[1]Closed end type 68-pin connector used. Terminators enabled.

[2]Open end type (in-line application) connector used.

[3]Host need not be on the end of the daisy-chain. Another device can be on the end with the terminator, the host having no terminator.

[4]Total interface cable length must not exceed that specified in ANSI document X3T10/1302D (including host adapter/initiator). The cable length restriction limits the total number of devices allowed.

[5]SCSI ID7 has highest arbitration priority, then ID15 to ID8 (ID 8 very lowest).

[6]Last drive on the daisy chain.

[7]Open-end type 68-pin connector used. If end device, use external terminator and closed-end type 68-pin connector.
