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.

Table 6‑1. Data generated by eddy covariance and soil systems.

Sensors in System	Files to Transfer	GB per Month1 Actual data volume will vary depending on the instrument configuration, the number of configuration files sent to the instruments, and other factors. The values given here assume 10 samples per second logging of the default variable set in an LI-7500RS.

Personal Computer	(optional) 192.168.128.200
LI-7200x or LI-7500x	192.168.128.201
LI-7700	192.168.128.202
Biomet System	192.168.128.203
LI-8100A	192.168.128.204

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. 
2. Double-click the Internet connection to bring up the Local Area Connection Status, then click Properties.
3. 
3. Select Internet Protocol Version 4 (TCP/IPv4), then click Properties.
4. 
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.
