CHAPTER 1 GENERAL INFORMATION 1
CHAPTER 1. GENERAL INFORMATION
1.1. Introduction to the Product
The PCL-848A/B MULTIFUNCTION IEEE-488 INTERFACE CARD is a valuable
addition to your PC that allows you to communicate with over 2000 products, made
by over 200 manufacturers, in over 14 countries. The IEEE-488-1978 standard that
this IEEE-488 card implements is the most widely used international standard for
information transfer between computer and electronic instruments.
There are numerous publications and articles that may be used in conjunction with
this manual to assist you to understand the interface standard. The IEEE reference
document may be ordered by writing to the IEEE Service Center, 445 Hoes Lane,
Piscataway, NJ 08854, USA.
The IEEE-488 interface card provides the hardware (electrical and mechanical) and
software required for you to interface your PC to the IEEE-488 bus. The software is
packaged in read-only-memory (firmware) and on a diskette to provide versatile and
easy-to-use IEEE-488 procedures for your Pascal language. Firmware cannot be
accidentally erased or overwritten and it is always available for use by application
programs. This manual provides a programming reference (Chapter 3.) and program-
ming techniques (Chapter 4. and 5.) to assist you in writing your own application
programs.
The key features of this interface card include:
*Operating in one of the two modes (switch selectable).
Mode A: Compatible with the PCL-748 IEEE-488 interface card and use the same
IEEE-488 function set.
Mode N:Software compatible with National Instrument PC-II and IBM-PC GPIB
adaptor and use the driver and software developed for them.
*Implementation of the entire IEEE-488 standard.
*Powerful and easy-to-use software command set. Fewer argu ments and simple
initialization.
*On-board RAMfor working space. No system memory space is needed for the
IEEE-488 interface operation.

2PCLS-848-P User's Manual
*Built-in 16 bit digital output port provides a convenient and economical solution for
signal switching and digital control applications. The D/O port is compatible with
the daughter boards: PCLD-785 Relay Output Board, PCLD-786 SSR & Relay
Driver Board and PCL-789 Amplifier & Multiplexer Board.
*The software can change the PC printer port to an IEEE-488 device. The PrtSc
(print screen) key, all print statements, word processing and spreadsheet programs
that use printer driver in BIOS can use IEEE-488 printers.
*High speed direct memory access (DMA) with the ability to handle 64K byte
arrays.
*Programmable system controller, active controller or device functions.
*All device functions, addresses, interrupt conditions, and parallel poll responses are
programmable.
*DIP switch selectable wait states (0/2/4/6 wait states) to ensure the compatibility to
very high speed PC’s.
*PCL-848A offers the connectors of the IEEE-488 standard while PCL-848B uses
the 25 pin D type connectors for the IEC-625 standard.
*Each device on the IEEE-488 bus can be assigned with its own terminator.
1.2. Description of the Documentation
Information in this manual is given at several levels of detail and is organized to allow
you work through the TUTORIAL, PROGRAMM ING REFERENCE and PRO-
GRAMMINGEXAMPLES chapters.
If you have no IEEE-488 experience, go to Chapter 9 after this chapter. The IEEE-488
TUTORLAL in Chapter 9 is designed to give you a thorough understanding of how
the IEEE-488 General Purpose Interface Bus (GP-IB) works. Topics in the TUTORI-
AL should be read in sequence if you have no IEEE-488 background and intend to
write application programs. With a solid understanding of the basic IEEE-488
concepts, followed by returning to the PROGRAMMING REFERENCE, and the
PROGRAMMINGEXAMPLES, you should be able to program almost any IEEE-
488 bus system without interface problems.

CHAPTER 1 GENERAL INFORMATION 3
If you are familiar with the basic concepts of the IEEE-488 bus you may want to
begin reading Chapter 3 PROGRAMMINGREFERENCE. This chapter describes the
statement syntax and techniques to use the IEEE-488 driver. Chapter 4 PROGRAM-
MINGEXAMPLES will show you how the procedures are used in typical applica-
tions and also provide you with useful program examples for your own applications.
If you want to know more details about this IEEE-488 interface card, please refer to
Chapter 5 ADVANCED PROGRAMMING TECHNIQUES. This chapter tells you
how to set DMA, how to modify transfer speed and how to use interrupts.
This manual is intended to be accurate and is organized to give you a quick reference
for programming ideas and the concepts of the IEEE-488 bus.
