Power connector
The STR912FAW44 parallel interface to hard disk demonstration board can be powered up
by having ATX-SMPS (J5), a 12 V, or a 15 V power supply connected via an external power
supply jack (J7). The current rating should meet the hard disk ratings. Usually 15 V 2 A (or
12 V 2 A) adapters are suitable.
