 DHCP – Identifies the status of the Dynamic Host Configuration Protocol

enabled (Yes), it automatically assigns an open IP Address to the instrument.
When DHCP is disabled (No), the network administrator must manually
assign the instrument an open IP Address. Use the Select button to highlight
the DHCP value, and use the Change or Arrow buttons to change the DHCP
status.
 Ethernet Address, Subnet Mask, and Gateway – Identifies the IP Address
used for remote communications via Ethernet. Questions about the
appropriate settings for these parameters should be directed to the network
administrator. For more information, see the Remote Communications
section (Chapter 5). Use the Select button to highlight the value’s left most
digit, use the Change or Arrow buttons to set the desired number, and use
the Select button to highlight the next digit to the right. Repeat until all twelve
digits are set.

NOTE: For the vast majority of user applications, the default rate of 921600
is the correct Baud Rate and should not be changed. If the USB Baud Rate
must be changed, use the Select button to highlight the USB Baud Rate
value and use the Change or Arrow buttons to change the USB Baud Rate.

recommended, and will disable the instrument from connecting to the
