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-SW1-1 may be "on"
or "off" depending on HDD controller.
Set SW1-2 thru 8 to "on." |
