USB 

The USB connector is as seen looking into the end of the cable mounted 
connector that can connect to a computer. 
DK3 and DK4 meters 
The 15 pin D connector is still used for any available audio format inputs, power 
and data connections. The SDI video format signal input is on an internally 
terminated 75 ohm BNC connector. The other BNC provides a buffered loop 
through of the incoming signal which may be in SMPTE format 424M, 259M or 292M - SD or HD SDI signals at 
data rates up to 2.97 Gbit/sec (3G).
