TX500 series technical manual
9.6.1.1 Mode 1 - <EXT-FIXED>
In this mode all assignments to channels are made separately using a channel assignment
panel connected to one of the panel ports on the Aurora controller. This panel should be
configured to use video and audio panels with the same suite numbers as the ‘pres panel’.
Any assignment to channels made from this panel will then be reflected on the TX 510.
9.6.1.2 Mode 2 - <EXT AUTO>
In this mode the assignments to the channels are set as described for the Ext Fixed mode,
via a channel assignment panel, however they are not fixed. The TX 510 will assign a
source to a channel, if the source requested on the automation port is not currently assigned
to the panel.
When a command to set a channel, on a bus is received from the automation port, the
channel number is assumed to be equal to the association number on Aurora. This source
association number is assigned to a channel. The video and audio suites are expected to
have the same panel assigned and will always have the same source association assigned
for both video and audio.
When a source is requested via the automation port, the TX 510 will check the source
association against those sent by the system controller and if found, the matching channel
will be used. If it is not found, then the highest unused channel will be assigned that source
association. The maximum number of channels that can be automatically assigned is 8
(channels 5 to 12). These sources are assigned from the right hand side of the mixer bus.
It is also possible for the automation system to remotely assign source associations to
channels, this is detailed in SW-P-32 (Automation Control Protocol).
