In the Preferences menu, select “
Projector
". Enter a three-digit number (000 to
999) to identify the current projector. Press
to accept the entry and return to
the main menu.
Repeat for each projector, always entering a unique three-digit number. Once
every projector has its own number, you can begin to control the network.
See 2.9, Connecting to the Serial Ports for instructions on connecting projectors
together as a network.
In a serial network, make certain that only one projector — any one — has its
Broadcast Keys
option “
On
” (see Preferences menu), and that all other projectors
have their
Broadcast Keys
option “
Off
”. In addition, make sure that the keypad
you are using is enabled for this controlling projector — in the Preferences
menu, set its
Front IR
,
Rear IR
and/or
Wired Keypad
option to “
On
”. Disable the
keypad for all of the other projectors (in the Preferences menu, set
Front IR
,
Rear
IR
and/or
Wired Keypad
options to “
Off
”). The controlling projector will then
receive all remote keypad commands and relay them to the others through the
serial cables connecting the projectors.
NOTE: If you are using a wired keypad (optional) with the network, make sure
that the projector to which the keypad is connected has its
Broadcast Keys
option
set to “
On
” and the
Wired Keypad
enabled. The remaining projectors must have
their
Broadcast Keys
option off and keypads disabled.
When your network is set up, do one of the following on a remote keypad in
order to broadcast to the group:
•
Press
or
•
Press
Keypad commands will now affect all projectors. See 2.10. Keypad Protocols
and 3.7, Controlling System Parameters.
NOTES: 1) Each built-in keypad always controls its own local projector only. 2)
If you are using a computer or controller to issue commands, use the correct RS-
232 software command to broadcast.
If you want to communicate with a single projector in a network, press
to
bring up the projector number edit box. Enter the three-digit number assigned to
the projector you want to control — keypad commands will now affect only the
desired projector until you press
again and enter a different number, or
until you switch to broadcast mode (below).
NOTE: If you are using a computer or controller to issue commands, use the
correct RS-232 software command to gain control of a single projector.
Occasionally the projector may encounter an error condition that interrupts
normal operation. Such an error can be caused by an invalid user entry, an input
signal error or a system error.
