JVC D-ILA Projector Remote Control Guide
Page 2 of 14
Introduction
This guide is intended to provide all of the information required to enable Remote Control of
JVC D-ILA projectors, either by RS-232C connection or by Infrared Remote Control. This will
enable Custom Installers or users to remotely control almost every function on these
projectors.
The RS-232C codes shown in this guide will control the JVC DLA-HD350, DLA-HD750, DLA-
HD550, DLA-HD950, DLA-HD990, DLA-RS10, DLA-RS20, DLA-RS15, DLA-RS25 and DLA-
RS35 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 7 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. Although the
majority of users and installers will probably not require it, full details of the RS-232C
interface and command format are shown on pages 12-13.
The Infrared Remote Control Codes shown in this guide will control the JVC DLA-HD350,
DLA-HD750, DLA-HD550, DLA-HD950, DLA-HD990, DLA-RS10, DLA-RS20, DLA-RS15,
DLA-RS25 and DLA-RS35 D-ILA projectors via Infrared emulation. Some controllers will also
generate Infrared commands from the RS-232C control codes.
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 4-6).
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 extra on-screen confirmation messages
provided by the Remote Control Emulation Command are required. Many 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 8-11.
The following four pages contain a list of all useful Direct and Remote Control Emulation
Commands.
