1 for 2 Redundancy
For 1:2 switched redundant operation, three Converter units are required along with typically an
R2000HH external switch unit for receiver units, T2000HH external switch unit for transmitter
units.
In use, the redundancy type on the configure/ redundancy menu is set to 1:2 and units set to
identifier “A”, “B” or “S”. The switch unit is connected to the rear panel 9 way connector with the
supplied cables. A changeover will be caused by an alarm detected in one of the online units
(“A” or “B”) or a changeover (keypad 4) being selected, this will result in the configuration of the
online unit being taken over by the standby and then the standby will take over the RF path,
making itself the online unit.
1 for N Redundancy
For 1:3 to 1:8 switched redundant operation the RCU1000 series of redundancy units are
available, see data sheets for specifications.
