INTRODUCTION
1.1 OVERVIEW
The KM4?8-ROM is an IEEE488 interface board that allows programs written on IBM
PC/XT/ATs, IBM I'S2 25/3Os,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 devices may be connected to the IEEE488 bus, including
instruments, printers, and other computers. The KM48-ROM comprises a board, software,
and documentation.
Figure l-l is a block diagram of the KM-488-ROM board.
Figure l-l. KM-4&WROh4Block Dlagram
The Kh4488-ROM design includes a Wait State Generator to adjust bus timing, allowing
performance within operating specifications of the GLIB controller chip on the fastest PCs.
This Board can also generate programmed interrupts on any of six interrupt request lines and
DMA transfers on Channels 1,2, and 3. Selection of messageterminators and timeouts is
modifiable to allow communication with GPIB devices using non-standard characters and
timeouts.
INTRODUCTION 1-1
The KM-488-ROM also features an 8-KB EEPROM (Electrically Erasable Programmable Read
Only Memory) containing firmware routines callable from a BASICA program. These
routines perform the IEEE-488transfer functions. KM-488ROM software libraries allow
accessto routines from programs in QuickBASIC, Microsoft C, and TURBO PASCAL.
Examples for each language are included.

INSTALLATION
2.1 GENERAL
Installation begins with procedures for unpacking and inspection followed by
recommendations and instructions for software. Next is a section on switch and jumper
settings. Board installation is the next step, followed by EEPROM configuration.
2.2 UNPACKING 81 INSPECTING
After removing the wrapped Board from its outer shipping carton, proceed as follows:
1. Before unwrapping the Board, place one hand firmly on a bare-metal portion of the
computer chassisto discharge static electricity from yourself and the Board (the computer
must be turned Off but grounded).
2. Carefully remove the Board fromits anti-static wrapping material. You may wish to save
the wrapping material for possible future use; if so, store it in a safe place.
3. Inspect the Board for signs of damage. If any damage is apparent, return the Board to the
factory.
4. Check the remaining contents of your package against the packing list to be sure your
order is complete. Report any missing items to the factory immediately.
5. When you are satisfied with preliminary inspection, you are ready to configure the Board.
Refer to the next section for configuration options.
2.3 SOFTWARE INSTALLATION
Backing Up The Distribution Software
As soon as possible, make a back-up copy of your Distribution Software. With one (or
more,as needed) formatted diskettes on hand, place your Distribution Sofhvare diskette in
your PC's A Drive and log to that drive by typing A: . Then, make your backup using the
DOS COPY or DISKCOPY command, as described in your DOS reference manual
(DISKCOPY is preferred becauseit copies diskette identification, too).
installing The Distribution Software
Install the KM-488-ROM Distribution Software on your computer's hard drive using the DOS
COPY command.
INSTALLATION 2-1
NOTE: If you are using BASICA and the factory default settings, you may run the KM-
4%ROM board without installing any software. Instead, proceed to Section 2.4.
To install the software:
1. Turn on your PC and its display. You should see the standard DOS-level prompt.
NOTE: If you install example programs written in multiple languages, you may want to
create a directory for each language. (This is the way the Distribution Software is
organized.)
2. The following instructions create a directory named KM488R. Type md \Rld488R
3. Change to the KM488Rdirectory by typing cd \KM488R
4. Placea KM-4&%ROM Diskette into the floppy drive (assumethis is Drive a:) and type
copy a:*.*
Repeat this step for each disk and/or subdirectory, until copying is complete.
Distribution Software Contents
Your Distribution Software contains the file FILESDOC , an ASCII text file readable with any
text editor or with the DO!? TYPE command. FlLES.DOC lists and briefly describes all files
in the Distribution Software.
The README.DOC File
To learn of last-minute changes,be sure to read the ASCII file READMEDOC
2.4 SWITCHES & JUMPERS
Factory Settings
The KMG%-ROM contains three DIP switches and two jumper banks (seeFigure 2-l). These
switches and jumpers are factory-configured to work with most PC configurations. Table 2-l
lists the factory selections.
Table 2-1. Factory Switch & Jumper Settlngs

I/O BaseAddress: 2b8h.
ROM BaseAddress: CCOOh

I/O Wait State: 1 Wait State;System Controller Enabled; EEPROM

Interrupt (IRQ) Level: Disabled.
DMA Level: Disabled.
2-2 KM-488~ROM USER GUIDE
For assistancewith setting the switches or the jumpers, run the INSTALL program. This
program illustrates the correct switch settings for your selections. To run the INSTALL
program, make sure you are in the appropriate directory and type INSTALL at the DOS
prompt. Then, follow program directions.
Figure 2-1. Switch and Jumper Locatlons
Switches
There are three DIP switch blocks on the KM48-ROM board, as follows: Wait State (Sl), I/O
BaseAddress (S2),and ROM BaseAddress 63). The switches are factory-set to work with
most PC configurations (seeTable 2-l for settings).
NOTE: If you are using BASICA and change the I/O BaseAddress DIP switch settings, be
sure to run the configuration program, CONFIG. SeeSection 2.7.
I/O Base Address Switch
Setting an I/O BaseAddress enables the KM-488-ROM to communicate with the PC. You set
an I/O BaseAddress for the Board by setting the seven positions of Switch S2 for the assigned
address. Setting a switch position to ON puts the corresponding address line at a logic 0
(low).
The KM-488-ROM requires a series of 8 I/O port addresses that begin with the I/O Base
Address. Therefore, be sure to select an I/O BaseAddress on an B-byte boundary that does
not conflict with other devices in your computer (refer to your PC manual for the I/O address
list to determine available spaces).
Figure 2-2 shows examples of I/O BaseAddress settings. Note that the factory-set Base
Address is 288 hex; the I/O ports occupy the address range 288 - 2Bf Hex.
INSTALLATION 2-3
FIgore 2-2. Examples of l/O Base Address SeftlngS
ROM Base Address Switch
This switch determines whether the ROM memory is to be enabled and, if so, where within
the first 1 MB of PC memory it is to be located. Enable the ROM if you are programming in
BASICA. The ROM BaseAddress Switch 63) is an B-position DIP switch.
Sevenof the S3 positions (1 - 7) to select the ROM BaseAddress. Position 8 enables/disables
the ROM. Setting a position at ON puts the corresponding address line to a logic 0.
To enable or disable the ROM, set 53 Position 8 as shown in Figure 2-3.
This position should be ON only if the KM-W-ROM is used with
BASICA software.
Flgure 2-3. Enabllng the ROM ~%B,EO %&LED
Some alternative ROM BaseAddress switch settings are shown in Figure 2-1. The default
BaseAddress is CC00 hex. Be sure to select an 8 KB address spacethat is within the first 1 MB
of PC memory and not occupied.
Flgure 2-4. ROM Base Address Selectlon
If you are unsure which address to assign to the EEPROM, use the MEMMAP program
provided with the KM-488-ROM. This program scansyour computer's memory and
determines what memory areasare available. To invoke the MEMMAI' program, switch to
the appropriate directory and type m . Choose an unoccupied address space.

I/O Waif States
The KM-B&ROM design includes a switch-selectable wait-state generator. A selectableWait
State insures optimum performance and reliable operation at the differing bus clocks found in
PCs. The default number of Wait States(11should be correct for most PCs. vowever, if,youf
data is garbled or your program crashes,you may need to adjust
the number of Wait States. Somegeneral guidelines are presented
in Table 2-2. Selectthe number of Wait Statesby setting Positions `03 911'1
1 and 2 (marked Wait State) on the DIP switch. You may program , w*,,STATE , w*l,STITFS
the KM468-ROM to generate one, two, three, or four Wait States iE~Yg~
during I/O. Note that the number of memory Wait Statesis
automatically set to a value which is one less than the I/O Wait
States. To select a number other than the default, set the switches
