The Panasonic plasma screens are controlled via a serial port.

Install xPL serial port

Install the serial port driver.

Download the serial port xPL device script. Move it to xPL scripts directory: 

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

Test the serial port device: 

su control
SCRIPTS_BASE_DIR=/home/control/Documents/Controls
ll /dev/tty*
$SCRIPTS_BASE_DIR/xpl-serial_port.pl -v -n loungeScreen -b '\x02' -e '\x03' /dev/ttyUSB0 baudrate 9600 databits 8 parity none stopbits 1 handshake none

Open a 2nd terminal window and test the xPL RS-232 control: 

su control
SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-send.pl -v -d dspc-serPort.loungeScreen -c serPort.basic command=POF
$SCRIPTS_BASE_DIR/xpl-send.pl -v -d dspc-serPort.loungeScreen -c serPort.basic command=PON

Install xPL screen controller

Download the screen controller script. Move it to xPL scripts directory: 

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

Test the screen controller: 

su control
SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-screen-pana.pl -v -n loungeScreen -s loungeScreen

Open a 3rd terminal window and test the commands: 

su control
SCRIPTS_BASE_DIR=/home/control/Documents/Controls
$SCRIPTS_BASE_DIR/xpl-send.pl -d dspc-scrPana.loungeScreen -c screen.basic power=off
$SCRIPTS_BASE_DIR/xpl-send.pl -d dspc-scrPana.loungeScreen -c screen.basic power=on

Launch the scripts at startup

Ubuntu with upStart

Start the serial port and test it: 

su root
service xpl-loungeScreenSerialPort start
service xpl-loungeScreenSerialPort status
initctl list | grep xpl

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

exec $SCRIPTS_DIR/$SCRIPT_NAME $PARAMETERS

Start the screen controller and test it: 

su root
service xpl-loungeScreen start
service xpl-loungeScreen status
initctl list | grep xpl

Debian with SystemD

On Debian with systemd (such as Raspbian), the scripts can be defined as services.

Edit /lib/systemd/system/xpl-screenSerialPort.service: 

[Unit]
Description=serial port for Panasonic screen
After=network.target

[Service]
Type=simple
ExecStart=/home/control/Documents/Controls/xpl-serial_port.pl -n loungeScreen -b \\x02 -e \\x03 /dev/ttyUSB0 baudrate 9600 databits 8 parity none stopbits 1 handshake none -w 2
Restart=always

[Install]
WantedBy=multi-user.target

Activate the service: 

su
systemctl enable xpl-screenSerialPort.service

Reboot and check: 

ps ax | grep -v grep | grep -i xpl
service xpl-screenSerialPort status

Mac OS

Check the serial port device name: 

ll /dev/tty.*
