To avoid fire and/or personal injury,

please observe these safety

and operating precautions:

Use the Proper Power Cord.

Use only the proper power cord specified for this

product and certified for the country of use.

Ground the Product.

This product is grounded through the grounding

conductor of the power cord. To avoid electric shock, the grounding conductor

must be connected to the earth ground. Before making connections to the input

and output of the product, make sure that the product is properly grounded.

Prevent Electrical Circuit Overloading.

The unit operates from a single-phase

power source with the neutral conductor at or near earth ground. The line

conductor is fused for over-current protection. A protective ground connection

through the grounding conductor in the power cord is essential for safe

operation. Ensure that the available AC line power is sufficient to meet the power

requirements of the unit without exceeding the rated load for the supply circuit

and its wiring.

Observe These Rack Mount Installation Precautions.

If the product is to be

rack mounted, make sure the following are observed:

* The unit operates correctly in ambient temperatures from 0 degrees C to

+50 degrees C. Leave space for cooling by ensuring standard side clearance for

rack mounting or 2 inches of side clearance for table top use. Also, ensure rear

clearance of approximately 3 inches so that cables are not damaged by sharp

bends.

*

Reduced air flow through and around the unit may have an adverse effect on

the operation and safety of the unit. Make sure that air flow is adequate to

ensure the ambient temperature does not rise above or below the specified

levels. When rack mounted, no equipment or other item is to be placed directly

on top of the unit as this will make the mounting of the unit unsafe and

unstable.

Installation Instructions

Follow these steps for

a simple and successful

Scan Do® HD Installation

Step 1:

Step 2:

Power Off both your computer and the Scan Do HD and disconnect

your DVI monitor from the DVI monitor port on your computer.

Using the supplied DVI input cable provided with the Scan Do HD,

connect one end to the DVI monitor port on your computer and the

other to the connector on the rear panel of the Scan Do HD marked

DVI-D Input.

Connect your DVI monitor, if you have one, to the Scan Do HD

connector labeled DVI-D Loop Through. Use the cable that is attached

to your monitor for this purpose.

Connect the AC line cord provided with the Scan Do HD to the AC

power connector. Plug the AC line cord to the wall outlet to provide

power.

Connect the Scan Do HD’s HD/SD-SDI output to your video equipment.

If desired, you may use all outputs simultaneously. (Refer to the next

section.)

Turn On the Scan Do HD first. Then, turn On the DVI monitor. Finally,

turn On your computer. The green input LED’s on the front panel

labeled Locked and Valid should illuminate, indicating the unit is

receiving a valid signal from the computer.

Step 3:

Step 4:

Step 5:

Step 6:

Available Outputs

HD/SD-SDI (2):

These outputs generate a SMPTE 292M or 259M compatible serial

digital signal. These outputs simultaneously produce the same signal and are

not capable of producing two different resolutions. The signal produced at these

outputs is determined by the settings for Line Count, Vert Rate, I/P, and Rate Div.

Note:

If one of the HD/SD-SDI Outputs is not used, it should be terminated at the

connector in 75 ohms to improve the eye pattern of the output that is used.

Fiber Optic:

This output is an optical version of the copper HD/SD-SDI outputs.

This optical output is in accordance with SMPTE 292M or 297M and uses an SC

optical connector. This output will support either single mode or multimode

(62.5u or 50u) fiber types. The factory default is off.

DVI Input Types Supported

DVI-D Loop Through:

This output is for a connection to a local DVI monitor.

It will show what is present on the DVI input. If the Scan Do HD is powered on, the

EDID information from the monitor connected to this output will be passed to the

computer's DVI port when the computer is booted. If no monitor is connected to

this output, then the Scan Do HD will provide EDID information to the computer.

Scan Do® HD will only support DVI single-link digital video signals. If a DVI-I source

is used, only the single-link digital signals will be processed.

Video Standard Selection

The output video standard and timing is established by a combination of settings

of the Line Count, Vert Rate, I/P, and Rate Div front panel settings.

The Scan Do HD will only allow valid SMPTE standards to be chosen. Please refer

to the section “Setting the Output Format” for instructions on selecting the video

standard from the front panel.

Operating the Scan Do® HD -

General Front Panel Operation

Setting the Output Format

The desired output format is established through a combination of four front

panel buttons:

Line Count ( LINE COUNT button ):

Determines the number of active horizontal lines in the image.

Vertical Rate ( VERT RATE button ):

Determines the base vertical refresh rate of the output. This is the number of

frames per second if the output is progressive and the number of fields per

second if the output is interlaced.

Rate Division ( RATE DIV button ):

Determines if the base Vert Rate is to be divided by 1.001 or not. For example, to

set the output vertical field rate to 59.94 the user would set the Vert Rate to "60",

the Rate Div to "1/1.001".

Interlaced/Progressive ( I/P Button ):

Determines if the output format is to be Interlaced or Progressive. Not all

options are available for all Line Counts and Vert Rates.

Note:

The allowed output format combinations of the above are specified in the

Specifications section of this manual.

Genlock Mode

Genlock Button Operation

Turn On/Off

GENLOCK

The GENLOCK button turns the genlock mode On and Off. When the genlock

mode is on, the unit looks at the genlock input and determines if a signal is

present. During this time the Searching LED will be lit. If a signal is present, the

unit determines if its format is compatible with the output format selected. If the

genlock input is valid, the Locked LED will illuminate.

The Scan Do HD will accept either NTSC/PAL composite video or HD tri-level sync.

The genlock vertical rate must match the output vertical rate in order to achieve

genlock but the horizontal rates do not have to match. Therefore, it is possible to

lock to an NTSC signal and produce a 1080i/59.94 output, for example.

The factory default setting is genlock mode off.

To genlock the Scan Do HD, connect a genlock signal to the Genlock Input

connector on the rear panel. There is a passive loop through from the genlock

input which is accessible on the Genlock Loop Through connector.

NOTE:

If the Genlock Loop Through is not used, it should be terminated at the

connector in 75 ohms.

The GENLOCK PHASING button, along with the DLY and ADV arrow buttons will

allow for phasing the output of the Scan Do HD relative to the genlock reference.

Horizontal, Vertical and Pixel Clock phasing can be adjusted.

Press the GENLOCK PHASING button to sequence through the three LEDs to select

the parameter to phase.

When the desired genlock phasing mode is enabled, the Left/DLY and Right/ADV

arrow buttons become the phasing delay and advance functions. Pressing the DLY

and ADV buttons simultaneously will reset the phasing mode to zero offset.

NOTE:

For NTSC and PAL output formats, set the Vertical Phasing to Zero Offset

before adjusting any phasing.
