Hardware Setup and Configuration

The jukebox arrived without cables or manuals. Jonathon Lennox ordered corresponding SCSI manuals and Raj Kumar found a suitable 68 pin SCSI-2 to centronics cable which could be used for connection to either the Sparc Ultra ind.cs or the Gateway 2000 Pentium-Pro njt.cs.

A power cable was easily obtained from the lower storage area of the IRT Lab. Initially, however, when powered-up the jukebox did not respond to attempts to engage any of the self-tests. The problem was a blown 1.5A/125V fuse located behind the upper back panel (H107-H108). I replaced it with a similar fuse found in the CRF supply room (correspondence).

Door Open

Since the jukebox was not at the time connected to any machine, it was necessary to manually terminate the first of the CDROM drives by setting the two dip switches on the right side of the drive down (see illustration).

At this point it was possible to enter the test mode by opening the door, inserting the 'door-jig' (I used a pen cap) into the safety-switch socket located midway down on the right side, and pressing and holding the TM button for 3 seconds.

When in test mode, the LED Display window at the top of the jukebox lights up displaying the changer firmware version. This is mode 0 as signified by the far left digit of the display. The user cycles through all 7 modes using the MD+ button. Within each mode there are several submodes indicated by the 2nd digit from the left. These submodes can be cycled through using the SM+ and SM- buttons. The three digits on the left display coded information. The four buttons on the right (S1, S2, S3, S4) are used to manipulate this information.
Example: 20-XXX refers to mode 2 submode 0. XXX corresponds to information-- in this case, an error code in NVRAM.

The useful debugging modes are:

In Mode 4, illegal moves are prevented, an error is reported and the red exception light starts flashing. To continue after an error occurs, it is necessary to acknowledge the error by cycling the MD+ button past the error history modes (1 and 2). The manual advises caution when using Mode 3, as illegal and potentially damaging moves are not blocked.

Aging Mode (5) will work for one complete cycle only. By repetition, it was found that the all discs were not returned to their original positions; The were all situated one slot down respectively. The aging mode expects the discs to be returned to their original positions, so an error was reported and the test halted after only one cycle. Pioneer Tech support suggested the re-initialization of the jukebox using WMOUNT.EXE However, this software could not be run on njt.cs because it lacked a specific SCSI software installation (similar, but older software exists on view.cs, but its installation did not seem to effect any change). Regardless, the problem appeared only to effect the operation of the aging test mode (correspondence).

The general procedure to load a CD from slot XYZ of a loaded magazine into a drive:

1. Enter Test Mode by pressing the TM button for 3 seconds
2. Select Test Mode 4 by pressing the MD+ button 4 times
3. In submode 0 (by default, or use SM+), enter the slot number XYZ by pressing
   S1 X times
   S2 Y times
   S3 Z times
4. Execute the disc transporter movement by pressing S4. The transporter will now move to slot XYZ
5. Enter submode 1 by pressing SM+ and Move the arm to the appropriate side of the magazine:
   Left=S1, Right=S3
6. Enter submode 2 (SM+). Extend the slide into the magazine by pressing S1
7. Enter submode 3 (SM+). Close the chuck to secure the CD by pressing S1
8. Enter submode 2 (SM-). Retract the slide by pressing S2
9. Enter submode 1 (SM-) and Move the arm back to the center by pressing S2
10. Enter submode 0 (SM-), and enter the slot number of the target CDROM drive by pressing
    S1 X times
    S2 Y times
    S3 Z times
    For Drives 1 and 2 use 514
    For Drives 3 and 4 use 528
11. Execute the disc transporter movement by pressing S4. The transporter will now move to the vertical position of the target drive
12. Enter submode 1 (SM+) and Move the arm to the appropriate side:
    Left=S1, Right=S3
13. Enter submode 2 (SM+). Extend the slide toward the drive by pressing S1
14. Enter submode 3 (SM+). open the chuck to release the CD by pressing S2
15. Enter submode 2 (SM-). Retract the slide by pressing S2
16. Enter submode 1 (SM-) and Move the arm back to the center by pressing S2. Now the CD has been mounted in the drive
17. Recognizing the CD depends on the operating system. On Solaris use volcheck; on NT running IXOS Jukeman software, select the slot number using the GUI.

The general procedure to manually remove a CD from a drive and position it in slot XYZ are essentially the reverse of the above.
