INTRODUCTION
The purpose of this document is to describe how the external control interface of the device works.
HOME AUTOMATION SYSTEM INTEGRATION
The Model P200 is compatible with home automation systems via the RS232 and network connectors
on the rear socket panel. The P200’s IR and trigger connections can also be programmed for use in a
home automation system.
CONTROL VIA NETWORK
Open a TCP connection on port 84 and use the control protocol as described in this document. For
control from a PC, use Telnet, Putty, or similar programs to open the TCP connection.
If you do not know the IP address of the Model P200 on your local network, the Model P200 supports
Apple´s Bonjour Discovery service, which must be on the computer you want to set up the Model
P200 with. The software is built-in as part of the Apple OS X operating system. For Windows
operating systems, the software can be found at http://www.apple.com/support/bonjour/
The control protocol is announced via bonjour as the service “_slactrl”.
Pressing the “OK” button on the remote and toggling through the “Info” of the unit will also display the
current IP address of the unit.
The P200 can also be controlled via the network by accessing http://p200.localin your browser.

5
CONTROL VIA SERIAL PORT
The serial port on the P200 is wired as a DTE, so for communication with a PC or similar, you will
need a null modem adapter and gender changer.
The port settings should always be 8 data bits, no parity, one stop bit and no hardware handshake.
The baud rate is 115200 bits per second. All commands and responses are in ASCII form.
When controlling the P200 via the serial port, it is able to wake up even when the standby mode has
been set to “deep sleep”. However, the P200 will miss the first one or two characters transmitted
when in deep sleep, because it needs to wake up first. So in order to make sure the P200 is ready for
the command, send a few extra characters before an ON-command. Sending for instance
“!!!POWERONMAIN” to turn on the P200 will guarantee that the command is always received, even if
it is in deep sleep.

CONTROL PROTOCOL
Commands
Every command starts with ‘!’ character and ends with carriage return (ascii 0x0D, referred to in this
document as <CR>). There are two types of commands, commands and status requests. Commands
are used to emulate remote key presses or to set a certain volume etc. Status requests are used to
query the current state of the controller (volume, current source etc.). Commands with invalid format
are simply ignored. For example, sending a command !VOL(100)garbage!MUTEON<CR> will only
result in volume being muted, because volume command is not terminated properly.
Responses and feedback level
There are three levels of responsiveness, called feedback levels. Each level adds something new on
top of the previous level. Feedback level can be set from the control interface with command
“!VERB(X)<CR>” (X can be 0, 1 or 2). All responses start either with ‘!’ (status messages) or ‘#’ (echo
messages) and end with <CR>.
Feedback level 0: Data is only sent when data is requested by status request command. For example
command “!VOL?<CR>” would return “!VOL(XXX)<CR>”, where “XXX” would be current volume.
Feedback level 1: Data is sent whenever any of the statuses listed below changes. The data format is
the same as for responses to status request commands.
Feedback level 2: Each command is also echoed back with the ‘#’ in front of the command instead of
‘!’ character. For example command “!VOL?<CR>” would return “#VOL?<CR>!VOL(XXX)<CR>”.
