11.3.2 5949 Connections to the Audio Crosspoints
The 5949 video output module receives two identical multiplexed audio transport streams,
each of which contains all of the audio channels on the output module (up to 768 mono
channels). One transport stream is received from the main audio crosspoint module and a
duplicate transport stream is received from the redundant audio crosspoint module. The
output module monitors the transport streams received from each of the audio crosspoint
modules for errors. If an error is found the output module will use the transport stream from
the other audio crosspoint module if it is fitted.
11.3.3 5949 Output Module LED Information
Table 47 shows the LED color code on the 5949 Output Module, and Figure 125 shows the
front edge of the output module.
Important:
•
Due to the nature of multiplexed audio transport streams there is an extremely
small delay between groups of channels as the transport stream is constructed. If
the audio is locked to the input these delays will need to be considered.
•
If the audio is locked to an external reference these delays are managed by the
router and the audio will remain co-timed.

Each Pair of FPGA LEDS:
Flashing rapidly between Red & Green
(2 Hz each LED) - starting up

Green Off & Red On Solid - FPGA
programming fault found. Remove module
and refit to force a reboot.
Red & Green Flashing very rapidly in
sync
(4 Hz each LED) - A change has
been made to the module settings
database in RAM but it has not yet been
written to flash memory. This is not a fault
and the flash memory will be updated
after 10 seconds of no audio setting
changes being made. Do not remove
power from the module while this
indication is present as the flash may
become corrupted.
Other indications are displayed when
performing a firmware upgrade, see the
Sirius 800 Maintenance & Upgrade
manual for details.
