different types of call tones '

1'...'9' and 'A' . The types 1-5 can be

repeated up to 9 times. For this the 1st digit has to be programmed with '

B' (type 1) ... 'F' (type

5). If you don´t want a call tone program '0' at this digit.
The duration of the call tone can be programmed in the above mentioned EEPROM-registers at
the 2nd digit in steps of 200ms (0,2...3 sec / 0=in nite) and the volume of the call tone can be
programmed at the 3rd digit(0..9, A...F).

0 - 9 = set volume
A = actual volume
B - F = actual volume + 1(B) - 5(F) steps

Receiving calls
