Switch Settings

Use this table as a guideline for configuring the 6-position dip switch on

your PMC.

Terminators - The SCSI bus (cable) must be properly terminated at each

end of the bus. The first and last device on the bus should be the only

devices that are set to terminate the bus.

Terminator Power - The SCSI terminators require adequate voltage to

properly terminate the SCSI bus. All SCSI host adapters on the bus should

be set to supply terminator power; and where possible, be located at the

end of the bus and serve as bus terminators.The terminator resistors must

be present on the first and last device on the bus only.
