    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...

    1 = only one channel at a time selected When channels are activated the channel selection LED lights up. If the channel has already been selected by a different Major BOS 8a the device can be programmed so that the corresponding channel selection LED flashes.
  • Page 7 (see section Parallel circuit of several Major BOS 8a). In EEPROM register 025 the loudspeaker switching statuses of the radio channels 1..8 (bit 0..7) can be preselected after turning on the radio installation.
  • Page 8 Loudspeaker (continued) The EEPROM-Register 02A in bit 0 can be configurated so that the receiver AF of all radio channels (without muting) is switched to the loudspeaker or that the corresponding radio channels also have to be activated additionally. register 02A receiver AF on loudspeaker bit 0: 0 = all radio channels without muting...
  • Page 9 Earphones The receiver AF of the selected radio channel can always be heard on the earphones of the handset and the headset. The earphone AF of individual radio channels can be muted either manually by pressing the selection buttons or automatically by transmitting on the active or on one of the other radio channels (earphone muting).

    The volume-controlled receiver AF can be tapped individually for each radio channel on the Major BOS 8a. The outputs can be used e.g. for connecting external AF-amplifier. The receiver AF (RX-AF outputs) of individual radio channels can be muted either...

  • Page 11: External Signalling Device

    - the PTT2 input can be programmed as headset detection (programming register 04C) - the Major BOS 8a can detect if a headset is connected by measuring the headset supply voltage (programming register 051/052). The threshold level in register 051 has to be set so that the measured supply voltage (at ST10 between Pin 2 and 5) without headset is higher and with headset is lower than the threshold level.

  • Page 12: Opto-Coupler Input

    Opto-Coupler Input The Major BOS 8a has an opto-coupler input at connector ST14a. This opto-coupler input can be programmed with different functions. a) If this register is encoded to value ´00´, the opto-coupler input switches the handset/ headset to the audio-frequency-connection when activated (standard function, see section Connection to Telephone AF).

  • Page 13: Connecting Several Major In Parallel Circuit

    Connecting several Major in Parallel Circuit As the AF outputs are only open during transmission and the AF inputs can be switched to high-resistance by pulling the jumpers J1 to J4, it is possible to connect several Major BOS 8a in parallel. Therefor, all connections to the single radio circuits (TX-AF, RX-AF, squelch and transmitter PTT) have to be connected in parallel (bus- or hub-wiring).

  • Page 16 Universal-encoder/decoder-module UGA00. The status of the switching outputs DEC1 and DEC2 of all UGA-modules is transmitted to the Major BOS 8a and causes the loudspeaker-AF of the corresponding radio channels to be turned on(if it was turned off before): a) If the switching output DEC2 is turned on because of the UGA-decoding, then the loudspeaker-AF of the corresponding radio channel is turned on permanently.
