<h1>The Signal Group Table</h1>
|
|
|
|
<p>The Signal Group Table displays a list of your Signal Groups.</p>
|
|
<a href="images/SignalGroupTable.png"><img src="images/SignalGroupTable.png" alt=
|
|
"Tools > Signal Group Table" class="floatRight" width="386" height="168"></a>
|
|
<p>There are six columns in the Signal Group Table:</p>
|
|
|
|
<ol>
|
|
<li>Each line starts with the System Name and User Name of each Signal Group</li>
|
|
|
|
<li>You may add a <strong>Comment</strong> by double clicking on that field</li>
|
|
|
|
<li>The following column contains a <strong>Delete</strong> button for that Signal
|
|
Group</li>
|
|
|
|
<li>By unchecking the <strong>Enabled</strong> check box you can temporarily disable a
|
|
particular Signal Group</li>
|
|
|
|
<li>Finally there is an <strong>Edit</strong> button</li>
|
|
</ol>
|
|
|
|
<h3 id="add">Creating a Signal Group</h3>
|
|
|
|
<p>To define a new Signal Group, click on the <a href="SignalGroupAddEdit.shtml">Add...</a>
|
|
button at the bottom of the Signal Group Table. This will prompt you for a Signal Group name
|
|
and whatever further information is needed.</p>
|
|
|
|
<p>You can delete a Signal Group from the Signal Group Table by clicking one of the
|
|
<strong>Delete</strong> buttons. Save a copy of your JMRI Configuration file as a backup
|
|
first!</p>
|
|
|
|
<h3 id="edit">Editing an existing Signal Group</h3>
|
|
|
|
<p>Click on one of the <strong>Edit</strong> buttons at the right of the Signal Group Table
|
|
to open the <a href="SignalGroupAddEdit.shtml">Edit Signal Group</a> window for the
|
|
corresponding Signal Group. <a href="images/SignalGroup.png"><img src=
|
|
"images/SignalGroup.png" alt="Signal Goup Edit pane" class="floatRight" height="225" width=
|
|
"257"></a></p>
|
|
|
|
<h2 id="example">Signal Group Example - Junction Indicator</h2>
|
|
|
|
<p>Consider the following track diagram, with 6 possible junctions off the main running
|
|
line.<br>
|
|
<a href="images/SignalGroupTrackDiagram.png"><img src="images/SignalGroupTrackDiagram.png"
|
|
alt="Signal Group application example track plan" height="90" width="233"></a></p>
|
|
|
|
<p>The Signal facing this junction will have a Junction Indicator attached, with each
|
|
possible route through the junction having it own Indication. When the Route is set for
|
|
straight through, then no indicator is shown (pictured above).</p>
|
|
|
|
<p>If the route is set for position 1, then the position 1 indicator will be shown (pictured
|
|
below).<br>
|
|
<a href="images/SignalGroupTrackDiagram1.png"><img src="images/SignalGroupTrackDiagram1.png"
|
|
alt="Position indicator on signal" height="90" width="262"></a></p>
|
|
|
|
<p>With this configuration, you would create a single Turnout Signal Head for each position,
|
|
configured with both a Dark and Lunar Appearance. You can use any two combinations of colors
|
|
you like, however Dark and Lunar are more suitable for this situation.</p>
|
|
|
|
<p>Within the Signal Group, you would then select each of the Signal Heads that are used to
|
|
create the junction indicator. The logic for each Signal Head is then configured as
|
|
follows:</p>
|
|
|
|
<table>
