Setting robot control modes
To determine which interface will control CHM motion, you can
set the library to one of the following control modes:
SCSI Interface
LCD Interface
25-Pin or 9-Pin (narrow libraries)
25/9-Pin (wide libraries)
These control modes allow you to operate the library with the
application software (SCSI Interface) or perform diagnostic
functions on the library (LCD Interface, 25-Pin, 9-Pin, 25/9-Pin).
Refer to the following section for control mode descriptions. Refer
to page 69 for instructions about changing the control mode.
Note: Control mode settings remain through power cycles.
SCSI Interface mode
In SCSI Interface mode, your application software controls the
motion of the CHM by issuing SCSI commands across the SCSI
bus attached to the library.
Note: The application software can issue commands to the
library regardless of the control mode. However, the
library must be in SCSI Interface mode for the software to
control the motion of the CHM.
For detailed information about the SCSI commands supported by
the Exabyte 440 and Exabyte 480, refer to the EXB-440 and EXB-480
8mm Libraries SCSI Reference.
