Drive Address Switch:
SW2-1 "on," all others "off" = addr 1
SW2-2 "on," all others "off" = addr 2
SW2-3 "on," all others "off" = addr 3
SW2-4 "on," all others "off" = addr 4
Terminating Resistor Switch:
Serial configuration-SW1-1 always "off";
if one drive, set SW1-2 thru 8 to "on."
If more than one drive, set SW1-2 thru 8
to "off."
Parallel configuration-set SW1-1 thru 8
to "on" for all drives.

Drive Address Switch:
DS-1 "on," all others "off" = addr 1
DS-2 "on," all others "off" = addr 2
DS-3 "on," all others "off" = addr 3
DS-4 "on," all others "off" = addr 4
Terminator Resistor Switch:
Contacts "2" through "8" of far-end
drive must be "on," and any other drives
must be "off." Contact "1" is for radial
connection and is enabled when "on."

SW2-2 "on," all others "off" = addr 2
SW2-3 "on," all others "off" = addr 3
SW2-4 "on," all others "off" = addr 4
Terminating Resistor Switch:
Serial configuration-set last drive
SW1-1 "off" and SW1-2 thru 8 to "on."
For other drives, set SW1-1 thru 8
to "off." Radial configuration-for
all drives, set SW1-1 thru 8 to "on."
