Section 3: Operation
RPMX/CX50/CX60/CX67 User’s Manual 3-25
There are two methods of communicating with multiple projectors, using the IR
keypad or RS-232 serial communication. These methods are not interchangeable.
It is recommended that you choose the method which will best suit your
installation and setup your network for this type of communication.
For details on how to operate the projector using RS-232 commands, go to
www.christiedigital.com
and download the latest RS-232 communications
document for RPMX/CX50/CX60 and CX67 products.
Make sure you have assigned a unique projector ID number for each projector
present – this number is required in order to get the exclusive attention of an
individual projector with the IR keypad or by RS-232 serial communication. To
assign a projector number:
1. Press
Menu
to see the Main menu.
2. Highlight and select Communications. The Communications menu appears.
3. Scroll down to Projector ID. The two-digit number is the ID currently
assigned to the projector. To assign a new number, press
Enter
to see two
dashed lines, “- -” and enter the new two-digit ID number using the numeric
keys on the keypad.
4. Press
Enter
to accept the entry and/or
Exit
to exit the menu or cancel. See
Figure 3.25, earlier in this section.
5. Press
Status
to verify that the ID number for the projector was changed.
Continue this for each projector in your network.
When you want to communicate to all projectors in a network, press
Projector
and
ensure the option All Projectors is set to YES for each projector. (Press
Enter
to
toggle the setting, if required.) Exit the menu and verify that all projectors will
respond to a command by pressing a key, such as
Menu
on the keypad.
You can switch between communicating with all projectors and one specific
projector by pressing
Projector
and toggling the option All Projectors from YES to
NO. With All Projectors set to NO, the Projector ID option is selectable. The
number here identifies the projector that is currently listening to IR keypad
commands. All keypad commands you enter will then affect this projector
exclusively until you enter another ID number or switch back to broadcasting to
all projectors. If you want to specify another projector, highlight Projector ID
and press the
Enter
key until a double dashed line appears “--”. Using the
numerical keys on the keypad enter the 2-digit ID number of the projector you
want to communicate with. Press
Enter
to save the new ID number before exiting.
NOTE: All projectors will respond to the
Projector
key even when All Projectors is
set to NO. The number under Projector ID is not necessarily the ID of that
projector but that of the last projector you had exclusive communication with.
Press

to see the ID number assigned to a projector.
