Very
Simplified
Control Logic
When selecting the various switch positions, the first control console that selects a particular position
has precedence. This means if Radio “A” selects output port #3, them Radio “B” cannot use port #3 at
the same time. Radio “B” will not connect to port #3. The operator will know that there is no antenna
selected since there will be no audio from any signals coming into Radio “B”.
A
very simplified
schematic is shown:
Master Radio “A” and Slave Radio “B” can never use
the same output port at the same time.
(Ports not selected are grounded)
Caution:
Never switch antennas while transmitting. Hot switching with power will create a
sustained arc that damages relay contacts.
When switching ports, allow 15 ms before transmitting
to avoid damaging the switch. This type of damage is
NOT
covered under warranty.
