Major 3 TRC
General Operating Instructions
The Major 3 is controlled by a micro processor. It is used to control radio systems. To program
the Major 3 you use easily the keyboard.
There are two main versions of Major 3. One for use with 12 V DC main power and one with
integrated 230 V AC power supply.
On the rear side is 25-pin connector. This is for connecting squelch input, ptt output, audio in/output,
5 plus 1 digital outputs. You can also connect the DC power to this.
The Major 3 with option FFSK/RS232 has an RS232 Interface. You can use it to program the Major
3 or connect a terminal for special purposes.
Only the Major 3 for 230 V AC has an power switch on the rear side. After switching on the display
shows for one sec. <Futro>. Then the cursor ashes for input.
Before rst use of Major 3, you have to adjust audio levels to the radio.
Busy Indicator and carrier input
The busy indicator and as well the carrier input is programmed with EEPROM register 053 on 1.
position. Any voltage from 0 to 2 volt is detected as low and a voltage from 3 to 12 volt as high. If you
have an 2-wire connection you can use the carrier input to transmit a programmed tone sequence. In
case of a two-wire system the busy indicator is controlled by voice activity.
Register 053
1. position busy indicator on when
0 = carrier input < 2V
1 = carrier input > 3V
2 = audio squelch, 2-wire connection
3 = audio squelch, 2-wire connection, transmitting tone sequence when
carrier input is true
Loudspeaker indicator
Is switched on if the loudspeaker is open. The indicator ashes if an incoming call is detected. In
this case the loudspeaker is also switched active.
Loudspeaker
To change the volume push the button loudspeaker key. The display shows <VOL> and now you
can enter a new value from 0 to 9.
You can switch on and off the loudspeaker by pushing the loudspeaker key. The loudspeaker is also
active after pushing the PTT, after transmitting a call or if a incoming call is detected.
The loudspeaker is switch of manually by the loudspeaker key or automatically with a programmable
timer.

Call Handling
You can talk to the radio subscriber by pushing the PTT. After releasing the PTT button you will
hear the radio subscriber through the loudspeaker. Normally, after call termination, the loudspeaker
is switched off by the loudspeaker key.
Calling Radio Subscriber
At rst, the call number is entered via the key pad. The input is complete when the number
is right-aligned on the display. None of the input positions is ashing any longer. The call is
transmitted by pressing the call button.
Short Call Numbers
The Major 3 is provided with 10 programmable short call numbers. By pressing the (Z) key and
the following input of a digit between 0 and 9, a precoded call is transmitted. These short call
numbers are coded in registers 000 to 009.
Group Call
In order to be able to use the 5-tone sequence call system without any restrictions, tone 'A' should
be used as group calling tone. Tone 'A' is entered by the (*) key. The group calling tone may be
placed at any position. The call starts by pressing the call button.
Transmitting a tone sequence with analog input
By switching the analog input to ground the 5-tone sequence in register 011 is transmitted. This
function is activated in register 054.
Register 3. position analog input
0 = no function
1 = transmitting 5-tone
Transmitting a tone sequence with carrier input
By switching the carrier input to ground the 5-tone sequence in register 012 is transmitted. This
function is activated in register 053. See section Busy Indicator and carrier input.
Call from Radio Subscriber
An incoming call is registered by a bell tone. The loudspeaker is switched on and the loudspeaker
LED ashes.

Input the status code
If you hold down the (Z) key for a moment you enter the status mode. Now you can enter a
one or two digit status.
Transmitting a call by pushing the PTT
You can transmit a 5-tone or FFSK code by pushing the PTT. The code from register 015 is used.
Register 053
3. position 0 = no transmission
1 = FFSK code transmitted
2 = 5-tone code transmitted
Transmitting a call by releasing the PTT
You can transmit a 5-tone or single tone (roger peep) code by releasing the PTT. The 5-tone
code from register 015 is used.
Register 053
4. position 0 = no transmission
1 = roger peep 2800 Hz
2 = 5-tone code + status transmitted
2 = 5-tone code + status + roger peep transmitted
5-Tone Sequence Encoder
Precoding
The 5-tone sequence encoder is congured according to the application requirements and as well
for comfortable operation. Logically, you will permanently code those positions which should not be
entered via the key pad. The permanently coded tones can be placed at any position of the tone
sequence. Use F for variable positions. For example, it is possible to permanently code positions 1,
3, and 5. In this case only position 2 and 4 are entered via the key pad. The positions to be freely
entered are always displayed right aligned. If two subsequent tones are identical, the repeat tone
is automatically used at the correct position. The 5-tone sequence encoder is coded in register 010.
See section EEPROM 1 Programming Mode.
Call with ID code
The ID code is programmed in register 015. Normally the ID code is programmed same as decoder
1. The sequence of ID code and call code is programmed in register 053.
Register 053 2. position 0 = no code
1 = call code + ID code (double sequence)
2 = ID code + call code (double sequence)
3 = call code + ID code (6-tone sequence)
4 = call code + ID code (7-Tone sequence)
5 = call code + ID code (8-Tone sequence)
Transmitting call with status
The status can be one or two digit. It is added on the end of the tone sequence.
Register 054 1. position 0 = no status
1 = status one digit
2 = status two digit

Receiving of calls
The Major 3 has 10 decoders. They are coded in registers 020 to 029. If you don't need a decoder,
put in an F on rst position. You can also program different modes in the registers 030 to 039.
The following modes are possible.
- managing of double sequences
- managing of tone sequences with more than 5 tones
- display of received ID codes
- bell tone
- on time of emergency contact
- acknowledgement
- loudspeaker mode
Decoder 1
The Decoder 1 is coded in register 020. Every tone sequence is compared with the decoder 1 coding
and in case of positions being coded with 'F', every tone of the tone system will be accepted. If the
tone sequence has been identied as correct, the loudspeaker is switched on, the loudspeaker lamp
ashes, and if you are not operating with double sequences, the acknowledgement is transmitted.
After that, the bell tone is activated. If you operate with double sequences, the acknowledgement
delay is at most one second. Any further tone sequence check, for example by decoder 2 or the
conference call decoder, is not performed.
Bell Tone
The bell tone volume is according to the basic programmed volume. You have the choice of
10 different bell tones (1 to A). If no bell tone is desired, a '0' has to be programmed at
this position.
Alarm Switching Output
After successful evaluation the bell tone is generated and the alarm contact is switched for n*1
seconds. The alarm time is programmable for each decoder. The alarm contact time is programmed
in one-second intervals in registers 030 to 039 3. position.
Acknowledgement
The automatic acknowledgement after a selective call can operate in different ways. The
acknowledgement mode is programmed at position 4 of register 030 as follows:
0 = no acknowledgement
1 = standard acknowledgement (from register 017)
2 = acknowledgement with a single tone of 600 Hz for 300 msec
3 = acknowledgement with a tone sequence from register 015 (ID-code)
4 = acknowledgement with the identication last received
5 = additionally standard acknowledgement (from register 017), used for FFSK
Group Call Decoder
The group call decoder for tone A or 0 can be programmed for each of the ten decoders. Program
tone A or 0 on the position you want. Don't forget to block acknowledgement.

Conference Call Decoder
The conference call decoder detects a tone of at least one second duration. After detection the
loudspeaker is switched on, the loudspeaker lamp ashes, and the bell tone is activated. No
acknowledgement is transmitted. The conference call tone frequency is coded at position 1 of
register 044 with the corresponding digit of the tone system ('0' ... 'E') . If this decoder is not
required, please code an 'F' at that position.

.
A = bell tone type 9
3. position n * sec. emergency output on
4. position n/a
5. position loudspeaker
0 = always off
1 = on if call detected
Emergency Decoder
The emergency call decoder is coded in register 046. If this decoder is not required, please code
an 'F' at the rst position of the tone sequence. The read in 5-tone sequence is compared with the
emergency coding. From the second up to the fth position those positions being coded with 'F' will
accept all tones of the tone system. The 5 tones has to be followed by a 6th tone. This tone is coded
in register 046 on 5. position. In case of successful decoding the loudspeaker is switched on. The
emergency output is activated. As long as an emergency call is indicated on the display, the key
pad is blocked with exception of the PTT button.
ID-Code Memory
The ID-code memory can be congured so that it is optimal adapted to current use. Up to 16
ID-codes can be stored. If all memory positions are engaged, the memory is updated by deleting the
oldest ID-code. The stored ID-codes can be scrolled through by pressing the (#) key in such
way that the ID-code stored last is displayed by the rst key pressing. The currently displayed
ID-code can be deleted from the memory by pressing the (#) key longer. If the "FIFO" function is
switched on, always the oldest number is shown on the display by pressing the (#) key and only
after deleting this ID-code the next ID-code follows. The "FIFO" function is programmed at the
second position of register 043. The ID-code memory can be used for single or double sequences
as well as for 6, 7 and 8 tone sequences.
Key Tones
The key tones are coded in register 016. The coding of these tones selects the ID-codes which are
stored, and determines the digits to be displayed. Those positions where every tone is allowed and
which are displayed later on, has to be coded with 'F'.

Memory updating
Before an ID-code is accepted by the ID-code memory, the software checks if the same ID-code
has already been stored in the memory. If the ID-code has already been stored and if the updating
has not been activated, the ID-code is rejected. If the updating is switched on, the ID-code at
the old position is deleted in order to be stored again at the rst position. Therefore, the ID-code
memory is always arranged in chronological order. The memory updating is programmed at
position 1 of register 021.
Tone length encoder
The length of the rst tone is dened at positions 1 and 2 of register 042. The length of the other
tones can be adjusted at position 3 of register 042. The value can be switched in 10 msec intervals.
The tone length of the rst tone can also deviate from the other tones.
Tone length decoder
In case of tone identication a tolerance has to be added. This ensures that even inexact 5-tone
telegrams are evaluated correctly. The minimum tone length is programmed in register 040 at
position 4 and 5. The maximum tone length of the rst tone is programmed in register 040 at position
1 to 3. The maximum tone length of the others is programmed in register 041 at position 1 to 3.
The values are adjustable in 5 msec steps.
Tone length of the emergency tone (decoder)
The emergency tone is the 6th tone. The minimum length is dened in register 045 at position 4
and 5. The maximum is programmed in register 045 an position 1 to 3. The values are adjustable
in 5 msec steps.
Tone Systems
The Major 3 can be congured for various tone systems without any hardware modication. The
tone system is selected at position 5 of register 046. When a tone system is selected, the tone
length is not automatically adjusted. Therefore, if a change is made from ZVEI 1 to CCIR, the
tone length has to be redened as well.

Transmitter keying
The transmitter can be keyed by the red PTT button on the key pad. The transmitter is keyed as long
as the PTT button is pressed, except if the TX time out is exceeded. In the multi wire version it is
controlled by an open collector output and in AC version by a pilot tone.
TX time out timer
The TX time out timer is programmed in one second intervals at positions 1 to 3 of register
051. Values of '000' up to '255' are permitted. If the programmed value is '000', the TX time
out timer is out of operation.
Transmitter prerunning time
The prerunning time is preceding every call before connecting the audio. It can be programmed
in 10 msec intervals at positions 1 to 2 of register 052. The variable value can be dened freely
between '00' and '99'.
PTT button blocking
The PTT button blocking is programmed at position 5 of register 052.

FFSK mode (option)
The Major 3 can be used in combined networks if it is provided with FFSK option. In this case an
FFSK modem operates simultaneously with the 5-tone modem. The Major 3 operates according
to ZVEI recommendation.
Telegram Structure
The call telegram starts with an unmodulated carrier which has to be available at the receiver side
for at least 25 msec. It is followed by telegram reload with a 16 bit 1/0 sequence and the block
synchronization. For block synchronization a 15 bit "barker word" with a preceding '1' is used. The
now following selective call number is built as decade. It always consists of 8 digits. The telegram is
saved by an additional 8 bit redundancy.

Kompetent für Elektroniksysteme
FFSK Encoder
While the 5-tone and the FFSK decoder are ready for detection simultaneously, it has to be
decided for call transmission whether a 5-tone or FFSK telegram shall be transmitted. The
Major 3 derives this selection from the call number and automatically transmits the call in the
correct call mode.
The 8-digit selective call number is arranged as follows:
1. position xed operating mode reference (BAK)
2. position xed status
3. position xed rhomb
4 ... 5. position variable manufacturer reference
6 ... 8. position variable Call code
The encoder is congured according to the application requirements and as well for comfortable
operation. Logically, you will permanently code those positions which should not be entered via
the key pad. The permanently coded tones can be placed at any position of the manufacturer
reference and call code. For example, it is possible to permanently code positions 4, 6, and 8. In
this case only positions 5 and 7 are entered via the key pad. Usually, the rst two or three digits
are permanently coded. The positions to be freely entered are always displayed right aligned. The
FFSK encoder is programmed in register 010.
Operating Mode Reference
The operating mode reference ("Betriebsartenkennzeichen" = BAK) is the criterion for different
telegram forms:
0 At disposal
1 Q Call to mobile
2 Q Call to master station
3 Identication
4 Acknowledgement
5 Following telegram
6 Q Break call
7 Reserved
8 Q Priority call
9 Q Status report
A Reserved
B Reserved
C Reserved
D At disposal
E At disposal
F Emergency call
BAKs marked with Q require an acknowledgement. In case of coding a '0', '2', '3' or 'F' every
telegram is processed by the FFSK decoder.
Limit Number
The limit number is programmed at positions 1 to 3 of register 060. Call codes lower than the limit
number are transmitted as 5-tone sequence; call codes higher or the same as the limit number
are transmitted as FFSK telegram.

Rhomb
The rhomb is programmed at position 5 of register 060. Application at disposal.
FFSK Emergency Call
If a FFSK telegram with status = emergency call is received, the loudspeaker is switched on, the
loudspeaker lamp ashes, the emergency call ID-code is stored and ashes on the display. As
long as an emergency call is displayed, the key pad is blocked (exception PTT). An emergency
call can be deleted by pressing the (#) key.
FFSK Decoder
The decoder 1 to 10 are coded in registers 020 to 029. The telegram detected is compared with
the decoder 1 coding and in case of positions being coded with 'F', any digit is accepted. If the
FFSK telegram has been identied as correct, the loudspeaker is switched on, the loudspeaker
lamp ashes, the FFSK acknowledgement is transmitted and the bell tone is started. No further
telegram check will be performed.
The decoder 2 is coded in register 007 (EEPROM 1). See section EEPROM 1 Programming Mode.
The telegram detected is compared with the decoder 2 coding and in case of positions being coded
with 'F', any digit is accepted. If the FFSK telegram has been identied as correct, the loudspeaker
and the handset are switched on, the loudspeaker lamp ashes and the bell tone is started. No further
telegram check will be performed. An acknowledgement is not transmitted.
FFSK Acknowledgement
After detection by decoder 1 the FFSK acknowledgement is transmitted. The acknowledgement
is coded in register 017. If no acknowledgement is required, position 4 of register 030 ... 039
is coded with '0'.
Register 030 ... 039 4. position 0 = no acknowledgement
1 = FFSK standard acknowledgement
2 = single tone 600 Hz for 300 msec
3 = ID code
4 = received ID code
5 = FFSK standard acknowledgement + 5-tone acknowl.

EEPROM Programming Mode
After selecting the EEPROM programming mode, the left display shows the message <Pas>, and the
cursor ashes at the input position of the right display. Now you have to enter your 5 digit password.
Units leave the factory without password, so that you can immediately start with the programming.
In this case or after you have entered your password, the left display shows the message <Adr>,
and the cursor ashes at the input position of the right display.
Now the register address to be newly coded has to be entered. If, instead of a valid address, '222'
is entered, all registers are programmed with default values. Immediately after complete input the
left display shows the message <co> and the actual coding is shown on the right display. Now that
coding can be over written with new values. Generally, in setup mode you conrm the last input by
pressing the (#) key. Pushing (#) key again escapes the setup program.
All values from 0 ... 9 and A ... F
can be used for coding.

Service mode analog switches
During service work it can be necessary to switch a certain signal path. Since the processor controls
all analog switches they can be switched by the service program.
After selecting the service mode analog switches put in the number of the switch to control. Now the
input is ashing and waiting for a 0 or a 1 (0=off, 1=on).
With the # key you can enter the next switch. If you enter # key again, the service mode is
escaped.
Service mode potentiometer
During service work it can be necessary to adjust a certain signal path. Since the processor controls
all potentiometers they can be adjusted by the service program.
If you use a password, you have to enter when the display shows <Pas>.
Enter the potentiometer number to adjust. Now put in a 0 to adjust anticlockwise or a 1 for clockwise.
Steps from 0 to F are possible.
For adjusting TX output level (CS3) a 1000 Hz tone is transmitted automatically.
Potentiometer Function Poti number
CS1 loudspeaker volume 1
CS2 RX input level 2
CS3 TX output level 3
Transmit leveling tones
For leveling the Major 3 it is possible to transmit different tones. Enter setup mode number 4. The
display shows now <ton>. Push a key according to the table below.
To change the frequency push an other key. To escape the mode push # key.
Adjustment
1) Adjusting audio input
- Connect a signal of 1000 Hz at nominal level to the input
- Disconnect the loudspeaker, connect a 8 Ohm resistor instead and level meter
- Adjust the volume to max. level (9)
- Switch on the loudspeaker by pushing key
- Adjust the level with poti no. 2 (CS2), nominal level is + 10 dBm
0 = 200 Hz 5 = 1000 Hz *
= 2900 Hz
1 = 300 Hz 6 = 1600 Hz = 3000 Hz
2 = 400 Hz 7 = 2400 Hz = 3100 Hz
3 = 600 Hz 8 = 3400 Hz Z = 3300 Hz
4 = 800 Hz 9 = 4000 Hz = 1200 Hz
