Making Network and Non-Network Connections

The host computer communicates with the remote system over a standard Ethernet connection. If the host computer is already configured on a network, you must configure your remote system on the same network. If neither machine is connected to a network, you must connect the two machines directly using a CAT-5 crossover cable or hub. You can use the direct connection to configure the remote system from the host computer system.

Note  If your target does not support automatic IP address assignment and you want to make a direct connection using a CAT-5 crossover cable, you must first disable DHCP on your host computer. Complete the following steps to disable DHCP: From the Windows Start menu, select the following, depending on your computer's operating system: Control Panel»Network and Internet»Network and Sharing Center»Manage network connections if you are using Windows Vista Control Panel»Network Connections if you are using Windows XP Settings»Control Panel»Network and Dial-up Connections if you are using Windows 2000 Right-click the network connection you want to configure, and then select Properties. On the General tab, click Internet Protocol (TCP/IP), and then select Properties. In Windows Vista, select Internet Protocol Version 4 (TCP/IPv4). Click Use the following IP address. Enter an IP address for your host computer.

For targets that do not automatically acquire their IP addresses from DHCP, both the host computer and the remote system must reside on the same subnet in order for you to configure the remote system with MAX.

You can develop and run LabVIEW Real-Time Module applications when the remote system is on a different subnet than that of the host computer. To run LabVIEW Real-Time applications on a remote system that resides on a different subnet, assign a static IP address to the controller that corresponds to the subnet where the remote system is located. Refer to Assigning an IP Address for more information about IP addresses.
