Remote Interface Configuration
This section gives information on configuring the remote interface. For
programming information, see Chapter 4, "Remote Interface Reference" starting
on page 129.
Remote Interface Selection
The meter is shipped with both a GPIB (IEEE-488) interface and an RS-232
interface. Only one interface can be enabled at a time. The GPIB interface is
selected when the meter is shipped from the factory.
The remote interface can be set only from the front-panel.
– The interface selection is stored in non-volatile memory, and does not change
when power has been off or after a remote interface reset.
– If you select the GPIB interface, you must select a unique address for the
meter. The GPIB address is displayed when you turn on the meter.
– If you select the RS-232 interface, you must set the baud rate and parity for
the meter. “RS-232” is displayed when you turn on the meter.
– If you select the RS-232 interface and then set the GPIB address to the talk
only address (31), the meter will send readings over the RS-232 interface
when in the local mode.
– There are certain restrictions to be aware of when you are selecting the remote
interface (see also “Programming Language Selection” on page 119). The only
programming language supported on RS-232 is SCPI.
– Front Panel operation: set the interface under the 2: INTERFACE command in
the I/O menu.
