Inputs and Outputs
I/O Cards
These are the input and output card types for the NV8140
The expansion output cards all have two inter-frame connections, in addition to their output
connectors.
For signal reclocking rates, see
NV8500 series routers can transport DVB-ASI and similarly formats.
AES Async
AES async cards are standard cards, not hybrid.
AES async signals are AES pairs (normally stereo pairs). In NV8500 series routers, they do not
require an AES reference signal.
For instructions on making AES reference connections, see
The NV8140 does not support AES async.
Input
The AES async input card receives up to 9 balanced or unbalanced signals through local I/O
connectors: DIN 1.0/2.3, for unbalanced signals or WECO, for balanced signals. An incoming
signal can be distributed to any or all AES outputs.
Each input card has 9 AES receivers. The AES receiver distributes the signal to the motherboard.
The motherboard forwards the signal to the crosspoint cards for distribution to output cards.
The input card also sends its signals to a monitor selector for forwarding to the monitor card.
(See
Output
The AES async output card receives 18 signals from the crosspoint card (via the motherboard).
The card contains 18 transmitters. Each transmitter creates 2 copies of the outgoing signal,
feeding one copy to a connector and one copy to a monitor selector. The monitor selector sends
