Problems When Accessing Disc Changers
Disc changer flutter can occur if a user requests access
to a CD-ROM when another user is already reading data
from another CD-ROM. The changer may then attempt
to service both requests by repeatedly changing
between the two CD-ROMs and transferring a small
amount of data each time. Because of the relatively long
time needed to change CD-ROMs, the data transfer
rate to both users will become unacceptably low.
The JukeBox Lock Time parameter in the DRM-6NX
configuration file specifies how long a user has exclusive
access to a CD-ROM during a data read operation. This
is to prevent disc change flutter in order to optimize
access speed when many users are accessing different
discs in the same changer.
The JukeBox Lock Time parameter will ensure that
when there are simultaneous requests for access to
different discs, a sizable block of data is transferred to
each user before the access is changed.
÷ If the JukeBox Lock Time parameter is set too low,
the data transfer rate will be unacceptably low.
÷ If the JukeBox Lock Time parameter is set too high,
the disc drive will time-out on a second user's request
before the first user's access is completed. This will
result in users receiving a 'CD-ROM not available'
notice.
The default setting is 0 seconds which disables this
function.
NOTE:
7 If some drive error occurs during caching/reading,Caching/Reading is
canceled and the drive and discs become disable.
Only restarting this product cam clear this condition.
Restoring Factory Default Settings
If required, you can restore the factory default settings
to your DRM-6NX , e.g. if you have disabled all network
protocols. You can use any of these methods:
÷ Web browser
÷ FTP on a TCP/IP network
÷ Reset button
Step by step instructions for each method are given
below.
NOTES:
7 The node address, the Hardware Address parameter, will remain
unchanged, but all other parameters will be restored. You will thus need
to re-assign the Internet address to re-establish the Web browser
connection.
7 All Cached data in the HDD is cleared when restoring the factory default
setting.

the user id root, which has the default password pass
(root is the user id with the highest priority).
3. Restore the default setting with the command:
get defaults
The unit will then automatically restart.
4. Log out using any of the commands quit, bye or exit
depending on your FTP version.
Reset Button
To restore the default settings using the Reset button:
1. Turn off the DRM-6NX.
