The central xPL device can be compared to a central station. It monitors all xPL messages and can trigger other messages based on a set of rules stored in an XML file.

Before all,make sure you have installed an xPL hub.

Install xPL central device

Install XML::Simple:

su
perl -MFile::Find=find -MFile::Spec::Functions -Tlw -e 'find { wanted => sub { print canonpath $_ if /\.pm\z/ }, no_chdir => 1 }, @INC' 2> /dev/null | grep -i 'xml.*simple'
perl -MCPAN -e "install 'XML::Simple'"
exit

If XML::SAX::Expat doesn't install properly and blocks the installation of XML::Simple, which was the case on my Ubuntu BeagleBone, try:

su
apt-get install libxml-sax-expat-incremental-perl
ln -s /usr/share/perl5/XML/SAX/ParserDetails.ini /usr/local/share/perl/5.14.2/XML/SAX/ParserDetails.ini
perl -MCPAN -e "install 'XML::Simple'"
exit

Download the xPL central device script.

Move the script to xPL scripts directory:

SCRIPTS_BASE_DIR=/home/control/Documents/Controls
mv xpl-central.pl $SCRIPTS_BASE_DIR
chown control:users $SCRIPTS_BASE_DIR/*.pl
chmod 775 $SCRIPTS_BASE_DIR/*.pl

Test xPL central device

Test it on a BeagleBone:

su control
SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-central.pl -h
$SCRIPTS_BASE_DIR/xpl-central.pl -v -n home

Edit /home/control/Documents/Controls/centralActions.xml:

Open a 2nd terminal window (on any machine with xPL installed) and monitor the xPL protocol:

SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-monitor.pl -vf

The monitor should echo the serial port incoming messages.

Open another terminal and send a message to the serial port:

su control
SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-send.pl -v -t cmnd -d dspc-serPort.test -c serPort.basic command='hello world'

Launch the xPL central device at startup

The xPL central device is to be launched after the xPL hub.

Ubuntu

On Ubuntu, the xPL central device starts-up once xpl-hub_started has been emitted.

Edit /etc/init/xpl-central.conf:

################################################################################
# xPL central message parser
#
description "xPL central message parser"
version     "1.0"

#

# Start daemon

exec $SCRIPTS_DIR/$SCRIPT_NAME $PARAMETERS

Start the device and test it:

su root
service xpl-central start
service xpl-central status

SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-send.pl -v -t cmnd -d dspc-serPort.eib -c serPort.basic command='gci'
$SCRIPTS_BASE_DIR/xpl-send.pl -v -t cmnd -d dspc-serPort.eib -c serPort.basic command='dts \$15'
$SCRIPTS_BASE_DIR/xpl-send.pl -v -t cmnd -d dspc-serPort.eib -c serPort.basic command='tds (1/1/1) 1'

Mac OS

On Mac OS, the xPL central device starts-up later than the hub.

Edit /Library/LaunchDaemons/xpl-central.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

Start the device and test it:

su root
launchctl load /Library/LaunchDaemons/xpl-central.plist

SCRIPTS_BASE_DIR=/Users/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-send.pl -v -t cmnd -d dspc-serPort.eib -c serPort.basic command='gci'
