VTI’s LInC-U utility
The LInC-U Utility searches for all LAN-based VTI devices on the network and can be found on
the Distribution CD that shipped with the EX10xxA or may be downloaded from the
VTI Instruments corporate website. This utility leverages Apple’s Bonjour plug-in if it is installed
on the host PC, but, in its absence, uses the VXI-11 discovery protocol. This utility can also be used
to upgrade the EX10xxA’s driver and firmware. For more information on using the LInC-U utility,
please refer to its online Help file. For more information on discovering the EX10xxA, please refer
to
Web Page Operation in Section 4 .
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.

ONFIGURATION
By default, the EX10xxA/EX10xxA-51C/RX10xx/EX1044 will attempt to locate a DHCP server.
If one is found, the IP address assigned by the DHCP server will be assumed. Otherwise, after a
timeout of 20 seconds, the unit will attempt to obtain an IP address by using Auto IP.
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 - 254 and Y is in the range 0 - 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 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. 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.

SSIGNMENT
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
then assigning a static IP address. For more information, see Network Configuration in Section 4.
However, a much more convenient and recommended way to obtain the benefits of a static IP
address is to employ DHCP, but assign the instrument a reserved IP address in your company’s
DHCP server configuration. This reserved address, linked to the EX10xxA’s MAC address on the
DHCP server, would be assigned to the EX10xxA at power up initialization without having to
manually set it on the EX10xxA. The DHCP server configuration provides a centralized, controlled
database of assigned IP addresses, preventing accidental assignment of the same IP address to
multiple instruments. Consult your company’s Information Technology department for assistance.
