For several jukebox types, the robot is controlled through a serial line,
which allows you to save a SCSI ID. For the NSM Mercury and Satellite jukebox,
the serial interface allows the software to fully exploit the features of the
jukebox and its ability to execute several movements in different states
simultaneously. iXOS-JUKEMAN uses this parallel capability; even under high
load the server can satisfy 14 client requests per minute for different CDs in
a single Mercury or Satellite. Moreover, you can connect 16 NSM jukeboxes to a
single serial line and all will be able to move simultaneously.
Each serial line is represented in the file system by a name specific to the
operating system. The first two serial lines are:
AIX: /dev/tty0 /dev/tty1
DEC UNIX: /dev/tty00 /dev/tty01
HP-UX 10.*: /dev/tty0p0 /dev/tty1p0 or
/dev/tty0p1 (depending
on the model)
Linux: /dev/ttyS0 /dev/ttyS1
IRIX: /dev/ttyd1 /dev/ttyd2
NT com1: com2:
Solaris: /dev/ttya /dev/ttyb
IRIX
For IRIX, see also the output of man serial.
AIX
For AIX, special serial cables that are required are available from IBM. The
messages "alarm clock during tty_open" and "open(/dev/tty1) timed
out" in the log file indicate that an incorrect serial cable is
attached.
The following section provides you with details of device description files for
server set-up. These files are needed to access the connected devices through
the server. For Windows NT, this section may be skipped, as you can use the GUI
to generate the device description files.
