FCC Class B Compliance

NOTE: This equipment has been tested

and

found to comply with the limits for a Class B

Digital Device, pursuant to Part 15 of the FCC Rules. Theselimits are designed to provide

reasonable protection against harmful interference in a residential installation. This

equipment generates,uses,and can radiate radio frequency energy and, if not installed in

accordancewith the instructions, may causeharmful interference to radio communications.

However, there is no guarantee that interference will not occur in a particular installation. If

this equipment doesnot causeharmful interference to radio or television reception, which can

be determined by turning the equipment off and on, the user is encouraged to try to correct

the interferenceby one or more of the following measures:

Reorient or relocatethe receiving antenna.

Increasethe separation between theequipment and receiver.

Connect the equipment into

outlet on acircuit different from that to which the receiver

isconnected.

Consult the dealer or anexperiencedradio/tv technician for help.

NOTE:

The useof a non-shielded interfacecablewith the referenceddeviceis prohibited.

INTRODUCTION

1.1 OVERVIEW

The KM4?8-ROM is an IEEE488 interfaceboard that allows programs written on IBM

PC/XT/ATs, IBM I’S225/3Os,or compatibles

to communicate

with an IEEE488 bus. This

Board complies with the 1978IEEE488 standard and is thus compatible with other IEEE488

products. Up to fourteen other devicesmay beconnectedto the IEEE488 bus, including

instruments, printers, and other computers. The KM48-ROM

comprises a board,

software,

and documentation.

Figure l-l is ablock diagram of the KM-488-ROM board.

The Kh4488-ROM design includes a Wait StateGenerator to adjust bus timing, allowing

performance within operating specificationsof the GLIB controller chip on the fastestPCs.

This Board canalsogenerateprogrammed interrupts on any of sixinterrupt request lines and

DMA transferson Channels 1,2, and 3. Selectionof messageterminators and timeouts is

modifiable to allow communication with GPIBdevicesusing non-standard charactersand

timeouts.

The KM-488-ROM alsofeaturesan 8-KBEEPROM(Electrically ErasableProgrammable Read

Only Memory) containing firmware routines callable from aBASICA program. These

routines perform the IEEE-488transfer functions. KM-488ROM software libraries allow

accessto routines from programs in QuickBASIC, Microsoft C,and TURBO PASCAL.

Examplesfor eachlanguage are included.

1.4 HOW TO USE THIS MANUAL

This manual provides the information necessaryto install and program the KM-488-ROM.

The manual assumesyou are familiar with the language in which you aredeveloping your

application program; it alsoassumesyou are familiar with the IEEE-488protocol.

Chapter 2, Installation, details how to unpack, inspect,configure, and install the KM-488

ROM and how to copy the accompanying software. Additionally, Chapter 2describeshow to

install the KM48EROM software and to configure the EEPROMand reload EEPROM

software. There arealsonoteson using multiple boards in one system.

Chapter 3, Zntroductfanfothe

CaRableRoutines,

provides abrief functional description of each

KM488-ROM Interface Routine.

Chapter 4, Programmingthe

KM-488-ROM,

provides a detailed description of eachKM-488-

ROM InterfaceRoutine and how it iscalled from eachof the supported languages: BASICA,

QuickBASIC, C,and TURBO PASCAL.

Chapter 5, FactoryReturns, givesinstructions for returning the board to the factory.

The appendicescontain additional useful information. Appendix A contains an ASCII

EquivalenceChart. This giveshex and

decimal

equivalents for the ASCII 128Character set.

Appendix Bis an IEEE-488tutorial. Appendix C provides an explanation of the Device

Capability Identification codes. Appendix D provides across-referencechart of IEEE

Multiline Commands. Appendix Edescribeshow to usethe KM488-DD Printer Port Re-

director.
