INSTALLATION AND SETUP
Projector Numbers
Each projector can be assigned a unique 3-digit projector number (for example, 001). These num-
bers are particularly useful when you are working with multiple linked projectors, enabling you
to direct commands to a certain projector rather than always broadcasting to the entire network.
For complete information on how to assign projector numbers, see3.7, Adjusting System
Parameters and Advanced Controls.
NOTE: To loop a single incoming video source through to another projector or display device on
a network, see Video Loop Throughin 2.4, Source Connections.
2.10 Keypad Protocols and Conversion
At manufacture every keypad is assigned “A” as its default protocol, which is simply a collection
of settings that determine how the keypad operates. Once assigned, this protocol remains in effect
until it is changed-that is, the keypad will operate as it currently does until you change its proto-
col.
Protocols are most useful for multiple-projector applications. For example, you might want to
change a keypad protocol if you are working with two projectors and two remote keypads in the
same room and need to control each projector independently (Figure 2.24). When Keypad A has
a different protocol than Keypad B, each keypad communicates only with the projector having a
matching protocol. Or, if you have a network of two or more projectors connected together via
RS-232 serial ports, you may want only certain projectors to respond to a wired keypad, thus you
can use different protocols to limit responses.
NOTE: Matching the protocol on the projector to that of a keypad is done through a setting in the
Communicationsmenu. See 3.7, Adjusting System Parameters and Advanced Controlsfor fur-
ther information on how to change the projector’s infrared sensor (rear and front) protocol.
A protocol for either type of remote keypad - IR or wired - can be changed through software com-
mands entered on the keypad. A new protocol set through software commands remains in effect
until the keypad batteries are removed and replaced (if an IR remote), or until the keypad is
unplugged (if a wired remote). A remote can also be changed manually -you can “hard-wire” new
jumper settings inside the keypad so that they remain in effect until you change the hard-wiring.
Note that a hard-wired protocol can be temporarily overridden by the software protocol change,
effective until the keypad is unplugged and plugged in again (if a wired remote) or until a battery
is removed (if an IR remote).

INSTALLATION AND SETUP
Figure 2.24. Independent Keypads and Projectors
Remote KeypadProtocol  - IR OR WIRED KEYPAD -
The standard IR remote keypad or the optional wired remote can be set to one of two 
different protocols -  “A” or “B”. To hard-wire a protocol to “A” or “B” in either remote, 
follow Steps 1 through 5: 
Step 1
Unplug the keypad from the projector (applies to wired remote only). 
Step 2
Unlatch and open the empty battery compartment on the back of the keypad as shown in Figure
2.25.
NOTE: A wired keypad opens as shown, but a cable passes through the battery compartment
cover.
Figure 2.25. Opening the Keypad
Step 3
Find the 4 jumpers located along the latching side of the battery compartment. These jumpers set
the keypad protocol and other settings so that the keypad functions in a certain manner.
Step 4: Set the Jumpers
Set the jumpers as shown in Figure 2.26. Take care to refer to the correct part of the drawing - IR
or wired (optional). Use tweezers or needle-nose pliers to remove and replace each jumper as
necessary.

INSTALLATION AND SETUP
zJ1jumper: For either remote, set between pins 1 and 2 to set as Protocol “A”. Set between
pins 2 and 3 to set as Protocol “B”.
zJ2jumper: For either remote, set between pins 2 and 3 as shown; otherwise, the projector
will not respond correctly to keypad commands.
zJ3jumper: For the IR remote, make sure that the jumper is set between pins 2 and 3 as
shown. For the wired remote, make sure that the jumper is set between pins 1 and 2 as
shown.
zJ4jumper: For the IR remote, make sure that the jumper is set between pins 1 and 2 as
shown. For the wired remote, make sure that the jumper is set between pins 2 and 3 as
shown.
Step 5
Replace battery compartment cover. Plug into projector (wired keypad only) and test.
Figure 2.26. Locating and Setting the Jumpers
NOTE: A wired keypad can be converted into an IR remote keypad, and vice versa. Follow the
settings shown above, adding or deleting the cable and batteries as required. The cable with 3-
pin XLR connector is available separately from your dealer.
SHORTCUT METHOD:
You can also issue software protocol settings through the keypad. These software commands
will be lost when the keypad is either unplugged or when a battery is removed - the keypad will
revert back to the hard-wired jumper settings (see above) until you enter the software com-
mands again.
Press                                     = Protocol “A”
Press                                     = Protocol “B”

INSTALLATION AND SETUP
NOTE: If you change any keypad to a new protocol and the projector stops responding, the 
projector may be set to a conflicting protocol. Use the projector’s built-in keypad to access the
Communications menu. Under “Front IR” or “Back IR” or “Wired Keypad”, select the protocol
that matches the new protocol of the keypad at hand. The projector should now respond 
properly.
Converting a Keypad
If desired, you can convert an IR remote keypad into a wired remote keypad and vice versa.
TO CHANGE FROM INFRARED TO WIRED:
zRemove battery compartment cover from back of keypad.
zRemove batteries.
zWait 1-2 minutes.
zPlug the keypad cable (available separately) into the empty battery com-
partment. Make sure that the battery cover is notched smoothly to accom-
modate the cable.
zSet keypad protocol as desired, using “wired” jumper settings.
zReplace battery compartment cover.
zPlug into the 3-pin XLR port at the rear panel of the projector.
TO CHANGE FROM WIRED TO INFRARED:
zUnplug the keypad from the projector.
zOpen the keypad back and unplug the keypad cable.
zWait 1-2 minutes.
zInstall batteries (see Section 4).
zSet keypad protocol as desired, using “IR” jumper settings.
zReplace battery compartment cover.

3.1 Overview
This section explains how to use the projector once it has been installed. Please read through these
pages before using the projector for the first time. An understanding of projector features and how
to access them will help you to take full advantage of the capabilities of the projector within min-
utes.
NOTE: Installation involves locating the projector and adjusting it for use at that location. If you
have not yet installed the projector, refer to Section 2, Installation and Setup.
3.2 Projector Basics
Most projector functions and adjustments are entered through keypad commands that either con-
trol the projector directly or activate a system of intuitive menus. Variations in settings can be
defined and retained in the projector’s internal memory as a custom channel, with up to 99 dif-
ferent channels possible.

Components / Features
ZOOM- Adjusted manually, the lens barrel of a zoom lens rotates to adjust the size of the image 
without moving the projector. Minimum and maximum image sizes depend on which zoom lens 
is installed.
FOCUS- Adjusted manually. Focus adjusts the sharpness of the image at the current throw dis-
tance.
LENS OFFSET- Adjusted manually, vertical and horizontal offsets shift the lens and move
the image up or down and left or right.  Installation and Setup for the offset ranges for any
given lens.1.
SHUTTER- Closing the shutter blocks the lens internally and turns the image to off. The shut-
ter is controlled with the keypad.  (OPTIONAL)
LAMP SIDE PANEL- For accessing the interior lamp door and replacing the lamp module.
NOTE: Lamp replacement requires a qualified service technician.
FILTER INSIDE PANEL- Louvered grille for air intake. Remove to replace air filter.
COMPOSITE/S-VIDEO INPUT- Accepts a composite video and S-Video signal from
devices such as VCRs.
RGB INPUT- Accepts RGB and sync signals from devices such as the VHD Ultra Controller
or a computer, as well as YPbPr component signals from a DTV decoder.
RS-232 SERIAL INTERFACE (WITH LOOP THROUGH)- Allows one or more projectors
to be remotely controlled by a computer or controller.
RS-422 SERIAL INTERFACE (WITH LOOP THROUGH)- Allows one or more projectors
to be remotely controlled by an RS-422 compatible computer or controller. RS-422 communica-
tions can travel greater distances than can RS-232 communications, but require RS-422 compat-
ible equipment.

OPERATION
AC LINE CORD INPUT- The projector requires AC power of 100 to 240 VAC, 50 to 60 Hz
(11.5 amps @ 100 VAC, 5.5 amps @ 220 VAC). Always use the line cord that is supplied with
the projector-the projector requires this high-current 13A rated cord. See complete power speci-
fications in Section 5.
WARNING
Do not attempt operation if the AC supply is not
within the specified voltage and power range.
STATUS/POWER LEDS- Two LEDs (light emitting diodes) located in the lower right corner of
the rear connector panel indicate projector “Status” (top) and “Power” (bottom). During normal
operation, the “Power” light is steady green and the “Status” light flashes green each time a key
is pressed or when the projector receives a serial command. Use the following as a guide:
Figure 3.2. Reading the Status LEDs 
NOTE: A steady red power light accompanied by a coded pattern of red and yellow flashes from
the status light indicates an internal system error. Consult the rear LCD display for an explana-
tion, and see 3.9, Error Conditions.Should the problem persist, contact your Runco dealer.
REMOTE WIRED KEYPAD CONNECTOR (3-pin XLR)- For optional tethered remote control
of the projector.
LCD STATUS DISPLAY- Visual feedback for monitoring projector activities and status.
INFRARED SENSORS- The infrared (IR) sensors on the front and rear of the projector receive
infrared signals from the IR keypad for remote control of projector functions. For proper opera-
tion make sure that these sensors are not blocked.
HARD RESET- Emergency access for powering down the projector in the event of a system
failure. Insert a pen point or small screwdriver.

OPERATION
3.3 Using the KeypadThe keypad appears in two locations:
z Infrared (IR) Remotefor wireless control up to 100 feet away
z Wired Remote(optional) tethered to the rear of the projector
While each keypad is identical in layout and provides complete control of the projector, you may
find one keypad more convenient than another for your specific installation and application. 
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, point the keypad either
toward the screen or toward the front or rear of the projector. One of two sensors on the projec-
tor will detect the signals and relay the commands for internal processing.
Wired Remote-OPTIONAL-
The wired remote keypad connects to the 3-pin XLR jack via a 50 ft. cable. It is recommended
when:
z the lighting conditions are unsuitable for proper IR transmission
z you want to use a separate keypad for each projector in a group
Guide to Keypads
Keep in mind the following guidelines:
1)Press keys one-at-a-time; there are no simultaneous key presses required.
2)For any key having an “*”(         for example), hold the key for approximately 1 second in
order to toggle the function with a single key press. For other keys (or to use a “*” key in con-
junction with                    ), a momentary press similar to a mouse click is sufficient.
3)Press the “lightbulb key” to temporarily illuminate the backlight for the keys without sending
any other command.
4),         ,         , and repeat their “arrow” actions when held down. For other keys,
release and press again to repeat an action.
5)If you press a key while the projector is busy with another action, such as during a power-up,
the key press may not take effect.
Keypad Commands
Specific keypad commands are explained below:
Power ON/OFF
Press and hold for approximately 1 second to turn the projector on or off with a single key press.
Or press         followed immediately by        or       if you want to guarantee the correct toggle
(useful if you are unsure of the present status).
NOTES: 1) Whenever the projector is turned off, the lamp cooling fans remain on for about five
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.

as entering 
Input
Press                  when you want to display from a specific source location, such as a switcher
connected serially to the projectors switcher port. The first digit represents the number you have
assigned to your switcher (usually 1-9, or 0 for one of the four inputs on the projector). The sec-
ond digit represents the switchers slot number (1-9). For example:
= display data from switcher 1, slot 2.
NOTES: 1) Although you dont need to use the input key, you can also use        to access the four
input slots on the projector itself: use   as the first digit (representing the projector as the
switcher), then     ,    ,     ,or as the second digit (the desired input slot number).    in combi-
nation with higher numbers is an invalid entry. 2) See 3.5, Using Channels and Inputsfor a
detailed explanation of inputs.
NOTE: key behavior during a presentation depends on whether or not the Display Channel
Listoption is selected in the Preferencesmenu. You can choose to have on-screen feedback when
you press       , or you may prefer to enter the desired source location blind, i.e., without on-
screen feedback. See Preferenceslater in this section.
Channel
Press         to select a specific source setup (channel) defined and stored in projector memory.
Once you enter a 2-digit channel number (or, if there is a list displayed, highlight it and press       
), the display will automatically change and update according to the numerous setup param-
eters defined for that channel.
NOTE:         key behavior during a presentation depends on whether or not the Display Channel
Listoption is selected in the Preferencesmenu. You can choose to use a scrollable list of chan-
nels when you press       , or you may prefer to enter the desired channel number blind, i.e.,
without on-screen feedback. See Preferenceslater in this section.
Standby 
Press       and hold for approximately 1 second to blank all display and mute the audio output
while keeping the projector in a warmed-up and ready state. Or quickly press and release
and follow immediately by                     if you want to guarantee the correct toggle (useful if you
are unsure of the present status). Note that the lamp and electronics remain ON in standby mode,
even though the image turns to black and most functions are disabled. To leave standby, press and Input2

NOTE:       does notsave changes within text editing boxes (including number editing of a
slidebars) or within pull-down lists. It acts as a cancel in these cases.
Arrow Keys 
The arrow keys have a variety of functions depending on the situation. Some typical uses are
described below. See also Editing Text later in Section 3.
zUse          or           to change a slidebar value-hold as desired for contin-
uous adjustment (note the adjustment increments and range depend on the
parameter being adjusted).
zUse          or          to change to a different option within a pull-down list
without having to display the list first.
zUse          or           to jump between pages, such as in Helpor lengthy
pull-down lists.
Use the                     keys to navigate within a menu, pull-down list or text box, or to increase 
decrease the value in the second (bottom) slidebar of a double slidebar.
You can also use in conjunction with certain togglekeys-i.e., those including an
asterisk symbol-to ensure a toggle onlyin the desired direction. When turning the projector on,
for instance, you may be too far from the projector to know whether it is really off or if the
shutter is merely closed. If you press        and hold it for approximately 1 second in hopes of
turning the projector on, the projector will actually turn offif the projector was already on.
Instead, to avoid the risk of toggling in the wrong direction, quickly press and release normally
the function key you wish to toggle (in this case         ). Then immediately (within 2 seconds)
press either       as desired. The specific toggle will occur.
Toggle keys are labeled with an asterisk on the keypad. They are listed below:
z+ = close the shutter (OPTIONAL)
+ = open the shutter (OPTIONAL)
z+ = put the projector in standby mode
+ = leave standby
z+ = turn the projector on
+ = turn the projector off
