GPIB Interface Reference
The GPIB connector on the rear panel connects your power supply to the
computer and other GPIB devices. Chapter 2 lists the cables that are available
from Agilent Technologies. A GPIB system can be connected together in any
configuration (star, linear, or both) as long as the following rules are observed:
Each device on the GPIB (IEEE-488) interface must have a unique address.
You can set the power supply’s address to any value between 0 and 30. The
address is set to ‘‘5’’ when the power supply is shipped from the factory. The
GPIB address is displayed at power-on.
You can set the GPIB address from the front panel only.
• The address is stored in non-volatile memory, and does not change when
power has been off or after a power-on reset (
*RST
command).
• 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.
Agilent Technologies GPIB interface cards generally use address ‘‘21’’.
• The total number of devices including the computer is no more than 15.
• The total length of all the cables used is no more than 2 meter times the
number of devices connected together, up to a maximum of 20 meters.
• Do not stack more than three connector blocks together on any GPIB
connector. Make sure that all connectors are fully seated and that the lock
screws are firmly finger tightened.
See page 46 for more information on configuring the power supply for remote
interface from the front panel.

IEEE-488 states that you should exercise caution if your individual cable
lengths exceed 4 meters.
