GPIB setup
The following provides information about GPIB standards, selecting the GPIB, setting the
primary address, and bus connections.
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 2750 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 2750 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.
Selecting GPIB and setting primary address
The Model 2750 is shipped from the factory with the GPIB selected and the primary
address set to 16. You can set the address to a value from 0 to 30, but do not assign the
same address to another device or to a controller that is on the same GPIB bus (controller
addresses are usually 0 or 21).
Perform the following steps to select the GPIB and set the primary address:
1.
Press the SHIFT key and then the GPIB key. The GPIB ON or GPIB OFF message
will be displayed.
2.
If the GPIB is already ON, press ENTER and proceed to step 3. Otherwise, press
the
key to place the cursor on OFF, press the
Δ
or
∇
key to display the ON
state, and then press ENTER.
NOTE
Enabling (ON) the GPIB disables (OFF) the RS-232 interface. Disabling the
GPIB enables the RS-232.
3.
To retain the presently displayed address (ADDR) value, press ENTER. Otherwise,
press the
key to place the cursor on the address value, use the
,
,
Δ
, and
∇
keys to display the desired address value, and then press ENTER.
