Advanced operations

This section describes several operations that may simplify your use of the wireless terminal.

Selecting a data plan

The typical raw data volume when logging compressed .ghg eddy covariance files is about 1 MB per half hour, or about 1.5 GB of raw data in 30 days. See Table 6‑1 for more details.

Configure PC network communication

Note: This is only necessary when configuring the system. You'll do this when configuring the gateway the first time, or when connecting to it to change the configuration.

When connecting to a remote monitoring system you may need to configure your computer's network settings. The steps below describe how to do this with a Windows® 7 PC. The steps may differ for other computers and operating systems. Consult with your IT department and operating system documents for more information.

  1. Open the network window on your computer: Windows Start Button > Control Panel > View Network Status and Tasks > Connections.
  2. Click Change adapter settings.
  3. Double-click the Internet connection to bring up the Local Area Connection Status, then click Properties.
  4. Select Internet Protocol Version 4 (TCP/IPv4), then click Properties.
  5. If you need a dynamic IP address, select "Obtain an IP address automatically" and "Obtain DNS server address automatically," as shown on the left below. If you need a static IP address, select "Use the following IP address" and enter the IP address and Subnet mask as shown on the right below.
