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 all recent JVC 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 14 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. Full details of the RS-232C interface
and the command format are shown on pages 19-20 if required.
The Infrared Remote Control Codes shown in this guide will control all recent JVC 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-X30, DLA-X70, DLA-X90, DLA-RS50, DLA-RS60, DLA-RS45, DLA-RS55 and
DLA-RS65 over a LAN via a TCP/IP Network Connection.
RS-232C/LAN Command Types
There are two basic types of RS-232C/LAN commands. These are:
1. Direct Commands (see page 3)
2. Remote Control Emulation Commands (see pages 7-13).
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, LAN (on LAN-enabled models only), 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 15-18.
The following 11 pages contain a list of all 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. If no model is shown, then that command works with all
models.
