Installing the SlimSCSI 1450
Follow these steps to install the SlimSCSI 1450 and connect your
SCSI devices to it:
1
Remove the SlimSCSI 1450 from its packaging.
2
Plug the 50-pin connector into the first (or only) SCSI device, as
shown below. Make sure the SCSI device is not powered.
If the SCSI device has a DB25 (25-pin) connector, attach the
50-pin-to-DB25 converter, as shown below, and plug it into the
connector on the device.

(Optional) Connect up to two additional SCSI devices by daisy-
chaining them to the first device, as shown below:
4
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 8.)
The diagram below shows a typical SCSI device with a select-
able SCSI ID switch:

Terminate the last (or only) SCSI device connected to the
SlimSCSI 1450. Read the device documentation if you are not
sure how to terminate the device, or refer to Terminating the
SCSI Bus on page 9.

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.
7
Connect all power cables to the SCSI device(s). Then power up
the device(s).
8
Insert the SlimSCSI 1450 into one of your portable PC’s
PC Card slots, as shown below:

Power up your portable PC.
This completes the physical installation of your SlimSCSI 1450 and

miniport driver.
