126 Getting Started GuideXSA MultiTouch InterfaceLAN Address ConfigurationLAN Address ConfigurationThe E6640A supports both dynamic and static assignment of its IP address,using ports LAN 1 and LAN 2 respectively.The LAN 1 port is designed for dynamic IP addressing, using the Dynamic HostConfiguration Protocol. If the your site network supports DHCP, the E6640Awill be assigned an IP address automatically when it is connected to the LAN.Once the address is assigned, it is listed, along with the computer name, underSystem > Show > System. The address or computer name can be used to findthe test set on the LAN. However, to see the System > Show > System screenand find this information, it is necessary either to connect a monitor to the frontpanel monitor port, or else to use the LAN 2 port to connect test set to a PCdirectly.Figure 4-18 Checking the LAN addressUsing the LAN 1 port to connect the test set directly to the public LAN ispotentially insecure, because the test set does not provide anti-virusprotection. Connecting the test set to the public LAN by way of a PC withantivirus protection is the preferred solution.The LAN 2 port is designed to use a private static IP address, 192.168.1.2(changing this address is possible but not recommended). This port can beused for direct connection to a PC.To find the test set on the LAN, you will need to know its IP address orcomputer name. If you cannot easily obtain a monitor view of System > Show> System, you can determine the computer name using the instrument serialnumber. The computer name is in the format K-E6640A-nnnnn, ending in thelast five digits of the serial number.
