Personal488 User’s Manual, Rev. 3.0 II-197

Configuration of IEEE 488 Interfaces

Note: The Driver488/W31

supports only the

IEEE interface.

The following

Driver488/W31 figure

displays the configuration of:

An MP488 IEEE 488.2

interface in the upper screen

section, and a

WAVE

external

device in the lower screen

section.

For additional information on

using more than one

interface, refer to the final

topic “Multiple Interface

Management” in the Sub-

Chapter “Installation &

Configuration” of Chapter 8.

Once an interface is selected,

the fields and default entries

which display in the

configuration window depend on the device type specified. The configuration parameters of the IEEE

interface, shown in the figure, are as follows:

Configuration Parameters

•

Name: This field is a descriptive instrument name which is manually assigned by the user. This

must be a unique name. Typically, IEEE is used.

•

IEEE Bus Address: This is the setting for the IEEE bus address of the board. It will be checked

against all the instruments on the bus for conflicts. It must be a valid address from

•

DMA: A direct memory access (DMA)

channel can be specified for use by the I/O

interface card. If DMA is to be used, select

a channel as per the hardware setting. If no

DMA is to be used, select NONE. The

NB488 does not support DMA, therefore the

DMA field will not display if this device

type is used. Valid settings are displayed in

the table.

•

Interrupt: A hardware interrupt level

(IRQ) can be specified to improve the

efficiency of the I/O adapter control and

communication using Driver488/W31. For

DMA operation or any use of

OnEvent

and

Arm

functions, an interrupt level must be

selected. Boards may share the same

interrupt level. If no interrupt level is to be

used, select NONE. Valid interrupt levels

depend on the type of interface. Possible settings are shown in the table.

•

SysController: This field determines whether or not the IEEE 488 interface card is to be the

System Controller. The System Controller has ultimate control of the IEEE 488 bus, and the

ability of asserting the Interface Clear (

IFC

) and Remote Enable (

REN

) signals. Each IEEE 488

bus can have only one System Controller. If the board is a Peripheral, it may still take control of
