2.1 Safety Precautions
Always completely disconnect the power cord from
your board whenever you are working on it. Do not
make connections while the power is on, because a
sudden rush of power can damage sensitive
electronic components.
Always ground yourself to remove any static charge
before touching the board. Modern electronic
devices are very sensitive to static electric charges.
Use a grounding wrist strap at all times. Place all
electronic components on a static-dissipative
surface or in a static-shielded bag when they are not
in the chassis

2.6 Setting Jumpers
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. It
consists of two metal pins and a small metal clip (often protected by
a plastic cover) that slides over the pins to connect them. To “close”
a jumper you connect the pins with the clip.
To “open” a jumper you remove the clip. Sometimes a jumper will
have three pins, labeled 1, 2 and 3. In this case you would connect
either pins 1 and 2 or 2 and 3.

Open Closed Closed 2-3
A pair of needle-nose pliers may be helpful when working with
jumpers.
If you have any doubts about the best hardware configuration for
your application, contact your local distributor or sales representative
before you make any change.
Generally, you simply need a standard cable to make most
connections.

Pin Signal Pin Signal
HSB-460I offers 4 digital inputs and 4 digital outputs. The high and
low signals are received by the input connector to the computer.
Then the computer sends out the signals via the output connector.
You can attach one or two Integrated Device Electronics hard disk
drives to the HSB-460I internal controller. The HSB-460I IDE
controller uses a PCI local-bus interface. This advanced interface
supports faster data transfer.
Connecting the hard drive
Connecting drives is done in a daisy-chain fashion requires one of
two cables, depending on the drive size.
Wire number 1 on the cable is normally red or blue, and the other
wires are usually gray.
1. Connect one end of the cable to CN3, and make sure the red (or
blue) wire corresponds to pin 1 on the connector, which is
labeled on the board (on the right side).
2. Plug the other end of the cable to the IDE hard drive, with pin 1
on the hard drives. (Please see your hard drive’s documentation
for the documentation for the location of the connector.)
Connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either end of
the cable. If you install two drives, you will need to set one as the

master and the other as the slave by using jumpers on the drives. If
you install just one drive, set it as the master.
The IR connector can be configured to support wireless infrared
module. Install infrared module onto IR connector and enable
infrared function from BIOS setup. Make sure to have correct
orientation when you plug onto IR connector.

2.18 Floppy Connector (CN6)
With support of different types of floppy, you can simply adopt any
of the combinations of 5.25" (360 KB and 1.2 MB) and/or 3.5" (720
KB, 1.44 MB, and 2.88 MB) drives onto the mainboard.
A 34-pin daisy-chain drive connector cable is required for a
dual-drive system. On one end of the cable is a 34-pin flat-cable
connector. On the other end are two sets of floppy disk drive
connectors. Each set consists of a 34-pin flat-cable connector
(usually used for 3.5" drives) and a printed-circuit board connector
(usually used for 5.25" drives). Wire number 1 on the cable is
normally red or blue, and the other wires are usually gray.
Connecting the floppy drive
1. Plug the 34-pin flat-cable connector into CN6. Make sure that
the red or blue wire corresponds to pin 1 on the connector.
2. Attach the appropriate connector on the other end of the cable
to the floppy drive(s). You can use only one connector in the set.
The set on the end (after the twist in the cable) connects to A: drive.
The set in the middle connects to B: drive.
3. If you are connecting a 5.25" floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable
connector.
When connecting a 3.5" floppy drive, you may have trouble
printed on the circuit board indicating pin number 1. Also, the
connector on the floppy drive connector may have a slot. When the
slot is up, pin number 1 should be on the right.
Check the documentation that came with the drive for more
information.
