|
<p>For the hard-core programmer, this pane is a listing of the raw CV data by CV number, with
|
|
data in <span class="ACCENT">decimal format</span>. You may change data by typing new numbers
|
|
into the <strong>Values</strong> window. <strong>State</strong> shows the validity of the
|
|
data, whether it was taken <strong>From file</strong> (the decoder information saved in the
|
|
<strong>Roster</strong>), <strong>Edited</strong>, <strong>Read</strong> directly from the
|
|
decoder, <strong>Stored</strong> to the decoder or if the status is <strong>Unknown</strong>.
|
|
Note the <strong>scroll bar</strong> on the right side of the listings. You may scroll up or
|
|
down to access all of the CV listings.</p>
|
|
|
|
<h4>Decoder Locking</h4>
|
|
|
|
<p>You tried to read a CV value and get "Error 308, No Acknowledgement from Decoder", well
|
|
the decoder may be locked. CV 15 and 16 deal with locking, if your manufacturer implements
|
|
this feature (and manufacturers have slight differences as to how they implement it). If the
|
|
decoder is locked, then you will not be able to read data from it or write to it. To unlock
|
|
the decoder, you must enter a value into CV15 (the only CV that can be written when the
|
|
decoder is locked), that is equal to the value that is currently in CV16. Now I hear you
|
|
thinking "but I can't read CV16 to know what to put into CV15". Well, you'll have to try all
|
|
possible values, which isn't that hard since it can only have 8 possible values 0 thru 7.
|
|
After each write, try to read CV16. It's the fastest read since it can only have 8 possible
|
|
values. If JMRI responds with the no-ack error, then try the next value. If it returns the
|
|
value in CV16, you've unlocked the decoder and you're in. If you have unsuccessfully tried
|
|
all the 8 possibilities, then check your layout connection and the loco's wheels for poor
|
|
connections and try again. Now you say, "I've looked thru the list several times and CV 15
|
|
doesn't appear". That's on purpose, to minimize inadvertent locking by a Write All Sheets.
|
|
You will have to use the <a href="Programmer_SingleCV.shtml">Single CV Programmer</a> to
|
|
write CV15. It can be found in the Tools menu on the Main Page, under Programmers.</p>
|
|
|
|
<p>If you have more than one decoder in your locomotive, you probably have a decoder locking
|
|
scheme implemented to be able to access each one individually for programming.</p>
|
|
|
|
<p>You may <strong>Read</strong> or <strong>Write</strong> individual CVs using the buttons
|
|
in their row. On this page, a <strong>Read sheet</strong> or <strong>Write sheet</strong>
|
|
operation is the same as a <strong>Read all</strong> or <strong>Write all</strong>.
|
|
<span class="ACCENT">Again, a reminder: you can only read CVs if your command station has
|
|
that capability.</span></p>

|
|
|
|
<p>One thing to keep in mind about the <strong>CV</strong> listing on this pane - anything
|
|
you can do here you can do from one of the other panes in DecoderPro, without having to know
|
|
the <strong>CV</strong> number or how to compile the values to get the desired effect. This
|
|
pane is meant for advanced users of DCC used to crunching the numbers themselves. Those new
|
|
to DCC can safely ignore this panel without losing any capability at all.</p>
