Overview

Description

BlendPRO accepts RGB video from up to 4 high-resolution video sources and processes the video for display in multi-projector widescreen format. Processing includes data doubling to generate overlapped projected regions as well as edge-feathering of the overlapped images. The amount of data overlap and the edge-feather transfer function are user-programmable. BlendPRO allows standard high-resolution images generated with applications such as

Microsoft Powerpoint or Macromedia Director to be displayed in a multi-projector widescreen format. Standard multihead graphics cards can be utilized for output. The product completely eliminates the need to precondition source material during the content creation phase. BlendPRO is compatible with all Folsom Research seamless switcher/scaler products, including ScreenPRO, ScreenPRO PLUS, VFC-2200, VFC-2200DE and controllers manufactured by Folsom Research.

Typical Operation

BlendPRO allows you to easily transition from presentations involving independent screens to those where multiple projectors are used to create seamless widescreen presentations. Typical widescreen applications are illustrated in the BlendPRO connectivity diagrams in Figures 2.2, 2.3, and 2.4. Input source selection, seamless switching, image processing and operator control functions are performed by a Multi- Screen Presentation System such as

ScreenPRO PLUS. The outputs from the ScreenPRO PLUS system are processed by BlendPRO, which performs data doubling and edge-feathering on the images to drive multiple projectors. BlendPRO makes data overlap and edge-feathering functions completely transparent to the operator. Test patterns are provided to support projector alignment. BlendPRO simplifies the entire process of preparing for a widescreen event including content generation, set-up, and real-time control.

Overview of Edge-Blending Technology

Edge-blending technology is becoming increasingly popular for supporting very large high-resolution displays. The technology is very flexible and can support a wide range of screen configurations. A typical three projector system is illustrated in Figure 1.1. As shown in the figure, multiple projectors are used to project on a common surface to create one high-resolution image. The creation of a seamless image requires careful attention to detail. High quality results are dependent upon a system-level approach that integrates content creation, video processing, projector setup and system adjustments as described below.

Fig 1.1 Typical three projector system

Content Creation

When projecting an image across a large screen, it is very important to maintain sufficient resolution to obtain a crisp, clear image from the perspective of the viewer. Generally, high-resolution source material needs to be used to maintain image content that is pleasing to the eye. There are two methods that are commonly used to generate widescreen source material, each of these methods is explained below.

Use of a Single High Definition Image

High Definition source material has a resolution of 1920 pixels x 1080 lines. Images of this type can be reformatted to drive multiple screens as indicated in Figure 1.2. The reformatting is usually performed by a seamless switching system such as the Folsom ScreenPRO PLUS. Reformatting in the seamless switcher allows the resultant images to be processed for providing seamless switching, integration of picture-in-picture video and keying features. Note that the input image can be effectively spread to multiple screens, however, the inherent resolution of the output image remains that of the source material, 1920x1080 pixels.


Fig 1.2 HD Source material formatting

Use Of Multi-Head Graphics Boards

Standard multi-head graphics boards can be used to directly generate image data to drive multiple screens. In this case, the computer generates one very high-resolution image and the image is output by multiple graphics heads.

The inherent resolution of the output image is limited only by the processing power of the multi-head graphics board.

Image resolutions with up to 6400 pixels of horizontal resolution can be achieved with current technology.

Video Processing

The purpose of the edge-blending process is to provide a smooth transition for the eye over the blending region. To provide a smooth transition, identical image data from two different projectors must be superimposed and the output from each projector must be edge feathered to provide seamless optical mixing of the two source images. There are two video processing functions that are required specifically to support wide-screen edge blended displays, Image

Overlap and Edge Feathering.


Image Overlap

Source images consist of a single HD image that has been split into multiple channels (see Figure 1.2) or a series of images from a multi-head graphics card. In either case, the source images must be re-formatted to provide image overlap to support the edge-blending process. The Image Overlap processing is illustrated in Figure 1.3. The width of the blending region determines the amount of required image overlap and this must be programmable to support different applications.

Fig 1.3 Image Overlap & Data doubling illustration

Edge Feathering

The overlapping image data in the blend region must be edge-feathered to support a seamless optical blend. The transfer function must be programmable to support blend regions of different widths and adjust to different video characteristics. A typical blend function is illustrated in Figure 4.


Fig 1.4 Typical blend function

Projector Setup and System Adjustments

Accurate projector setup is essential for creating seamless images. The projectors must be precisely aligned to overlap the adjacent blending regions. The brightness, contrast and color balance of the projectors must be adjusted to provide a uniform appearance across the entire screen. Custom test patterns and an alignment procedure are used to simplify this process and provide an optimal result. It should be noted that mixing and matching projectors is not recommended as it makes the adjustment process much more difficult.

Typical System Configuration

The system configuration for a typical wide-screen display application is shown in Figure 1.5. The system includes a

ScreenPRO PLUS Seamless Switching and Control System as well as the BlendPRO Wide-Screen Image

Processor. The ScreenPRO PLUS console provides fully integrated control for setup, adjustment and real time control of all image-processing features. Image source material may be derived from a single HD source or from a multi-head graphics engine. Video sources are routed via the internal router to the Video Processing boards within the ScreenPRO PLUS. The ScreenPRO PLUS provides seamless switching capabilities and may be used to superimpose PIP source material onto the wide screen image. The PIP windows may be located at any position of the display even across the blend regions. The BlendPRO unit provides programmable image overlap and edgefeathering functions to support a fully seamless wide screen display. A screen shot of a typical edge blended application is provided in Figure 1.6.

Expansion In/Expansion Out connections

Two connectors on the BlendPRO use DVI-D connectors. These connectors are only used when more than one

BlendPRO is used, i.e. in applications requiring more than four projectors. The Expansion Out connector is used to send video signals in digital format from the BlendPRO controlling projectors 1-4 to the BlendPRO controlling projectors 5-8. The video information is a digital representation of the input connected to video source #4. The second BlendPRO unit controlling projectors 5-8 uses this information received on its Expansion In port as its master video source.

An overview of BlendWizard

Each application is different and there are many factors that need to be considered to optimize performance.

BlendWizard is an interactive Graphical User Interface application designed to assist users with two very important tasks:

- Entering application information to derive system configuration parameters and;

- Pre-show setup and adjustments.

BlendWizard Installation Instructions

The BlendWizard may be downloaded from the Folsom Research web-site or FTP server. The following step-by-step instructions will allow you to install Folsom Research Inc’s BlendWizard to a Windows NT/2000 PC.

Follow the steps below and use the figures provided as a visual reference to the images being displayed during the installation process.

3. The following dialog box will appear

The setup application is now ready to install the BlendWizard application. Click the ‘Next’ button to begin file transfer.

4. After successfully transferring the file to the directory specified, the following dialog box will appear:


Click the ‘Finish’ to exit the installation setup.

5. A shortcut to the BlendWizard application has been placed in the Windows desktop. The BlendWizard application can also be reached from the Start Menu (Start -> Folsom Research -> BlendWizard.)

Using BlendWizard to Derive System Configuration Information

The first step in planning for a seamless wide screen presentation is generally to examine the size of the required screen and to determine the type and number of projectors to be used. During this process, parameters such as the width of the blend region are determined and the mapping of source material to the output image is defined.

BlendWizard is an interactive computer program that allows users to enter application-specific information to derive system configuration parameters. An overview of the operation of BlendWizard is described below. Detailed information on the operation of BlendWizard is also provided below.

The user interacts with BlendWizard via a Graphical User Interface. The user may enter application-specific information in any order, however, generally the user first specifies the physical size of the output screen and the resolution of the projectors that will be used. BlendWizard calculates the number of projectors that will be required for the application and provides a graphical representation of the mapping of source material into the output wide screen image. The user can interact with the program to specify parameters such as the amount of overlap desired for the blend region. The input images are properly offset to account for overlap and then placed within the Wide Screen

Blended Output window. The portion of the input image allocated to each projector is clearly shown and the associated video parameters are specified in a table. If it is necessary to adjust the horizontal size of the image, the operator may opt to add an additional projector or decrease the amount of overlap in the blend region. If the image is too wide the operator may opt to remove a projector or increase the overlap in the blend region. The result of this interactive process is;

- a plan for the placement of image data across multiple projectors and;

- a corresponding set of BlendPRO configuration parameters.

The resulting BlendPRO Configuration File can be stored and used to document the configuration of the show. The file can also be downloaded to BlendPRO to automatically configure all blending functions.

Using BlendWizard to Automate System Setup and Adjustment

Proper pre-show setup and adjustment is critical to providing a seamless wide screen image. BlendWizard has been designed to interact with BlendPRO and ScreenPRO PLUS to automate the system setup and adjustment process.

BlendWizard downloads the BlendPRO Configuration File for the application (derived as indicated in the previous


Section) to configure the BlendPRO unit. The user follows a series of instructions to perform configuration activities.

As the instructions are carried out, BlendWizard sends commands to the BlendPRO (and ScreenPRO PLUS, if applicable) to download configuration files and select test patterns to support projector setup, alignment, etc. The operator can adjust system parameters to optimize performance by returning to any portion of the configuration sequence for fine-tuning of parameters such as black level control in non-overlapped areas or edge-feathering transfer functions.


Detailed Instructions for Configuring a Wide-Screen

Presentation

1. System Configuration

Use BlendWizard to select one of the standard BlendPRO Configuration Files or to generate and store an applicationspecific file. The BlendWizard output provides the basic information required to define the system configuration.

2. Equipment Setup

Connect the image sources, BlendPRO and projection devices as required for the application. Connect the

BlendPRO remote port to an available ScreenPRO port on the ScreenPRO Plus. Connect the Controller to the

ScreenPRO Plus. Connect a laptop with the BlendWizard application installed to the Controller Serial Port (DB-9

CONSOLE). Refer to figures 2-2, 2-3, and 2-4 for detailed connection information. Turn on all the equipment.

Setup BlendPRO’s serial mode to RS-485 in the SYSTEM OPTIONS menu and select a RS-485 ID.(this setting can be found in SYSTEM OPTIONS->CONFIG SERIAL menu.) The RS-485 ID number can be set from 1 to 32. The

BlendPRO RS-485 ID in a multi-screen configuration must be set to follow the ScreenPRO IDs. In a four-screen configuration (see figure 2-2) the BlendPRO ID must be set to 5. In a five-screen Configuration (see figure 2-3) the first BlendPRO ID must be set to 6 and the second BlendPRO ID must be set to 7. In a six-screen configuration (see figure 2-4) the first BlendPRO ID must be set to 7 and the second BlendPRO ID must be set to 8.

The Controller must be turned on after BlendPRO and ScreenPRO Plus have booted completely. The Controller display will show BP: N (N being the number of BlendPRO(s) it detects.) If BP: 0 is shown, check the connection from the ScreenPRO Plus frame to the BlendPRO, make sure that the BlendPRO serial mode is set to RS-485 and the proper RS-485 ID has been selected as explained above. Reboot the Controller. When it detects the number of

BlendPRO(s) that are connected to the ScreenPRO Plus chassis, run the BlendWizard application.

3. System Configuration and Adjustments

The BlendWizard will walk you through a series of steps required to configure and adjust the system. The steps are outlined below for reference, however, BlendWizard automates much of the process.

STEP 1: Projector Clock Phase Adjustment

Set the BlendPRO to output the Pixel On–Pixel Off Test Pattern on all output channels. Adjust the sample clock phase of each projector to obtain an output image that is free of artifacts (Please refer to the operating manual for your projector for detailed instructions).

STEP 2: Projector Horizontal and Vertical Sampling Adjustments

Configure BlendPRO to output the Output Raster Box Test Pattern on all output channels. Adjust the

STEP 3: Projector-to-Projector Color Balance Adjustment

Horizontal and Vertical Position of the output image from each projector until the edges of the Raster Box test pattern align with the edges of the output display area.

Set BlendPRO to output one of the following test patterns:

BLACK (0% Gray)

GRAY 25%

GRAY 50%

GRAY 75%

WHITE (100% Gray)

HRAMP


Adjust projector Color Balance controls as required to match all projectors (Please refer to the operating manual for the projector for detailed instructions).

STEP 4: Projector Registration (Overlap and Geometry Adjustment)

Set BlendPRO to output the Projector Alignment Test Pattern. This test pattern will automatically be tailored to support the overlap specified for the edge blending regions.

Adjust the physical position of the projectors and the output size adjustments until the test patterns properly align. (Please refer to projector documentation for instructions).

STEP 5: Output Black Level Adjustment for Non-Overlapped Region (DLP Projectors)

Set BlendPRO to output the following test pattern:

Black (0% Gray)

Despite the fact that BlendPRO is outputting black video to the projectors, you will notice that the projected light intensity for the overlapped regions is greater than the intensity in the non-overlapped regions, resulting in a vertical band. This is due to the fact that the overlapped regions are hit by the light “leakage” projected from two projectors. BlendPRO provides adjustments to minimize this artifact as shown in the following figures. You will also notice two narrow and dim vertical bands on each side of the overlapped region. These bands are often called Sea-of-Mirror sidebands, or Halo by projectionists. The projected light intensity without any adjustments is shown in Figure 2-5.

Adjust the black level offset within the BlendPRO unit until non-overlapped black is visually the same as the black level in the overlapped area. This will result in the projected light intensity as shown in Figure 2-6. Note that the Sea-of-Mirrors sidebands are not eliminated with this adjustment.

STEP 6: Configure BlendPRO for 1:1 Sampling (Input Clock Phase and Horizontal Position Adjustments)

Follow 1:1 Sampling configuration and adjustment procedure for BlendPRO.

Set source (ScreenPRO/SP+) for input channel #1 to output the Burst Test Pattern. Adjust Input Clock

Phase.

Set source (ScreenPRO/SP+) for input channel #1 to output the Raster Box. Adjust Horizontal and Vertical

Position and Size.

Repeat this procedure for BlendPRO input channels #2, 3 and 4.

STEP 7: Source-to-Source Color Balance

Automatic Color Adjustment

Select the Horizontal Bars test pattern on all ScreenPRO outputs (HRAMP from the Controller or HBARS from the ScreenPro front panel). Click the Auto Color Balance button on the BlendWizard Source Setup menu. The BlendPRO will automatically color balance all inputs. This operation will take several seconds to complete. Once the automatic adjustments are done, the user may perform additional manual adjustments as explained below.


Set Source (ScreenPRO/SP+) to output the Horizontal Bars test pattern.

To adjust output #1, set BlendPRO output #1 to display Source #1 with no data doubling (ie, 100% of image is from source #1).

To adjust output #2, set the BlendPRO to output Source 1 on left side of display and Source 2 on right side of display. Adjust Source 2 to match source 1.



STEP 8: Turn on Data Doubling

The width of the blending region determines the amount of required image overlap and this is programmable to support different applications.

STEP 9: Feathering Transfer Function adjustment

Set transfer function for blended region taper. BlendPRO has adjustable curves that can be applied to the selected overlap regions. Generally, matching the gamma curve to the gamma of the output device achieves the best results.


4. Detailed Examples and Calculations of BlendPRO Parameters

The BlendWizard is designed to guide users through the process of defining a system configuration and setting up the system to provide optimal results. We realize that some users will want to understand in detail how the internal calculations are performed in the Wizard. Reviewing the details is a good way to make sure that you fully understand the image processing techniques. If you want the details, read on, however, most users can simply skip this section of the manual.

BlendWizard Calculations

The basic calculations performed by BlendWizard to derive output image parameters are described below. A typical example is used to help illustrate the input provided by the user as well as the output derived from the BlendWizard program.

Output Image Size and Aspect Ratio

Generally the first parameters entered by a user are the size of the desired wide screen output image. The operator typically enters the vertical size and horizontal size of the output image. The aspect ratio of the output image is automatically calculated. For this example we will assume:

- the wide screen image must fill a 30x10 foot screen and

- the resolution of the projectors is 1280x1024.

The calculations proceed as follows.

Output Aspect Ratio = Horizontal Size/Vertical Size

Example: Output Aspect Ratio = 30 feet/10 feet = 3.0

Note: The operator can also enter the vertical or horizontal size and a desired aspect ratio to derive the size of the screen in the other dimension.

Projector Native Resolution

The operator next must indicate the native resolution of the projectors that will be used. Typical choices include:

640x480 (4:3 aspect ratio), 800x600 (4:3 aspect ratio), 1024x768 (4:3 aspect ratio) or 1280x1024 (5:4 aspect ratio).

The BlendWizard calculates the number of projectors required to fill the output screen.

The number of horizontal output pixels viewed on the wide screen image is:

Number of Horiz Pixels Viewed on the Output Image = Proj V Res x Output Aspect Ratio

Example: Number of Horiz Pixels Viewed on the Output Image = 1024x3.0 = 3072 where: Proj V Res = Projector Vertical Resolution, in pixels

The minimum numbers of projectors that can be used is:

Minimum # of Proj = # of Horiz Pixels Viewed on the Output Image/Proj H Res

Example: Minimum # of Proj = 3072/1280 = 2.4 This number must be rounded up to the next higher integer, 3 in this case. Some of the “extra” input resolution is required to accommodate overlap regions.

The number of projected horizontal pixels required to form the output image is:

# of Projected Horz Pixels = # of Horz Pixels Viewed on Output Image + ((# of Proj - 1) x Overlap) where:# of Proj = Number of Projectors

Overlap = Amount of Projector Overlap, in pixels


Example: # of Projected Horz Pixels = 3072 + (2 x 256) = 3584

Note that in this case a default overlap of 256 pixels was assumed. The operator can adjust the overlap as required to fit application requirements and the BlendWizard will automatically respond. If the # of Projected Horz Pixels exceeds the number that can be handled with the minimum number of projectors the user will be prompted to increase the number of projectors or decrease the overlap parameter. In this case, we have sufficient pixels (3x1280

= 3840) to project the 3584 pixels required to support three projectors with an overlap of 256 pixels.

Data Doubling

In order to create a seamless image on the output display, images from adjacent projectors must overlap and the image data projected by each projector in the blend region must be identical. The two adjacent projectors must output the same image onto the overlapped region. The input and output image displays on the BlendWizard screen provide a graphical representation of the image processing that is performed to generate the display.

Figure 2-8 illustrates the screen contents that correspond to the example that we have been following here. In this example,

BlendPRO will receive input from a three head graphics processor running at 1280x1024 resolution. As indicated in the Source View Window BlendPRO will process 3328 pixels of the available input to derive the output display. The

3328 pixels will be re-formatted to drive three projectors. Projector #1 will output the full 1280 pixels derived from video source #1. In order to provide the same image content in the overlap area, Projector #2 must output the last

256 pixels of video source #1 as the first 256 pixels on the left side of it’s image. For this reason, 256 pixels from video source #1 are then followed by the first 1024 pixels of the image from video source #2 to drive Projector 2

(source pixels 1024 through 2304). A similar process occurs for the third projector where the first 256 pixels of the image projected by Projector #3 must correspond to the last 256 pixels on Projector 2 (source pixels 2048 through

2304). The remaining 1024 pixels in the output image are derived from source pixels 2305 pixels 3328. This data is shown in the Destination View Window.


Figure 2-8: Data Doubling

Aspect Ratio & Overlap

The required output screen configuration can be determined in a number of different ways by interacting with

BlendWizard. For example, consider the case in which a screen is 3 times as wide as its height, a 3 to 1 aspect ratio, and the projectors to be used are 1024x768 native resolution. The total horizontal number of pixels needed is 3x the vertical total of 768 which equals 2304. By taking the total number of horizontal pixels available (3x1024) or 3076 and subtracting the horizontal number of pixels needed, 2304, a maximum overlap of 768 pixels can be calculated. Since there are three projectors creating two overlap regions, 768

÷

2=384 pixels per overlap region. Note that the total overlap cannot exceed the number of horizontal pixels of the selected projectors.

The output configuration can also be tailored to match existing source material. Let’s say you have source material that is 16x9 or 1.777 aspect ratio such as HDTV and that the image is to be input to a ScreenPRO PLUS where it is processed to drive two 1280x1024 inputs to BlendPRO. The total number of viewable output pixels is determined by multiplying the vertical number of lines 1024 times the 1.777 aspect ratio-1024x1.777=1820. The maximum overlap region is determined by summing the horizontal resolution of the projectors 1280+1280=2560 and subtracting 1820 to yield 740 pixels of overlap. To display a HDTV image in this manner we generally recommend using two 1280x1024


projectors and setting the overlap to 640 pixels. This provides horizontal total of 1920 source pixels, which equals the native horizontal resolution of HDTV. In this case, an exact one-for-one pixel mapping can be achieved from the source material through the scaler to the BlendPRO and out to the projectors. Note that generally 56 of the 1080

HDTV input lines are omitted from the displayed image.

Pixel Mapping & Projector Alignment

Blend Pro is designed to support 1:1 pixel mapping of the input sources, minimizing the effects of noise and aliasing while maintaining the full resolution of the source image. Sample clock phase and horizontal and vertical position adjustments, similar to those found on most projectors, allow BlendPRO to be set up for accurate capture of the source image.

As with single projector applications, it will be necessary to adjust the projector's clock phase and properly size and position the input image. To aid in projector clock phase and image sizing adjustments, BlendPRO provides highresolution test patterns (one-pixel On/one-pixel Off and Output Raster Box). Once exact 1:1 pixel mapping has been set at the projectors, the next step is to use the lens shift of the projectors to move the images together to cover the overlap region. Registration test patterns are provided (grids and registration lines) and are output to reflect the proper amount of overlap and projector resolution. Great care is required when setting up the projectors; the exact distance to the screen, minimum amount of off-axis angle, and correct color calibration are all essential for a quality wide screen display. Note: to achieve good color matching between projectors, we recommend that all of the projectors be of the same type. DLP or CRT projectors are preferred. It is also recommended that all projectors have approximately the same amount of hours on the lamps.

Edge Blending

Once projector alignment as been achieved, the edge feathering can be enabled. BlendPRO has adjustable transfer function curves that can be applied to the selected overlap regions. Generally, matching the gamma curve to the projectors gamma achieves the best results. With DLP projectors, the overlap region will have a greater black level due to the light overlapping from the two projectors. BlendPRO can minimize this effect by adjusting the nonoverlapped brightness level separately from the overall brightness level. The brightness level in the non-overlapped region is raised to where it equals the intensity of the overlapped region. This helps obscure overlap artifacts introduced because black output levels are not entirely black. It is recommended, whenever possible, to avoid lower luminance levels and flat fields when creating source material.

Delay

The maximum delay through BlendPRO is one non-interlaced frame (16.6 msec when using 60hz input sources). If the input sources are already locked together, the BlendPRO introduces very minimal transport delay (a few hundred microseconds).

Source Material

Content for the BlendPRO can be created a number of different ways.

For the highest resolution backgrounds available, a multiple-head graphics card, such as a Matrox G200 MMS, can be used. For example, a quad-head card outputting each channel at 1280x1024 can provide a background image with maximum resolution of 5120x1024.

An ATI card can feed each input separately and the creation of display material can be done in Power Point or

Macromedia Director. A patch to allow a slide show for Power Point to be shown across multiple screens can be found on the internet at http//:officerone.tripod.com. When creating new material that crosses multi-screen boundaries, only the aspect ratio of the final output screen needs to be taken into consideration.

Example: Outputs aspect ratio is 4.25 to 1, DLP projectors with a native resolution of 1280 x 1024 are to be used.

The horizontal screen resolution needs to be 4.25 x the vertical total of 1024 or 4352. Simply use Power Point or

Director to create images that are 4352 x 1024 across the 4 outputs of the graphics card. The images should be left


justified, however, center-justified images can also be accommodated by using the source offset adjustments in the

BlendWizard to align the source material.

Using BlendPRO with Folsom Scalers

The use of Folsom Seamless Switcher/Scaler products with BlendPRO provides the capability to display any image source on wide screen. When displaying an image across multiple projectors to create a wide screen display, the amount of zoom required to expand the source image must be considered. Low resolution images from sources such as cameras and DVD’s do not show well when expanded beyond 2 to 1 zoom ratios and in most cases should only be used in Picture-In-Picture (PIP) windows layered over a high-resolution background. Full wide screen highresolution images can best be attained using sources such as HDTV, multi-head graphics cards, high-resolution computers and synchronized tape rolls.

Operation

BlendPRO can be controlled by using the front panel controls or by using BlendWizard. The front panel controls are described in detail in this section.

BlendWizard

We recommend that BlendPRO be controlled via the BlendWizard to automate system setup and adjustment. This software program runs on a Windows NT/2000 PC and utilizes a graphical user interface (GUI) to significantly simplify BlendPRO configuration. Minimum Windows NT/2000 resolution of 1024x768 is required.

BlendWizard Connections

BlendWizard is interfaced to BlendPRO using a serial connection. Figures 2.1, 2.2, and 2.3 illustrate interfacing a PC running BlendWizard to BlendPRO via the Folsom Multi-Screen Controller. If this interface is used, BlendPRO’s serial port must be configured for RS-485 operation and the serial port settings configured as follows:

• ID set to next value higher than the last ScreenPRO ID

• Baud 38.4K

Bit

Bit

• Parity

8

1

NONE

If two BlendPROs are used, the second BlendPRO’s serial port must be configured as above except that the ID must be one higher that the ID assigned to the first unit.

If a controller is not available, BlendWizard can be interfaced directly from the PC to a single BlendPRO using a serial communications cable from the PC serial port to the BlendPRO’s REMOTE serial port. If this connection is used, the

BlendPRO’s serial port must be configured for RS-232 operation and the serial port settings of the PC and BlendPRO must be configured for the same baud rate, data bits, stop bits, parity, and handshake settings.

There are two blend level menu modes, BASIC and ADV (ADVANCED). The Basic Blend level is sufficient for most users to configure a system and verify the equipment operation. The Advanced Blend level provides expanded controls for edge feathering functions. The selection controls the functions available in the EDGE BLEND SETUP sub-menu.

Projectors

The number of projectors to be driven by the BlendPRO is selectable with this menu item. Each BlendPRO can drive up to four projectors in a wide screen presentation. Two BlendPROs can be linked to support up to 8 screens. Set this control to “1-4” if the BlendPRO controls from one to four projectors. Set this control to “5-8” if this BlendPRO is the second of two units used to control more than four projectors. Note that a DVI cable is required to link the

BlendPRO units if more than four projectors are used.

Total Projectors

The total number of projectors being driven in a Wide-screen display application is selectable with this menu item.

The total number of projectors can be from 1 to 8. For widescreen display applications with more than four projectors, a second BlendPRO is required. The maximum number of projectors is limited based on the source material justification selected. If left display justification is selected the maximum is 8 projectors. If center display justification is selected the maximum number of projectors is 7.

Software Upgrade Instructions

Model BP-2002



Software Upgrade Instructions

Overview

The BlendPRO units incorporate the system software in a Flash memory component. Flash memory allows easy field upgrades without the need to send the unit back to the factory.

The loader utility provides the capability to update the system Flash module with the latest revision of software. The upgrade utility can be run from a hard drive (recommended) or a floppy drive. Running the loader from a floppy drive is discouraged though due to the slow speeds associated with disk access.

Hardware Requirements

* IBM compatible computer with an available COM port

* Serial cable conforming to EIA RS-232 specifications (i.e. Standard Modem cable)

(The cable should have a DB-9 male connector on one end)

Software Requirements

* Window 95/98/NT/2000

* Flash File Loader

* BlendPRO Software files

The Flash File Loader with the Software files can be downloaded from our FTP site as described below.

Connecting to Folsom Research

Folsom Research's FTP site address is: ftp.folsom.com

If you are using an FTP client, logon to our site using "anonymous" for the user name and your email address as the password (ex. [email protected]

Before installing the files, it is recommended that all running programs be properly shut down.

1. Click on the Start button and select Run.

2. Click on the Browse button and locate the "BlendPro_Rev#####_###.exe" file on your hard drive.

3. Double click on this file and then click OK to start the installation process.

4. Follow the on screen instructions to complete the install.


Starting the BlendPRO Flash File Loader Utility

After the files have been installed the BlendPRO Flash File Loader can be selected to run.

1. Click on the Start button and select Programs.

2. Find the Folsom Research folder and select BlendPRO Flash File Loader.

Preparing to Upgrade the BlendPRO Unit

1. Plug the DB-25 male connector into the port labeled “REMOTE” on the back of the BlendPRO unit.

2. Make sure the other end of the cable is attached to the available COM port on the back of the computer performing the upgrade.

3. In the loader program, click on the RS232 Config menu and select COM Port.

4. In the Communication Settings window, select the COM port the BlendPRO Remote port is attached to by clicking on the appropriate COM # choice.

5. The BlendPRO Remote port defaults to a baud rate of 38400 baud (38.4K).

Uploading Files to the BlendPRO Unit

1. Once communications have been established and verified, click on the “Open SCR file to read and upload” button to begin the upgrade process.

2. Browse to the location where the “loader.scr” file is located and click on it. Then click on “Open” to start transferring the files to the controller.

3. A TRANSFER STATUS box will open and show the status of the upload as it progresses. On the controller, the VFD will also show the status of the files being uploaded.

4. After several minutes, the loader utility will inform the user that the process is complete.

5. At this point, direct your attention to the Controller where you will see it Relaying files to the BlendPRO. Wait for this process to complete.

6. Once this is done, it is recommended that the entire system be powered cycled. You can also close the loader utility at this time.

7. Verify the new software is in the system by looking for the version numbers in the SYSTEM OPTIONS

MENUÆTECH SUPPORT menu.

8. Once you have verified the version number, it is recommended that a factory reset be performed. This is done by going to the SYSTEM OPTIONS MENU and selecting FACTORY RESET.
