- Note 1:
- When J8 is used for SCSI ID setting, jumper plug of Bit 20,21,22
of JP248 must be removed.
- Note 2:
- When ID polarity pin is shorted to ground polarity of all SCSI
ID bits 2^n (n=0,1,2) will be changed. However, such signals as
parity, motor start/stop write protect and etc are not changed.

- *1:
- The jumper plugs for J8 are colored with Blue, and can be connected
with square Pin on J8. The Blue color is used to distinguish it
from Green colored jumper socket which can not connect with square
Pin but with rounded pin. So, please don't use Green colored jumper
socket with J8.
