Control
The
DXE-RR2X8B
allows the user to switch inputs from either Main or Secondary to the eight
output ports using 1 of 8 logic inputs. The logic high required for switching is +12 Vdc.
When selecting the various switch positions, the Main has precedence. This means if the Main selects
output port #3, the Secondary cannot use port #3 at the same time.
Secondary will then be transmitting to an open
Another example would be if the Secondary has selected port 5 and you are transmitting, and the Main
then selects port 5, the Main takes port 5 and Secondary will then be transmitting into an open.
A
very simplified
schematic is shown:
Main selection always takes precedence.
Main and Secondary can never use the same
output port at the same time (See notes above).
(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.
