Appendix B: Troubleshooting

Problems When Accessing Disc Changers

Disc changer flutter can occur if a user requests access to a CD-ROM while a second user is reading data from another CD-ROM. The changer may repeatedly switch between the two CD-ROM discs, sending small bits of data each time, in order to service both users. Because of the relatively long time needed to change a CD-ROM, the data transfer rate for both users may 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 and to optimize the access speed when many users are reading 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.

ÖIf the JukeBox Lock Time parameter is set too low, the data transfer rate will be unacceptably slow

ÖIf 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 transfer is complete. This will result in users receiving a ‘CD-ROM not available’ notice.

The default setting is 0 seconds which disables this function.

NOTE:

7If some drive error occurs during caching/reading, Caching/Reading is canceled and the drive and discs become disabled. Only by restarting this product can the condition. be cleared.

Restoring Factory Default Settings

If required, use any of the methods listed below to restore the factory default settings to a DRM-6NX (e.g. if you have disabled all network protocols)

ÖWeb browser

ÖFTP on a TCP/IP network

ÖReset button

Step by step instructions for each method are given below.

NOTES:

7The 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.

7All Cached data in the HDD is cleared when restoring the factory default setting.

Web Browser

To restore the defaults settings using a Web browser:

1.Start the Web browser

2.Click Administration

3.Click PIONEER Changer

4.Click Factory Defaults

The factory default setting is restored thrn the DRM-6NX reboots automatically

FTP

To restore the default settings using FTP:

1.Log in to the DRM-6NX with the command:

ftp <host name>, where <host name> is the name assigned in your system's host table

2.Enter the user id and password (Use 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 reboot)

4.Log out using one of the commands quit, bye or exit depending upon your FTP version
