<p id="siteSub">PC Control Groups can be used to monitor
and control groups of control parameters i.e. mutes, faders
and so on, within the system. Each PC control group can
be associated with any number of control parameters which
are of the same type and in the same range. The PC control
group exposes a single control which can be placed on
a custom control panel. The value of this control is determined
by the values of the control parameters in the group.
The PC must be online to the system in order for the control
panels to be monitored. This is a useful feature where
there are 2 London devices performing the same action
(dual redundancy) since the PC control group will allow
you to monitor and control the same control parameters
on each London device.</p>

<h2>Creating a PC Control Group</h2>
<p>There are 2 ways in which to create a PC control
group.</p>
<p>&#160;<br>
1. <span class="hcp1">Create an empty
PC control group</span> by selecting it from the Panel
Menu. This displays the following dialog:</p>
<p>&#160;<br>
<img src="Create_pc_control_group.jpg" alt="Image:Create pc control group.jpg" title="Image:Create pc control group.jpg" style="border-width: 2px;
border-style: solid; margin-top: 0px; margin-bottom: 0px;
margin-left: 0px; margin-right: 0px;" width="380" height="421" border="2"></p>
<p>&#160;<br>
To then add controls to this group, drag the control
and drop it onto the control group which can be found
in the design tree under &quot;This Computer&quot;</p>
<p>&#160;<br>
2. <span class="hcp1">Create a PC Control
Group from selected objects.</span> This creates a
PC Control Group and adds all of the selected parameters
on the active control panel to it. The same dialog
as above is presented except the mode will already
have been determined. If any of the selected parameters
are read only then the PC Control Group is automatically
set as read only and cannot be changed.</p>
<p>&#160;</p>
<ul>
<li class="p"><p><span class="hcp1">Name
of PC Control Group:</span> Set a name for the
PC Control Group. It will then appear in the This
Computer folder in the <a href="MAINDesign_tree.htm">Design
Tree</a>. Drag it from the design tree and drop
it onto a control panel to control and monitor
the controls in the group. Selecting the control
group in the design tree will cause a green box
to be displayed around all of the controls in
that group to easilly identify its members.</p></li>
</ul>
<p>&#160;</p>
<ul>
<li class="p"><p><span class="hcp1">Force
PC Control Group to be read only:</span> Check
this box to set the exposed parameter as read
only. If any of the parameters in the group are
read only then this box will always be checked
and cannot be unchecked.</p></li>
</ul>
<p>&#160;</p>
<ul>
<li class="p"><p><span class="hcp1">Ignore
offline parameters:</span> Check this box for
the exposed parameter to ignore any parameters
which exist on devices which are no longer online
(the controls would appear greyed out on a control
panel).</p></li>
</ul>
<p>&#160;</p>
<ul>
<li class="p"><p><span class="hcp1">Binary
Mode:</span> Select binary mode when the parameters
in a group are on/off such as mutes, which would
normally be represented as buttons on a control
panel.</p></li>
</ul>
<p>&#160;</p>
<ul>
<li class="p"><p><span class="hcp1">Continuous
Mode:</span> Select continuous mode when the parameters
in the group have a range greater than on or off.
Note however, that controls must be in the same
range as each other in order to be in the same
control group.</p></li>
</ul>
<p>&#160;</p>
<ul>
<li class="p"><p class="hcp2"><span class="hcp1">Value changes:</span>
Sets the conditions for a change in the exposed
parameter.</p></li>
<li class="hcp3"><ul>
<li><p class="hcp2"><span class="hcp1">when
all parameters are equal</span> sets the exposed
parameter to the value of the parameters in
the group when they are all equal.<br>
</p></li>
<li><p class="hcp2"><span class="hcp1">to
value of last changed parameter</span> sets
the exposed parameter to the value of the
last parameter in the group to have changed.<br>
</p></li>
<li><p class="hcp2"><span class="hcp1">to
on when all parameters are on</span> sets
the exposed parameter to ON only when all
the parameters in the group are ON. The exposed
parameter will be OFF when all of the parameters
in the group are OFF. This applies to button
mode only.<br>
</p></li>
<li><p class="hcp2"><span class="hcp1">to
ON when more than X controls are ON</span>
sets the exposed parameter to ON when more
than X number of parameters in the group are
set to ON. The value for X is set in the &quot;where
X is&quot; edit box. This applies to button
mode only.<br>
</p></li>
<li><span class="hcp1">to average
of all parameters</span> sets the exposed
parameter to the average of all the parameters
in the group. This applies to fader mode only.</li>
</ul></li>
</ul>
<p>&#160;</p>
<ul>
<li class="p"><p><span class="hcp1">Where
X is:</span> Enter a value for the number of parameters
which must be ON before the exposed parameter
goes ON. This only applies when the <span class="hcp1">Value
changes</span> box is set to &quot;<span class="hcp1">to
ON when more than X parameters are ON</span>&quot;.</p></li>
</ul>
<p>&#160;</p>
<ul>
<li class="p"><p class="hcp2"><span class="hcp1">When value changes:</span>
Determines the action to be taken on the parameters
in the group when the exposed parameter is changed.
This option is not available for read only PC
Control Groups.</p></li>
<li class="hcp3"><ul>
<li><p class="hcp2"><span class="hcp1">send
inverted current state</span> sets all parameters
in the group to the inverted value of the
exposed parameter. This applies to button
mode only.<br>
</p></li>
<li><p class="hcp2"><span class="hcp1">always
send off</span> sets all parameters in the
group to OFF. This applies to button mode
only.<br>
</p></li>
<li><p class="hcp2"><span class="hcp1">always
send on</span> sets all parameters in the
group to ON. This applies to button mode only.<br>
</p></li>
<li><span class="hcp1">maintain
offsets</span> sends the change in the exposed
parameter to all the parameters in the group
therefore maintaining offsets between parameters
in the group. This applies to fader mode only.</li>
</ul></li>
</ul>
