<p>The <strong>Multi-Programmer Control</strong> provides a convenient way to program CV's
|
|
when you have more than one decoder installed in a locomotive. For example, if you have
|
|
separate decoders to control the motor and provide sound, and they both use the same CV
|
|
locations, programming one decoder would change the settings on the other, usually an
|
|
undesired feature.</p>
|
|
|
|
<p>This control uses CV15 and CV16 to control writing and reading CV values. Prior to
|
|
installation of the decoders into the locomotive, each one would have a separate and specific
|
|
value programmed into CV16</p>
|
|
|
|
<p>Recommended values:</p>
|
|
|
|
<ul>
|
|
<li>motor decoder value of 1</li>
|
|
|
|
<li>sound decoder value of 2</li>
|
|
|
|
<li>function only decoder value of 3</li>
|
|
|
|
<li>other uses values of 4 thru 7</li>
|
|
</ul>
|
|
|
|
<p>Decoders should ship with the value of 0 in both CV15 and CV16, You can only perform a
|
|
read or write operation on the decoder if CV15 and CV16 are the same value. In effect, CV16
|
|
is a lock and CV15 is the key. Once the decoder is locked in this way, the ONLY CV that can
|
|
be programmed is CV15 (you do need to be able to unlock it).</p>
|
|
|
|
<p><br>
|
|
So now you have two decoders with the same address (both of them locked) and you want to
|
|
unlock one of them. The Multi Decoder Control is the tool for that.</p>

|
|
<p>If you followed the recommended values we talked about above, then you know what the
|
|
un-lock number is. The <strong>ID number</strong> buttons numbered 0 thru 6 let you
|
|
select the value to be entered into CV15 that will unlock the decoder with the
|
|
corresponding number in its lock (CV16).</p>
|
|
|
|
<p>DecoderPro then reads back the value in CV16 to confirm that the decoder has
|
|
successfully unlocked.</p>
|
|
|
|
<p>Once you are done with your programming the tool can again be used to insert a zero
|
|
into CV15, thereby locking this decoder.</p>
|
|
|
|
<p>The <strong>Legacy</strong> button writes a 7 to CV15, which is a special case. Many
|
|
decoders, especially older models, do not have this locking mechanism present. In some
|
|
cases, specifically a Digitrax FX3 or later decoder and an early SoundTraxx decoder,
|
|
it's possible to emulate the lock using sequential writing of the CVs. Clicking the
|
|
<strong>Legacy</strong> button activates this procedure. Unfortunately, it's not an
|
|
entirely reliable method.</p>
|
|
|
|
<p>But, what if you didn't follow the recommendations? The <strong>Search</strong>
|
|
button sequentially works through the possible values and marks values found to be
|
|
present. If you're dealing with a single decoder to unlock, than you're home free. If
|
|
we're talking about multiple decoders with the same address we're probably going to get
|
|
more than one value marked. It's up to you to figure which is which. One way is by
|
|
changing the address of one and then testing to see what action changed with the new
|
|
address.</p>
|
|
|
|
<p><strong>Search</strong> button sequentially works through the possible addresses and
|
|
marking those decoder addresses that are found to be present.</p>
|
|
|
|
<p><strong>Reset</strong> button looks for possible combinations to unlock a decoder
|
|
that has been inadvertently locked. <span class="ACCENT">Only use this option if you
|
|
have just one decoder in the locomotive. If you have more than one , it will unlock all
|
|
of them, which may cause confusion later.</span></p>
|
|
|
|
<p><strong>Init DH163 + SoundTraxx</strong> button configures the
|
|
<strong>Legacy</strong> mode discussed above.</p>
|
|
|
|
<p>Status message are displayed below the buttons, shows <strong>idle</strong> when no
|
|
action is occurring.</p>
|
|
|
|
<p>At the bottom of the window you can select the Programming Mode. Any mode not
|
|
supported by your command station will be grayed out.</p>
|
|
|
|
<p>If you select the <strong>Ops</strong> mode, which programs on the main track, you
|
|
need to enter the address of the decoder (locomotive) that you are programming. Your
|
|
DCC system may require you to check the <strong>Long address</strong> check box if the
|
|
address is a long address.</p>
