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.

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.

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>”.
