RADs from multiple Mongoose devices to a CobraNet device
The following graphics illustrate the aggregation of RAD channels from two Mongoose devices into a
single CobraNet Bundle. These graphics are more complex than the previous ones, so we’ll add more
explanation.
In this scenario, one Mongoose transmits two RAD channels to another Mongoose via CobraNet. The
second Mongoose combines two additional RAD channels (which are connected directly to the device)
with the two RAD channels arriving from the first Mongoose (via CobraNet). These four RAD channels
are then transmitted from the second Mongoose via a single CobraNet Bundle.
The high level signal flow view is self-explanatory. That is not the case with the detailed hardware view,
however. The following procedure explains the numbered steps you see in the illustration:
1. Mongoose A receives the signal from four RAD channels.
2. Mongoose A transmits all four channels via CobraNet Bundle 300 (Tx 300).
3. Mongoose B receives CobraNet Bundle 300 (Rx 300).
4. Mongoose B receives the signal from four RAD channels.
5. Mongoose B transmits all eight RAD channels via CobraNet Bundle 301 (Tx 301).
6. Another CobraNet device receives all eight RAD channels via CobraNet Bundle 301 (Rx 301).
