Multiple Projector Infrared Control - JVC RS-232C Remote Control Manual

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 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 too 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 7-13. 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-X30, DLA-X70, DLA-X90, DLA-RS40, DLA-RS50, DLA-
RS60, DLA-RS45, DLA-RS55 and DLA-RS65 can be set to use either hex code 73 (also
known as Code A - the code used in all of the above Infrared code examples) or hex code 63
(also known as Code B) to control them. This allows two projectors located in the same room
to be controlled independently from one Infrared source without interference between them.
There are two ways to switch the projector between Code A and Code B.
1. Use the "Infrared Remote Code" command shown on Page 4.
2. On the DLA-X3, DLA-X7, DLA-X9, DLA-RS40, DLA-RS50, and DLA-RS60, 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". On the DLA-X30, DLA-X70, DLA-X90, DLA-RS45, DLA-RS55 and DLA-RS65, this
option is in the "Function" menu.
If the projector is switched to Code B, it will then respond only to Code B (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.
It is also possible to program the Remote Control to switch between the A and B codes. To
switch between the codes, press and hold the "Menu" and "Back" buttons on the Remote
Control for three seconds or more. All of the buttons on the remote control will flash. The
buttons will flash twice to indicate that the Remote Control has switched to Code B, and three
times to indicate that the Remote Control has switched to Code A. Each time you press and
hold the "Menu" and "Back" buttons, the Remote Control will toggle between Code A and
Code B.
If you have any problems controlling the projector using the Remote Control after changing
the remote code, use the buttons on the rear of the projector to access the relevant menu, or
change the code using the "Infrared Remote Code" command shown on Page 4
