Drive Activity LED

[4]Dashed area is optional host circuitry (external to the drive) connected to host supplied optional usage plug.

Pins 1, 3, 5, and 7 are optional connections to switching circuits in host equipment to establish drive ID.

Remote Switches

Pins 2, 4, 6, and 8 are normally not grounded. They are driven low (ground) for 250 ms after a Reset

or PWR ON to allow drive to read SCSI ID selected.
