<h1>Hardware Support: Speedometers</h1>
|
|
|
|
<p>JMRI supports the Bachrus MTS-DCC Model train Speedometer,
|
|
and the KPF-Zeller Speedometer, which are input-only devices,
|
|
to capture speed information from a locomotive on a running stand.</p>

<h2 id="usage">Usage</h2>
|
|
|
|
<p>When a speedometer is set as a JMRI Layout Connection Preference, the Speedo Console
|
|
tool can be used to display scale running speed for any scale from Z to O and beyond.</p>

|
|
<p>When a speedometer is set as a layout connection alongside a DCC hardware system the
|
|
speedo utility allows automated measurement of a DCC decoder equipped loco's speed
|
|
profile.</p>
|
|
<a href="images/profile.jpg"><img src="images/profile.jpg" width="543" height="373" alt=
|
|
"Speedometer speed profile graph"></a><br>
|
|
Right hand side of Speedo panel
|
|
<p>
|
|
At the bottom of the right side is a "Speed Matching" section.
|
|
This configures the Vstart (3) and Vhigh (4) CVs to match the
|
|
your desired speeds at speed step 1 and 28.
|
|
The Vmid CV is set to half way between these to attempt
|
|
to set a straight-line speed curve.</p>
|
|
<a href="images/SpeedMatchSection.png"><img src="images/SpeedMatchSection.png"></a>
|
|
<p>
|
|
Note that after these CVs have been set by running the matching,
|
|
you should go to the DecoderPro roster entry for this decoder
|
|
and do a "Read Full Sheet"
|
|
of the "Basic Speed Control" pane to capture the new values.
|
|
<p>
|
|
If you are doing this on the the programming track,
|
|
the process will have set the momentum CVs to zero and restored them on
|
|
successful completion. This is done
|
|
to avoid them interfering with the matching process. If you're programming
|
|
on the main track, this step is skipped. In that case, make sure that you
|
|
have set the momentum CVs to zero before starting the process, and
|
|
restore them manually afterwards.
