Programming Example:
radio circuits 1-6: analogue, radio circuit: 7-8 digital
Only the circuit of the current conversation is to be heard on the loudspeaker
register 020: C0
register 021: 00
register 054: C0
The values to program in all 3 registers are calculated as follows:
circuit 1: 1
circuit 2: 2
circuit 3: 4
circuit 4: 8
The numbers of all selected circuits have to be added and the result is programmed in the
second digit of the register.
circuit 5: 1
circuit 6: 2
circuit 7: 4
circuit 8: 8
The numbers of all selected circuits have to be added and the result is programmed in
the first digit of the register.
Numbers 10-15 are programmed as letters A-F (10=A, 11=B, 12=C,13=D, 14=E, 15=F).
Switching Matrix for Circuit Forwarding
(optional)
The additional functions for radio circuit forwarding are controlled by long pressing of
the the circuit's selection and loudspeaker buttons. MBOS 8a allows to transmit an
incoming AF of one circuit to the same (RS1) and/or to any other circuit (RS2). Here,
only one channel is receiving in order to avoid feedback. Controlling the transmitter can
be done by carrier or by AF with a delay time. After decay of the carrier or at the end of
the AF decay time the transmitters are turned off and the initiation of new forwarding is
blocked for a programmable time
The circuits that are acitvated for forwarding are indicated by fast flashing of the lower
volume LED. Long pressing of the selection buttons toggles the status of the circuit
from forwarding active (LED flashes) to forwarding off (LED on or off depending on
the volume). Long pressing of a loudspeaker button activates a combination of circuits
defined in the EEPROM. At least one of the loudspeaker buttons should be programmed
with '00' to be able to turn off all active forwarding operations.
Current forwarding is indicated on the display by fast flashing of the transmission LED.
The programming of all parameters is acheived form the PC via the RS 232 interface
using a terminal program. The EEPROM registers > 100 are adressing the EEPROM on
the switching matrix board.
The RS1 function is active if exactly one circuit is active for forwarding and the
respective BIT in register 113 is programmed properly. If the corresponding BIT in
register 112 is programmed, forwarding of this circuit to all other circuits always results
also in forwarding to the original circuit (RS1).
