Using External Hard Drives

External SCSI drives can be connected to the SCSI connector
on the VS-1680. This section will explain using external (both
fixed and removable) drives with the VS-1680. For more
information about SCSI drives, see "About SCSI" ( Appendices ,
p. 5).

Selecting an External Hard Drive

Most SCSI hard drives that adhere to AV specifications will
work with the VS-1680. Bear in mind that drives that do not
meet AV specs, though not recommended for recording and
playback, are often still reliable for data storage. The VS-1680
can format a compatible drive in either 1 GB or 2 GB
partitions and can also access up to eight partitions.
Therefore, up to 16 gigabyte drives can be fully utilized by
the VS-1680.
Suggested specifications for external SCSI hard drives:
• 13 ms access time
• No or intelligent recalibration
• Active termination
• 1:1 interleave
• Slip sectoring
• Macintosh-compatible

SCSI Termination

When connecting one or more external SCSI devices to the
VS-1680, it is essential that the chain of SCSI devices be
properly terminated to help ensure successful operation.
Only one external drive in the SCSI chain should be
terminated:
• If a drive is the only SCSI device connected to the VS-
1680—or if it is the last device in a chain of SCSI
devices—it must be terminated. Connect a terminator
plug to one of its SCSI jacks, or, if it has a termination
switch, set the switch to "On."
• If a drive is not the final device in the SCSI chain, it
should not be terminated. If it has a termination switch,
make sure it is set to "Off."

Connecting a Fixed External
Hard Drive
Use the following procedure to connect an external drive to
the VS-1680.
fig.07-01hd
* Once the connections have been completed, turn on the power
to your various devices in the order specified. You can cause
malfunction and/or damage to your speakers and other devices
if you turn on devices in the wrong order.
* Always make sure to have the volume level turned down before
switching on power. Even with the volume all the way down,
you may still hear some sound when the power is switched on,
but this is normal, and does not indicate a malfunction.
1. Make sure that the power for all SCSI and audio devices
is turned off, and connect the external SCSI device to the
25-pin SCSI port on the rear panel of the VS-1680.
WARNING: Only SCSI devices can be connected to the SCSI
port on the VS-1680. Connecting non-SCSI devices (including
parallel devices, which have a similar connector) can damage
the VS-1680.
2. Turn on the power of the external drive.
3. Turn on the power of the VS-1680 with the POWER
switch on the rear panel.
