CONFIGURATION
4.3.1 - CLOSED LOOP REDUNDANCY
Closed loop redundancy is supported on Tessera SX40, Tessera S8, M2 and S4 LED Processors
where two outputs can be configured to operate as a redundant pair. Closed loop redundancy is
not supported on Tessera T1 LED Processors as they only feature a single output.
For closed loop redundancy, a cabling loop is created from the prim ary port, through a string of
fixtures, and then back to the processor. One output acts as the prim ary port, while the second
output acts as the backup. In the case of signal loss or errors with the prim ary feed, the backup
port takes control and re-allocates fixtures to use the backup feed. The change is done within
one fram e, ensuring live content continues to display in the event of failures occurring
anywhere in the loop.
Fig 4.1 - Tessera LED Processor setup with redundancy
The load capacity for each redundant pair is the sam e as for a single non- redundant trunk.
Redundancy is only available from port 1 to port 2, and from port 3 to port 4.
Once the system has been cabled correctly, click on the Network pipeline tile. Under
redundancy the user can enable redundancy for connected trunks. The processor is also able to
detect faults with cabling and reports Loop OK or Errors Detected for connected trunks.
