Remote Interface Configuration
This section gives information on configuring the remote interface.
For additional information, see chapter 4, “Remote Interface Reference,”
starting on page 103.
HP-IB Address
Each device on the
HP-IB
(
IEEE-488
) interface must have a unique
address. You can set the multimeter’s address to any value between
0 and 31. The address is set to “
22 ” when the multimeter is shipped
from the factory. The
HP-IB
address is displayed at power-on.
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 multimeter can output readings directly to a printer
without being addressed by a bus controller (over either
HP-IB
or
RS-232
). For proper operation, make sure your printer is configured in
the listen always mode. 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 multimeter will send readings over the
RS-232
interface when in the local mode.
•
If you select the
RS-232
interface and then set the
HP-IB
address to
the talk only address (31), the multimeter 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”.
