Section Three: Features
3.1 Enhanced Parallel Printer Interface (J10)
The enhanced parallel printer interface has a 25-pin female D-shell
connector, and is designed to connect to IBM and IBM compatible printers
via an IBM printer cable. This port is IBM PC/AT compatible. The parallel
port can be set via a jumper for the following options (refer to the silk-
screen printing on the actual board adjacent to jumper block J10).
IBM has defined 378 and 278 as the hexadecimal I/O port addresses for
LPT1, LPT2, and LPT3.
The interrupt for the parallel port is IRQ7 or IRQ5. These interrupts are set
using the appropriate jumper on J12 (IRQ7/IRQ5).

15
In addition to selectable addresses and interrupt requests, the IDE500 also
provides additional settings:
default (or standard) or
enhanced modes: EPP, ECP, IEEE 1284
You also have the option of specifying DMA Channel 1 or 3, or DMA
Channel.
The Parallel Port settings are defined as follows:
DEFAULT (standard). This setting defines the parallel port as a
standard uni-directional port for use with a printer.
EPP (enhanced parallel port). This setting defines the parallel port
as an 8-bit bi-directional port for use with hard drives, tape backup
systems, and other 8-bit bi-directional devices.
ECP (extended capabilities port). This settings defines the parallel
port as a high-performance 8-bit bi-directional port for use with
hard drives, tape backup systems, high-performance printers, and
CD-ROM drives. This mode also uses DMA to increase
performance and reduce system overhead.
IEEE 1284. This settings allows the parallel port to operate in any of
the modes described above (STANDARD, EPP, and ECP). NOTE: A
DMA channel is used in ECP and IEEE 1284 mode ONLY.
EPP and IEEE 1284 modes allow up to 8 devices to be daisy-chain
connected. See figure which follows:

NOTE: The use of hard disk drives, tape backup systems, CD-ROM
drives, etc. will require a device driver which is supplied by vendor of
that peripheral device. Refer to the manual which came with that device
for information pertaining to installation and use of a device driver.

3.2 Serial Device Interface (J6, J5)
NOTE: IBM has defined that IRQ4 is assigned to COM1 and IRQ3 is
assigned to COM2; these are needed for an interrupt driven device such
as a mouse. In general, serial ports cannot share a common interrupt,
nor can they share the same physical port. COM3 and COM4 are not
supported by IBM’s (and most clones’) system BIOS. IBM never
intended COM3 or COM4 to be initialized during boot-up. Your
application software may need to initialize these COM ports. Also note
that the cables attached to Serial A(J6) and Serial B (J5) are
interchangeable.
Serial Device Interface A(J6)
Located in the upper right-hand corner of the board, serial device
interface “A” has a 9-pin male D-shell connector, and is used to connect
to any asynchronous serial device using a standard EIA RS-232 interface.
Examples of such devices are serial printers, plotters, and modems.
Serial port “A” can be set via the J9 jumper for the options shown below:

Serial Device Interface B (J5)
Located in the upper right-hand corner of the board, this serial device
interface has a 25-pin male D-shell connector bracket assembly which
attaches via ribbon cable to the pin connector marked J5. This connector
can be used with the same types of devices as serial device interface “A”
described earlier in this subsection. Serial port “B” can be set via the J9
jumper for the options shown below. NOTE: If you do not need serial
port “B,” keep the logical port DISABLED.

3.3 Drive Interfaces
The J1 and J7 connectors on the IDE500 interface provide two 40-pin
connectors for IDE drive cables which can support one or two IDE hard
drives each. The J4 connector provides a 34-pin connector for a floppy
drive cable which can support one or two floppy drives.
The IDE500 comes with two 40-pin hard
drive interfaces referred to as IDE Aand IDE
B. IDE A(J1) should be used for attaching
higher-speed drives. With the included 40-pin
cable, you can connect one or two drives.
IDE B (J7) is intended for use with slower-
performing hard drives and other devices
such as CD-ROM and tape drives which are
compatible with the 40-pin IDE interface.
Note that any devices attached to the IDE B
interface require a special driver which
should be supplied by the manufacturer of
that device. When attaching drives to the IDE
A and IDE B, note the jumper settings for J8
as indicated on the board.
Cabling is keyed with a colored stripe (often red) for pin 1. Pin 1 is also
indicated on the board itself. J8 is used to enable/disable as well as
specify primary or secondary hard drive interfaces (IDE Aor IDE B, i.e.,
primary and secondary). J3 is used to enable/disable the floppy drive.

Section Four: Setting Jumpers
Before you install the IDE500, you may need to change the jumper settings
for your configuration. Always turn the system off before attempting the
reconfiguration, removal, or installation of the IDE500. You can change
configurations on the IDE500 simply by moving a jumper or combination
of jumpers from one pair of pins to another.
Place the board in front of you, component side up, with the bracket on
your right. The settings shown below are default settings for an IDE500
being installed in an IBM AT or compatible. In this sample installation, the
IDE500 is the first I/O support board being added to the system and is
configured as shown on the following pages.
Serial port Ais configured for COM1/IRQ4. Serial B is configured for
COM2/IRQ3. The Parallel port is configured for address 378 in standard
mode with no DMA selected set to IRQ7.
