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.
