NOTE:
1.
SE 6 m cable applies to SCSI devices running at or below fast-5 data transfer rates.
2.
For interconnects supporting LVD/SE multimode, the larger conductor size should be
used.
3.
The conductor size recommendations assume voltage drops only due to the cables
(that is, they do not include voltage drops due to connectors, ground effects, and so
on).
