Introduction
The purpose of this document is to describe how the external control interface of the device
works.
Home Automation System Integration
The Lyngdorf Audio MP-50 is compatible with home automation systems via the RS232 and
network connectors on the rear socket panel. The MP-50’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 MP-50 on your local network, the MP-50 supports
Apple´s Bonjour Discovery service, which must be on the computer you want to set up the
MP-50 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 MP-50 can also be controlled via the network by accessing http://mp50.local in your
browser.

4Model MP-50 –External Control Manual
Control Via Serial Port
The serial port on the MP-50 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 MP-50 via the serial port, it is able to wake up even when the standby
mode has been set to “deep sleep.” However, the MP-50 will miss the first one or two
characters transmitted when in deep sleep, because it needs to wake up first. To make sure
the MP-50 is ready for the command, send a few extra characters before an ON-command.
For instance, sending “!!!POWERONMAIN” to turn on the MP-50 will guarantee that the
command is always received, even if the unit is in deep sleep.

5Model MP-50 –External Control Manual
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 formats 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 to the previous level. Feedback levels 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 sent only when data is requested by a 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 change. 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>”.

Control Protocol Usage
Controlling Power
Main zone and zone 2 power can be controlled separately with commands
!POWERONMAIN<CR>, !POWEROFFMAIN<CR>, !POWERONZONE2<CR> and
!POWEROFFZONE2<CR>.
Command !POWER?<CR> is used to get the current power status of the main zone. The
response for this command is !POWER(X)<CR>, where the X is 0 or 1, where 0 means the
main zone is off and 1 means it is on.
Command !POWERZONE2?<CR> is used to get the current power status of the main zone.
The response for this command is !POWERZONE2(X)<CR>, where the X is 0 or 1, where 0
means zone 2 is off and 1 means it is on.
Controlling Volume
Commands !VOL+<CR> and !VOL-<CR> have the same effect as pressing volume up/down
buttons from the IR remote control.
Commands !VOL+(X)<CR> and !VOL-(X)<CR> are used to increase or decrease volume by
a certain amount. The X in the commands can be anything between 1 and 999 (0.1dB –
99.9dB).
Command !VOL(X)<CR> is used to set the volume to some specific value. The X in the
command can be -999 –200 (-99.9dB –20.0dB).
Commands !MUTEON<CR>, !MUTEOFF<CR> and !MUTE<CR> are used to set mute, clear
mute, and toggle mute, respectively.
Command !VOL?<CR> is used to get the current value of the main zone volume. The
response for this command is !VOL(X)<CR>, where X can be -999 –200 (-99.9dB –
20.0dB). Please note that if verbosity level 1 or higher is used, volume information will be
updated to the control interface automatically. There is always at least a 100ms time period
between the volume status messages. This period is used to prevent flooding the control
interface with too frequent volume updates every time the volume is being adjusted.
Commands !ZVOL+<CR>, !ZVOL-<CR>, !ZVOL+(X)<CR>, !ZVOL-(X)<CR>,
!ZVOL(X)<CR>, !ZVOL?<CR>, !ZMUTEON<CR>, !ZMUTEOFF<CR> and !ZMUTE<CR> are
used to control zone 2 volume the same way as the main zone volume.

14 Model MP-50 –External Control Manual
Please note that the volume value in control protocol commands is always in 0.1dB
accuracy, meaning that 1.0dB is a value of 10 in the control protocol. This is true for volume
status messages and volume control commands.
Warning: Usage of a maximum volume setting is highly recommended to prevent damage to
equipment because of an excessive volume setting! It is never possible to set the volume
above the maximum volume level setting with control interface commands, but it is very easy
to accidentally reach the maximum volume level.

15 Model MP-50 –External Control Manual
Controlling Sources
Main zone:
A source is a combination of video inputs and audio inputs that can be selected freely from
the user interface. The number and names of sources can vary depending on how many
sources have been created when setting up the system. The installer can add, delete, edit,
and re-order the sources at any time.
Command !SRCS?<CR> is used to find out how many sources there are and what they are
named. For example, a response for !SRCS<CR> could be:
!SRCCOUNT(4)<CR>
!SRC(0)"DVD player"<CR>
!SRC(1)"Blu-ray player"<CR>
!SRC(2)"Game console"<CR>
!SRC(3)"PVR"<CR>
It can be seen from the response that there are 4 sources, named “DVD player,” “Blu-ray
player,” “Game console,” and “PVR.”
Command !SRC?<CR> is used to find out which source is currently selected. The response
for this command is !SRC(X)”NAME”<CR> where X is the index of the currently selected
source (0 is the first index) and NAME is the name of the currently selected source.
Commands !SRC+<CR> and !SRC-<CR> are used to select next or previous source.
Command !SRC(X)<CR> is used to select a specific source. The X in the command can be
anything between 0 and the index of the last source. This response is also sent
automatically, when the source changes, if feedback level is 1 or higher. If main zone is off,
the MP-50 will reply with the previous selected source.
Zone 2:
Sources on zone 2 are a subset of the sources set up for main zone. Command
!ZSRCS?<CR> is used to find out the indexes and names of the zone sources. For example,
a response for !ZSRCS?<CR> could be:
!ZSRCCOUNT(5)
!ZSRC(0)"Follow Main"<CR>
!ZSRC(1)"CD player"<CR>
!ZSRC(2)"SACD player"<CR>
!ZSRC(3)"MP3 player"<CR>
!ZSRC(4)"TV Sound"<CR>
It can be seen from the response that there are 5 zone 2 sources named “Follow Main,” “CD
player.” “SACD player,” “MP3 player,” and “TV Sound.” “Follow Main” is a special source,

16 Model MP-50 –External Control Manual
which is always present. It will send the sound from whichever source is selected in the main
zone to zone 2.
Command !ZSRC?<CR> is used to find out which zone 2 source is currently selected. The
response for this command is !ZSRC(X)”NAME”<CR> where X is the index of the currently
selected source (0 is the first index) and NAME is the name of the currently selected source.
This response is also sent automatically, when the zone 2 source changes, if feedback level
is 1 or higher. If zone 2 is turned off, the MP-50 will reply with the previous selected source.
Commands !ZSRC+<CR> and !ZSRC-<CR> are used to select next or previous source.
Command !ZSRC(X)<CR> is used to select a specific source. The X in the command can be
anything between 0 and the index of the last source.

17 Model MP-50 –External Control Manual
Controlling Processing Modes
The MP-50 processor has controls for selecting processing modes, also called audio modes.
Command !AUDMODEL?<CR> can be used to get a list of processing modes; how many
are there and what they are named. For example, a response for command
!AUDMODEL?<CR> could be:
!AUDMODECOUNT(8)
!AUDMODE(0)"None"<CR>
!AUDMODE(1)"dts Neo:X Cinema"<CR>
!AUDMODE(2)"dts Neo:X Music"<CR>
!AUDMODE(3)"dts Neo:X Game"<CR>
!AUDMODE(4)"Auro-3D/Auromatic"<CR>
!AUDMODE(5)"Dolby Upmixer"<CR>
!AUDMODE(6)"Stereo"<CR>
!AUDMODE(7)"Party"<CR>
Commands !AUDMODE+<CR> and !AUDMODE-<CR> are used to select next and previous
audio mode from the list of available audio modes.
Command !AUDMODE(X)<CR> is used to select a specific processing mode, where X is an
audio mode index as seen in the reply above.
Command !AUDMODE?<CR> is used to find out which processing mode is currently
selected. The response for this command is !AUDMODE(X)”Name”<CR>, where X is the
index of the audio mode and Name is the name of the audio mode. This response is sent
automatically, when the audio mode changes, if feedback level is 1 or higher.

18 Model MP-50 –External Control Manual
Controlling Focus Positions
Command !RPFOCS?<CR> is used to get the list of selectable focus positions along with
their names. For example, a response for !RPFOCS<CR> could be:
!RPFOCCOUNT(4) <CR>
!RPFOC(1)"Focus 1"<CR>
!RPFOC(2)"Focus 2"<CR>
!RPFOC(4)"Focus 4"<CR>
!RPFOC(9)"Global"<CR>
It can be seen from the response that there are 4 RoomPerfect positions, named “Focus 1,”
“Focus 2,” “Focus 4,” and “Global.” Note that the numbering of the positions is not
consecutive.
Command !RPFOC?<CR> is used to find out which position is currently selected. The
response for this command is !RPFOC(X)”NAME”<CR> where X is the index of the currently
selected position (a value between 0 and 9) and NAME is the name of the currently selected
position. This response is sent automatically whenever the position is changed if feedback
level is 1 or higher.
Commands !RPFOC+<CR> and !RPFOC-<CR> are used to select next or previous position.
Command !RPFOC(X)<CR> is used to select a specific position. The X in the command can
be any index from the list of measured focus positions retrieved by using command
!RPFOCS?<CR>.
The installer might add or remove focus positions at any time, so it is recommended to
update the list of selectable focus positions at least in every boot-up.

19 Model MP-50 –External Control Manual
Controlling Voicings
Command !RPVOIS?<CR> is used to find out the list of selectable voicings along with their
names. For example, a response for !RPVOIS<CR> is:
!RPVOICOUNT(7)<CR>
!RPVOI(0)"Neutral"<CR>
!RPVOI(1)"Music"<CR>
!RPVOI(2)"Music II"<CR>
!RPVOI(3)"Relaxed"<CR>
!RPVOI(4)"Tilt"<CR>
!RPVOI(5)"Action"<CR>
!RPVOI(6)"Action+Movie"<CR>
It can be seen from the response that there are 7 voicings, named “Neutral,” “Music,” “Music
II,” “Relaxed,” “Tilt,” “Action,” and “Action+Movie.”
Command !RPVOI?<CR> is used to find out which voicing is currently selected. The
response for this command is !RPVOI(X)”NAME”<CR> where X is the index of the currently
selected voicing (0 is the first index) and NAME is the name of the currently selected voicing.
This response is sent automatically whenever the current voicing is changed if feedback
level is 1 or higher.
Commands !RPVOI+<CR> and !RPVOI-<CR> are used to select next or previous voicing.
Command !RPVOI(X)<CR> is used to select a specific source. The X in the command can
be any index from the list of voicings.
Controlling Lipsync
Command !LIPSYNC?<CR> is used to find out the current value of the lipsync trim. The
response for this command is !LIPSYNC(X)<CR> where X is the current lipsync trim in
milliseconds.
Commands !LIPSYNC+<CR> and !LIPSYNC-<CR> are used to adjust the lipsync trim value
by 5ms or -5ms, respectively. Command !LIPSYNC(X)<CR> is used to set the lipsync trim
directly. The valid value range for this command needs to be fetched from the MP-50 (see
below).
Please note that the valid range to adjust the lipsync delay is retrieved with
the!LIPSYNCRANGE? command, returning minimum and maximum value in ms.
Getting main zone video and audio status

20 Model MP-50 –External Control Manual
It is possible to find out the currently selected source’s video and audio input and current
video and audio format in main zone.
Command !VIDIN?<CR> is used to find out the used video input of the currently selected
source. The response for this command is !VIDIN(X)<CR>, where X is the current video.
See table of video inputs for the translation of the number to actual video input. This
response is sent automatically whenever input selection changes if feedback level is 1 or
higher.
Command !AUDIN?<CR> is used to find out the used audio input of the currently selected
source. The response for this command is !AUDIN(X)<CR>, where X is the current audio
input. See table of audio inputs for the translation of the number to actual audio input. This
response is sent automatically whenever input selection changes if feedback level is 1 or
higher.
Command !VIDTYPE?<CR> is used to find out the current video input format. The response
for this command is !VIDTYPE(Typestring)<CR>, where Typestring is a string describing the
current video format. This response is sent automatically whenever input signal changes if
feedback level is 1 or higher.
Command !AUDTYPE?<CR> is used to get information about the current audio signal type.
The response for that command is !AUDTYPE(Typestring)<CR>, where Typestring is a
string describing the current input audio type. This response is sent automatically whenever
input signal changes if feedback level is 1 or higher.
Getting Zone 2 Audio Status
It is possible to request the currently selected zone source’s audio input in zone 2.
Command !ZAUDIN?<CR> is used to find out the used audio input of the currently selected
zone source. The response for this command is !ZAUDIN(X)<CR>, where X is the current
zone 2 audio input. See table of audio inputs for the translation of the number to actual audio
input. This response is sent automatically whenever input selection changes if feedback
level is 1 or higher.
Controlling Feedback Level
It is possible to set the feedback level from the external control interface with command
!VERB(X)<CR>, where X is the wanted feedback level 0, 1 or 2.
