INTRODUCTION

This Installation Manual was created to assist with installation and use of the Steinway Lyngdorf

device control interface for Model D and C music systems.

For assistance with Steinway Lyngdorf speakers or electronics or with RoomPerfect™, please see

associated installation manuals. Please read all material carefully prior to installation. If you need

additional assistance, contact your Steinway Lyngdorf representative or email

service@steinwaylyngdorf.com.

COMPLIANCE

WEEE

The European Parliament and the Council of the European Union have issued the Waste Electrical

and Electronic Equipment Directive. The purpose of the Directive is to prevent waste of electrical and

electronic equipment and to promote reuse, recycling, and other forms of waste recovery. Steinway

Lyngdorf products and the accessories packed with them are subject to the WEEE Directive. Please

dispose of any waste materials in accordance with your local recycling regulations. Products and

equipment which must be collected for reuse, recycling, and other forms of recovery are marked with

the icon of the crossed-out waste receptacle.

FCC

Steinway Lyngdorf products and accessories comply with parts 15 and 68 of the FCC rules. Operation

is subject to the following two conditions: (1) this device may not cause harmful interference; and (2)

this device must accept any interference received, including any interference that may cause

undesired operation. Changes or modifications not expressly approved by the party responsible for

compliance could void the user’s authority to operate the equipment. Equipment marketed to a

consumer must be capable of complying with the necessary regulations in the configuration in which

the equipment is marketed.

SERIAL INTERFACE

This document describes the interface to control a Steinway Lyngdorf system through an MCB-1 and

RF interface box. The interface between PC and interface box is UART based.

This section briefly describes a standard UART based communication protocol to be used in the

interface. The protocol is a peer-to-peer communication for basic control of a Steinway Lyngdorf

system.

Layer 1

Layer 1 communication is standard asynchronous serial communication 8N1 at a speed that may vary

depending on the project.

For the Crestron RF interface a speed of 38400 has been chosen.

For the MCB-1 interface a speed of 115200 has been chosen.

Layer 2

Layer 2 handles framing of telegrams using a 1 byte counter

Counter

Payload

The counter contains the size of the payload (without the counter itself!).

Layer 3-7

The only functionality on the higher layers is a switch to send the telegram to the appropriate part of

the software. For this purpose, the first byte of the payload is treated as an object-byte. The rest of the

payload is treated differently depending on the value of the object-byte.

TELEGRAMS

This section describes the structure of the payload of the telegrams.

Payload

The first BYTE in the payload is the object, and dependent on the value of this, the rest of the

telegram is structured.

The Device type for this interface is a constant value defined as:

Device type:DEVICE_TYPE_HEAD_UNIT = 0x00

Reply telegrams follow the same structure, except that the first parameter of each reply telegram

contains a STATUS which tells whether the telegram was processed correctly. A value of 0x00 means

success.
