Using this Blackmagic Design Mini Converter SDI Distribution is quite straightforward. First, connect your SDI source to the input of the converter. Then, connect your output devices to the available SDI outputs. Since it doesn't come with a power supply, make sure you use a compatible power source. When using it, avoid exposing it to extreme temperatures and humidity. For maintenance, keep it clean by using a soft, dry cloth to wipe the surface regularly. Also, check the connections from time to time to ensure a stable signal transmission.
