User Manual ID Drive 1.2
5
2.4 SCSI termination
The SCSI devices which are located at the two ends of the SCSI bus must be termina-
ted. All other devices must not be terminated.
The ID Drive should be always the last device in the SCSI bus. Therefore the SCSI ter-
mination should be always on.
Switch 6
enables or disables SCSI bus termination on the ID Drive as follows:
Switch 6
Termination on*
Switch ON (down)
Termination off
Switch OFF (up)
* = Factory setting
2.5 Terminator power
One of the SCSI devices must provide the power supply for the termination, the so-
called terminator power.
Switch 5
is used to enable or disable the terminator power for the ID Drive. This is
normally unnecessary because terminator power is supplied by the SCSI controller.
If the SCSI controller or the other SCSI devices do not supply terminator power,
enable it as follows.
Switch 5
Terminator power on
Switch ON (down)
Terminator power off*
Switch OFF (up)
* = Factory setting
2.6 Factory settings
