<h2>What is the BLU-8?</h2>

<p>The BLU-8 sits in the product range between the <a href="BLU-3-BLU-6.html">BLU-3</a>

<h2>BLU-8 Network operation</h2>
|
||
|
|
<p>The BLU-8 is <span class="hcp2">not</span>
|
||
|
|
designed to work on a network with CobraNet traffic. BSS
|
||
|
|
recommends that CobraNet traffic is transferred on a separate
|
||
|
|
network to the HiQNet control network.</p>
|
||
|
|
<p>The BLU-8 is capable of handling the following simultaneous
|
||
|
|
communications :</p>
|
||
|
|
<ul>
|
||
|
|
<li class="p"><p class="hcp1">Communication
|
||
|
|
with a maximum of 8 HiQNet devices from all the pages
|
||
|
|
configured on the BLU-8, PLUS</p></li>
|
||
|
|
<li>Communication with one programming device (London
|
||
|
|
Architect).</li>
|
||
|
|
</ul>
|
||
|
|
<p> <br>
|
||
|
|
For optimum performance, the BLU-8 should be used on a
|
||
|
|
dedicated Soundweb London control network with only one
|
||
|
|
instance of HiQnet London Architect present. In this condition
|
||
|
|
the BLU-8 can be used to control the parameters of up
|
||
|
|
to a maximum of 8 other HiQNet devices. It should be noted
|
||
|
|
that as the network on which the BLU-8 resides becomes
|
||
|
|
large, the responsiveness of the BLU-8 can be adversely
|
||
|
|
affected by the volume of network traffic and as such,
|
||
|
|
controls may become slower to respond.</p>
|
||
|
|
<p>If responsiveness is an issue then please follow the
|
||
|
|
recommendations below to improve the situation :</p>
|
||
|
|
<p> <span class="hcp2"><br>
|
||
|
|
RECOMMENDATIONS :-</span></p>
|
||
|
|
<ul>
|
||
|
|
<li class="p"><p>No CobraNet traffic on the part of
|
||
|
|
the network with the BLU-8. (CobraNet traffic swamping
|
||
|
|
the network WILL affect the responsiveness of the
|
||
|
|
BLU-8).</p></li>
|
||
|
|
<li class="p"><p>Use switches rather than hubs in your
|
||
|
|
network implementation.</p></li>
|
||
|
|
<li class="p"><p>One London Architect PC active on
|
||
|
|
the network at a time.</p></li>
|
||
|
|
<li class="p"><p class="hcp1">Minimise
|
||
|
|
unnecessary 'broadcast' traffic reaching the BLU-8,
|
||
|
|
the following two steps are aimed at reducing this
|
||
|
|
traffic :</p></li>
|
||
|
|
<li style="list-style: none; display: inline;"><ul>
|
||
|
|
<li class="p"><p class="hcp1">Ensure
|
||
|
|
that all the HiQNet devices on the network are
|
||
|
|
included in the London Architect design. If they
|
||
|
|
are not part of the design then they can be powered
|
||
|
|
off to reduce unnecessary traffic on the network.</p></li>
|
||
|
|
<li>If there are many devices on the network which
|
||
|
|
the BLU-8 does not need to communicate with, then
|
||
|
|
consider placing these devices on a different
|
||
|
|
sub-net to the BLU-8 (on the other side of a network
|
||
|
|
router). The <a href="Using HiQnet London Architect Across a VPN.html">Static
|
||
|
|
Routes</a> feature in London Architect can be
|
||
|
|
used to ensure that the BLU-8 is discovered by
|
||
|
|
London Architect even if the London Architect
|
||
|
|
PC is on a different sub-net to the BLU-8.</li>
