System Overview

www.shsglobal.store

The STEALTH system is a modular LED display product that allows for full motion
video to be displayed on high resolution STEALTH panels.

The STEALTH panels are lightweight and rapidly deployable. A nearly 60 percent
transparent design makes it easy for set pieces or even other display devices to
remain visible behind it allowing for a number of different creative effects.

STEALTH is comprised of the following hardware components:

Chapter 1

Introduction

• VP1 - Video Processing Unit

• SP1 – Signal Processing Unit

• DD1 – Data Distribution Unit

• PDB-3 – Power and Data Distribution

• DSU – Data Supply Unit

• STEALTH Panel

The STEALTH system is capable of handling many types of video signals including:

•DVI

•SD-SDI

• HD-SDI (limited resolution, see page 2-2

• Component

•S-Video

• Composite

The VP1 takes one of the above signals and converts it to the proper format for
input to the SP1. The SP1 requires a 1024x768 Digital Visual Interface (DVI) signal at
60 Hz with high (+) or low (-) vertical sync.

(p. 3-5)

(p. 2-2)

(p. 2-4)

(p. 2-8)

(p. 2-9)

(p. 2-12)

)

NOTE

If you already have a properly formatted DVI signal for the SP1 (1024x768 @ 60 Hz),
you do not need the VP1.

Throughout this manual, screen sizes and/or pixel dimensions are referenced in the
commonly used form of 1024x768. The first number is the horizontal value and the
second number is the vertical value. For example, the DVI input signal to the VP1 is
1024 horizontal pixels by 768 vertical pixels and is represented as 1024x768.

The SP1 has 2 fiber optic outputs each with a resolution of 1024x256 pixels. One or
both SP1 outputs are connected to the DD1. The DD1’s job is to slice up the signal
into 400x80 pixel chunks which are then routed to the individual STEALTH panels
via the PDB-3.

STEALTH® v2 User’s Guide 1-2

Chapter 1

www.shsglobal.store

Introduction

The PDB-3 contains 2 DSUs, each with 4 outputs. The DSU handles the final
conversion of the video signal into 16x80 blocks which connect to a column of 5
STEALTH panels. Each STEALTH panel is an individual array of 16x16 pixels.

The following figure illustrates the basic signal flow of the STEALTH system. Unless
otherwise noted, the numbers shown are pixel dimensions.

The DSU handles the final data output to the STEALTH panels. Each DSU contains
four Scan Boards (SB) which must be addressed properly to match your
configuration.

For example, if you are going to use 8 columns of STEALTH panels the DIP switches
for the first 4 SBs must be set to 1-4. The next DSU SBs need to be set to 5-8.

Each DIP switch has 8 individual switches which allow you to set the Binary ID for
that SB. Each of the 8 individual switches can be set to On or Off. When set to the
On (up) position, there is a value associated with that setting. The overall value is
obtained by adding the individual values of switches 1-5. The following

Communication Setup

www.shsglobal.store

The following is a list of the requirements for using LedGuru software:

• Microsoft Windows-Compatible OS

•Serial Port

•Serial Cable

A USB high speed serial adapter cable, such as the Keyspan model #USA-19HS, can
be used to connect your computer to the VP1.

When LedGuru runs it automatically checks all available com ports to see if a VP1 is
connected. If one is found LedGuru asks the user if they would like to read settings
from the VP1 to ensure the software & hardware settings match.

Appendix B

LedGuru Software

NOTE

LedGuru will not launch if no com port is detected.

If LedGuru does not find a VP1 connected, the Com Setup screen is displayed as
shown in the following figure.

Figure 3.9

LedGuru Communications Setup Screen

Com ports and baud rates can be changed as required to establish
communications with the VP1. Click Check to repeat the search for a VP1.

NOTE

The default baud rate is 57.6Kbps. However, if a slower rate is required for
communication over a long cable, then speeds down to 9600 can be selected.

Both LedGuru and the VP1 remember the last selected baud rate in non-volatile
memory. Therefore, when connecting to a VP1 for the first time you may need
adjust the baud rate and hit Check to find which baud rate the VP1 is set to.

STEALTH® v2 User’s Guide B-2

Input Tab

www.shsglobal.store

Appendix B

LedGuru Software

The LedGuru Input tab allows the user to select inputs and adjust various input
parameters.

Figure 3.10

The VP1 will accept three active video inputs simultaneously: analog, SDI and DVI.
Any two of these inputs can be displayed simultaneously using the Main and
Picture-in-Picture scaling channels. Only one analog input can be selected at a
time. The signal indication for the currently selected analog input is updated when
the signal is first selected (continuous signal status polling will be added in a later
release). Note that there is only one analog input channel so only one analog input
type can be monitored at a time.

LedGuru Input Tab

STEALTH® v2 User’s Guide B-3

Output Tab

3DVI Output Adjustments

The Output tab is divided into three sections that are explained below.

Input Cropping

Adjustments over which part of the input image is selected for output can be
accomplished in the Input Cropping section of the Output tab. For example, you
can crop off the black bands at the top & bottom of certain input video images.

STEALTH® v2 User’s Guide B-4

Appendix B

www.shsglobal.store

LedGuru Software

The PAL and NTSC buttons can be used to set default crop values for these input
sources.

NOTE

NOTE

Figure 3.12

LedGuru Input Crop Settings

Care should be taken to ensure that you do not attempt to select an area which is
outside the boundaries of the input image since this will cause a corrupt output.
Make sure that if you increase VStart you also reduce VLength to ensure the
selected image area remains within the input image area.

DVI Output

The DVI Output drop down can be used to select various DVI output modes. The
SP1 requires a 1024x768 signal. The other modes are provided for use with video
systems or displays.

The SP1 requires the Invert Sync box to be ticked on the output connected to the
SP1.

Figure 3.13

LedGuru DVI Output Settings

50 / 60 Hz Field Rates

The output field rate should typically be set to match the input field rate – and
Lock to Main should be selected. This ensures the best picture quality – with no
frame dropping or repetition.

STEALTH® v2 User’s Guide B-5

Appendix B

www.shsglobal.store

LedGuru Software

NOTE

If the video input is changed from 50Hz to 60Hz you may at first see a juddering or
corrupt output. It is necessary to select the appropriate DVI Output field rate – to
match the input. Then update the Crop settings to match the input by clicking the
appropriate PAL or NTSC crop buttons.

Figure 3.14

LedGuru Field Rate Settings

Frame Rate Conversion

It is possible to convert between 50 and 60Hz output by selecting the Free Run DVI
output mode, then selecting either 50Hz or 60Hz output as required. In free-run
mode the VP1 will drop or repeat frames as necessary to match the input and
output field rates.

Picture Scaling

The size, position and sharpness of the output image can be adjusted using the
Main Picture Scaling section of the Output tab.

Clicking the Full button causes the image size to reset to fill the entire output
frame. Shift-clicking the User button saves the current size settings. Subsequently
clicking the button will recall the saved size settings.

Figure 3.15

LedGuru Picture Scaling Settings

STEALTH® v2 User’s Guide B-6

Pattern Generator

www.shsglobal.store

The internal pattern generator can be used to display various test patterns to help
identify and locate screen faults.

Most of the controls are self-explanatory.

Appendix B

LedGuru Software

Figure 3.16

When Probe Video Level is selected only the parts of the video image which have
an 8-bit video data value equal to the current Level slider setting will be displayed
at max video level (255). This allows the user to visually probe the video levels
being displayed on screen. This is useful when adjusting the video black level and
contrast controls since it shows if any parts of the output image are clipping (>255)
or if the black level is incorrectly set.

When Bit Masking is selected, the 8-bit video data is ‘ANDed’ with the Level slider
value before display. This allows the user to isolate single greyscale bits of video.
For instance, if Level is set to 128 and Bit Masking is selected, then only the MSB of
the incoming video signal will be displayed. This is useful to isolate faults which
only affect one greyscale bit within the video signal.

LedGuru Pattern Generator Tab

STEALTH® v2 User’s Guide B-7

File Load Save

www.shsglobal.store

The File Load/Save page allows the user to load and save VP1 setups to disk or
internal memory.

The VP1 stores all settings and adjustments in an active internal memory. This
memory is automatically restored when the VP1 boots up. All user adjustments are
automatically stored in the active memory.

The VP1 also provides 16 internal memory slots. These can be used to store
complete VP1 setups for later recall. The LedGuru internal memory frame allows
the user to manage these memories.

The current active memory settings can be saved to the currently selected internal
memory slot by clicking Internal Memory / Save. This will overwrite any existing
settings stored in the memory slot.

When Apply is clicked the currently selected internal memory is copied into the
active memory – overwriting any existing settings in the active memory.

Appendix B

LedGuru Software

Figure 3.17

The current active memory settings can be individually saved or loaded to/from
disk. In addition complete sets of 16 internal memory configs can be loaded and
saved from/to disk.

STEALTH® v2 User’s Guide C-1

SP1 Vertical Offset

www.shsglobal.store

The SP1 provides 2 fiber outputs, each with a resolution of 1024x256. The vertical
offsets for each fiber output port is limited by the lowest offset of it’s corresponding
DD1 output channel. Vertical offsets are changed via the SP1 front panel menus.

If any of the DD1 channels are set to a vertical offset of 0, whether they are used or
not, that fiber output will only display the first 256 vertical pixels. In order to move
the fiber output down to the 257th pixel or lower, all corresponding DD1 output
channels must be offset as well via the SP1 front panel menus.

For example, a 19 panel high screen should use the following SP1 settings:
