Summary
The M3 output card is functionally equivalent to the standard output card but is designed to
operate with M3 backplane modules. The M3 backplane module is one that has a 16-terminal
M3 connector.
The M3 connector is presently used to make connections from NV8500 hybrid routers to Kaleido
multi-viewers that have M3 connectors.
The M3 output card has 18 video channels, of which 2 use coax connectors.
At the KMX multi-viewer, the ports are numbered 1-16 on the M3 connector.
M3 Backplane Module
The M3 backplane module has one M3 connector and two coax connectors. The M3 connector
supports 16 of the video channels of the M3 card and the two coax connectors support the
other 2 channels.
When the backplane is installed in the lower output bays of an NV8576 frame, it is upside down
and its port ordering differs from when the backplane is installed in the upper bays (right side
up) of an NV8576 frame.
When the M3 backplane module is installed in an NV8140, NV8144, or an NV8280, it is consid-
ered right side up.
