SCSI Guidelines
29-2
6. Theoretically all eight SCSI IDs can be used. However, feedback from users has shown us
that many people have problems with more than 5-6 devices in a chain. If you have 7 or 8
devices and are having problems, your best bet is to make sure you have followed all of
the previous information, especially with respect to cables.
7. Connect all SCSI cables before turning on the power on any equipment connected by SCSI
cables. Plugging or unplugging SCSI cables while devices are powered on can cause
damage to your devices or instrument.
8. Authorized service centers should remove termination from the K2vx when installing an
internal drive, set its ID correctly, and terminate the drive.
9. When using a Macintosh, power up the K2vx and other devices Þrst.
10. The K2vx Þle format is a proprietary format; no other device will be able to read or write a
Kurzweil Þle.
11. The ßoppy disk format of the K2vx is DOS. The SCSI disk format is a proprietary form
that is close to DOS, but it is not DOS. Nonetheless, the K2vx can read and write to a DOS
formatted disk provided it was formatted on the PC with no partitions.
12. It is possible to view, copy, move, name, delete Þles on a K2vx formatted ßoppy disk or
removable media hard drive, with a PC or Macintosh running a DOS mounting utility
program such as Access PC.
13. As long as the SCSI bus is properly terminated there is no way you can damage your
hardware simply by operating it. There are a few hazards K2vx users should be aware of,
however:
The only damage that usually occurs to SCSI hardware comes from static electricity
"zapping" 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. One should discharge static from one's body before touching SCSI connectors
by touching the 1/4" jacks on the rear of the K2vx or another grounded metal object. Any
devices connected to the SCSI bus should be turned off when plugging or unplugging
SCSI cables.
If the K2vx is connected to a Macintosh or PC you should make sure that the computer
cannot access a SCSI disk at the same time the K2vx does (see below for more information
on this). Those who occasionally want to share a drive, but don't want to take any risks
would be best served by disconnecting and connecting devices as needed. If you want to
share drive(s) often and cannot constantly disconnect and reconnect devices, make sure
the Mac or PC is really done with the disk before using the K2vx. Furthermore, you
should quit or exit from all running programs and disable screen savers, email, network
Þle sharing, and any INITs or TSR's that run in the background. If the computer and K2vx
access the disk at the same time there will be no damage to the hardware, but the bits on
the disk, K2vx, and computer memory can easily be corrupted. You may not know that
damage has been done to these bits until weird things start to happen for no apparent
reason.
K2vx and Macintosh Computers
1. The Mac really does not like having another SCSI master on the bus (i.e., the K2vx). It
assumes that it owns the bus and its drives, therefore it will not tolerate the situation
where the K2vx is trying to talk to its (the Mac's) disk. This suggests that you never want
to select the ID of any drive mounted on the Mac's desktop. Even more fundamental is the
problem that the Mac assumes that the bus is always free, so if it tries to do anything via
