|
<p>The "OpenLCB Hub Control" tool enables a physical OpenLCB connection to be shared on a
|
|
Network Connection.</p>
|
|
|
|
<p>The window displays the IP address and port of the Hub, along with client connection and disconnections.</p>
|
|
|
|
<p>If IP addresses are flagged as Loopback or LinkLocal, this is indicated.</p>
|
|
|
|
<p>The OpenLCB Hub can be opened by adding as a system startup action.</p>
|
|
<p>This page can be opened from the Hub Control via Help > Window Help .</p>

<p>You should not normally need to change these settings, however if you do so, you are advised to restart JMRI.</p>
|
|
|
|
<h4>Send Line Termination</h4>
|
|
<p>Hub sends CAN Frames in the GridConnect Serial format, and when Send Line Termination is enabled ( OpenLCB default ),
|
|
is followed by a line termination character ( CR/LF ).</p>
|
|
|
|
<h4>Require Line Termination</h4>
|
|
<p>When unchecked ( default ), Hub reads the GridConnect content between the start of the Serial Format
|
|
" <code>:</code> ", and end of format " <code>;</code> " characters.
|
|
<br>Any other characters, including line termination characters are silently ignored.</p>
|
|
<p>When enabled, Hub receives CAN Frames whenever a line termination is received in the network stream.</p>
|
|
|
|
<h4>Also see</h4>
|
|
|
|
<p>The Grid Connect Serial specification is the documentation for their CANUSB Interface,
|
|
see section 2.7.1 Message String Syntax in the pdf at

|
|
<br>Line terminations can be enabled / disabled in this USB devices output via a device setting.</p>
