Installation
Media Recognition System (Switch 4)
Switch 4 ON = Media Recognition System mode disabled (default)
•
Switch 4 OFF = Media Recognition System mode enabled
•
The media-recognition system allows the drive to determine whether a DAT tape supports the DDS
standard. Using non-DDS media may appear to give satisfactory results, but the inferior specifica-
tions of such media can cause data-integrity problems.
Switch 4 enables or disables Media Recognition System (MRS) mode. If switch 4 is ON (the default
setting), the drive reads or writes both MRS and non-MRS 4-mm media. If switch 4 is OFF, the drive
reads and writes to MRS media, and reads from but does not write to 4-mm media.
Parity Check (Switch 5)
Switch 5 ON = Parity checking enabled
•
Switch 5 OFF = Parity checking disabled (default)
•
Switch 5 enables or disables parity checking for the SCSI bus. If switch 5 is ON, parity checking is
enabled. If switch 5 is OFF (the default setting) parity checking is disabled, but parity is still gener-
ated by the drive.
DDS Pass-through Mode (Switch 6)
Switch 6 ON = DDS pass-through data compression disabled
•
Switch 6 OFF = DDS pass-through data compression enabled (default)
•
If switch 6 is OFF (the default setting), DDS pass-through data compression is enabled. If switch 6 is
ON, data compression is disabled.
NOTE: The setting of switch 6 can be overridden if the host computer issues the appropriate
SCSI Mode Select command.
Inquiry String (Switch 7)
Switch 7 ON = Drive identifies itself as a Seagate DAT drive (default)
•
Switch 7 OFF = Drive identifies itself as an Archive Python drive
•
If switch 7 is ON, the drive generates a SCSI inquiry string that identifies it as a Seagate DAT drive.
For compatibility with older software and operating systems, the drive can be configured as an
Archive Python drive by setting switch 7 to OFF.
