External digital video output connectors
The digital video output connectors are standard, low profile, 75 Ohm impedance
BNC connectors, used to send HD/SD-SDI video signals. The connectors are
shown in the following image.
Their pin assignment is as follows:
For a clear signal, you should use a shorter cable as the data rate increases. To
prevent data loss, especially with higher definition signals, you will need high
quality components and a high-quality cable to compensate. You can use a
standard video cable to interface with these connectors.
