OptiScale Interface

OptiScale Operational Modes

The OptiScale unit has two modes of operation:

Operate

and

Setup

. You can select either of these modes of operation via the front panel interface or the RS232 control interface.

Operate Mode

In

Operate

mode, the video output signals are activated and you may control all the OptiScale parameters

(except for

Setup

restricted parameters) from the front panel, IR remote control, or serial communication commands. In

Operate

mode, all controls may be used simultaneously (that is, you may open a menu with a front panel button and make a selection using the IR remote control, and so on). The Front panel and IR remote commands invoke the OSD, and user feedback is provided for all actions. In

Operate

mode, the OptiScale 16 x 2 front panel display indicates the following information:

(SELECTED INPUT CONNECTOR) = (Input Signal)

OUT=(Output Resolution)

The front panel and IR remote control are designed to be identical in control function; that is, each button on the IR remote control corresponds directly in function to a button on the front panel. You will find a complete

list of front panel and IR remote controls and OSD operations in the


chapter. When controlling OptiScale by serial communications, all actions are performed without invoking the OSD. A complete description of the serial communications protocol is provided in the


chapter.

OptiScale powers-up in

Operate

mode. All operational parameters are retained from the previous session. A

Factory Reset returns all parameters to the default state (described in detail in the


chapter), except for the input signal. The input signal most recently used is retained as the power-up input signal.

Setup Mode

In

Setup

mode the OptiScale is in a low-power state. The output signals are de-activated and the IR remote controls (except for activate

Operate

mode) are disabled. The Setup mode is provided so that critical operational controls (such as selected output resolution) are not disturbed by inadvertent IR commands. The setup mode is indicated by the following message appearing on the bottom line of the OptiScale 16 x 2 front panel display: www.siliconoptix.com

Selects the serial communications address (from 1-32) at which this particular

OptiScale unit will respond. Address ‘00’ is reserved as a broadcast address. All

OptiScale units in a system will respond to commands sent to address ‘00’.

Please note that although you can only create a multiple unit OptiScale system if you are using the RS422 or RS485 communications schemes, you must still ensure that you correctly set the Serial Communication Box Address to agree with your control software.

Enables the serial communications for RS422/485 operation. If RS422 is disabled, the port is configured for RS232.

Cycles through all of the available OptiScale modes (see

). In addition to control by the front panel, the OptiScale Output Mode may also be controlled

by serial communications (see the


chapter for

serial communications protocols information).

Fornt Panel Display Brightness

When enabled as a Master, the OS-100 drives the output timeline vertical sync out of the composite sync #2 connector (COMP2).

When enabled as a Slave, the OS-100 expects to receive an external vertical sync one the composite sync #1 connector (COMP1).

When in Slave mode, the OS-100 will buffer the external sync from COMP1 and drive it on the COMP2 connector (allowing units to be daisy chained).

When disbled, the OS-100 accepts SDTV composite inputs on the COMP1 and

COMP2 connectors.

The brightness is adjusted by pressing the Graphics button (to increase) or the

HD Video button (to decrease).

OSD Menu Structure

The On-Screen Display (OSD) menu is the primary way of controlling and selecting functions in the OptiScale system. The OptiScale system is initially in a factory default state. Many OptiScale control parameters can be saved to OptiScale memory and retained for use in later sessions. Performing a factory reset erases these saved parameters and returns the system to the default state.

Two slightly different OSD menus are invoked, depending upon whether the currently selected Output

Resolution Aspect Ratio is 16:9 or 4:3. The biggest difference between them has to do with the way that aspect ratios are treated (see the

Aspect Ratio

section later in this chapter).

OSD Menu Controls

The OSD can be invoked in two ways, as follows: using the Front Panel Buttons or using the IR remote. The

Front Panel and IR Remote have the same buttons. The buttons are:

•

On/Setup

•

Graphics/Zoom Out

•

HD Video/Zoom In

•

SD Video YPbPr/H Zoom Out

•

SD Video S-Video/V Zoom In

•

SD Video Comp 1/V Zoom Out

•

SD Video Comp 2/H Zoom In

•

Menu

•

Up Arrow

•

Down Arrow

•

Left Arrow

•

Right Arrow

•

Enter

When pressed, the On/Setup button will toggle between Operate and Setup modes. In Setup mode, the output display of OptiScale is inactive. Setup mode is used to select OptiScale parameters that are infrequently changed (communications parameters, output resolution and lockouts), and that can cause severe effects by inadvertent selection.

On-Screen Display

The Graphics/Zoom Out button has two functions. In normal operation, this button is used as a quick select for the Graphics inputs. Pressing this button repeatedly will toggle between DVI and RGB Graphics input.

The last channel selected is remembered. If Magnify is selected from the Geometry menu, the button is temporarily re-assigned as a Zoom Out control (constant aspect ratio of Zoom Out).

The HD Video/Zoom In button has two functions. In normal operation, this button is used as quick select for the HD Video input. Pressing this button repeatedly will toggle between RGB and YPbPr color space treatment on the HD Video input. The last color space selected is remembered. If Magnify is selected from the Geometry menu, the button is temporarily re-assigned as a Zoom In control (constant aspect ratio of Zoom

In).

The SD Video YPbPr / H Zoom Out button has two functions. In normal operation, this button is used as quick select for the SDTV YPbPr input. If Magnify is selected from the Geometry menu, the button is temporarily re-assigned as a Horizontal Zoom Out control.

The SD Video S-Video / V Zoom In button has two functions. In normal operation, this button is used as quick select for the SDTV S-Video input. If Magnify is selected from the Geometry menu, the button is temporarily re-assigned as a Vertical Zoom In control.

The SD Video Comp 1 / V Zoom Out button has two functions. In normal operation, this button is used as quick select for the SDTV Comp 1 input. If Magnify is selected from the Geometry menu, the button is temporarily re-assigned as a Vertical Zoom Out control.

The SD Video Comp 2 / H Zoom In button has two functions. In normal operation, this button is used as quick select for the SDTV Comp 2 input. If Magnify is selected from the Geometry menu, the button is temporarily re-assigned as a Horizontal Zoom In control.

The Menu button is used to invoke the OSD main menu.

The Up Arrow button is used to navigate the OSD.

The Down Arrow button is used to navigate the OSD.

The Right Arrow button is used to navigate the OSD.

The Left Arrow button is used to navigate the OSD.

The Enter button is used to activate an OSD menu selection.

Chapter 5

Loading Firmware

Introduction

This chapter describes the firmware update procedure for the OptiScale system using the PC Loader.

PC Loader is the software program that controls the firmware update process—you can obtain by e-mail new features that become available and you can download them onto OptiScale. The download procedure takes about 5 minutes and prevents you from having to return your unit to the factory for simple upgrades.

The PC Loader program provides an easy and fast way to update (download) firmware into CPU

FLASH/RAM memory, via a RS232 communication line, in the OptiScale systems equipped with BootLoader firmware. During the download process, you are informed about all verifications performed by firmware and error messages are returned.

Loading HEX Files

To load HEX files follow the procedure below:

1.

Link your PC to the OptiScale system using a serial communication cable; be sure to use the proper

COM port number on the PC (see

Figure 5

). Turn off the OS-100 power using the power switch

mounted on the back of the unit.

RS-232 interface

Computer

Figure 5: RS232 Connection

2.

Run PCLoader.exe from the current directory—it will search for

.cfg

and .

dev

files only in the current directory. Be sure that if you create an icon for this application, you have the start directory with the same string as the

.exe

file path. Usually, this is a default setting provided by Windows.

3.

In most cases, the default options should be correct for proper operation. However, if there are any difficulties with the download procedure, then verify that all the configuration options are correct.

4.

Choose

Connect

from the

Communication

menu to open the COM port.


27


Loading Firmware

5.

Power on the OS-100.

6.

To load a HEX file for the firmware update, choose

Open

from the

File

menu . Open the file that was provided for the new firmware update.

7.

Begin the download process of the firmware update using the

Load Hex

button. Note the messages provided by the firmware during the loading process in the Info field.

8.

When the download process has completed (and there were no errors), power-off the OptiScale box, and power it back on to begin normal operation.

NOTE:

The errors that might be reported by the application during the startup have have two possible reasons, as follows: the current working directory is not the directory where PCLoader.exe and

PCLoader.cfg are located; or, the PCLoader.cfg file is corrupt, so the best solution is to delete this file, run PCLoader.exe again (the application builds a new .cfg file) and set up communication and device settings, which will be saved in the new .cfg file.

The above process should be all you need to load files. The remainder of this chapter is provided for advanced users only.

brd file. The only

.dev

file you should use with OptiScale is the AM29LV160D.dev file. The

.brd

file is an ASCII file with the following format

(example: OptiScale.brd file):

Manufacturer Name = AMD

Part Name = Am29LV160D

Manufacturer ID = 0001

Part ID = 22C4

Flash Start = 00000

Flash End = FFFFF

RAM Start = 00000

RAM End = 08000

BOOT SECTOR START = F0000

Loading Firmware

Loading Options

The loading options let you choose the appropriate way to load the HEX file, by choosing

Loading

from the

Configure

menu. The Loading Configuration dialog box shown in

Figure 9

opens.

These are the only loading options that you should use with OptiScale.

Figure 9: Loading Configuration Dialog Box

Loading Configuration Options

Erase Flash Memory

• No

: No Flash memory erasing commands are sent to the firmware.

• Only involved sectors

: Sends erasing commands according to the content of the HEX file.

• All sectors except BOOT

: Sends erasing commands for all Flash memory sectors, except BOOT sector, according to the current

.dev

file.

• All flash memory chip

: Sends an Erase All chip command to the firmware including boot sector.

WARNING: This option destroys the BootLoader firmware itself!

This option is usually used when replacing the BootLoader with a new version, or when installing a firmware directly at the CPU reset address without using BootLoader firmware.


33


Loading Firmware

CPU Memory Page

•

Destination Memory Page

: Set the destination 1 Mbyte CPU memory page for HEX file. This term should not be confused with the CPU scrollable window for memory paging. Page 1 represents the memory range 00000H-FFFFFH and page 2 represents the memory range 100000H-1FFFFFH.

Due to Am186 ER, the CPU cannot access over 1 MB, this paging mechanism provides support for usage on the OptiScale board of bigger CPU Flash memory than 1 MB.

•

Boot Sector Protection

: If checked, avoids erasing and data downloading into boot sector. To protect the

Bootloader program against accidental overwriting, this option is always set automatically when the program is started and after every loading process.

•

Send Configure Device Command

: If checked, this sends a configuration command to the firmware before loading a HEX file. This option is useful if the default settings of the firmware are different from those of the current hardware board.

NOTE:

Usually, the Loading Settings are: Only involved sectors, Boot Sector Protection, and Send

Configure Device Command.

Convert BIN File in Intel HEX File Format

This option is very useful for converting FPGA code binary files, but can be used for any kind of binary data.

The PC Loader generates a new file in Intel HEX format with the same name as the BIN file, but with the extension HEX. To use this option, choose Convert BIN to HEX from the Tools menu and fill in the fields in the dialog box illustrated in

Figure 10

. This option is not required for the OptiScale normal operation.

The OptiScale Serial Control Panel allows the user to send individual commands to an OptiScale box. It also provides the capability to run script files that the user creates.

To create a script file, the user has to enter RS232 commands and scripting commands in a Notepad file. There are five scripting commands that can be used: DM, DS, LOOP/LEND, and HALT. The DM command delays the command execution in tens of milliseconds; DS delays the command execution in seconds; LOOP executes a group of commands (bounded by the LEND) command n times. When n is set to 0, the loop becomes endless; the HALT command pauses execution and waits for the user response.

The following is a list of script commands that can be used:

‘;’ — the semicolon indicates a comment

DM n — delay in tens of milliseconds

DS n — delay in seconds


35


RS232/422/485 Protocols

LOOP n — executes the instructions bounded by the LOOP in LEND n time

LEND — see LOOP n

HALT message — pauses execution and displays a message

Troubleshooting

Troubleshooting Guide

Before consulting Silicon Optix Technical Support for OptiScale, perform the following simple checks listed in

Table 38

.

Problem

Table 38: Troubleshooting Guide

Probable Cause Solution

No power (no illumination of LCD screen or front panel buttons)

Unit not plugged into main power

Ensure that the OptiScale power plug is connected to a live power outlet.

Power switch set to

OFF

Unit is in Standby mode

Ensure that the main power switch on the back of the unit is set to the

ON position.

Press the ONStandby button on the front of the unit. The front panel buttons should become illuminated.

Ensure that the input source is operational and connected to the

OptiScale unit

No picture output

No input source

Ensure that the input source is selected in the Input signals menu of the

OptiScale OSD. The selected input source should be highlighted gray.

If you're using a PC laptop, press the function key that lets you display on an external monitor. This key is often labeled with an icon, however, it may also be labeled CRT/LCD. You may have to hold down a

Function key while pressing it. Check your laptop's manual or online help for details.

Depending upon your computer's video card, you might need to use the

Display utility in the Control Panel to make sure that both the LCD screen and external monitor port are enabled. See your computer's documentation or online help for details.

Troubleshooting

Problem



Color of the output image is incorrect

The projected image is upside down or a reversed image is displayed

Incorrect Y Cb and Cr inputs

If the input video signal is in a component format, ensure that the Y Cb and Cr inputs are properly connected.

Incorrect color temperature and gamma settings

Incorrect color and tint settings

Projector image flip enabled

Check that the color temperature and gamma settings in the menu are correct for the input image.

Picture

Check that the color and tint in the

Picture

menu are correct for the input image.

OptiScale needs to be reset

If none of the above solutions correct the image, perform a factory reset on the OptiScale unit from the main OSD menu.

Check the projector to ensure that image flip is not enabled.

Front Tabletop option is not selected.

From the OptiScale OSD, select the

Geometry

menu, and then select the

Projection

submenu. Ensure that the

Front Tabletop

option is selected.

The bottom/top or left/right portions of the projected image are cut off. The entire image is not displayed.

Projector image position has been adjusted

Horizontal and vertical picture position are not set to zero

Check the projector to ensure that image position has not been adjusted.

From the OptiScale OSD, select the

Picture

menu, and then select the

Position

submenu. Ensure that the H and V sliders are set to zero.

The image is too small, too large, or compressed.

Wrong aspect ratio selected

Select a different aspect ratio by pressing the

Aspect Ratio

button on the remote control.

Wrong image position settings in the Picture menu

Make sure the image position settings are correct on the

Picture

menu.

The image appears blurry or soft

Computer resolution setting incorrect

There may be dirt or smears on the projector lens

Projector focused incorrectly

Picture sharpness setting incorrect

If you're using a computer, make sure its resolution setting is correct.

Clean the projector lens.

Adjust the focus of the projector.

Adjust the

Sharpness

setting in the OptiScale OSD

Picture

submenu.

Wrong SDTV deinterlacing setting

If the input is connected to an SDTV interlaced source, try selecting a different de-interlacing option in the OptiScale OSD

SDTV Deinterlacing

submenu. The recommended setting is

Auto

Anamorphic Scaling

Refers to the use of 16x9 aspect ratio pictures in a 4x3 system. For example, anamorphic supplementary lenses are used to change the proportions of an image to 16x9 on the surface of a 4x3 sensor by either extending the horizontal axis or compressing the vertical axis. Signals from 16x9 cameras and telecines produce an

anamorphic

signal which is electrically the same as with 4x3 images but will appear horizontally squashed if displayed at 4x3.

De-Interlacing

The blending of two video fields to form one progressive frame. This process avoids interlacing artifacts. See also

The alternative way of carrying 16x9 pictures within

4x3 systems is letterbox. Letterbox has the advantage of showing the correct 16:9 aspect ratio on 4:3 displays, the vertical resolution is less than 16:9 anamorphic.

Interlaced Display

In basic terms, a video can be thought of as being made up of numerous snapshots, called

frames

. The

frame rate

, or the number of frames displayed each second, is 29.97 in the United States and other NTSCbased countries. For the sake of simplicity, we can round this number to 30 frames per second (fps). In many European countries, PAL and SECAM video systems display exactly 25 fps. The following explanation is based upon 30 fps, but you can replace the number 30 with 25 for PAL/SECAM video and the same principles hold true.



55


Glossary

Television, however, does not deal with video in terms of frames. Instead, it displays a video using half-frames, called

fields

. Each frame contains exactly two fields. One field is made up of the odd horizontal lines in a frame. This is called the

odd field

or the

top field

since it contains the top line of the image. The other field is made up of the even horizontal lines in a frame. This is called the

even field

or

bottom field

. Since there are two fields in every frame, television actually updates the display at

60 fields per second (or 50 fields per second for

PAL/SECAM video). Each field is displayed 1/60 th

of a second after the preceding field (or 1/50 th

of a second for PAL/SECAM video).

Computer monitors and television screens do not display video in the same fashion. A computer monitor updates the image only once for each frame of video. Because of this, both fields that make up a video frame are shown simultaneously. Thus, a computer monitor displays video at 30 fps. This is called a progressive scan display.

The NTSC standard has a fixed vertical resolution of

525 horizontal lines stacked on top of each other, with varying amounts of lines making up the horizontal resolution, depending on the electronics and formats involved. There are 59.94 fields displayed per second. A field is a set of even lines, or odd lines. The odd and even fields are displayed sequentially, thus interlacing the full frame. One full frame, therefore, is made of two interlaced fields, and is displayed about every 1/30 of a second.

OptiScale

displays the selected input, input frame rate, output resolution, and output frame rate.

A television, on the other hand, updates each field of a video frame separately. Because of this, the television must update its display twice to show a complete frame. It first updates the odd field, and

1/60 th

of a second later it updates the even field. It continues to alternate between the odd and lines 60 times each second. Thus, a television displays video at 60 fields per second. This is called an interlaced display.

Pan

The movement of a camera. Horizontal pan is movement in a horizontal plane (azimuth); vertical pan is movement in a vertical plane (pitch).

common ground, which is relatively cheap, easy to arrange but susceptible to interference - hence the distance limitation.

PC Loader

Silicon Optix’ proprietary software used to load

OptiScale firmware.

The OptiScale RS232/422/485 interface lets you control the OptiScale box. The interface channel is

RS232C with 57600 baud, 8 bits data, 1 stop bit and no parity bit.

Plasma Display

A flat-panel, non-CRT video display device. The basic idea of a plasma display is the illumination of tiny colored

fluorescent lights

to form an image.

Each pixel is made up of three fluorescent lights - a red light, a green light and a blue light. Just like a

CRT television, the plasma display varies the intensities of the different lights to produce a full range of colors.

RS422/485 Interface

Not to be confused with 4:2:2 sampling or 422P

MPEG, this is a standard for serial data communications defined by EIA Standard RS422. It uses current-loop, balanced signalling with a twisted pair of conductors per channel, two pairs for bidirectional operation. It is more costly than RS232 but has a high level of immunity to interference and can operate over reasonably long distances - up to

300m/1000 ft.

Resampling

This function establishes the raw intensity for each output pixel based upon its relative position on the input space. Restated, this is the amount of input intensity proportional to each output pixel based upon the relative position of the output pixels on the input space.

S-Video

S-Video is one of the high quality methods of transmitting a television signal from a device such as a Camcorder, VCR, or a game machine

(PSX/Saturn/SNES and so on). It separates the color information (Chrominance) from the brightness

(Luminance), which prevents nasty things like color bleeding and dot crawl, and helps increase clarity and sharpness.

RGB

Video standard - Acronym for

R

ed,

G

reen and

B

lue signals, the primary colors of television. By varying the intensity of each of these colors in a single pixel, the human eye can be fooled into seeing a wide range of colors. For example, a combination of red and green appears as yellow, even though no light with a yellow wavelength is emanating from the screen.

This works because the optical system integrates the photons striking a region on the retina, and the combined impulses from green and red sensitive cones are seen as yellow.

Scaling Parameter

A single numeric value, such as

zoom

,

window offset

.

See

Control Parameter

. The Input and Output resolution (width and height) are used to adapt to different physical video resolutions at input and output. The

zoom

and

window offset

(horizontal and vertical) effectively allow the linear scaling and displacement of the input image; these can be used to implement a zoom and pan function in a projection system, for instance.

Throw Ratio

Throw ratio is defined as the ratio of projection distance (throw distance) over projected image width. That is, the ratio of the distance from the screen divided by the horizontal width of the screen.

It can also be described as the zoom of the projector optics.
