Host system issues a start command to the drive.
JP5 - On = Unit attention after power on reset or SCSI Bus reset
is disabled
JP6 - On = the internal active SCSI terminator is enabled
JP7 - On = Target initiated synchr. negotiation is disabled, and
then the initiator is required to start negotiation
handshake if synchr. SCSI transfers are required.
JP12 can be used to drive a LED (8mA) pin-24 is +5V

540MB, 720MB, 1GB and 2GB - SCSI-2 HDD-Jumper
The following SCSI-2 HDDs use jumpers to set the SCSI IDs, terminate the SCSI cabling chain, and
control the motor startup.
If a jumper is installed on the Bus Terminate jumper pins, the SCSI bus is terminated.
