W/WD drives
Terminator power
There are four possible terminator power configurations
for ST31250W and ST32550W drives (see Figure 12).
You will not normally need to change this option and can
leave the drive configured as it was shipped from the
factory.
ST31250WD and ST32550WD drives should be config-
ured with a jumper connecting J1 pins 1 and 3 (and no
jumper on J1 pins 2 and 4) as illustrated in Figure 12.
