Major BOS 8a
Major BOS 8a
is a µC-controlled desktop controller unit for 2-way radio systems controlling
up to eight radios. Different operating parameters can either be factory preset or programmed
during installation.
Connectivity
For operation 12 V DC power supply is necessary. Up to eight channels (radio sets, PA
systems -/intercom etc.) can be connected, also an external handset/headset, up to two
external monitoring-interfaces (
TBBox4
), an external signalling device, a tape recorder
and a AF-RX-amplifier for each channel.
Furthermore there is a RS232-connection, to which a terminal can be connected, or a PC
for external control.
There is a squelch input for each radio and also a PTT output, a busy-line,an AF-input and
AF-output. As the TX-AF-outputs are only active while transmitting, several
