Terminator power
There are four possible terminator power configurations
for the ST15150N drive (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.
The ST15150ND drive should be configured with a
jumper connecting J01 pins 1 and 3 (and no jumper on
J01 pins 2 and 4) as illustrated in Figure 12.
