Setting The Scsi Id; Check The Terminating Resistor - ADIC AIT 100D Installation And Operating Manual

Setting the SCSI ID

Depending upon your setup, operating system and number of SCSI devices on the bus, you may have to
change the SCSI address of the AIT-70
See Figure 6.
The SCSI ID switch is located on the rear of the AIT-70
the + or the - button to select the proper ID.

Count each device's SCSI ID in sequence 0 to 15 on each SCSI bus to confirm that no two SCSI devices
have the same ID.

Check the Terminating Resistor

SCSI buses require termination at each end for proper operation. A typical external subsystem installation
would be terminated at the SCSI host adapter and at the last device in the chain.
If an external device were being used with an internal device (on the same channel), the SCSI host adapter
would be in the middle of the bus rather than at the end. In this case, the termination would be at the internal
