LYNGDORF TDAI-1120 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

he Lyngdorf Audio TDAI-1120 is compatible with home automation systems via the network
connectors on the rear socket panel and over WiFi. The TDAI-1120’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-1120 on your local network, the TDAI-1120 support Apple´s Bonjour Discovery service, which must be on the computer you want to set up the TDAI1120 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”.

The TDAI-1120 can also be controlled via the network by accessing http://TDAI-1120.local in your browser.

Control Protocol

Commands

Every command starts with ‘!’ character and ends with carriage return (ascii 0x0D, referred to in this document as ). 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 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)” (X can be 0, 1 or 2). All responses start either with ‘!’ (status messages) or ‘#’ (echo messages) and end with .
Feedback level 0: Data is sent only when data is requested by a status request command. For example, command “!VOL?” would return “!VOL(XXX)”, 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?” would return “#VOL?!VOL(XXX)”.

The following commands and requests are available on the TDAI-1120:
