how to install Gefen HDMI & VGA to 3GSDI Scaler/Converter

1) Power down all equipment. Connect the Gefen EXT-HDVGA-3G-SC to a suitable power source using the included power supply. 2) Connect your HDMI or VGA source to the appropriate input on the scaler/converter. If you’re using HDMI, ensure the source’s audio is set to HDMI audio if you plan to embed HDMI audio into SDI. 3) Connect the SDI output from the Gefen device to your SDI-capable monitor, switcher, or recording device using a standard SDI cable. For best results over long distances, use high-quality SDI cables and verify cable lengths are within recommended specifications. 4) If you plan to embed analog audio, connect the analog L/R audio source to the device’s audio input as described in the user manual. 5) Power on the source device and the Gefen scaler/converter. If needed, adjust the output settings (resolution, aspect ratio, or color space) to match the capabilities of your SDI device, ensuring correct framing and synchronization. 6) Test the signal by viewing the SDI-connected display or monitoring device. If you encounter issues, verify input format compatibility, ensure the correct audio routing, and confirm that the SDI device is configured to receive the specified SDI family (3G-SDI or HD-SDI). 7) Save any preferred settings if the unit provides a memory option, and note your configuration for future use in similar deployments.
