DLV 1280 User's Manual
The wired remote keypad connects to the DLV 1280 remote jack via a 25 ft
extension cable. This keypad is particularly useful when:
•
the location of the keypad in relation to the projector or screen is inadequate
for IR Remote Keypad operation.
•
the lighting conditions are unsuitable for proper IR transmission
•
you are controlling multiple projectors in the same room and need to control
each by its own remote keypad.
NOTE: The wired keypad layout and functions are identical to the IR remote.
The following guidelines apply for all DLV 1280 keypads.
1)
Press and release keys one at a time.
2)
You must hold down
for about a second in order to turn the projector
on or off. For other keys, a momentary press similar to a mouse click is
sufficient.
3)
Any key press temporarily illuminates the backlight for reading the keys
(applies to remote keypads only).
4)
, , , , and usually repeat their actions when held down. For
other keys, release and press again to repeat an action.
5)
Any number key will function as a number within all parts of the menu
system.
6)
If you press a key while the projector is busy with another action, such as
during power-up, the key press may not take effect.
When you turn on the projector it begins operating at presentation level, which
displays the image from the existing source signal. The projector temporarily
leaves presentation level when you use the keypad to change control settings,
display menus, or access on-line help. For example, pressing
after startup
displays the main menu list for access to specific functions — presentation level
remains visible but is no longer considered “active”. Pressing
again (or
) returns to presentation level.
Keypad operating settings (protocols)
The remote keypad and the optional wired keypad both can store keypad
operating settings (also called protocols) in memory. In some advanced
applications, such as when you want to use two separate keypads to control two
projectors independently, you may want to override the original protocol (called
Protocol "A") set during manufacture. See 2.10, Keypad Protocols for complete
instructions on changing protocol.
Basic keypad commands are explained below.
Power ON / OFF
Press
and hold for approximately one second to turn the projector on or
off.
NOTES: 1) Once the projector is turned off, fans remain on for about five
minutes to cool the lamp as quickly as possible. 2) Always avoid turning the
Wired Remote Keypad
