HP-IB Address
Each device on the
HP-IB
(
IEEE-488
) interface must have a unique
address. You can set the meter’s address to any value between 0 and 31.
The address is set to “22” when the meter is shipped from the factory.
The
HP-IB
address is displayed when you turn on the meter.
The HP-IB address can be set only from the front-panel.
•
The address is stored in non-volatile memory, and does not change
when power has been off or after a remote interface reset.
•
You can set the address to “31” which is the talk only mode. In this
mode, the meter can output readings directly to a printer without
being addressed by a bus controller. Address 31 is
not a valid address
if you are operating the multimeter from the
HP-IB
interface with a
bus controller.
•
If you select the
RS-232
interface and then set the
HP-IB
address to the
talk only address (31), the meter will send readings over the
RS-232
interface when in the local mode.
•
Your
HP-IB
bus controller has its own address. Be sure to avoid using
the bus controller’s address for any instrument on the interface bus.
Hewlett-Packard controllers generally use address “21”.
•
Front Panel operation: set the address under the
1: HP–IB ADDR
command in the I/O menu.
