built-in keypad at the rear of the projection head remote keypad for tethered or tetherless control (includes cable for connecting as a wired remote)
while each of the keypads provides complete control of the projector, they differ slightly in their arrangement of keys and in which functions can be accessed directly with a key press rather than requiring use of the menu system. you may find one keypad more convenient than another for your specific installation and application.
built-in
to control the projector when signals from a remote keypad cannot reach the projector, use the projector’s built-in keypad(figure 3.2) . two nearby status windows provide feedback indicating current status and activities of the projector. because the built-in keypad has fewer keys than the remote keypad, certain projector functions are accessible only through the menu system rather than via a direct key.
ir remote
the ir remote keypad controls the projector by way of wireless communications from a battery-powered infrared (ir) transmitter. use the ir remote keypad the same way you would use a remote keypad supplied with a tv or vcr. when making key presses, direct the keypad either toward the screen or toward the front or rear of the projector. one of the two ir sensors on the projector will detect the signals and relay the commands for internal processing. refer to the key descriptions provided for the ir remote (figure 3.3).
wired remote
with the addition of a cable (supplied) and the selection on the menu of the wired remote function, the ir remote converts into a wired remote keypad. this wired keypad connects to the remote input at the rear of the projector by the provided cable. the wired remote is recommended when:
the rear built-in keypad is inaccessible
the lighting conditions are unsuitable for proper ir transmission
enable the “wired keypad” checkbox in the communications menu.
leave the batteries in the wired remote for the laser key to work.
guide to keypads
1) press keys one-at-a-time; there are no simultaneous key combinations required.
2) note that three keys—power, shutter and osd—are “press-and-hold” keys that do not function with a typical quick press-and-release keypress.
3) hold arrow keys down for continuous adjustment/movement in one direction. in serial networks, pause briefly between adjustments to ensure that more distant projectors can “keep up” with the commands.
4) if you press a key while the projector is still responding to the previous action, such as during power-up, the second key press may not take effect.
keypad commands
specific keypad commands are explained below:
1) after powering down, the lamp cooling fan remains on for approximately 5 minutes to cool the lamp. 2) it is a good idea to avoid turning a projector back on until it has been off for a few minutes. hot re-strikes of the lamp may reduce lamp life.
you must have an unlocked channel present to use auto setup.
channel
channel (channel) key behavior during a presentation depends on whether or not the display channel list option is enabled in the menu preferences menu. you can choose to use a scrollable list of channels when you press channel , or you may prefer to enter the desired channel number “blind”, i.e., without on-screen feedback. see menu preferences later in this section.
input 1
press input 1 to display from the data input source connected to bncs labeled input 1.
input 2
press input 2 to display from the dvi source connected to input 2.
input 3
press input 3 to display from the composite video source connected to input 3.
input 4
press input 4 to display from the s-video source connected to input 4.
input 5
press input 5 to display from the input 5 interface module installed in the option 1 slot, which is typically the standard factory-installed dual sd/hd-sdi module. note that if there are two inputs connected here, the second input (b) is considered input 7. if you are using the built-in keypad or the remote keypad, press input 5 to access input 7 as follows:
while displaying from input 5, press input 5 again. this switches to input 7.
while displaying from any input other than the dual sd/hd-sdi module, press input 5 . this switches to either input 5 or input 7, depending on which of the dual sd/hd-sdi module inputs (a or b) was last used. press input 5 again to display from the other dual sd/hd-sdi module input.
input 6
this key is not available on the built-in keypad and has no function when pressed on the remote.
contrast
brightness
gamma
“gamma” determines what gray shades are displayed between minimum input (black) and maximum input (white) for a given amount of signal. the proper setting helps maintain optimized blacks and whites while ensuring a smooth transition for the “in-between” values utilized in colors and grays. thus, unlike brightness and contrast settings controls, the overall tone of an image can be lightened or darkened without changing the two extremes, and your images will be more vibrant yet with good detail in dark areas.
the normal gamma setting of 2.2 is correct for most signals and conditions. if excess ambient light washes out the image and it becomes difficult or impossible to see details in dark areas, lower the gamma setting to compensate. this will improve contrast ratio while maintaining good details for blacks.
menu
press menu to enter or exit the projector’s menu system.
osd (on-screen display)
invisible menus are fully functional, enabling “hidden” access to numbered features and image adjustments by entering the corresponding sequence of keypresses on the keypad.
1) with osd “on”, you can still hide error messages and slidebars by disabling these options in the menu preferences menu. 2) the state of the on-screen display appears in the lcd window at the rear of the projector.
shutter
1) the status of the shutter is shown in the lcd display window at the rear of the projector. 2) the shutter is open upon power-up.
function key
if within a menu: using the func for special tasks within the menu system is noted with the appropriate topic elsewhere in section 3. for example, press func in the channel setup menu to enable deletion or copying of a channel.
if within a presentation: press func followed by a 2-digit number to enable a specific color or colors in the display (see right). for example, 6 4 func will display only red and green data, 6 7 func will display all color data. eliminating one or more colors can help with certain diagnostics and setups, such as when accurately overlaying one image on top of another from stacked projectors.
color enabling can also be implemented from numerous locations within the menu system.
projector
press proj to access a specific projector within a group of projectors or to confirm if the local projector is listening. the number in the “enter number” window indicates which projector is currently listening to commands, and will match the projector number that has been defined in the menu preferences menu.
the “projector” checkbox (read-only) shows whether or not the projector physically connected to a keypad is listening to commands from that keypad. a checkmark means that connected projector is listening; if there is no checkmark, you are communicating with a different projector.
to control a specific projector with the keypad, enter the 3-digit number assigned to the projector you want to use. if you switch to a projector other than the one you are currently using, the checkmark will disappear.
to broadcast to multiple projectors, press proj and then proj again without entering a projector number. keypad commands will then affect all projectors present. note that there is no method of controlling a group of projectors within the same wired configuration using the wired keypad exclusively, since there is only one wired protocol available.
1) the "broadcast keys" option in the communications menu must be selected for only one (any) projector in a serial network. the keypad in use must be off (disabled) for the remaining projectors. see also 2.14 remote keypad protocols and conversion, and 3.6, adjusting system parameters and advanced controls.
enter
exit
press exit to return to the previous level, such as the previous menu.
exit does not save changes within text editing boxes (including number editing of a slidebar value) or within pull-down lists. it acts as a “cancel” in these cases.
