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 EX7000’s MAC address on the
DHCP server, would be assigned to the EX7000-OEM at power up initialization without having to
manually set it on the EX7000. 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.
VXI-11 Device Discovery is also supported by the EX7000-OEM. This allows all EX7000-OEMs
on a local network to be found without knowledge of their MAC address or IP address with the
use of a broadcast message. Additionally, EX7000-OEMs provides MDSN (multicast domain
name system) support and may be discovered by software such as Bonjour

TIME CONFIGURATION
This entry page is used to change the time configuration of the EX7000OEM. By default, the
instrument has no notion of “wall-clock” or calendar time. The instrument has no battery-backed
clock or any other mechanism to retain time between reboots and power-cycles. By default, the
instrument’s time and date at power-up are midnight, January 1, 1970 (the beginning of the
“epoch”). The time and date can be manually specified on the Time Configuration page
(
Figure 4-6). Manual configuration will be necessary if the network environment is such that the
instrument cannot reach the Internet. Manual time entry is not affected by the Time Zone control
and does not require an instrument reboot to be activated. However, manually-specified time is
volatile, and, therefore, must be reentered upon an instrument reboot or power cycle. It is not,
however, affected by the Reset page.
