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.
