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

Tip: When using Public mode, Sierra Wireless recommends
connecting the modem directly to the computer or other end device.
Using a hub or switch may prevent the PinPoint-E from updating the
IP address of the end device when an IP address is received from the
cellular network.
