firewall. In this case, it is necessary to first connect to a VPN provided by
the cell service provider.

The Redirector
Sutron provides a “redirector” service that can be used to access a GPRSLink,
HSPALink, or CDMALink station that uses a SIM card provided by Sutron. The IP
addresses of these SIM cards are behind a firewall, and so need special steps to
be taken for access.
When obtaining one of these SIM cards from Sutron, you will also receive a user
name, password, and station name to use when setting up your station
connection in LinkComm. After entering your user name and password, you may
press the “Update Station Names” button to retrieve the list of stations that are
associated with your redirector account.

Dropped Connections
Please note that remote connections over cell networks, including those made
over Redirector, are not always the most reliable.
An internet TPC/IP connection to X-Link can get dropped. This can happen after
a timeout or due to a poor connection. If the connection is dropped, reconnect
by pressing the “Connect” button in the header, or by returning to the Stations
List view and pressing the “Connect” button
4.1.2.3.
Connecting via Wi-Fi
X-Link can provide a Wi-Fi hotspot that LinkComm can connect to. The Wi-Fi
feature is useful for connecting to X-Link with a mobile phone, tablet, or laptop.
X-Link models manufactured in 2013 or later feature Wi-Fi. These units are
identifiable by the button on the right side of the box.
