<h1 class="firstHeading">CobraNet Tab</h1>
<p style="font-size: small;"><img src="CobranetTab.png" style="border: none;" alt="" border="0"></p>
<p class="hcp1">These settings are for the network audio behaviour
of the design file. The CobraNet bundle start numbering can be adjusted
here (default is 1000).</p>
<p class="hcp1">The default audio sample rate across the network
can be set here (choose between the standard 48kHz and the higher quality,
but higher overhead, 96kHz). As new BLU processors are dragged into the
design they will take their default sample rate from this setting. However,
devices can be run at the other sample rate as long as they are only connected
to other processors using the same sample rate.</p>
<h2><span class="hcp2">Latency</span></h2>
<p class="hcp1">There is also a selection of 3 possible latency
settings, this is the finite time that audio takes to pass thru a network
device and, if much processing is involved this can very slightly delay
the audio in the system. The maximum latency incurred in a CobraNet network
is 256 samples (5-1/3ms) at the receiving CM-1 card. This latency can
be reduced at the expense of CobraNet audio channels transmittable from
device to device and all units on the network must be configured to operate
at this latency.</p>
<span class="hcp2">NB:</span>
<br>If 96kHz is chosen the number of usable channels per
bundle falls from 8 to 4 if using a latency of 5 1/3ms, as shown in the
info box below. Shortening the latency will bring the channel count back
up to 8.
<p class="hcp1">This capability will be borne out so long as
fewer than 6 switch hops are used on a 100BaseT network. Greater than
6 switch hops may incur more delay. On a Gigabit network you may be able
to have 15 switch hops before incurring additional delay.</p>
<p class="hcp1">A CobraNet network utilising the CM-1 module
can make use of a number of possible latency times and sample rates.</p>
