? Terminator Power Source Options J01A & J01B ??????
????????????????????????????????????????????????????????????????????????
? 2 & 4 ? Initiator supplies power over the SCSI Bus for terminators. ?
? Drive supplies no terminator power. ?
? 1 & 2 ? Drive supplies power for its own terminator resistor-paks ?
? but not to SCSI Bus. This is the factory setting. ?
? 1 & 3 ?
? AND ? Drive supplies power for external terminator at end of the ?
? 2 & 4 daisy chain and supplies own terminator power. ?
????????????????????????????????????????????????????????????????????????
ST-43402ND does not come with any provision to use Termination resistors.
Therefore, SCSI bus needs to be externally terminated.
