Page 8: Applications
In most cases, using either P2P mode or Broadcast mode is suitable. But in multi-point cases, there may be better scenarios, which are described in the following sections: ICP DAS SST-900B User Manual v1.0, 2011/05 Page... - Page 9 Using either P2P mode or Broadcast mode is fine. 4.2.2 Peer-to-Peer - Using a 7188 module as a Bridge to connect to a 7000 series module Using either P2P mode or Broadcast mode is fine.

- Page 11 Using P2P mode is more suitable than Broadcast mode. Here is a suitable where setting the modules to P2P mode would be beneficial. Because both of SST-900B modules (2) and (3) are neither acting in the same roles as a slave, when they are communicating with SST-900B module (1), which is acting as the master, the SST-900B module (2) nor (3) will acquire unnecessary signals from each other.
- Page 12 So, in this situation, it would be better to set the modules to broadcast mode, in order to allow communication between two nodes. ICP DAS SST-900B User Manual v1.0, 2011/05 Page...
