1. From the Main menu, select  ArrayLOC > Bright/ColorLOC  Configuration to access and 
work with the capabilities of the projectors in the array.
2. Set the  Minimum Brightness  value (as a percentage of the target brightness). This setting 
indicates the minimum brightness that the array targets, and the threshold for alerts from 
projectors that cannot achieve the minimum. 
3. Set the  Minimum Gamut  value (as a percentage of the target gamut). This setting indicates 
the minimum gamut that the array displays, and the threshold for alerts from projectors that 
cannot achieve the specified minimum. 
Projector Capability  identifies 
the projector capability with respect to the array common 
color gamut as defined by  Color Target and Brightness Target . 100% indicates the 
projector meets the target. A greater number indicates that the projector can exceed the 
target. A smaller number indicates how much the projector falls short of meeting the target.
The failure point for maintaining minimum gamut is calculated as:
For example:  Where b is the length of the line from the 
target white point to the target color primary, and  a is the 
length of the line from the target white point to the 
intersection of the projector capability gamut line and the 
line from the target white point to the target color primary.
4. Set the  Warning Brightness Threshold  as a percentage 
of the brightness target. Making changes to this option, 
recalculates the internal brightness warning level, and if 
warnings are enabled checks the current common 
brightness capability against the brightness warning level. 
When the common brightness reaches the warning level, all 
projectors in the BCLOC group issue the warning message, 
Projector fails to meet warning brightness 
threshold of xx%; capability xx%. 
5. Set the  Warning Gamut Threshold  as a percentage of the target gamut. Making changes to 
this option, recalculates the internal gamut  warning level, and if warnings are enabled, 
checks the current common gamut against the gamut warning level. When the common 
gamut falls below this level, all projectors in the BCLOC group issue the warning message, 
Projector fails to meet warning gamut threshold of xx%; capability Rxx% Gxx% 
Bxx%.
Adjust Projected White and Primary Colors for the Array
User-defined target color spaces allow color  primaries and white points to be adjusted 
independently. For example, you can select the target color space  User 1, copy the values from the 
target color space  Factory, leave the color primaries, and adju st only the white point. All the 
settings for a user-defined color space are editable.
i 
Projectors that fall below the minimum are ex cluded from the calculations of the common 
gamut and common brightness. If the projec tor falls below the minimum, the projector 
operates at its current brightness and gamut.  LED drive level changes and electronic color 
correction is not done.

Use this menu on the master projector to configure the target color space settings. This is the 
recommended way to control the color space for the projector and array
. The settings apply to the 
projectors in the same ArrayLOC group. These  settings are enabled on master projectors only. 
1. From the Main menu, select  ArrayLOC > Array Color Target .
2. From the  Target Color Space drop-down list, select a user-defined color space. Once selected 
the last saved red/green/blue/xy values associated with the selection are displayed.
 
3. Target Red x/y , Target Green x/y , Target Blue x/y  displays the color values associated 
with the selected target color space. Only values for user defined color spaces ( User 1 through 
4 ) can be changed. Changes to these values up date the associated color space chromaticity. To  
use another color space as a starting point, select a source color space from the Copy Color 
Space From list. When  Target Color Space is set to Maximum , the values reflect a color 
space larger than capable for the best array color saturation. The values may not reflect real-
world colors
4. To set the white point for the array using one of the following methods: • Select a user-defined white point from the  Select White Point drop-down list. Changing 
this option un checks  the  Set White to Color Temperature  check box and updates the 
Target White x/y  values and the White Color Temperature .
Target White x/y  displays the white x/y values associated with the  Select White 
Point  option. Only values for user defined white points ( User White 1 through 4) can be 
changed. When  Set White Color to Color Temperature  is checked, the values are 
calculated based on the specified  White Color Temperature.
•Check the  Set White to Color Temperature check box to recalculate  Target White x/
y  values based on the specified standard  White Color Temperature. This option is 
available only when  Select White Point  is set to one of the user-defined options,  User 
White 1 through  4. This option is unchecked automatically when you change the  Select 
White Point  option.
5. From the  Copy Color Space  From  drop-down list select a user-defined color space. The 
Target Red x/y , Green x/y , Blue x/y  values are updated based on the color space selected 
from the list. This option is available only when  Target Color Space is set to one of the user-
defined options,  User 1 though  4.
6. To adjust the target brightness for the array, adjust  RGB Brightness Target on the master 
projector. For maximum brightness, set the  value to a large number, such as 40,000.

7. If the array appears matched across all projectors for color and brightness, color setup is 
complete. 
If further adjustment is required, see  Fine-tune Whites, White Brightness, or Primary Colors  
on page 43.
Fine-tune Whites, White Brightness, or Primary Colors
The Projector Color Adjustment menu lets you fine-tune color or brightness for individual projectors 
to accommodate any projector-specific optical elem ents (for example projection lens, fold mirrors, 
screen properties or ambient lighting). The following steps outline color adjustments using 
projector color settings until the colors appear to matc h the rest of the projectors in the array. Color 
adjustments are evaluated by eye; however, a colo r meter can help determine the change required. 
For information about using a color meter with this procedure, see  Fine-tune Projector Colors with a 
Color Meter  on page 44.
1. From the Main menu, select  ArrayLOC > Projector Color Adjustment . 
2. Use the  Target Color Space  option to change the color space.  Changing this option applies the 
red/green/blue x/y values associated with the selected option. It also updates the red/green/
blue components of each color on this menu.  Selecting one of the user-defined color spaces 
displays the last saved adjustment values.   
3. Use the Red Part/Green Part/Blue Part of “x” options to make projector specific color  adjustments to the selected  Target Color Space.
4. Use the  Copy Adjustments From drop-down menu to copy the  adjustment values from the 
selected color space to the current color space. 
Adjustments are specific to the target color spac e. If the color space is changed for the array, 
projector adjustments can be copied from the old target color space and fine-tuned again.
5. Use the  White Brightne ss Adjustment option to adjust the RGB brightness for the projector.
Configure ArrayLOC
Select the projector-to-projector communication network configuration for all Ethernet messages 
related to ArrayLOC functions, including ArrayL OC messages, and BCLOC messages. Make sure all 
projectors in an array are operating on the same network, either the Control Network or the 
ArrayLOC Network. See  ArrayLOC Network Configuration  on page 24.
1. From the Main menu, select  ArrayLOC > ArrayLOC Configuration .
i 
• The Target Color Space option is enabled only  on the master projector. All other projector-
specific color adjustments on this menu ar e available on all projectors at all times.
• ColorLOC Status displays ColorLOC warnings and errors.
i 
• If at any time you want to reset the color values to the color adjustment default values (0  or 100) select Clear Adjustments.
• To reset the red part / green part / blue part  of each color to the default values set at 
factory select the Reset Current Adjustments to Default option.

2. From the  ArrayLOC Network  drop-down list select from  ArrayLOC Network or Control 
Network . 
3. Assign an  ArrayLOC Group  to the array. Only projectors in the same ArrayLOC group 
automatically achieve a common gamut and brightness.
4. Use the Synchronized keys, Test  Pattern, Color Enable option to set the projector to listen 
for remote keystrokes through the ArrayLOC network and the master projector. All 
synchronized projectors respond to the same keystrokes. Double key strokes may not register 
correctly, use alternate key commands instead.
A synchronized projector automatically starts listen ing to its IR receiver if the master projector 
becomes unavailable, for example if it goes into Standby mode. Independent indicates that the 
projector listens to its own IR remote receiver. It  is the default option. Change this setting for 
each projector individually. 
5. When you want to sync the particular feature for all the projectors in the ArrayLOC group, set  fields 4 to 7 to  Synchronized.
Use the  Independent  setting to make changes to each projector individually independent of 
the master projector. The default setting for each selection is  Synchronized.
Fine-tune Projector Colors with a Color Meter
To use a color meter for projector color adjustments, follow the instructions in  Fine-tune Whites, 
White Brightness, or Primary Colors  on page 43. Use the information below and a color meter for 
the XXX Part of YYY adjustments.
1. To note the xy color values reported for the common gamut, navigate to  Main Menu > 
ArrayLOC  > Array Color Target . 
2. Measure the projected primary color with the meter and compare the metered values to the  common gamut values.
Use the adjustment guide to  determine how to adjust the Projector Color Adjustment  values to 
correct the differences. The adjustment guides ar e color coded. The suggested corrections are also 
color coded, and reflect the direction of the change,  + or -. For example, if the measured red is 660, 
325 and the Common Gamut value is 640, 330 then  the measured x is high (High X) while the 
measured y is low (Low Y). The corresponding quadra nt of the RED guide indicates +G (increase green) 
to correct the mismatch with other projectors.

Image Settings
Adjust Gamma Settings
To access the Gamma Settings, select  Image Settings > Gamma Settings . The system offers 
two types of gamma correction. Gamma correction can  be applied to a specific source to correct for 
luma encoding. This is the  Gamma control. The system also provides a global  Gamma Correction 
control. The global control offers an offset applied  to all displays. This offset is used to compensate 
for changes in ambient conditions, such as ambi ent light in the room and projected material.
Gamma Correction
Gamma Correction applies a global offset to all gamma settings for each input. This offset is used to 
compensate for changes in ambient conditions, su ch as ambient light in the room and projected 
material. It affects the shape of the curve by pe rforming a linear transform toward a gamma curve 
of 1.0 while the control is increasing and likewis e a linear transform toward a gamma of 3.0 as the 
control is decreasing. To correct a particular source only, use the  Gamma control.
i 
To access the gamma settings for your secondary input select Input and Switching > 
Secondary Image Settings > Secondary Gamma Settings. 
i 
Gamma correction should only be adjusted to comp ensate for ambient conditions.

Select Gamma
Select the base gamma table 
for a given source. Select 
from one of the standard 
tables, a custom gamma 
function, or select an 
arbitrary gamma table that 
has been downloaded to the 
projector. A separate PC 
utility is needed to do this. 
The 2.22 curve is a power 
curve typically used to 
encode graphics and video sources. The  Standard curve (auto setup default) is a modified 2.22 
curve with a small linear section in the black that enhances the detail in darker areas of the 
projected content. Typically  Standard or 2.22  is used for all sources. Alternatively, if neither 
default is ideal, apply a simple gamma curve by de fining a custom power function and slope. Select 
Gamma Function  to enable the function and slope controls. 
Gamma Function
Defines the base gamma power curve used when  Gamma is set to  Gamma Function . This value, 
combined with the Gamma Slope  setting determines the base Gamma table to be used as the custom 
base table. The curve is generally a power curve wi th a small linear segment at the bottom defined by 
the slope.
Gamma Slope 
This control defines a slope to be used for the base custom Gamma table for a small section at the 
bottom of the curve. This slope can be used to bring  in or out the low level blacks in the image. This 
slope, combined with the gamma function, defines the custom Gamma table.
Configure the Display
The Configuration menu provides access to diagnost ics, calibration tools and the Service submenu 
(password-protected). Use this menu to define  general operating parameters and communications 
with other projectors and equipment, and to  access other advanced processing and image 
adjustments affecting overall performance. To access this menu select  Configuration from the 
Main menu.
i 
For complex non-standard gamma curves, a us er-defined curve created externally and 
downloaded to the projector can be used (r equires separate PC-based Arbitrary Gamma 
software application to create the table, and the WebUI to download it). If any of these 
special user curves have been installed, th eir names appear in the Gamma drop-down list.

Output Options
Change Screen Image Orientation
1. From the Main menu, select  Configuration > Output Options .
2. From the  Screen Image Orientation drop-down select from front, rear, front inverted, and 
rear inverted.
Control Frame Locking
Use frame locking to select how the projector controls the output frame timing based on the input 
signal. 
1. From the Main menu, select  Configuration > Output Options .
2. From the Frame Locking  drop-down menu select Frame Lock to lock output image frames to 
the primary input or select  Frame Lock Secondary to lock output images to the secondary 
input. 
Set Frame Delay
This control delays the output signal timing relati ve to the input signal timing by a fraction of a 
frame. In a multi-projector system this control may  be used to adjust the output timing relative to 
the input so that all the projectors display the image at the same time. This allows for a seamless 
display across projectors. 
Actual Frame Delay
This control indicates the dynamically calculated,  effective minimum frame delay for the projector. 
Power Management
To access the Power Management menu select Configuration > Power Management  from the 
main menu.
Auto Power Up
If there is an AC power interruption while  Auto Power Up is enabled, the projector resumes 
operation in the same state as it left off. If th e light engine is On and an image showing when AC 
power is lost, the projector automatically powe rs back up, and an image shows when AC is 
restored.
Auto Shutdown Enable
When  Auto Shutdown Enable  has been selected, and no projector activity has been seen for the 
activation time-out period, the projector enters a  power-saving mode in which the light engine dims 
and the shutter closes. If this condition persists for an additional time-out period, the projector

automatically goes into Standby mode. The presence  of any activity within this combined interval 
cancels auto shutdown and returns the projector to normal operation. 
Turn Off Image After (min)
This sets the activation interval (in minutes) for auto shutdown. If all activity (input signals, Web or 
Serial port activity key presses) is lost for this  length of time, and auto shutdown is enabled, an 
auto shutdown cycle begins.
Enter Standby After (min)
This sets the interval (in minutes) between star ting Auto Shutdown and entering Standby mode. 
Once Auto Shutdown has been entered, and all activity continues to be absent for this interval, the 
projector automatically enters power Standby mode.
Stealth Mode
Check this option to operate the projector with  the status LED display on the input panel powered 
Off. The status LED is powered Off during operatio n only. In Standby mode, the status LED displays 
codes normally. Operating in Stealth mode is recommended when images are displayed using only 
non-visible (IR) light. In this mode any visible lig ht from the projector can noticeably reduce image 
contrast as seen through NVG devices.
Fan Assist
If necessary, use the slide bar to increase projecto r fan control. An increase to this setting makes 
the fans quicker to react and run at a higher intensity. The default setting is 0. Increase the setting 
when operating in high ambient conditions. This may help ease thermal problems in such 
environments. Fan assist increases noise levels.
Change Date and Time
To change the current year-month-day, hour-minute-second go to  Configuration > Date and 
Time . Changes made reset the projector real-time clock.
Communications
The Communications menu allows you to define and control how single or multiple projectors are 
linked with each other and with a controlling device. See  Serial Communication on page 62. To 
access this menu select  Configuration > Communications  from the Main menu.
Serial Options
Baud Rate: Determines the speed of communication to  and from the projector on the RS232 or 
RS422 links. The maximum rate for RS232 is 115200; for RS422 it is 19200. Set the baud rate to 
match that of your controlling device, such as  your PC. See the documentation for the controlling 
device to determine the baud rate. In an existi ng network of projectors, if you discover that a 
projector has a different baud rate, use the pull-down list and select the correct baud rate.  Serial 
communication is always eight data bits, no parity.

Serial Mode : Select the serial data mode. The mode in cludes the number of bits, the parity and 
the number of stop bits.
Serial Protocol : Select the protocol used on the serial communications port.
Projector Address
Enter a number up to three-digits in length (such as “001”) to assign or change a number to the 
projector currently in use. If the current proj ector already has a number assigned, that number 
appears here. Numerical identity for projectors enables you to communicate with a single projector 
within a multiple-proje ctor application. See Proj on page 38. If you make a mistake in assigning or 
changing the projector number, press  Exit. 
Network Routing
Separate : Select (factory default) to keep RS232, RS422, and Ethernet messages on their 
respective paths instead of being broadcast to the other types of ports. 
RS232 and RS422 Joined : Messages originating from an RS232 or RS422 controller are relayed 
to all RS232 or RS422 ports. Any Ethernet communication, however, does not.
RS232 and Ethernet Joined : Messages to and from the RS232 ports are also be relayed to the 
Ethernet port, and vice versa. Any RS422 communications is isolated. In the case of multiple 
Ethernet sessions over the single Ethernet conne ctor, input on the RS232 port is relayed to all 
Ethernet sessions; however, input from any Ethernet session is only relayed to the RS232 ports.
All Joined : All messages reach all ports, regardless of type. In the case of multiple Ethernet 
sessions, input on one Ethernet session is relayed to all other Ethernet sessions, as well as to the 
RS232 and RS422 ports.
Ethernet Settings
To access the Ethernet Settings window select  Configuration > Communication  > Ethernet 
Settings  from the Main menu.
IP Address : Enter a valid and unique IP address for use on the network to which the projector is 
currently connected. This address overwrites any pr evious IP address such as the projector factory-
defined default. It takes approximately ten second s for the projector to respond to its new address.
TCP Port : On some Ethernet networks, firewall restrictions may require that the port number of 
the projector be changed from its default of 3002.  If so, enter a new valid port number here. It is 
highly recommended not to use a port number below  1000, as these ports are typically reserved for 
and used by common IP applications.
