Configuring instrument IP addresses

The objective of this section is to configure the network settings of the instruments, including the LI-7500A/RS/DS, LI-7200/RS, LI-7700, and LI-8100A. You'll need to do this for each instrument to enable communication through the network connection. If you are using a biomet system with a Sutron Datalogger, also see Setting the Sutron Datalogger IP address.

Power on the system

Note: Disconnect the RV50X Ethernet cable for this section.

Double check the power wiring and data cable connections. Flip both breakers to the ON position and wait a few minutes for everything to start up.

Figure 3‑1. Connecting to the system with a PC. At this point, the RV50X Ethernet cable is still unplugged but the system can be powered on.

Configuring the instrument network

Go through the following pages to configure IP addresses for each component. Skip any sections that don't apply to you until you get to Setting the LI-7500A/RS/DS or LI-7200/RS IP address.

Table 3‑1. Suggested IP addresses for instruments in an eddy covariance system.
Device IP Address
SmartFlux 2 System1 192.168.13.200
LI-7550 / SmartFlux 3 System 192.168.13.201
LI-7700 192.168.13.202
LI-8100A or LI-8250 192.168.13.203
Biomet System (Sutron Datalogger) 192.168.13.204
PhenoCam 192.168.13.205

Setting the LI-7700 IP address

If your system includes an LI-7700, start by configuring its IP address. If you do not have an LI-7700, skip to the next section.

  1. Launch the LI-7700 software and connect to the instrument.
  4. Click the Manual Controls button.
  6. Set the IP Address, Netmask, and Gateway.
    • IP Address: 192.168.13.202
    • Subnet Mask: Typically 255.255.255.0
    • Gateway: Set this to the IP address used to connect with the RV50X: (192.168.13.31)
  9. Reboot the LI-7700 after changing the network settings.

Setting the PhenoCam IP address

If your system includes a PhenoCam, set its IP address next.

  1. Be sure the camera is powered on and the Ethernet cable is connected to the switch.
  2. Launch the StarDot Tools application.
  3. Download it from http://www.stardot.com/downloads and install it on your Windows computer. Launch the app and it will present all of the PhenoCams that are on your network. Identify the one you want to configure and record its ID and IP address.
  4. Enter the IP Address into a web browser address bar.
  5. Upon connecting, the browser will display a recent image from the camera as well as some menu links.
  6. Click Config in the lower left of the page and log in when prompted.
    • User Name: admin
    • Password: admin
  8. Click the Network tab and configure the settings:
    1. Under IP Assignment, select Manual.
    2. Set the IP Address:
    • IP Address: 192.168.13.205
    • Subnet Mask: Typically it should be 255.255.255.0
    • Gateway: Set this to the IP address used to connect with the RV50X: (192.168.13.31)
  10. Reboot the PhenoCam after changing the network settings.

Setting the LI-8100A IP address

If your system includes an LI-8100A, set its IP address next.

  1. Connect a PC to the LI-8100A using the RS-232 cable.
  2. Launch the LI-8100A PC software and connect with the instrument.
  5. Click 8100 > Networking... and enter an IP Address, Netmask, and Gateway.
    • IP Address: 192.168.13.203
    • Subnet Mask: Typically it should be 255.255.255.0
    • Gateway: Set this to the IP address used to connect with the RV50X: (192.168.13.31)
  8. Restart the LI-8100A after changing the network configuration.
  9. If you are using a stand-alone RV50X, connect the LI-8100A network cable to the RV50X and keep the RS-232 cable in place for the remaining configuration. If you are using the LI-8100A in an eddy covariance station, connect the LI-8100A to the network switch.

Setting the LI-7500A/RS/DS or LI-7200/RS IP address

The LI-7500A/RS/DS or LI-7200/RS, in combination with the SmartFlux 2 or 3 System is the hub of the eddy covariance system.

  1. Launch the gas analyzer software.
  2. Select the gas analyzer and Connect to it.
  4. Stop data logging.
  5. Click the Stop button on the software dashboard.
  7. Configure the LI-7500A/RS/DS or LI-7200/RS for a Static IP Address: Click Settings > Network and enter the IP Address, Subnet Mask, and Default Gateway.
    • IP Address: 192.168.13.201
    • Subnet Mask: Typically 255.255.255.0
    • Default Gateway: Set this to the local IP address of the RV50X (192.168.13.31).
  11. Reboot the instrument after changing the network settings.

Multiple analyzers behind one gateway

The interface can store up to 20 connections. This is useful if you are unable to read the instrument IP address while attempting to connect or if you have more than one LI-7500A/RS or LI-7200/RS connected to the modem (differentiated by the port number). In this case, you'll need to assign unique ports to the gas analyzers. You can store the connection IP address and configuration to avoid recording this information elsewhere.

  • For the SmartFlux 2 System, check the Modem Connection box and enter the port (typically 5050) before storing the connection. The interface will store the connection information, enabling you to reconnect when the IP address is not retrievable.
  • For the SmartFlux 3 System, leave the box clear.

Identifying the SmartFlux 2 System MAC address

This step is required only if you want to use the SmartFlux 2 System as an NTP server or to enable two-way communication with the Biomet Data Acquisition System that is connected to a SmartFlux 2 System (to upload a new configuration file to a DAqM or DRM, for example). To find the SmartFlux 2 System MAC address, click the SmartFlux button and select the SmartFlux Connection tab. Copy the MAC Address or keep the window open so you can find it later when you'll enter it into the RV50X software.

Now you are ready to configure the RV50X. See Configuring the RV50X.
