JVC D-ILA Projector Remote Control Guide  
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:  
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:  
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.  
Another more advanced program. This one is particularly good for checking the  
Acknowledgement Response Return Codes.  
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:  
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 null-  
modem or DTE/DTE cable) if you wish to connect the projector to a PC for testing.

Acknowledgement Response Return Codes - Basic  
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  
06 89 01 50 57 0A  
06 89 01 49 50 0A  
06 89 01 54 53 0A  
06 89 01 47 54 0A  
06 89 01 47 50 0A  
06 89 01 52 43 0A  
06 89 01 00 00 0A

Gamma Table Changed

Remote Control Emulation Command (all commands)  
Test (Null Command – to check communication)  
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.

JVC D-ILA Projector Remote Control Guide  
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:

JVC D-ILA Projector Remote Control Guide  
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  
Header  
Unit ID  
Command  
Data  
Size  
1 byte  
2 bytes  
2 bytes  
Variable  
1 byte.  
Comments  
Can be one of four possible values – see below  
Fixed – always 89 01  
See below  
Length varies depending on command – see below  
Fixed – always 0A  
End  
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).

JVC D-ILA Projector Remote Control Guide  
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.
