DX202
Overview
Purpose
The DX202E is offered to provide a rack mount back up solution that is
aesthetically compatible with the other R-1 rack mount units. Connected to the
Audio Deck, the DX202E mounted Exabyte drives becomes extensions of the
Audio Deck SCSI chain.
Features
The DX202 is a 2RU rack mount unit with 2 drive bays. The drive bays can
be populated with SCSI drive(s) in Kingston carriers or with Exabyte tape back
up unit(s). Shipping configuration are as follows:
DX202
Shipped with empty drive bays, (and 1 blank plug) or
With one SCSI drive and Kingston carrier, (and 1 blank plug) or
With two SCSI drives and Kingston carriers.
DX202E
Shipped with one Exabyte tape back up drive (and 1 blank plug) or
With two mounted Exabyte tape back up drives.
Power is supplied to the SCSI drive(s) or Exabyte(s) by the DX202, and
cooling for both drive bays is provided. In either SCSI or Exabyte
configuration, the DX202 is connects to the Audio Deck, (or two Audio Decks in
the case of a dual Exabyte configuration,) and becomes an extension of the
audio Deck SCSI chain.
Applications
When fitted with SCSI drive(s), the DX202 can be used to increase the
number of SCSI drive to which the Audio Deck has access. DX202 mounted
SCSI drives will receive the SCSI ID numbers 3, 4 or 5.
For single Audio Deck R-1 systems, the DX202E can be ordered with one
Exabyte drive, which can be left permanently connected to the Audio Deck. In
R-1 systems with 2 Audio Decks, (coming in version 2.0,) two Exabytes can be
configured in the DX202E, allowing simultaneous back up of both Audio Decks.
In a 96kHz, 48 track system, 4 Audio Decks are employed and the addition of a
second DX202E with 2 Exabytes will allow simultaneous back up of all 4 Audio
Decks.

Specific Sub-systems or Performance Considerations
SCSI
The DX202E uses SCSI 3 Ultra Wide storage technology. However, the
addressing scheme is SCSI 2 as the Audio Deck is designed and optimized for
a minimal number of devices. Only two Exabyte Mammoth back up tape drives
can be installed – one each bay. Although installed in the same enclosure, the
two Exabyte drives are wired on separate SCSI chains, each reporting to the
Audio Deck to which it is connected. Each Exabyte is always addressed as
SCSI ID#0 , and is displayed as such in the software directories.

User Reference
Special Setup Precautions
Care should be taken that SCSI cables or terminators are securely
connected to the SCSI ports on the DX202E. Once the cable or terminator has
been attached, complete the connection by tightening the securing screws on
the cable connector or terminator. The consequences of a compromised
connection can include marginal or intermittent SCSI bus behavior. This
condition will manifest itself as reading or writing bad data or SCSI devices not
being recognized on system power up.
System Setup
When adding a DX202E to an R-1 system,
•Remove the SCSI terminator from the Audio Deck External SCSI port
•Use the supplied SCSI cable to make a connection from the Audio Deck
External SCSI port to the upper or lower SCSI connector on the
DX202E rear panel marked Drive 1 or Drive 2.
•At the same drive position where the SCSI cable is now attached, plug
the SCSI terminator into the remaining SCSI port.
•If the DX202E is fitted with 2 Exabyte drives, and each is connected to an
Audio Deck, both the Drive 1 and Drive 2 positions on the DX202E must
be fitted with a SCSI terminator.
In any R-1 configuration, the DX202E will be at the end of the SCSI chain
and must be terminated.

Configuration Options
The DX202 can be ordered in several configurations to expand the
recording and/or storage capabilities of your R-1 system.
Configured for SCSI drive use:
Configured for Exabyte back up or Exabyte/SCSI combination
Power On Sequence
Power on the DX202E any time before the Audio Deck is powered up. The
Audio Deck will search for connected drives on power up and automatically
load recognized drives.
NOTE: The DX202E must always be powered on whenever it is connected
the R-1 system and the R-1 is running. As part of the Audio Deck SCSI chain,
the DX202E must be active to insure proper termination and performance.
