2 Description HDVI is a compact digital video interface that converts serial digital video (SDI and HDSDI) to DVI (digital RGB). It automatically detects the input scan rate and supports a wide variety of video formats including PAL, NTSC, 720p, 1080p and 1080i. HDVI can be connected to computer LCD monitors, HDTV Televisions with DVI input, video projectors and displays (Plasma, DLP, D-ILA etc.). It supports both DVI-HDTV Televisions (no scaling) and DVI-LCD monitors (automatic scaling).
3 HDVI-10 Operation On power up, the HDVI-10 will automatically detect the input format of the SDI video and will send a message to the monitor connected via DVI requesting its EDID parameters. The EDID parameters of the connected monitor will be used by the HDVI-10 to determine its output resolution. The HDVI-10 can operate in two modes. Auto Mode (default) and Pass Through Mode. In all output modes, the HDVI will always keep the aspect ratio of the input.
4 HDVI Supported Output Resolutions HDVI works with all DVI monitors that support any of the following resolutions: Automatic Scaling: 1024x768, 1280x720, 1280x768, 1280x800, 1280x1024. No Scaling: 1080p (1920x1080 @24/25/30), 1080i (1920x540 @48/50/60) and 720p (1280x720 @60). To save the output resolution to the HDVI-10 flash EPROM, press ENT,1,2,3 on your Sony infrared monitor. When you reboot the HDVI-10, it will restore the output mode from flash. The default output mode is Auto Mode.
7 RS422 Port The HDVI-10 has an RS422 port that can be used to view the current settings of the unit. To connect the RS422 port to a PC you need a special RS422-RS232 cable that can be purchased from Doremi by contacting support@doremilabs.com You can also make the cable using the wiring diagram shown at the end of this document.

Recommended LCD Monitors All LCD monitors that support the resolutions listed in this document would work properly with the HDVI-10.
HDVI Firmware Update Procedure To update the firmware on the HDVI you will need the following files: hdvi_set_flash_mode.exe, HDVI_flash.exe, HDVI_update.bat and the HDVI_096.bin firmware file. 9.1 Setup 1. Use only a PC running Windows 2000 or Windows XP. 2. All four files listed above should reside in the directory where the command prompt goes to by default. THIS IS VERY IMPORTANT. Open a Command Prompt Window and see what directory is listed and copy all four files into that same directory. 3.
