Basic GPIB Concepts
Other GPIB features include:
• A concise and straight−forward command set
• Full serial poll capability, with SRQ
• Full local/remote capability including LOCAL LOCKOUT
This chapter is a guide to the syntax and usage of the various IEEE/488.2 common commands. It
also includes advanced programming tips for remote use with the 8033 device−dependent
commands, hardware diagrams, and other information relating to remote operation.
This chapter is divided into three parts. The first part contains information for getting started using
GPIB. It also contains the syntax for each 488.2 common command which is supported by the 8033.
The second part contains information on status reporting and advanced programming techniques.
The third part contains information on remote interface messages which are generally transparent to
the user.

Configuring the GPIB Controller

To use the MPS−8033 remotely, an IEEE 488 interface adapter is required in your host computer.
These adapters and support software are available from several manufacturers and can be installed
in most computers. Appendix C describes how to configure many of these interface adapters for
use with the 8033. This Chapter and Chapter 4 assume that you have a basic knowledge of the
IEEE 488 interface bus and how to use it for instrument control. You should also be familiar with
front panel operation of the MPS−8033. Manual (Local) operation of the 8033 is detailed in Chapter
2, Local Operation.

Changing Operation from Local to Remote

When the 8033 is in REMOTE all front panel controls are disabled except LOCAL/ADR. Press the
LOCAL/ADR switch to return the device to LOCAL control, thus, re−enabling the front panel.
If the Local Lockout state has been activated by the host computer even the LOCAL/ADR switch is
disabled. In this case, the host computer must deactivate the Local Lockout before front panel
control can be restored.
When the unit is in LOCAL mode, pressing the LOCAL/ADR switch causes the GPIB address to be
displayed for three seconds, e.g. "−01−".
Whenever the MPS−8033 is addressed by a system controller the REMOTE indicator illuminates and
the front panel is disabled from manual control. Press LOCAL/ADR to return to local (manual)
control.

Setting the GPIB Address

The talk and listen addresses on the 8033 are identical. When the unit is in LOCAL mode, pressing
the LOCAL/ADR switch causes the GPIB address to be displayed. The usable GPIB address range
is 0 to 30. Extended GPIB addressing is not implemented in the 8033. The GPIB address may be
changed by the following procedure.

Press and release the LOCAL/ADR switch. If the current GPIB address is not on the
display, press and release LOCAL/ADR again.
Press and hold the SET REFERENCE switch.
