Major BOS 2b2
Connectivity
This desktop radio contoller can be connected to up to four two way radios. Every base station can be
supplied with squelch input, PTT output, a busy line and AF ins and outs. In addition the Major BOS
2b2 provides a headset connector, an external signal encoder imput and a tape recorder output. It is
possible to connect the unit to a PC via RS232 interface for programming purposes.
It is possible to operate multiple Major BOS2b2 in parallel circuit because AF outputs are internally
disconnected in idle or receiving mode.
Keys
The keboard presents four selection keys for the max. of four radio devices, two tone call keys and
the red PTT key.
Carrier Indication (Squelch)
Every one of the four radio circuits provides its own carrier indicator (Squelch), which is located above
the corresponding selection key. For activation the squelch input needs a voltage between 5V and
14V. The logic of the carrier indication is configurable. The polarirty of the carrier indication and the
AF muting when no carrier is present can be programmed.
Transmitter Indication (PTT)
Every radio circuit has its own transmitter indication. This is lit on transmitter activation. This happens
on pushing a PTT button or one of the both Tone Call buttons. The LED blinks if a parallel Major BOS
2b2 is on transmission.
Selection Indication
The selection indicator is permanentely luminous if the corresponding radio circiut is selected and
active. If it is in blinking state this circuit is busy and cannot be selected.
Selection of Base Stations / Radio Circuits
To connect to one of the four radio circuits the corresponding selection key is to be pressed. A
subsequent button press sets the circuit to inactive. To activate more than one channel hold the first
pressed button down and select further circuits. Programming the Major BOS2b2 can disable this
feature. Acitve circuits are indicated by a luminous selection indication LED. A busy radio cuircuit is
idicated by a blinking LED. Radio circuits can be disabled, active radio circuits on power on can be
programmed.
Loudspeaker and Volume Control
On transmission the loudspeaker is turned off automatically. If it is off, when the handset ist lifted, can
be programmed. Loudspeaker volume can be adjusted with the master volume control.

Microphone Selection
The Major BOS2b2 has three microphone routings available. The PTT button in the handset turns
on the handset's microphone. The red PTT button and the headset's PTT input can be configured
independently. Possible associations are gooseneck microphone, headset microphone or automatic
selection. If automatic selection is on, the headset microphone is used if a headset is detected
otherwise the gooseneck microphone is used.
Tone Call Decoder
The optional software "Encoder/Decoder" allows the Major BOS2b2 to decode Tone Call1 and Tone
Call2 on any radio circuit and to activate the corresponding circuit automatically.
Tone Call Encoder
The Major BOS 2b2 includes a encoder for Tone Call 1 and Tone Call 2. The tone calls are sent with
the corresponding keys of the keypad. The tone is sent as long as the button is pushed.

Please read the operating instructions carefully before installation and setup.
The relevant regulations must be complied to when working with 230V line voltage, two-wire-
lines, four-wire-lines and ISDN-lines. It is also very important to comply to the regulations
and safety instructions of working with radio installations.
Please comply to the following safety rules:
- All components may only be mounted and maintained when power is off.
- The modules may only be activated if they are built in a housing and are
scoop-proof.
- Devices which are operated with external voltage - especially mains voltage -
may only be opened when they have been disconnected from the voltage source
or mains.
- All connecting cables of the electronic devices must be checked for damage
regularly and must be exchanged if damaged.
- Absolutely comply to the regular inspections required by law
according to VDE 0701 and 0702 for line-operated devices.
- Tools must not be used near or directly at concealed or visible power lines
and conductor paths and also not at and in devices using external voltage –
especially mains voltage - as long as the power supply voltage has not been
turned off and all capacitors have been discharged. Electrolytic capacitors
can be still charged for a long time after turning off.
- When using components, modules, devices or circuits and equipment the
threshold values of voltage, current and power consumption specified in the
technical data must absolutely be complied to. Exceeding these threshold
values (even if only briefly) can lead to significant damage.
- The devices, components or circuits described in this manual are only
adapted for the specified usage. If you are not sure about the purpose of the
product, please ask your specialized dealer.
- The installation and setup have to be carried out by professional personnel.
