Jumpers

RODIME RO 5065/5090 RIGID DISK DRIVE USER MANUAL PN USM-21550

Jumper Setting
==============

x = Jumpers set at factory

Up to four drives may be connected to any host in a daisy-chain
fashion. Drive numbering is effected by drive selector pins which are
connected by means of a jumper provided. To identify a drive as
number 1, short the pins furthest from the EPROM. All daisy-chained
drives should have the line terminator pack removed except for the
last drive in the chain.

All drives are shipped for single usuage; drive 1 selected and the
terminator pack present.

Note that in the multiple drive configuration, all the DATA interface
lines are radially connected to the host.
