<h2>Open a New Throttle Window</h2>
|
|
|
|
<p>This chapter will walk you through the process of opening up a new throttle window and
|
|
then configuring it to run a locomotive on your layout. For the purposes of this user guide,
|
|
we will be using a locomotive that has been equipped with a sound decoder. The decoder's
|
|
address in our examples here is <strong>8251</strong>. If you are following along with a
|
|
locomotive of your own while you read this, simply replace your loco's decoder address
|
|
anywhere that "8251" is shown.</p>
|
|
|
|
<p>So let's get started.</p>
|
|
|
|

<p>The first thing that we want to do is to open up a throttle window. As outlined in
|
|
the <a href="ThrottleChapter1.shtml" title="Go back to review Chapter 1">previous

<h3 id="StructWin">Structure of a Throttle Window</h3>
|
|
|
|
<div style="margin-left: 2em">
|
|
<p>There are <em>three panels</em> (or sub-windows) associated with each Throttle window.
|
|
These are identified as:</p>
|
|
</div>
|
|
|
|
<ul>
|
|
<li><strong>Control Panel</strong> contains a throttle slider to control the speed of the
|
|
loco, a forward and reverse selector, an Emergency Stop action button, and an Idle action
|
|
button (mostly used for sound equipped decoders).<br>
|
|
<br></li>
|
|
|
|
<li><strong>Function Panel</strong> is used to associate the function buttons with the
|
|
active output functions of the decoder.<br>
|
|
<br></li>
|
|
|
|
<li><strong>Address Panel</strong> is used to identify the decoder's address, and to
|
|
dispatch or release the identified address.<br>
|
|
<br></li>
|
|
</ul>
|
|
|
|
<p class="important"><strong>Important!</strong> These three panels are actually windows
|
|
defined within an overall window. Please note that each of these panels contain their own
|
|
"minimize" and "close" buttons - as well as can also be resized. You can actually minimize
|
|
one or more of these panels within the Throttle window. This is being pointed out in event
|
|
that you accidentally click on one of the buttons and the panel disappears on you.</p>

|
|
|
|
<p>Now that we have successfully opened up the throttle window, the next thing we need to do
|
|
is to configure the throttle for operation. We'll do this in two steps. The first will be to
|
|
assign a locomotive's decoder address. Please note in Figure 2-2 above that all of the panels
|
|
are pretty much disabled. This is because there is no address assigned yet. After
|
|
establishing an address, the other options on the panels will become enabled.</p>

<p>The first thing that needs to happen before any options or buttons in the window
|

become active, is to assign a decoder's address in the "<strong>Address

|
|
|
|
<ol>

<li>Manually enter the decoder's address in the large text box, then click on the

<p>Now that you have established an address for the throttle, you should be able to

run the train on your layout (if your layout is active and the address you entered
|
|
is valid to a locomotive on the track). You do this using the "<strong>Control
|
|
Panel</strong>" (see Figure 2-5). But here is where things get a little sticky.</p>
|
|
|
|
<p>There are multiple combinations of DCC systems and computer platforms that make
|
|
up for slight differences in the functionality of the throttles. The programmers
|
|
are working hard at trying to get these throttles to function identically. But
|
|
because of these differences, you may discover that not everything noted in the
|
|
following text will function as defined for your system.</p>
|
|
|
|
<p class="important"><strong>Important!</strong> The "Control Panel" must have the
|
|
"focus" for it to become active (and usable). In other words, it's window bar must
|
|
be active. If you are following along with this text with your own locomotive and
|
|
just entered an address in the Address Panel, you will discover that the Address
|
|
Panel is the window with the current focus. None of the keyboard or mouse actions
|
|
described below will move the train until the Control Panel has the focus. To make
|
|
the Control Panel the active window, use your mouse pointer to click somewhere
|
|
within the Control Panel.</p>

<p style="color: #FF0000; font-size: medium; font-weight: bold">Beware of where you
|
|
click with your mouse pointer in the Control Panel.</p>
|
|
|
|
<ul>
|
|
<li><strong>If you click anywhere near the slider, your loco may take off on you
|
|
unexpectedly (more on this below).</strong>
|

<li><strong>If you click anywhere on the words "Forward" or "Reverse", you will

</ul>
|
|
|
|
<p>So when first clicking in the Control Panel to make it the "active" window with

the focus, and you know that your loco is stopped, it is suggested to click on the
|
|
"Idle" button (if you know for fact that your loco is stopped), or the forward or
|
|
reverse area (depending of course on the current direction of the loco). In other
|
|
words, you want to click somewhere within the border of the Control Panel window,
|
|
yet not cause your loco to do something that you don't want it to do.</p>
|
|
|
|
<p>After a little experimentation, you will discover what is comfortable for your
|
|
usage. The only point we are trying to make here is that many new users immediately
|
|
get frustrated with the throttles because they can't get their loco to move, not
|
|
realizing that the Control Panel does not have the focus. Or they have clicked on a
|
|
function button (more on these below), which then changes the "active" window to
|
|
the Function Panel.</p>

<p>Using the standard key actions are pretty easy. After making the Control Panel have the

the speed on your locomotive. Each click of the <strong>-</strong> key on the numeric

<div style="margin-left: 6em">
|

<p>The slider bar can function differently for each user depending on several factors. This
|
|
user guide is not going to try to identify all of the different possibilities. Instead, it
|
|
is going to identify several of the primary ways that the slider bar can work. At least one
|
|
of these methods should work for you. You may discover that your setup can utilize more
|
|
than one of these. A little experimentation on your part may be required.</p>
|
|
|
|
<ol>
|
|
<li>
|
|
<strong>Slider Method 1</strong>
|
|
<ul>
|
|
<li>Clicking anywhere above the current slider pointer position will INCREASE the
|
|
loco speed by 1 speed step. For example, if the locomotive's current speed setting
|
|
was 23, then a single click will advance the speed to 24. Another click will increase
|
|
the speed to 25. Another click...to speed step 26. Another...to speed step 27. And so
|
|
on...until it reaches the maximum speed steps for your system. This action has the
|
|
same effect as using the <strong>+</strong> key on the numeric keypad.<br>
|
|
<br></li>
|
|
|
|
<li>Clicking anywhere below the current slider pointer position will DECREASE the
|
|
loco speed by 1 speed step. For example, if the locomotive's current speed setting is
|
|
21, then a single click will decrease the speed to 20. Another click will decrease
|
|
the speed to 20. Another click...to speed step 19. And so on...until it reaches speed
|
|
step 0. This action has the same effect as using the <strong>-</strong> key on the
|
|
numeric keypad.<br>
|
|
<br></li>
|
|
</ul>
|
|
|
|
<p class="important"><strong>Note:</strong> Clicking too far below the slider
|
|
(especially when close to the bottom of the slider bar) may not have any effect because
|
|
you are actually clicking on the "Forward" option. Therefore, it is suggested that when
|
|
decreasing speed with this method, that you click on the word "Stop" (not the emergency
|
|
stop button (STOP!) but the word "Stop" located at the lower end of the speed
|
|
slider).</p>
|
|
<br>
|
|
<br>
|
|
|
|
<p class="important"><strong>Note:</strong> If the decoder has acceleration or braking
|
|
rates enabled, the loco will speed up or slow down accordingly. If no momentum values
|
|
are enabled, the loco will speed up or slow down abruptly.</p>

a speed that you wish, and release the mouse button. This will send a "set speed to"
|
|
command to the decoder.</li>
|
|
</ul>
|
|
|
|
<p class="important"><strong>Note:</strong> If the decoder has acceleration or braking
|
|
rates enabled, the loco will speed up or slow down accordingly. If no momentum values
|
|
are enabled, the loco will speed up or slow down abruptly to the speed set when the
|

<strong>Slider Method 3</strong>
|
|
<ul>
|
|
<li>Clicking anywhere above the current slider pointer position will increase the
|
|
slider pointer to the place where the mouse pointer was clicked. For example, if the
|
|
locomotive's current speed setting was around 25% of the slider bar, and the mouse
|
|
pointer was positioned near approximately the 75% point the slider bar when clicked,
|
|
then the speed of the locomotive would be changed to approximately 75%.</li>
|
|
|
|
<li>Clicking anywhere below the current slider pointer position will decrease the
|
|
slider pointer to the place where the mouse pointer was clicked. For example, if the
|
|
locomotive's current speed setting was around 50% of the slider bar, and the mouse
|
|
pointer was positioned approximately around the 25% point on the slider bar when
|
|
clicked, then the speed of the locomotive would be changed to approximately 25%.</li>
|
|
</ul>
|
|
|
|
<p class="important"><strong>Note:</strong> If the decoder has acceleration or braking
|
|
rates enabled, the loco will speed up or slow down accordingly. If no momentum values
|
|
are enabled, the loco will speed up or slow down abruptly.</p>
|
|
|
|
<p class="important"><strong>Note:</strong> Clicking too far below the slider
|
|
(especially when close to the bottom of the slider bar) may not have any effect because
|
|
you are actually clicking on the "Forward" option. Therefore, it is suggested that when
|
|
decreasing speed with this method, that you click on the word "Stop" (not the emergency
|
|
stop button (STOP!) but the word "Stop" located at the lower end of the speed
|
|
slider.</p>

<h3 id="Acquiring">Acquiring a Dispatched Locomotive</h3>

|
|
<div style="margin-left: 2em">
|
|
<p>When the decoder address is first "<strong>Set</strong>", the software queries the
|
|
current status of the decoder. This includes the current direction of the locomotive, its
|
|
current speed, and what function buttons are on or off. The software will set the current
|
|
direction indicator and identify any functions that are "active" (in the "on" state). But,
|
|
if the loco is moving, the loco's speed is not established on the Speed Control slider
|
|
bar.</p>
|
|
|
|
<p class="important"><strong>Note:</strong> At this time, the slider bar does <u>not</u>
|
|
automatically correspond to the actual speed. This is important to understand because of
|
|
what action you are going to see when you first click on the speed slider bar. When you
|
|
first "<strong>Set</strong>" a decoder address, the slider bar is set to the zero (0)
|
|
position. So if you acquired a locomotive that is actually moving and you click on the
|
|
slider bar, it is going to set the speed to zero (or wherever you click and set the slider
|
|
bar pointer).<br>
|
|
<br>
|
|
A future enhancement of the throttle feature will be to synchronize the slider bar pointer
|
|
accordingly. Until then, just beware of this little reaction.</p>

<p>The Function Panel has 28 function buttons available for each throttle window.

Most decoders currently don't handle 28 functions. The function panel displays the

buttons in two groups, press the "*" button in the lower left corner to see the

|
second set of function buttons.</p>
|
|
|
|
<p>Clicking on the function buttons correlate to pressing the same function button
|

on a hand-held throttle. The F0 function is normally used for the lights.</p>
|
|
|
|
<p>This is the basic functionality of the Function Panel. All buttons function like
|

an on/off toggle: click once to turn "on"; click again to turn "off".</p>
