You may need additional cables or adapters to connect the 
scanner. Your cable must have a 50-pin Centronics M or DB-25 
M connector at one end for attachment to the scanner, and the 
cable should be as short as possible. To determine the connector 
you need for attachment to your SCSI adapter, refer to 
instructions with the adapter.
 
Set Termination
 
Terminate the scanner and all other SCSI devices as shown in the 
appropriate cabling diagram to the left or on page 7. The last 
device in the SCSI chain must be terminated (or termination on), 
while all other devices must be unterminated (or termination off).
Set scanner termination with the termination switch (
 
d
 
 on 
page 7). On = terminated, Off = unterminated.
Termination instructions for your other SCSI devices are 
provided with the devices.
