This manual introduces the basic operation methods, usage methods and precautions of the Doremi HDVI-20d product.
The HDVI-20d is a universal DVI‑D converter and switcher that accepts SDI, HD‑SDI, DVI‑D and DVI‑A inputs and outputs digital RGB DVI‑D signals. It automatically detects input scan rates and supports a wide range of video formats, including PAL, NTSC, 720p, 1080p, 1080i and 2K, and matches the resolution of connected DVI‑D monitors.
The manual covers installation, OSD and remote‑control functions, resolution and frequency settings, firmware upgrade, recommended LCD monitors, detailed specifications, warranty information and software licensing. It also provides troubleshooting steps and wiring diagrams for the RS422‑PC cable.
