❏ “PRIMARY & SECONDARY CobraNet ports” (page 22)
Incorrect—Primary and secondary can be used to build redundancy into systems. Under normal conditions, the
ACU16-C uses the PRIMARY port. However, if communication via that port fails, it will automatically switch to the
SECONDARY port and operation will continue uninterrupted.
Correct—Primary and secondary can be used to build redundancy into systems. Under normal conditions, the ACU16-
C uses the PRIMARY port. However, if system problems such as port malfunction or broken cable occur in the PRIMARY
port, it will automatically switch to the SECONDARY port. The audio signal will be momentarily interrupted, but the
duration of the interruption will depend on the performance and settings of the hub, and on the structure of the system.
❏ “Introduction” (page 25)
Incorrect—Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging between 512
CobraNet audio channels and 512 AES/EBU format inputs and outputs.
Correct—Up to eight NHB32-Cs can be used on a single CobraNet network, providing bridging a maximum (total
inputs and outputs) of 256 channels of CobraNet audio and AES/EBU audio.
❏ “CobraNet Primary & Secondary” (page 35)
Incorrect—In the first example, if a primary connection fails, the system automatically switches to secondary and
operation continues uninterrupted. However, if the switching hub fails, the entire system stops working. In the second
example, individual switching hubs are used for primary and secondary, so even if switching hub A fails, operation
continues on secondary via switching hub B.
Correct—In the first example, if a primary connection fails, the system automatically switches to secondary. However if
the switching hub fails, the entire system stops working. In the second example, individual switching hubs are used for
primary and secondary, so even if switching hub A fails, operation continues on secondary via switching hub B.
Be aware that with either connection, the time required in order to switch between primary and secondary will depend on
the performance and settings of the hub.
❏ “CobraNet Primary & Secondary, Ex. 2” (page 35)
In consideration of a case in which the primary connection fails, connect switching hub A and switching hub B.
