GPIB Interface
Each device on the GPIB (IEEE- 488) interface must have a unique address.
You can set the instrument’s address to any value between 0 and 30. 
The address is set to “9” when the instrument is shipped from the factory.
• Your computer’s GPIB interface card has its own address. Be sure to
avoid using the computer’s address for any instrument on the interface
bus.
• The GPIB address is stored in non- volatile memory, and does not
change when power has been off, after a Factory Reset (
*RST
command), or after an Instrument Preset (
SYSTem:PRESet command).
Front Panel Operation: Utility > REMOTE I/O > GPIB > GPIB ADDRESS
To set the GPIB address, turn the knob (or use the number keypad) 
to select the desired address.
Remote Interface Operation: SYSTem:COMMunicate:GPIB:ADDRess
LAN Interface
By default, DHCP is enabled on the instrument, which may enable network
communication over the LAN interface (10BaseT/100BaseTx) without
modifying default settings. However, you may need to change several LAN
configuration parameters, including:
• DHCP
• IP Address
• Auto- IP
• Subnet Mask
• Default Gateway
• Host Name
• DNS Server
• Domain Name
Front panel and remote interface instructions for setting these parameters
are provided in the following subsections.
