communication and automatic program vectoring to service routines for Basic, C and Pascal programs.

For example, upon the occurrence of a specified event, such as

SRQ

TRIGGER

TALK

, or

ERROR

Driver488/DRV will automatically vector to your interrupt service routine.

Using Driver488/DRV, SCPI (Standard Command for Programmable Instruments) programmability

can be brought to Power488 I/O functions. SCPI is a language that defines common commands and

syntax for communication between controller and instruments. As such, it provides a consistent

programming environment for all SCPI-compatible equipment, simplifying programming and letting

you exchange instruments regardless of their make or type, without the need for extensive

reprogramming.

Driver488/DRV supports up to four IEEE 488 interfaces. There can be multiple external devices on

each interface up to the limits imposed by either electrical loading (14 devices), or with a product such

as Expander488, to the limits of the IEEE 488 addressing protocols.

Driver488/DRV supports the GP488B, AT488, GP488/MM, MP488, MP488CT and NB488 series of

IEEE 488.2 interface hardware. All interaction between the application and the driver takes place via

subroutine calls.

Before You Get Started

Prior to Driver488/DRV software installation, configure your interface board by setting the appropriate

jumpers and switches as detailed in “Section I: Hardware Guides.” Note the configuration settings

used, as they must match those used within the Driver488/DRV software installation.

Once the IEEE 488 interface hardware is installed, you are ready to proceed with the steps outlined

within this Sub-Chapter to install and configure the Driver488/DRV software. The Driver488/DRV

software disk(s) include the driver files themselves, installation tools, example programs, and various

additional utility programs. A file called

README.TXT

, if present, is a text file containing new material

that was not available when this manual went to press.
