5.3.2. Connecting Remotely
LinkComm can also remotely connect to a XLink station if the optional cell modem is installed. To
do so, the Listening setting needs to be enabled.
Alternatively, to reduce power consumption, the system can be configured to check for messages
periodically. A message can be sent to the station asking it to temporarily turn on listening.
Please see the TELEMETRY section.
TCP/IP
If the IP address of a station is known, it can be connected to directly. It is up to cell service
provider to
Give a static IP address. This means that the IP address of station does not change over
time. Alternatively, you may send an SMS to the station asking what its current IP
address is.
Provide VPN access. It is not always possible to directly connect to the station over the
internet because it is protected by the cell service provider’s 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 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 username, password,
and station name to use when setting up your station connection in LinkComm. After entering
your username and password, you may press the “Update Station Names” button to retrieve the
list of stations that are associated with your redirector account.
5.3.3. Connecting via Wi-Fi
XLink can provide a Wi-Fi hotspot that LinkComm can connect to. The Wi-Fi feature is useful for
connecting to the station on-site with a mobile phone, tablet, or laptop.
XLink’s Wi-Fi hotspot is not connected to the internet.
To connect via Wi-Fi, follow this sequence:
Have the station turn on the Wi-Fi by pushing the wakeup button located on the front.
The station will blink the blue halo LED to acknowledge the button press.
Have your computer (Laptop, iPhone, or Android) connect to the Wi-Fi hotspot.
XLink will name its hotspot XL2_xxxx_aaaa, where xxxx is the station name, and aaaa is
a unique number.
Create a new station in LinkComm with “Connect type” set to “Station Wi-Fi”
(LinkComm may detect you are connected via Wi-Fi and set this type by default)
If you need to manually enter the IP address for XLink, it is 192.168.88.1:3001.
LinkComm is now connected to the station. It is possible to check status, change setup,
download log, and perform almost all other operations.
Once the LinkComm session is complete, make sure to disconnect from the Wi-
Fi hotspot.
