interface as desired.

82350 GPIB Interface Card Configuration Parameters

SICL Interface

Name

Symbolic name that SICL uses to uniquely identify this GPIB interface. The

default Interface Name is gpib0. The SICL Interface Name must be a unique

string of alphanumeric characters, starting with a letter. Remember this value

and the Logical Unit number to properly address GPIB devices in your SICL

applications.

VISA Interface

Name

Symbolic name that VISA uses to uniquely identify this GPIB interface. The

default VISA Interface Name is GPIB0. The 82350 Interface Name for VISA must

begin with the string GPIB and have an integer appended to it, such as GPIB0,

GPIB1, GPIB2, etc. Remember this value to properly address GPIB devices in

your VISA applications.

Logical Unit

Number that SICL uses to uniquely identify this 82350 interface. The Logical Unit

number is an integer in the range of 0 - 10000. Remember this value and the

SICL Interface Name to properly address the GPIB interface in your SICL

applications.

Bus Address

address of this GPIB interface controller on the GPIB bus. It is usually 21 if the

GPIB interface is a System Controller or 20 if the GPIB interface is a non-System

Controller (see System Controller, following). These addresses are chosen by

convention but any address in the range 0 - 30, inclusive, may be used.

System

Controller

Determines if this interface controls which bus devices talk and which bus

devices listen. If several devices exist on a bus, be sure each has a unique GPIB

bus address and only one device is the System Controller (it is usually the device

installed in the computer). Each GPIB interface has its own independent bus.

Thus, each interface may be a System Controller as long as it is not chained

together with other GPIB interfaces. However, two or more System Controllers

on the same bus will cause the bus to be inoperative.
