6.1.2 914-VDX Composite Video Channels
The 914-VDX has two NTSC or PAL compatible composite video channels. The channel direction (input vs output)
is set up from the Model 914 Diagnostic GUI. Each channel uses approximately 250 Mb/s of available bandwidth
from the 914-HDE. No bandwidth is used if the video input is unplugged, or if that channel has been disabled via
the Diagnostic GUI. Latency through the Mux/Demux system is less than 500
s, not including fiber delays of 5
ns/m.
Coaxial shielding on the connectors is directly tied to ground, care must be taken to ensure a common ground to
all video equipment or isolation must be installed external to the 914-VDX. The video signal is AC coupled on the
PCBA.
The connector is a Mini SMB jack, Amphenol P/N 142146-75. Recommended mating plug is Cinch P/N 131-8403-
101, although other 75
Mini SMB plugs may be suitable. Cabling should be RG-179, 75
coaxial type. Video
latency through the mux/demux system is less than 25
s, not including fiber delays of 5 ns/m.
