Figure 1. Jumper Location 

A block of mode select jumpers are located on the 
rear of the DVD-ROM. If a jumper covers both pins 
on the jumper block, it is ON; if there is no jumper 
or only one of the pins is covered, the jumper is 
OFF. The jumper settings include SCSI ID, Parity, 
Termination, Block Selectability, Test and Power 
Supply. 
 

 

 

SCSI ID - All SCSI devices attached to your 
computer are assigned a SCSI-ID number from 0 to 
7. Your DVD-ROMs SCSI ID must be set so that its 
ID number does not conflict with any other devices 
SCSI-ID in your system. In most cases, your DVD-
ROM will be set to SCSI ID 4 at the factory. Also 
note that your SCSI interface card in most cases 
has a SCSI ID of 7. This following chart (figure 3) 
shows the jumper settings for the eight possible ID 
numbers

Parity - In the OFF mode, the parity bit check function on the SCSI data bus is activated which 
enhances data bus reliability. Therefore, the jumper should remain in the OFF mode.
