Point-to-Point Serial-to-Serial Application Example
Once you have configured the transceivers, they begin processing data
presented at the
COM
port is packetized and sent via UDP to the Remote. Upon receiving the
packet, the Remote strips the data out of the UDP packet and sends it out
its port. Likewise, data presented at the Remote's
COM
packetized, sent to the Access Point, stripped, and sent out the Access
Point's port. This configuration does not use multicast addressing.

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 port is packetized and sent using UDP to all of the
COM
Remotes. Upon receiving the packet, all of the Remotes strip the data
from the UDP packet and send it out their
presented at any of the Remotes'
