<h1>JMRI: System Console</h1>
|
|
|
|
<p>The JMRI System Console panel is where you get system output from JMRI.</p>
|
|
<!-- Copied from NCE help -->

<h2>Using the System Console</h2>
|
|
|
|
<p>JMRI provides connection information via the system console. You can find the system
|
|
console under the main menu header "Help" then "System Console...". Below is an image of the
|
|
console window when the program is operating normally. Note that the window size has been
|
|
adjusted so we can read it a bit more easily.</p>

|
|
<p>If you're having problems, the console window can look like the one below:</p>
|
|
|
|
<p><img src="../../html/hardware/images/jmriConsoleFail.jpg" alt="JMRI Console">
|
|
</p>
|
|
|
|
<p>To help you better understand what might be happening and to possibly resolve your problem
|
|
we'll explain some of the warning and error messages displayed in the above console
|
|
window.</p>
|
|
|
|
<p>The very first messages are information message labeled "INFO". The first message occurs
|
|
at time "0" which can be found at the left side of the message. The next "INFO" message
|
|
states where this log file is stored. The next info provides the version of JMRI and JAVA
|
|
that you are using. And the last info message provides the communication port that you've
|
|
selected in preferences, along with the baud rate or the speed of your connection.</p>
|
|
|
|
<p>The first warning message states that there was a timeout to message "AA". During startup,
|
|
JMRI checks to see if your Preferences match those in the NCE command station. Message "AA"
|
|
requests the EPROM revision of the command station. The response is normally three
|
|
characters, something like "6.2.1". A timeout means that JMRI asked for something and the
|
|
command station didn't respond. When the connection is correct and the system is powered up,
|
|
you should not see any timeout messages.</p>
|
|
|
|
<p>The next warning message states that because there was a timeout, the program didn't get
|
|
the information requested from the command station. The next messages continue as the program
|
|
tries every 10 seconds to read the EPROM revision by issuing the "AA" command. You can try
|
|
and trouble shoot your connections knowing that every 10 seconds JMRI will retest to see if
|
|
you've fixed the problem.</p>
|
|
|
|
<p>Whenever JMRI detects a problem with the connection or NCE command station, it will
|
|
request the EPROM revision to see if the connection and command station is still operational.
|
|
So if you see timeouts and "AA" commands you have either poor or failed connection, or a
|
|
powered down or failed command station.</p>
|
|

|
<p>See <a href="../../html/doc/Technical/Logging.shtml">JMRI Logging</a> for details of how to change the logging levels.</p>
