INTRODUCTION
Gefen's DVI to HD-SDI Conversion Box is a universal DVI-D / SDI (HD and SD)
converter. It converts DVI-D to SDI (SD or HD digital YPbPr). It automatically detects
the input scan rate and supports a wide variety of video formats including PAL, NTSC,
720p, 1080p, 1080i.
The DVI to HD-SDI Conversion Box is an easy to use plug-and-play box that allows the
use of much lower priced DVI video sources for SD and HD pictures on SDI displays.
Set-up and operation are easy as they should be. But to ensure that the images look
good always, Gefen has focussed attention on the technical detail of the many facets of
the conversion process.
- Accurate spatial interpolation for clear sharp rendition of static images
- Advanced de-interlace processing for clear, accurate output of moving images
- Temporal processing for smoother frame rate conversion
- Small size, low power consumption
The SDI output of the DVI to HD-SDI Conversion Box makes it a full featured scan
converter that can take DVI-D and convert it to SD-SDI or HD-SDI based on an output
selection. So you can convert from NTSC to PAL, from PAL to NTSC, from NTSC to
1080i, from RGB to 1080i, etc….

RMT4-IR Installation
1. Remove battery cover from the back of the RMT4-IR remote.
2. Verify that dip switches 1 & 2 are in the up (ON) position.
3. Insert the battery, hold the battery so that you can see the positive side facing up. The
side that is not marked must be facing down.
4. Test the RMT4-IR remote by pressing ONLY one button at a time. The indicator light
on the remote will flash once each time you press a button. WARNING: Do not press
multiple buttons simultaneously and do NOT press buttons rapidly. These actions will
cause the remote to reset and steps 1-4 will have to be repeated.
Note: The RMT4-IR ships with two batteries. One battery is required for operation, the
second battery is complimentary.

Note: For a true RS422 connection, you can use an adapter made by KK Systems (Part
Number K422-99). This adapter connects to the RS232 port on the PC and provides
an RS422 connection on the other side. To connect the K422-99 to the DVI to HD-SDI
Conversion Box, use a standard RS422 cable (Male DB9 to Male DB9 pin to pin). A true
RS422 connection allows for a better connection and longer cables.
WIRING OF THE RS422-RS232 CABLE

The DVI to HD-SDI Conversion Box has an RS422 port that is used to upgrade the firm-
ware of the unit. You can make the cable using the wiring diagram shown at the end of
this document or purchase a cable form KK Systems.

HDVI20.exe, HDVI-20_Uploader.bat and the HDVI-20 bin file (version 1.30 or higher,
DO NOT USEANY EARLIER VERSION) in your DOS directory. The DOS directory
is the default directory when you launch the Command Prompt application under
Windows.
1. Connect the DVI to HD-SDI Conversion Box RS422-PC cable to a COM port on your
PC.
2. Connect the DVI to HD-SDI Conversion Box to a DVI monitor
3. Force the DVI to HD-SDI Conversion Box in flash mode by pressing and holding the
TV/Video on your infrared remote until the picture becomes red.
