EX7000 Series Preparation for Use 19
LInC-U Installation
To install LInC-U as a discovery tool for the EX7000’s embedded webpage, insert the
VTI Instruments Corp. Drivers and Product Manuals CD into the host PCs CD-ROM and, using
Windows Explorer, navigate to the <CD-ROM Drive>:\EX Platforms Requisites directory. Next,
run the VTI_LInC-U_setup.exe program. Once installation begins, simply follow the on-screen
instructions.
Java Installation
Java Runtime Environment (JRE) is required to access the SFP page of the EX7000. Prior to
installing JRE, ensure that all IE sessions have been closed. To install JRE, insert the
VTI Instruments Corp. Drivers and Product Manuals CD into the host PCs CD-ROM and, using
Windows Explorer, navigate to the <CD-ROM Drive>:\EX Platforms Requisites directory. Then
run the JRESetup.exe program. Once installation begins, simply follow the on-screen
instructions.
NETWORK CONFIGURATION
With its default network configuration, the EX7000 will attempt to locate a DHCP server. If one is
found, the IP address assigned by the DHCP server will be used. Otherwise, after a timeout of
20 seconds, the unit will attempt to obtain an IP address by using Auto IP.
NOTE At any time, the EX7000 can be returned to a known, default network configuration by using the
LCI (LAN Configuration Initialize) mechanism. See Reset Button for more information.
Auto IP is a mechanism for finding an unused IP address in the range 169.254.X.Y, where X is in
the range 1 through 254 and Y is in the range 0 through 255. The device will first attempt to obtain
the specific address 169.254.X.Y, where X and Y are the second-to-last and last octets (bytes) of
the device’s MAC address. However, X will be set to 1 if it is 0 in the MAC address, and to 254 if
it is 255 in the MAC address. This is in accordance with the Auto IP standard (RFC 3927). If this
address is already in use, the unit will attempt to obtain other IP addresses in a pseudorandom
fashion until it finds one that is available.
To illustrate the Auto IP mechanism, Table 2-1 lists the Auto IP default address for some example
MAC addresses.

TABLE 2-1: AUTO IP DEFAULT ADDRESS ASSIGNMENT
If a static IP address assignment is preferred, one can be optionally assigned via the embedded
web page interface. This is done by clicking the Network Configuration link, disabling DHCP
and Auto IP, enabling Static, and then assigning a static IP address, subnet mask, and gateway
address, and, optionally up to three DNS servers. For more information, see Network
Configuration in Section 4.
NETWORK TROUBLESHOOTING
If an error occurs when trying to discover the EX7000 (see Web Page Operation Introduction in
Section 4 for more information on discovery), it may be necessary to change the network settings
for the EX7000 and the host PC. By using the following methodology, most network-related
issues can be resolved:
