Data Communication
Note: The Raven XT forwards
messages to and from the
cellular network for only ONE
device per port. The Raven XT is
a one-to-one gateway and does
not have advanced routing
features required to do one-to-
many routing.

port, they will not be able to communicate to each other. Each port is
routed separately to the cellular network with one-to-one routing for
each.
