All parameters can be changed, including the IP address, gateway, and subnet
mask (netmask) configured for the system. The next section provides
instructions for changing the IP address. Refer to Chapter 6 for more information
about changing the IP address and other parameters via the serial port.
The DNR-X-1G ships with preconfigured factory default IP addresses for NIC1
and NIC2 in nonvolatile memory (usually 192.168.100.2 for NIC1 and
192.168.100.102 for NIC2). These are static IP addresses; the system never
retrieves its IP address from a DHCP server.
This section describes when and how to change the default IP addresses.
You should change your IP address if you have multiple UEI chassis in your
application or if your application has network addressing guidelines you must
conform to.
Before connecting your DNR-X-1G to a general-purpose (company domain)
network, consider the following:
•
High sampling rate measurements consume a lot of the available
bandwidth.
•
Some samples may be significantly delayed or entirely dropped (lost)
due to network congestion, collisions or a slow switch.
•
Whether a system will be accessed by multiple parties on a LAN.
•
Whether multiple Cubes/RACKs/systems will operate (and interact) on
the same network.
Alternatively, if you plan to use the system for high-speed measurements where
high reliability is necessary – a direct connection between the host PC and the
1
DNR-X-1G NIC
is recommended.
Refer to "Network Configuration" on page 44 for more information.
