The majority of SCSI cables weÕve tested were poorly made and could damage data
transferred to and from the disk. Nearly all the SCSI data problems Young ChangÕs
engineering department has encountered have been due to bad cables that didnÕt twist
pairs of wires properly. Correctly made SCSI cables have one ground wire for every signal
wire and twist them together in signal/ground pairs. Cables made by APS Technologies
(800-233-7550) are very good and are highly recommended. Young Chang manufactures 1
and 2 meter 25-25 SCSI cables, that we can also recommend. Good cables are essential to
reliable data transfers to and from the disk drive.

followed all of the previous information, especially with respect to cables.

damage to your devices or instrument.

hardware simply by operating it. There are a few hazards you should be aware of,
however:
The only damage that usually occurs to SCSI hardware comes from static electricity
discharging to SCSI connector pins when the cables are disconnected. The silver colored
shell of the SCSI connector on the end of the cable is connected to ground and is safe to
touch, but the brass colored pins inside eventually lead to the SCSI interface chip and are
vulnerable. You should discharge static from your body before touching SCSI connectors,
by touching the 1/4-inch jacks on the rear of the K2600 or another grounded metal object.
Any devices connected to the SCSI bus should be turned off when plugging or
unplugging SCSI cables.
If the K2600 is connected to a Macintosh or PC you should make sure that the computer
cannot access a SCSI disk at the same time the K2600 does (see below for more
information on this). If you occasionally want to share a drive, but donÕt want to take any
risks, you should connect and disconnect devices as needed. If you want to share drives
often and cannot constantly disconnect and reconnect devices, make sure the Mac or PC is
really done with the disk before using the K2600. Furthermore, you should quit or exit
from all running programs and disable screen savers, email, network Þle sharing, and any
INITs or TSRs that run in the background. If the computer and K2600 access the disk at the
same time there will be no damage to the hardware, but the bits on the disk, K2600, and
