connect to X-Link. This can be a considerable amount of data (several k-bytes).
Here again, you may choose to disable this feature to reduce data costs.
4.1.2.1.
Connecting via USB
LinkComm can connect directly to X-Link via a USB cable. Simply connect a USB
cable from your computer to X-Link.
USB drivers are included in the LinkComm download package. These drivers are
required to connect to X-Link over USB. Please see Section 2, Getting Started,
for more details on their installation.
Please be sure to follow the instructions in Section 2, “Getting Started”, to
download and run LinkComm, connect it to X-Link, and verify communications
before setting out to the field. Indeed, we recommend that station setup be
completed and tested at the office before deploying the station.
To connect via USB, set “Connect type” to “Serial”, and then set “COM port” to
the port assigned to X-Link by the operating system.
When X-Link is first connected to a USB port, Windows will create a virtual Com
port (e.g. COM5). Each time the cable is connected to a different USB connection,
a new port is created. The port assignment can be confirmed using Windows
Device Manager (Control Panel). If LinkComm does not list the assigned port,
please enter it manually.
4.1.2.2.
Connecting Remotely
LinkComm can also talk to a GPRSLink, HSPALink, and CDMALink over the
internet. To do so, GPRSLink, HSPALink, and CDMALink need to have the
Listening
setting 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 Message Check section on page
61 and Sending Messages to X-Link on page 57.
4.1.2.2.1.
TCP/IP
If the IP address of an HSPALink, GPRSLink, or CDMALink is known, it can be
connected to directly. It is up to cell service provider to
1.
Give a static IP address. This means that the IP address of X-Link does not
change over time. Alternatively, you may send an SMS to the X-Link
asking what its current IP address is.
2.
Provide VPN access. It is not always possible to directly connect to X-Link
over the internet because it is protected by the cell service provider’s
