3.6.8 Point-to-Multipoint Serial-to-Serial Application
Example
The operation and data flow for this mode is very similar to
Point-to-Point serial-to-serial application, except that it uses multicast
addressing. The primary difference is that data presented at the Access
Point’s
COM
port will be packetized and sent via UDP to all of the
Remotes. Upon receiving the packet all of the Remotes strip the data out
of the UDP packet and send it out their
COM
port. Likewise, data pre-
sented at any of the Remotes’
COM
ports is packetized, sent to the
Access Point, stripped, and sent out the Access Point’s
COM
port (see
Figure 3-33 , Table 3-3 , Figure 3-34 , and Figure 3-35 on Page 76 .

1. Either COM port can be used, but they must be the same ones at both ends
of the link. Both COM ports can be used simultaneously for two independent
data channels.
