JVC D-ILA Projector Remote Control Guide

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, DLA­HD550, DLA-HD950, DLA-HD990, DLA-RS10, DLA-RS20, DLA-RS15, DLA-RS25 and DLA­RS35 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 RS­232C 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.

Converting & Testing Codes

The codes shown on pages 3-6 are raw hex codes and must be converted to the appropriate
format in order to work with proprietary controllers such as those from Crestron or AMX. To
help with the conversion, here are two sample strings for those brands:

Crestron controller – Power On Command:
\x21\x89\x01\x50\x57\x31\x0A\r

AMX controller – Power On Command:
SEND_STRING dvProj, "$21, $89, $01, $50, $57, $31, $0A”

You can see from these examples that it is easy to convert any of the RS-232C codes in this
guide into the equivalent Crestron or AMX control strings. This should also be the case for
most other controllers that allow transmission of hex data.

In order to test these commands, it is useful to have a program that can send raw hex codes
directly to the Serial port on a PC. There are many programs that can do this, but there are a
few that are useful for test purposes:

RS232 Hex Com Tool – 30 Day Evaluation Version available from http://www.rs232pro.com

This is a very simple to use program that lets you send any hex command and see the
response from the projector. The Evaluation Version times out every five minutes, but it can
be instantly restarted and is very simple to use.

Hercules Setup Utility – Free from:
http://www.hw-group.com/products/hercules/index_en.html

This is a slightly more complex program that can do far more than just send hex commands.
Use the “Serial” tab to send commands direct to the serial port. This program is
recommended if you are a more experienced PC user.

Docklight – Evaluation version available from: http://www.docklight.de

Another more advanced program. This one is particularly good for checking the
Acknowledgement Response Return Codes.

AccessPort – Free from: http://www.sudt.com/en/ap/index.html

This is an intermediate level program. Not as easy to use as some of the others, but free.

Eltima Software Advanced Serial Port Terminal – 14 Day Evaluation Version available from:
http://www.eltima.com/products/serial-port-terminal/

This is an excellent intermediate level program. It allows the commands to be sent in loops
for repeated testing. It also shows the return codes in both hex and ASCII formats.

If you want to use just one program from those above for general testing, I would recommend
the Hercules Setup Utility.

All of these programs will accept the hex codes exactly as shown in this guide. They can
simply be copied and pasted into the programs and then sent to the projector. Most of the
programs require the user to switch to hex mode before sending hex codes.

Please note that you will require a cross-connected serial cable (sometimes called a null­modem or DTE/DTE cable) if you wish to connect the projector to a PC for testing.

In most installations, it will normally be sufficient just to send a command to the projector and
assume that the projector will carry it out requested. In some installations, there may be a
requirement to confirm that the projector has carried out the command before continuing.
This is particularly important when sending multiple commands. It is possible to check if the
projector has carried out a command by monitoring the Acknowledgement Response Return
Code returned by the projector. The projector will return an Acknowledgement Response
Return Code for any valid command that it receives.

The general format of the Acknowledgement Response returned from the projector is:
06 89 01 CC CC 0A - Where CC CC is the first 2 bytes of the command that was originally

sent to the projector (not including the 21 89 01).
Taking the Power On command from page 3 as an example, to switch the projector power

on, we would send to the projector:
21 89 01 50 57 31 0A
If the Power On Command completes successfully, the projector will return:
06 89 01 50 57 0A
This Acknowledgement Response format is the same for all of the commands listed above.
The Acknowledgement Response Return Codes for all of the commands listed on pages 3-6

(assuming the command is successful) are as follows:

Function Acknowledgement Response

Power On/Off 06 89 01 50 57 0A
Input Changed 06 89 01 49 50 0A
Test Pattern On/Off 06 89 01 54 53 0A
Gamma Table Changed 06 89 01 47 54 0A
Gamma Value Changed 06 89 01 47 50 0A
Remote Control Emulation Command (all commands) 06 89 01 52 43 0A
Test (Null Command – to check communication) 06 89 01 00 00 0A

The list above includes a Test (null) response. This doesn’t actually do anything, but it is
useful to check that the controller is communicating with the projector before sending any
real commands. This should be used with the Test Command shown on page 3.

If we send to the projector:
21 89 01 00 00 0A
Assuming the projector is connected to the PC or controller correctly, it will respond with:
06 89 01 00 00 0A
It will respond whether it is in Standby or Powered On.

Acknowledgement Response Return Codes - Advanced

For some functions, it is possible to obtain a more detailed response from the projector. This
is useful where different actions are required depending on the current projector settings or
status. To request the detailed response, taking the above example of the Power Command,
we would send to the projector:

3F 89 01 50 57 0A
If the projector receives the enquiry command, as a confirmation that it has received the

command, it will first respond with exactly the same information as that returned by the basic
Acknowledgement Return Code shown on page 8:

06 89 01 50 57 0A
Next, the projector will send the detailed response. It will send:
40 89 01 50 57 RR 0A – Where RR is the Detailed Response Return Code.
For clarity, the two returned responses are separated here. In practice, they are returned

from the projector as one continuous string.
For the power Status Enquiry, the possible values for the Detailed Response Return Code

status (RR) are:
30 – Standby

31 – Power On
32 – Cooling
34 – Emergency

So, as a full worked example, if we send to the projector:
3F 89 01 50 57 0A
If the projector were currently cooling down after being switched to Standby, it would return:
06 89 01 50 57 0A 40 89 01 50 57 32 0A
If the projector were on Standby, it would return:
06 89 01 50 57 0A 40 89 01 50 57 30 0A
A list of all of the useful enquiry codes, together with all possible detailed responses is below:

There is one enquiry command that has a different response from the projector to those
listed above. This is the Model Status enquiry. When this enquiry sent to the projector, the
projector will respond with a 14-byte string that identifies the model number(s) of the
projector.

Details are as follows:

Command Format

The RS-232C commands are bidirectional and consist of a variable number of hexadecimal
numbers. All of the commands sent to the projector shown in this guide are either 7 bytes or
10 bytes long. The Acknowledgement Response Return Codes returned from the projector
can be between 6 and 14 bytes long. The basic format of the commands is as follows:

Section Size Comments

Header 1 byte Can be one of four possible values – see below
Unit ID 2 bytes Fixed – always 89 01
Command 2 bytes See below
Data Variable Length varies depending on command – see below
End 1 byte. Fixed – always 0A

Taking each of these sections in turn:

Header

The header can be one of 4 possible values. These are:
21 – Operating Command (from PC/controller to projector)
3F – Acknowledgement Response return Code Request (from PC/controller to projector)
06 – Acknowledgement Response Return Code – Basic (from projector to PC/controller)
40 – Acknowledgement Response Return Code – Detailed (from projector to PC/controller)

Unit ID

This is fixed at 89 01 for all models.

Command

This is the command sent to/from the projector and varies depending on the command. As
an example, the Power Command is 50 57. The other commands can be worked out from
the tables on pages 3-6.

Data

This is the value to apply to the command. Using the Power example above, the data value
for Off is 30 and the data value for On is 31.

End

This signifies the end of the command and is fixed at 0A for all models.
Putting all this together, a typical command (Power On) to the projector would therefore be:

21 89 01 50 57 31 0A

Header Unit ID Command Data End

Error Handling

The projector will ignore any commands that it cannot recognise, e.g. Unit ID does not
match, parity error, invalid command, etc. It will also ignore any inappropriate commands,
e.g. Power On when in cooling mode.

The projector will discard any commands received if there is a break of 50ms or longer in the
incoming data.

If consecutive commands are used, it is assumed that any external controller will not transmit
a command until it has received an appropriate Acknowledgement Response Return Code to
confirm that the projector is ready to accept the next command (see page 8 for details).

Infrared Control

It is also possible to control JVC D-ILA projectors via Infrared Remote Control Signal
Emulation, though is this sometimes slightly more difficult to achieve than RS-232C control
due to the differences in Infrared emulation methods between the various equipment
manufacturers.

To send an Infrared command to the projector, the required format is 73, followed by the
ASCII value in hex of the command required. The ASCII values for all of the Remote Control
Emulation Commands are shown in right hand column of the Remote Control Emulation
Command tables on pages 4-6.

As an example, to send the Power On command, we would send: 73 05
It is unlikely that these raw commands will work with proprietary Infrared controllers and they

will have to be converted to the appropriate format before use. For the most common
Infrared control system, the Philips Pronto, the widely available free “MakeHex” program
should be able to convert the codes from this document into the “Long hex” format used by
Pronto and other similar systems. Full details of how to carry out the conversion are included
with the MakeHex program. When using MakeHex, you should set “Device=73” in the
MakeHex .irp input file.

Some controllers are able to create Infrared Commands from the hex Remote Control
Emulation Codes on pages 4-6. Where this is possible, it is a matter of personal preference
as to which of them should be used.
