5.1.2 914-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 approximated 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 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.
