Connecting the cRIO-905x to the Host Computer orNetwork Using EthernetComplete the following steps to connect the cRIO-905x to a host computer or Ethernetnetwork using the RJ-45 Gigabit Ethernet port 0. NI recommends using the RJ-45 GigabitEthernet port 0 for communication with deployed systems.Note If your controller has the RJ-45 Gigabit Ethernet port 1, you can configurethat port in Measurement & Automation Explorer (MAX) under the NetworkSettings tab.1. Power on the host computer or Ethernet hub.2. Connect the RJ-45 Gigabit Ethernet port 0 on the cRIO-905x to the host computer orEthernet hub using a standard Category 5 (CAT-5) or better shielded, twisted-pairEthernet cable.Notice To prevent data loss and to maintain the integrity of your Ethernetinstallation, do not use a cable longer than 100 m (328 ft).The cRIO-905x attempts to initiate a DHCP network connection the first time youconnect using Ethernet. The cRIO-905x connects to the network with a link-local IPaddress with the form 169.254.x.x if it is unable to initiate a DHCP connection.Finding the cRIO-905x on the Network (DHCP)Complete the following steps to find the cRIO-905x on a network using DHCP.1. Disable secondary network interfaces on the host computer, such as a wireless accesscard on a laptop.2. Ensure that any anti-virus and firewall software running on the host computer allowsconnections to the host computer.Note MAX uses UDP on port 44525. Refer to the documentation of yourfirewall software for information about configuring the firewall to allowcommunication 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 serialnumber, such as NI-cRIO-905x-1856AAA.Tip If you do not see the cRIO-905x under Remote Systems, use theTroubleshoot Remote System Discovery utility to walk throughtroubleshooting steps.Configuring Startup OptionsComplete the following steps to configure the cRIO-905x startup options in MAX.1. In MAX, expand your system under Remote Systems.2. Select the Startup Settings tab to configure the startup settings.4 | ni.com | NI cRIO-905x User Manual
