| Switches |
Drive Address Switch:
DS3 "on" = address 4; bit value = 4
DS2 "on" = address 2; bit value = 2
DS1 "on" = address 1; bit value = 1
Terminating Resistor Switches:
For a single drive configuration, set
all three 4-position switches to "on."
For multiple drive configuration, device
at furthest end should be all "on," and
all other devices should be "off."
Mode Switches:
Mode P = 1 enables write protect
Mode S = 1 enables hard sector mode
Mode B = 0 disables byte clock mode
Mode A = 0 disables address mark found
Mode M = 0 enables motor start at pwr-on
Mode C = 0 disables set byte/sector cmd |
