Adaptec 39106 사용자 설명서

You use SCSISelect to control the termination of the two SCSI chan-
nels on the Adaptec SCSI Card 39160. The default termination set-
ting for both channels is Automatic. This setting allows the SCSI card 
to adjust SCSI termination automatically, depending on which con-
nectors have SCSI devices attached to them.

Regardless of the SCSISelect termination setting, the SCSI card termi-
nation is always disabled when the power is turned off. If you want 
SCSI card termination to be enabled when the power is turned off, 
you must terminate the SCSI channels manually.

To manually terminate Channel A, place a shunt on jumper J5. To 
manually terminate Channel B, place a shunt on jumper J3. The fol-
lowing diagram shows where the jumpers are located on the SCSI 
card:

You might want to manually terminate the SCSI card if the Adaptec 
SCSI Card 39160 is connected to one or more external SCSI devices 
that are also connected to a SCSI card in another computer. The 
devices can be shared between the two computers if one SCSI card is 
terminated when it is powered off, while the computer with the 
other SCSI card is using the SCSI devices.
