RT procedure

Create a wireless ad-hoc network with two or more Academic RIO Devices

Set up one Academic RIO Device to serve as the ad-hoc network host, and then set up additional Devices to join the ad-hoc network. Note: The NI ELVIS III does not have the Web Interface for modifying these settings. Use NI Measurement and Automation Explorer (NI MAX) to modify these settings instead.

CAUTION: Consult your organization’s IT policies regarding ad-hoc wireless networks. These networks potentially interfere with the organization’s wireless infrastructure, therefore it is possible that ad-hoc wireless networks may not be permitted under your organization’s policy.

Procedure

Connect two (or more) Academic RIO Devices to the desktop:

  1. Connect both Devices by their USB cables to a desktop computer
  2. Browse to 172.22.11.2 with a supported browser (Firefox, Internet Explorer, or Safari) to start the Web-Based Monitoring and Configuration tool
  3. Open a new tab and browse to 172.22.11.10 to start the Web-Based Monitoring and Configuring tool on the second device
  4. Select the “Network Configuration” tab for each device
  5. Log in with the “admin” account on each device
  6. Decide which Device you wish to serve as the ad-hoc network host

On the host device:

  1. Choose “Wireless Mode” = “Create wireless network”
  2. Set the “ SSIDService Set Identifier, the name of a wireless network as it appears to other devices. ” field = name of the network as it will appear to other devices, e.g., “myRIO” or perhaps (“1myRIO” to ensure that it is at the top of the list later on)
  3. Select “Channel” = 1
  4. Set “Security” = “ WPA2Wi-Fi Protected Access 2, also called WPA or WPA2 Personal, a Wi-Fi security standard intended for consumer-grade wireless networks. Personal”
  5. Enter the “ WPA passphraseA string containing 8 to 63 printable ASCII characters (can include spaces and symbols) to authenticate clients on a consumer-grade wireless network. ” = 8 to 63 printable ASCII characters, i.e., can include spaces and symbols
  6. Set “Configure IPv4 address” = “ DHCPDynamic Host Configuration Protocol, an automatic mechanism to assign IP addresses to hosts on the network Only”
  7. Click “Save”
  8. Confirm that the Wi-Fi indicator LED is orange to designate this Device as the Host of the ad-hoc network

On the other device(s):

  1. Choose “Wireless Mode” = “Connect to wireless network”
  2. Click “Wireless Network” to see available networks
  3. Choose the SSID for the host device that you entered above
  4. Enter the passphrase
  5. Click “Save”
  6. Confirm that the Wi-Fi indicator LED is steady blue

Make note of the IP address of each Device as well as the gateway and subnet masks.
