 TP  Terminator Power
 --------------------
   4+-+-+3   Initiator supplies power over the SCSI Bus for
    |X+-+    terminators. Drive supplies no terminator power.
   2+-+-+1

   4+-+-+3   Drive supplies power for its own terminator resistor-paks
    +-+-+    but not to SCSI Bus. (Default)
   2+xxx+1

   4+-+-+3   Drive supplies power for external terminator at end of
    |X|X|    the daisy chain. Terminator resistor-paks must be
   2+-+-+1   removed. This option is recommended only for last drive
             on daisy-chain. (This option only on Single-Ended drives)
