5.3.2.
Connecting Remotely
LinkComm can also talk to a Stalink with the with the optional cell modem 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.
5.3.2.1.
TCP/IP
If the IP address of a Satlink 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 Satlink does not change over
time. Alternatively, you may send an SMS to the Satlink asking what its current IP
address is.
Provide VPN access. It is not always possible to directly connect to Satlink 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.
5.3.2.2.
The Redirector
Sutron provides a “redirector” service that can be used to access a Satlink 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.
5.3.3.
Connecting via Wi-Fi
Satlink can provide a Wi-Fi hotspot that LinkComm can connect to. The Wi-Fi feature is useful for
connecting to Satlink on-site with a mobile phone, tablet, or laptop.
Satlink’s Wi-Fi hotspot is not connected to the internet.
To connect to Satlink via Wi-Fi, follow this sequence:
Have Satlink turn on the Wi-Fi by pushing the wakeup button located on the front.
Satlink will blink the blue halo LED to acknowledge the button press.
Have your computer (Laptop, iPhone, or Android) connect to Satlink’s Wi-Fi hotspot.
Satlink will name its hotspot
SL3_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 to Satlink via Wi-Fi, and set this type by
default)
If you need to manually enter the IP address for Satlink, it is 192.168.88.1:3001.
LinkComm is now connected to Satlink. It is possible to check status, change setup,
download log, and perform almost all other operations.
