Model 2520 User’s Manual
Remote Operations
10-3
The RS-232 interface is a serial interface. Programmable aspects of this interface include
the following (factory default settings are shown in parentheses):
•
Baud rate (9600)
•
Data bits (8)
•
Parity (none)
•
Terminator (CR)
•
Flow control (none)
RS-232 settings for baud rate, Parity, and data bits are accessible only from the front panel
while RS-232 is enabled.
An interface is selected and configured from the COMMUNICATIONS SETUP menu
accessed with the COMM key. For details on the programmable aspects of the interfaces,
see
“RS-232 interface operation,” page 10-16
NOTE
When changing interface selections, the Model 2520 performs a power-on reset.
To check and/or change options of the selected interface, you must re-enter the
COMM menu.
GPIB operation
This section contains information about GPIB standards, bus connections, and primary
address selection.
GPIB standards
The GPIB is the IEEE-488 instrumentation data bus with hardware and programming
standards originally adopted by the IEEE (Institute of Electrical and Electronic Engineers)
in 1975. The Model 2520 conforms to these standards:
•
IEEE-488.1-1987
•
IEEE-488.2-1992
The above standards define a syntax for sending data to and from instruments, how an
instrument interprets this data, what registers should exist to record the state of the instru-
ment, and a group of common commands. The Model 2520 also conforms to this standard:
•
SCPI 1996.0 (Standard Commands for Programmable Instruments)
This standard defines a command language protocol. It goes one step farther than
IEEE-488.2-1992 and defines a standard set of commands to control every programmable
aspect of an instrument.
