Multiple Projector Infrared Control

JVC D-ILA Projector Remote Control Guide

This shows both the decimal (115 and 46) as well as the hex (73 and 2E) command numbers and makes it easier to confirm that the correct command has been generated.

Using the method above, it is possible to generate any individual Pronto style Long hex command.

MakeHex can also generate a range of commands. As an example, the following entries in the .irp file would generate all commands from 22 to 45 (16 to 2D in hex).

Device=115

Function=22..45

If all of this sounds a little involved, we have produced a ready-made Long hex file. This includes all commands from 0 to 255 with both decimal and hex command numbers. This is available from:

http://uk.jvc-service.net/public/document.cfm?prog=docu.cfm&Model=DLA-HD350&SGK=0&SGT=0&MLDC_id=6918

Any required commands can be copied from this file.

Some controllers are able to create Infrared Commands from the RS-232C Remote Control Emulation Codes on pages 4-9. Where this is possible, it is a matter of personal preference as to which of them should be used.

Multiple Projector Infrared Control

The DLA-X3, DLA-X7, DLA-X9, DLA-RS40, DLA-RS50 and DLA-RS60 can be set to use either hex code 73 (as shown in all of the above Infrared code examples) or hex code 63 to control them. This allows two projectors to be controlled independently from one Infrared source. To set an individual projector to receive hex code 63 commands, go into the Service Menu, choose “Option”, and then scroll down to “IR Code” and press “OK”. In the “Code Select” option screen, move the highlighted cursor from “A” to “B” and then press “OK”. The projector will then respond only to “B” codes (hex code 63). You should then substitute the default hex code of 73 (115 in decimal) with the new hex code of 63 (99 in decimal) in all Infrared commands to control that particular projector.

When you change the projector from Code A to Code B, you will not then be able to control that projector using the normal Remote Control. To change back to Code A, use the buttons on the rear of the projector to access the Service Menu.
