Terminator power
N/ND drives
There are four possible terminator power configurations for ST31250N and ST32550N drives (see Figure 7). You will not normally need to change this option and can leave the drive configured as it was shipped from the factory.
ST31250ND and ST32550ND 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 7.
