Using this Blackmagic Design Mini Converter for SDI signal distribution is quite easy. First, connect it to your SDI device. Since it doesn't have a power supply, you'll need to provide your own compatible one. When using it, make sure the connection is stable to avoid signal loss. For maintenance, keep it in a dry and clean place. Don't expose it to extreme temperatures or humidity. If there's any problem with the signal or connection, check the cables first. That's all you need to know to use and take care of this converter.
