PRO488 talks the established

IEEE control languages, so you

probably already know how to use

it! A good way to learn is

interactively from the PC keyboard

using the GPIBTALK program.

GPIBTALK is supplied ready to run

and with source code in each of 5

DOS languages. Menu driven, it

allows you to send IEEE commands,

transmit & receive data from your

bus devices and check the GPIB bus

status, all at the touch of a single

key. You get a good feel of the

power and ease of use of the

PRO488 command language in a

very short time. GPIBTALK is a fully

working skeleton program on

which to build your own custom

applications. Most IEEE equipment

includes worked examples that are

virtually word for word PRO488

commands!

The instant and simple PRO488

concept make Visual Basic and

PRO488 the intuitive system for

writing Windows applications

quickly and effectively.

The perfect partner for the PC

ELITE card is Professional 488, the

best PC-based IEEE software in the

world! PRO488 makes the PC ELITE

card an integral part of your PC,

allowing it to manage an IEEE bus

controlling up to 14 instruments. An

easy to use, enhanced industry

standard control language

addresses the IEEE devices and

provides complete instrumentation

control.

The heart of the PRO488 system

is the device driver that loads

automatically when your PC is

switched on, giving access to an

IEEE port in the same way as the

other resident ports LPT1 & COM1.

PRO488 makes full use of the

advanced features of your PC and

your IEEE bus instruments.

Data can be sent to the IEEE bus

devices in several ways. The

simplest is by writing to the

"IEEEDATA" file. PRO488

automatically addresses the devices

to listen and the PC outputs your

data.

Reading the "IEEEDATA" file

inputs data directly into your

variable from the IEEE bus device

using a complete handshake

sequence.

PRO488 is feature rich, with a

wide range of commands from the

lowest level, of individual line

control, right up through single

word commands that perform or

initiate whole sequences of bus

actions.

Complete worked examples,

source code, make files, icons,

everything you need in each of

Visual Basic, QuickC for Windows,

Visual C++, Borland C++ and Turbo

Pascal for Windows.

PRO488 is the ideal

environment for IEEE based data

acquisition. Mature and carefully

thought out, it implements a

superset of Hewlett Packard's HPIB

language.

The commands, and your

programs, read just like plain

English, so program development

and maintenance time is cut to an

absolute minimum. PRO488 runs

identically across the range of DOS

& Windows languages. The syntax,

parameters & returns of the

PRO488 system remain the same,

independent of the language you

are running. No extra language

driver or run time modules are

needed to implement a new

language. So you can use the ideal

IEEE system with the language of

your choice.
