These are the two connectors that should be configured for all these drives:

J2 should have a jumper to set the termination power from SCSI bus (see above drawing). For LW drives,

the Force Single Ended Jumper, must also be installed.

The Data-Express carrier should be connected to the drive with 3 cables:

1. Power Cable

2. SCSI Cable

3. SCSI ID number cable: this cable is supplied by Kingston with the Data-Express and has one 3 pin

connector (5 for wide) that connects to the Data-Express carrier, and three (five for wide) 2 pin

connectors that should be connected to the drive. Note that each of those 3 wires is connected to only

one side of the 2 pin connector. That side with the wire should be connected to the top row of J6 (J5 for

wide) if you are looking straight at the front of the drive (back of the drive for wide). On the wide

drives the yellow cable should not be connected to anything.

Extra care should be given as to not have cable number 3 described above be caught between the drive and

the Data-Express carrier chassis.
