inputs and the output are galvanically isolated.
Note! Alarm functionality is not yet implemented.
The front panel provides the following fixed interfaces for Nimbra 340:
•
Two ASI channels (A and B) for transport of video streams, each utilising
three 75 Ohm, BNC connectors for transmit, receiving and monitoring
purposes. In and Out connectors are accompanied with dedicated red/green
LED indicators, which reflect activity and status on the corresponding link.
MON (monitor) connector is accompanied with a push button and two green
LED indicators. The pushbutton allows to select whether the In or Out
stream should be routed to the monitor output, while the LED indicators
show the selection.
The front panel provides the following fixed interfaces for Nimbra 340-HD:
•
One HD-SDI channel for transport of video streams, utilising 75 Ohm BNC
connectors for transmit, receiving and monitoring purposes. In and Out
connectors are accompanied with dedicated red/green LED indicators,
which reflect activity and status on the corresponding link.
The front panel provides the following fixed interfaces for Nimbra 360:
•
Two Time Synchronization Interfaces (TSI) with 50 Ohm BNC physical
connectors
•
Trunk interfaces – delivered by default without SFPs, can be equipped with
OC-3/STM-1, OC-12/STM-4 or OC-48/STM-16 optical SFPs.
