JVC D-ILA Projector Remote Control Guide

Introduction

This guide provides all of the information required to enable Remote Control of JVC D-ILA projectors, either by RS-232C connection, Infrared Remote Control, or LAN. This will enable Custom Installers or users to remotely control almost every function on these projectors.

The RS-232C control codes shown in this guide will control the JVC DLA-HD350, DLA- HD750, DLA-HD550, DLA-HD950, DLA-HD990, DLA-X3, DLA-X7, DLA-X9, DLA-RS10, DLA-RS20, DLA-RS15, DLA-RS25, DLA-RS35, DLA-RS40, DLA-RS50 and DLA-RS60 D- ILA projectors via an RS-232C connection. The commands in this guide are in raw hexadecimal format and may require conversion to work with proprietary control systems. See page 10 for some examples of how to convert them. Please note that some commands work only with specific projector models and this is indicated where applicable. If required, full details of the RS-232C interface and command format are shown on pages 15-16.

The Infrared Remote Control Codes shown in this guide will control the JVC DLA-HD350, DLA-HD750, DLA-HD550, DLA-HD950, DLA-HD990, DLA-X3, DLA-X7, DLA-X9, DLA-RS10, DLA-RS20, DLA-RS15, DLA-RS25, DLA-RS35, DLA-RS40, DLA-RS50 and DLA-RS60 D- ILA projectors via Infrared emulation. Some controllers will also generate Infrared commands from the RS-232C control codes.

The LAN Remote Control Protocol and Codes shown in this guide will control the DLA-X7, DLA-X9, DLA-RS50 and DLA-RS60 over a LAN via a TCP/IP Network Connection.

RS-232C Command Types

There are two basic types of RS-232C commands. These are:

1.Direct Commands (see page 3)

2.Remote Control Emulation Commands (see pages 4-9).

Direct Commands, as their name suggests, directly control the projector. Remote Control Emulation Commands achieve the same result, but they do it by emulating the functionality of the Remote Control Commands. The general rule is to use a Direct Command if one is available, otherwise use a Remote Control Emulation Command. One other difference between them is that Direct Commands will generally display fewer on-screen confirmation messages when the projector responds to them.

Some commands are duplicated as both a Direct Command and a Remote Control Emulation Command. For these, the Direct Command should be used in preference to the Remote Control Emulation Command unless any additional on-screen confirmation messages provided by the Remote Control Emulation Command are required. Most of the commands in the Remote Control Emulation list do not actually appear on the Remote Control Handset, but they are all available if you wish to control those functions on the projector, either by RS-232C connection, or by Infrared Remote Control.

In addition to the commands sent from the PC or controller to the projector, there are two types of Acknowledgement Response Return Codes returned by the projector to the PC or controller. When used with appropriate control equipment, these can be used to further customise the installation. Details of the Acknowledgement Response Return Codes and how to use them are on pages 11-14.

The following seven pages contain a list of all useful Direct and Remote Control Emulation Commands. Where a command is specific to an individual model or a range of models, the applicable model(s) are shown in brackets after the command name. If no model is shown, then that command works with all models.
