Broadcast Key
Enter a checkmark if you want keypad commands sent to any one projector to be
relayed to all projectors in a serial network. Note that the
Proj
key will temporarily
“override” the effect of a broadcast setting and allow you to control a specific
projector when necessary. Make sure to remove the Broadcast Key checkmark when
operating redundant networks.
Backlight
Toggle the built-in keypad lighting on/off.
Front IR / Back IR
As needed for your application, set to “on” so that the front and/or rear IR sensor
locations on the projector responds to the IR keypad. Set to “off” to disable.
To disable both IR sensors, you cannot use the IR remote keypad to select the second
OFF
setting. This safeguard prevents accidentally disabling an IR keypad while you
are using it. Instead, use either the built-in keypad or a wired remote (optional) to set
the remaining active sensor to
OFF
. The projector will no longer respond to an IR
remote keypad.
Wired Keypad
Select “On” to enable use of a wired remote keypad connected to the rear of the
projector. The projector will then respond to incoming commands from either port. To
disable the wired keypad, you must use a different keypad—the built-in or an IR
remote keypad—to select “off”. This safeguard prevents you from accidentally
disabling the wired keypad during use.
In the Configuration menu, select
the Geometry and Color submenu
when you need to modify overall
color performance and/or image
geometry for all sources.
Test Pattern
Choose the desired internal test pattern or select OFF to turn off a test pattern.
Alternatively, use the
Test
key for cycling through test patterns.
Vertical Keystone
Use to correct a keystoned image shape in which both sides of your image are inclined
toward the top or bottom edge. Keystone is typically caused by tilting the projector in
relation to the screen, so that the lens surface and screen are no longer parallel to each
other.
