Lyngdorf Audio TDAI-3400 – External control manual

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 TDAI-3400 is compatible with home automation systems via the RS232 and network
connectors on the rear socket panel. The TDAI-3400’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 TDAI-3400 on your local network, the TDAI-3400 supports Apple´s
Bonjour Discovery service, which must be on the computer you want to set up the TDAI-3400 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 “INFO” button on the remote and toggling through the “Info” of the unit will also display the
current IP address of the unit.
The TDAI-3400 can also be controlled via the network by accessing http://tdai-3400.local in your browser.
Control Via Serial Port
The serial port on the TDAI-3400 is wired as a DCE, so for communication with a PC or similar use a
standard straight through cable
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 TDAI-3400 via the serial port, it can wake up even when the standby mode has been
set to “deep sleep.” However, the TDAI-3400 will miss the first characters transmitted when in deep sleep,
because it needs to wake up first. To make sure the TDAI-3400 is ready for the command, send the ON-
command a couple of times in succession to 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: Feedback level 1: Data is sent whenever any status 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>”.
