32 Hawk 2 (Wide bus) Family Install Guide, Rev. C

J6 and J1-Auxiliary

Jumper

Installation Jumper Function Description

A3,A2,A1,A0* Drive ID on SCSI Bus. The drive ID is binary coded positionwise i.e., jumper in position A3 is drive ID 8, in position A2 is drive ID 4, in position A1 is ID 2, position A0 is ID 1 and no jumpers is ID 0. Default is ID = 0.

 

Either J1-auxiliary or J6 may be used to select

 

drive ID. Both should not be used at the same

 

time, because at some future time when the ID

 

is changed the user could fail to configure both

 

J1-auxiliary and J6 the same. Default is ID =

 

0.

SSP*

No jumper ever installed. Used only as a cable

 

connection for the reference index signal

 

(REFIND+) (J6 Pin 6, bottom) for sync spindle

 

feature. J6 pin 10 is GRD. Installing a jumper

 

between pins 5 and 6 will cause an erroneous

 

drive ID indication.

BUSY Connection for optional external Drive Busy indicator.

VENDOR Connection for optional indicator for custom use.

UNIQUE See host system documentation. EXTERNAL Optional indicator indicates some external to

FAULT drive fault occurred.
