serial digital video signal. The SDI output can be converted from analog composite video signal,
analog component video signal, or S-video signal by simple mode switch. And it supports the
input format of 576i 50 and 480i 60.
The LED lights on the Mini box indicate the status of input signal and power, so as to let the

left), others are invalid;
ii. When analog component signal is selected, the input interfaces from left are Y signal,
R-Y signal, and B-Y signal;
iii. When analog S video signal is selected, the input interfaces from left are Y, C, and the
third interface is invalid.
2.3 Left panel
DC IN：Power supply with 12V 1A.
PWR：Power indicator, the indicator shows green as the power is working normally.
IN：Status indicator of input signal, the indicator shows green when the input signal is locked with no
errors.
Note: The indicator only shows the status of the first input interface (from left);
SDI-OUT：BNC interface. It provides two identical output of digital video signal.
2.4 Front panel
