Overview
The NV5256 is a machine control router
—
a successor to the NV3256. A machine control router
transmits control messages and responses between devices such as VTRs and edit stations.
Physically, the NV5256 has an 8RU frame that holds the following items:
• 16 I/O cards (RS-422/485 or RS-232)
• 16 RJ-45 backplanes.
• 2 expansion cards (for redundancy).
• 2 control cards (for redundancy).
• 2 power supplies (for redundancy).
A single NV5256 frame provides a 256×256 routing matrix. Two NV5256 frames can be connected
in tandem, using expansion cables, to provide a 512×512 matrix. A frame need not be fully popu-
lated. The NV5256 can be as minimal as a 16×16 router.
The following figures show the NV5256 features.
