Configuration
The CNDISCO manual (found in the C:\Program Files\Cirrus Logic\CobraNet™
Discovery folder) will explain in detail most of the configuration processes, so these
have not been repeated here. However, there are some useful features of the CobraNet™
protocol that are not covered explicitly, ie…
One of the key features of the STAGE8.8 product is the ability to set up to 4 CobraNet™
audio transmitters and 8 CobraNet™ receivers. In addition, MTS has provided the ability
to set each bundle subchannel configuration.
The settings are:‐
•
Transmitter setup: This section covers the CobraNet™ transmitters (see
Figure
4-2
). The CS496112 chipset allows for up to 4 transmitters, each of up to 8
channels, subject to an overall channel count of 2 analog input channels and 8
network audio streaming channels. The settings are:‐
o
Bundle number: This sets the bundle address of each transmitter. The
bundle numbers are 0 (off, ie no transmission), 1‐255 are multicast, 256‐
65279 are unicast and 65280‐65535 are private.
o
Unicast mode: If the transmitter bundle address is normally unicast
(>255), but more than one receiver is available for that bundle address,
then the bundle can be transmitted either multicast or multi‐unicast.
o
Max Unicast: Depending on unicast mode, the maximum number of multi‐
unicast bundles can be set between 1 and 4.
o
Transmitter1…Transmiter4: This lists the four transmitters associated
with the bundle address and allows the user to set the audio subchannels
associated with that bundle. The subchannel mapping allows the user to
decide which of the 8 audio channels are mapped to each bundle and in
which order they are transmitted.
o
Subformat Resolution: This sets the word length of the transmitted audio
to 16, 20, or 24 bit. Note: if the word depth is set to 24bit, then only 7
audio channels can fit in one bundle.
o
UnicastMode: This value can be used to override or modify the normal
unicast vs. multicast implications of the assigned bundle number. The normal
default value is ‘Never Multicast’. The available options are:
Always Multicast – All bundles are sent multicast regardless of Bundle
number.
