Reference Manual
For routers other than the NV8140, Input backplane modules each have 9 connectors. Output
backplane modules each have 18 connectors. Expansion output backplane modules (only for
the NV8576-Plus) have 9 connectors and two 28-pin expansion ports.
For the NV8140, input backplanes for the NV8140 have 18 connectors.
Standard Cards
Standard input cards use all 9 connectors of the backplane modules. Standard output cards use
all 18 connectors of the backplane modules.
Disembedder and Embedder Cards
For routers other than the NV8140, hybrid disembedder (input) cards use 8 of the 9 connectors.
The 9th connector is not used. Hybrid embedder (output) cards use 16 of the 18 connectors. The
9th and 18th connectors are not used.
For the NV8140, hybrid disembedder (input) cards use 16 of their 18 connectors. The 9th and
18th connectors are not used.
Hybrid expansion embedder (output) cards use 8 of the 9 connectors.
There are no video ports or audio ports associated with the unused connectors.
MADI Cards
(MADI cards are also known as 3Gig/TDM cards.)
For routers other than the NV8140, hybrid MADI input cards use the first 8 connectors for video
input and use the 9th connector for MADI input (up to 64 channels). Hybrid MADI output cards
use connectors 1–8 and 10–17 for video output and use the 9th and 18th connectors for MADI
output (56 or 64 channels each).
These MADI input cards have 64 audio ports. The remaining 80 ports of the card’s port space are
unused.
For the NV8140, hybrid MADI input cards use connectors 1–8 and 10–17 for video input and use
the 9th and 18th connectors for MADI input (up to 64 channels each).
These MADI input cards have 128 audio ports. The remaining 160 ports of the card’s port space are
unused.
Hybrid MADI output cards use connectors 1–8 and 10–17 for video output and use the 9th and
18th connectors for MADI output (56 or 64 channels each).
Hybrid expansion MADI output cards use the first 8 connectors for video output and use the 9th
connector for MADI output (56 or 64 channels).
MADI output cards have 128 audio ports. The remaining 160 ports of the card’s port space are
unused.
Expansion Cabling for the NV8576-Plus
The expanded NV8576-Plus router comprises two interconnected router frames. The frames use
expansion cards and expansion backplane modules. Expansion output backplanes have 9 connec-
tors and two 28-pin expansion connectors. Cables connect the 2 router frames on the expansion
connectors.
