Introduction to this Manual
About this Manual
This edition of the Personal488 User’s Manual supersedes all previous editions.
The material in this manual reflects the particular combinations of IEEE 488 I/O adapter and driver
software, and is comprised of four primary Sections: Hardware Guides, Software Guides, Command
References, and Troubleshooting, followed by two more Sections: Appendix and Index. The last two
pages contain a List of IEEE 488 Acronyms & Abbreviations and a List of ASCII Acronyms &
Abbreviations as additional references for this manual and for other related literature.
Before calling for technical assistance, check the Troubleshooting section for a possible solution to the
problem.
Since much of the hardware and software material in this manual is similar to material elsewhere in the
manual, make sure you view the material which corresponds to your specific hardware and software.
For example, do not read about Driver488/DRV when your application pertains to Driver488/W31
Information which may have changed since the time of printing will be found in a
disk, or in an addendum to the manual.
How to Use this Manual
Because this manual contains a large volume of information, a four-level table of contents system is
used in addition to a complete Detailed Table of Contents. In this four-level system, the General Table
of Contents at the front of this manual should be used primarily to locate the main Sections of the
manual, i.e., specific hardware guides and software guides. The first page of each Section contains a
second-level table, listing the Chapters with their page locations. Next, many of these Chapters
contain a third-level table, listing the Sub-Chapters or specific Topics with their page locations.
Finally, many of these Sub-Chapters contain a fourth-level table, listing the specific Topics with their
page locations. While this multi-level method is easy to use, experienced users may prefer the
traditional table of contents.
As mentioned above, this manual also includes an Index, so you can quickl y find the page(s) pertaining
to a specific topic.
Header Files & Command References
Since changes are taking place in Driver488/W95 and Driver488/WNT software as this publication
goes to press, please refer to your operating system header file for the latest available information
specific to your application.

IEEE 488.2 Interface Boards
The family of PC/IEEE 488 controllers includes the GP488B, the GP488/2, the AT488, the MP488,
the MP488CT, the GP488/MM and the NB488. All are IEEE 488.2 compatible and supported by
Driver488 software. The MP488 and MP488CT also provide digital I/O, and the MP488CT provides a
set of programmable counter/timers, all of which are fully supported by Driver488. Some features of
the interfaces are listed below:
•
GP488B interface board (for PC/XT/AT): Features five jumper-selectable interrupt lines. Three
8-bit jumper-selectable DMA channels are also available. The 8-bit DMA mode provides full
compatibility with programs written for GP488 series boards.
•

Driver488 Software Interface
Driver488 is the software interface between DOS or Windows and the IEEE 488 controller board.
Driver488 software includes the driver itself, an installation program, other utility programs, and
programming examples. Driver488 provides a full implementation of the IEEE 488.2 standard, plus
advanced capabilities such as high-speed DMA data transfers, interrupt vectoring on specified events,
automatic error detection, callable subroutines, and serial (COM) port support.
Driver488 monitors all IEEE 488 bus monitoring and control lines and generates an interrupt based on
SRQ
status and various other bus conditions. Driver488 software supports automatic program vectoring
to service routines for C, Pascal, and BASIC. On a specified event (
Controller, Trigger, Clear, Talk, Listen, Idle, ByteIn, ByteOut, Change
Driver488 can either call a specified application routine or simulate a light pen interrupt to signal that
the event has occurred.
Versions with HP-style character commands can be accessed by virtually any language that can
communicate with DOS files, and additionally provide standard DOS device driver interfaces which
permit communications with the IEEE 488 bus and/or connected devices in the same manner as LPT1,
COM1, etc. Versions with the Subroutine API offer higher performance and can be used with most
popular C, Pascal, and Basic languages. The Driver488 commands and bus protocol are very similar to
those used by the Hewlett-Packard HP-85 controller.

Note: The GP488B, as illustrated, has one DIP switch, two 12-pin headers and one 3-pin header,
labeled SW1, J3, J4, and J5 , r espectively. The DIP switch setting, along with the arrangement
of the jumpers on the headers, set the hardware configuration.
Default Settings
The figure indicates the GP488B default configuration. Notice that SW1 controls the wait state
generation, the I/O base address and interrupt response level, J4 sets the interrupt request level, J3
selects the DMA channel, and J5 selects the clock source.
I/O Base Address Selection
The I/O base address sets the addresses used by the computer to communicate with the IEEE 488
interface hardware on the board. The address is normally specified in hexadecimal and can be
22E1, 42E1
registers are then located at fixed offsets from the base address.
Most versions of Driver488 are capable of managing as many as four IEEE 488 interface boards. To
do so, the board configurations must be arranged to avoid conflict among themselves. No two boards
may have the same I/O addre ss, but they may, and usually should, have the same DMA channel and
interrupt level.
The factory default I/O base address is

Interrupt Selection
The GP488B interface board may be set to interrupt the PC on the occurrence of certain hardware
conditions. The level of the interrupt generated is set by J4. The GP488B adheres to the “AT-style”
interrupt sharing conventions. When an interrupt occurs, the interrupting device must be reset by
writing to I/O address
set by switches 1, 2, and 3 of SW1 which must be set to correspond to the J4 interrupt level setting.
Interrupt selection is illustrated in the following figure.
02FX
, where X is the interrupt level (from 0-7). This interrupt response level is
DMA Channel Selection
Direct Memory Access (DMA) is a high-speed method of transferring data from or to a peripheral, such
as a digitizing oscilloscope, to or from the PC’s memory. The PC has four DM A c hannels, but channel
0 is used for memory refresh and is not available for peripheral data transfer. Channel 2 is usually used
by the floppy disk controller, and is also unavailable. Channel 3 is often used by the hard disk
controller in PCs, XTs, and the PS/2 with the ISA bus, but is usually not used in ATs. So, depending
on your hardware, DMA channels 1 and possibly 3 are available. Under some rare conditions, it is
possible for high-speed transfers on DMA channel 1 to demand so much of the available bus bandwidth
that simultaneous access of a floppy controller will be starved for data due to the relative priorities of
the two channels. Configure the board according to which DMA channel, if any, is available.

Wait State Configuration
The GP488B is fast enough to be
compatible with virtually every
PC/XT/AT-compatible computer on the
market. Even if the computer is very fast,
the processor is normally slowed to 8MHz
or below when accessing the I/O channel.
If the I/O channel runs faster than 8 MHz,
it may be faster than the GP488B card. If
you suspect this is a problem, the computer
can be made to wait for the GP488B by
enabling wait states. Increasing the number
of wait states slows down access to the
GP488B card, but the overall performance
degradation is usually only a few percent.
Internal Clock Selection
The IEEE 488 bus interface circuitry requires a
master clock. This clock is normally connected to an
on-board 8 MHz clock oscillator. However, some
compatible IEEE 488 interface boards connect this
clock to the PC’s own clock signal. Using the PC
clock to drive the IEEE 488 bus clock is not
recommended because the PC clock frequency
depends on the model of computer. A standard PC
has a 4.77 MHz clock, while an AT might have a 6
MHz or 8 MHz clock. Other manufacturers’
computers may have almost any frequency clock. If
you are using a software package designed for an interface board (that derived its clock from the PC
clock) and you need to do the same to use GP488B with that particular software, the clock source can
be changed. However, the clock frequency must never be greater than 8 MHz, and clock frequency
must be correctly entered in the Driver488 software.
Board Installation
The IEEE 488 interface board(s) are installed into expansion slots inside the PC’s system unit. PC/ATcompatible computers have two types of expansion slots: 8-bit (with one card-edge receptacle), and 16bit (with two card-edge receptacles). Eight-bit boards, such as the IEEE 488 interface boards, may be
used in either type of slot, 8- or 16-bit. Some machines may have special 32-bit memory expansion
slots which should not be used for IEEE 488 interface boards.
Install each IEEE 488 interface board into the expansion slots as follows: Ensure the PC is turned off
and unplug the power cord. Remove the cover mounting screws from the rear of the PC system unit.
Remove the system unit cover by sliding it forward and tilting it upward.
Personal488 User’s Manual, Rev. 3.0 I-11
2. Personal488 (with GP488B) I. HARDWARE GUIDES
A rear panel opening is provided at the end of each expansion slot for mounting I/O connectors. If a
slot is unused, this opening is covered by a metal plate held in place with a screw. Remove this screw
and the cover plate from the desired expansion slot, saving the screw.
Insert the IEEE 488 interface board carefully into the expansion slot, fitting the IEEE 488 connector
through the rear panel opening, and inser ting its card edge into the motherboard card edge receptacle.
With the board firmly in place, fix its mounting bracket to the rear panel, using the screw removed from
the cover plate.
Slide the system unit cover back on, re-attaching it with the screws. Plug the power cord in and turn on
the PC. If all is well, the system should boot normally. If not, carefully check that none of the I/O
addresses conflict with any other devices or boards. If you are not sure, contact your PC’s dealer or
manufacturer.
