7. LW3 Programmers’ Reference

MMX6x2-HT series – User's Manual

LW3 Programmers’ Reference

The device can be controlled through Lightware 3 (LW3) protocol commands

to ensure the compatibility with other Lightware products. The supported LW3

commands are described in this chapter.

7.1.

Overview

The Lightware Protocol #3 (LW3) is implemented in almost all new Lightware devices (matrix switchers,

signal extenders and distribution amplifiers) since 2012. The protocol is ASCII-based and all commands

are terminated with a carriage return (Cr, ‘\r’) and line feed (Lf, ‘\n’) pair. It is organized as a tree structure

that provides outstanding flexibility and user-friendly handling with ‘nodes’, ‘properties’ and ‘methods’. The

Advanced View

of the Lightware Device Controller software is the perfect tool for browsing and learning how

the LW3 protocol can be used in practice.

7.2.

Protocol Rules

7.2.1. LW3 Tree Structure and Command Structure (Examples)

7.2.2.

General Rules

▪

All names and parameters are

case-sensitive

▪

The nodes are separated by a slash (‘/’) character.

▪

The node names are comprised of the elements of the English alphabet and numbers.

▪

Use the

TCP

port no. 6107

when using LW3 protocol over Ethernet.

▪

Node paths describe the exact location of the node, listing each parent node up to the root.
