SlimSCSI 1480 User’s Guide
Note:
The CardBus specification differs from the standard
PC Card (PCMCIA) specification. As a result, CardBus
adapters like the SlimSCSI 1480 will not operate in, and can-
not be inserted in, a standard PC Card slot.
Installing the SlimSCSI 1480
Follow these steps to install the SlimSCSI 1480 and connect your
SCSI devices to it:
1
Remove the SlimSCSI 1480 from its packaging.
2
Determine which of the two 50-pin cables you will use to con-
nect the SlimSCSI 1480 to your first (or only) SCSI device. To
do this, see which cable connector (high-density or low-den-
sity) fits the SCSI connector on the back of the device.
Note:
If your SCSI device has a DB25 (25-pin) connec-
tor, you can order a free DB25 cable from Adaptec by
sending in the card included in this User’s Guide.
3
Connect the SlimSCSI cable to the SlimSCSI 1480, as shown
below:

4
Plug the other end of the cable into the first (or only) SCSI
device, as shown below. Make sure the SCSI device is not
powered.
5
(Optional) Connect up to two additional UltraSCSI devices by
daisy-chaining them to the first device, as shown below:
6
Be sure that each SCSI device has a unique SCSI ID ranging
from 0 to 6. If any two devices have the same ID, change the
SCSI ID of one device. This is usually done by changing a
switch on the back of the device. (For more information, see
SCSI IDs on page 10.)

SlimSCSI 1480 User’s Guide
The diagram below shows a typical SCSI device with a select-
able SCSI ID switch:
7
Terminate the last (or only) SCSI device connected to the
SlimSCSI 1480. Read the device documentation if you are not
sure how to terminate the device, or refer to Terminating the
SCSI Bus on page 11.
8
Be sure that at least one external SCSI device provides SCSI
bus termination power or that the last device on the bus sup-
plies termination power to itself. Read the device documenta-
tion if you are not sure whether the SCSI device provides
termination power.
9
Connect all power cables to the SCSI devices. Then power up
all the devices.
10
Insert the SlimSCSI 1480 into one of your portable PC’s Card-
Bus slots.
11
Power up your portable PC.
Next, you must install the SlimSCSI Windows 95 driver.
