Installing Three Pioneer CD-ROM Changers on one SCSI Chain

Three or more Changers can be installed on one SCSI chain by editing the Pioneer Device Driver line in the CONFIG.SYS to add an /S: switch and an /N: switch. The /S: switch indicates the SCSI ID number of each Changer installed on the SCSI chain. The /N: switch indicates the number of discs in each specific Changer. See example below:

DEVICE= C:\DEV\DRD600.SYS /D:MSCD000 /N: 1,3,6,6 /S:0,1,2,3 /C:CDP

In the Changer with ID 0, one disc, represented by single drive letter, is accessible;

In the Changer with ID 1, three discs, represented by three drive letters are accessible; In the Changer with ID 2, six discs, represented by six drive letters are accessible;

In the Changer with ID 3, six discs, represented by six drive letters are accessible.

NOTE: For the example above, drive letters d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s will be used. Total number of drive letters within the system cannot exceed 24. If you decide to assign an individual drive letter to all six discs within each changer, you will be limited to three units on one SCSI Chain. To access all six discs in up to seven Pioneer CD-ROM Changers, use the XDISC utility, described below.

Use a Centronic 50 Pin SCSI cable to connect the third drive to the second drive on the SCSI Chain, and so forth. Terminate the last changer on the SCSI chain and do not terminate those in the middle of the chain. See Hardware Installation Guide for more information about daisy chaining Pioneer CD-ROM Changers. Assign each Changer on the SCSI chain its own specific SCSI ID.

Using XDisc to Assign Single Drive Letters to Each Changer

A special utility, XDISC.EXE, is included on the Pioneer Driver Diskette. If you edit the CONFIG.SYS file and then launch XDISC one drive letter will be assigned for each Pioneer CD-ROM Changer installed on the SCSI Chain. NOTE: Although XDISC can designate up to 8 separate drive letters, a maximum of seven units can be installed on the SCSI bus.

First, edit the CONFIG.SYS Pioneer Device Driver line so it includes an /S: switch

indicating the SCSI ID numbers of each drive installed, and an /N: switch, set to 0 for each drive you want to install. See example below:

DEVICE= C:\DEV\DRD600.SYS /D:MSCD000 /N: 0,0,0,0 /S:0,1,2,3 /C:CDP
