Models 2510 and 2510-AT User’s Manual Remote Operations 6-3
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)
An interface is selected and configured from the COMMUNICATION option of the Main
Menu (see “Main menu,” page 1-19). For details on the programmable aspects of the inter-
faces, see “Primary address,” page 6-6, and “RS-232 interface operation,” page 6-6.
NOTE When changing interface selections, the Model 2510 performs a power-on reset.
To check and/or change options of the selected interface, you must re-enter the
menu structure.
GPIB operation
This section contains information about GPIB standards, bus connections, and primary
address options. See Appendix C for more GPIB information.
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 2510 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 2510 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.
