Connect your cRIO-904x to your host computer or the network using the Ethernet port.

Complete the following steps to connect the cRIO-904x to a host computer or Ethernet network using the RJ-45 Gigabit Ethernet port 0. NI recommends using the RJ-45 Gigabit Ethernet port 0 for communication with deployed systems.
Note You can configure the RJ-45 Gigabit Ethernet port 1 in Measurement & Automation Explorer (MAX) under the Network Settings tab.
  1. Power on the host computer or Ethernet hub.
  2. Connect the RJ-45 Gigabit Ethernet port 0 on the cRIO-904x to the host computer or Ethernet hub using a standard Category 5 (CAT-5) or better shielded, twisted-pair Ethernet cable.
    Notice To prevent data loss and to maintain the integrity of your Ethernet installation, do not use a cable longer than 100 m (328 ft).
    The cRIO-904x attempts to initiate a DHCP network connection the first time you connect using Ethernet. The cRIO-904x connects to the network with a link-local IP address with the form 169.254.x.x if it is unable to initiate a DHCP connection.

Finding the cRIO-904x on the Network (DHCP)

Find the cRIO-904x on a network using DHCP.

  1. Disable secondary network interfaces on the host computer, such as a wireless access card on a laptop.
  2. Ensure that any anti-virus and firewall software running on the host computer allows connections to the host computer.
    Note MAX uses UDP on port 44525. Refer to the documentation of your firewall software for information about configuring the firewall to allow communication through this port.
  3. Launch MAX on the host computer.
  4. Expand Remote Systems in the configuration tree and locate your system.
    Tip MAX lists the system under the model number followed by the serial number, such as NI-cRIO-904x-1856AAA.
    Tip If you do not see the cRIO-904x under Remote Systems:
    • Refer to Testing Your Controller.
    • Use the Troubleshoot Remote System Discovery utility to walk through troubleshooting steps.
