Enable termination on a SCSI channel if the controller is installed at one end of that channel. This setting terminates the channel and power s its SCSI TERMPWR signal. Disable termination on a SCSI channel if the controller is not at the end of that channel (both external and internal devices exist on the same channel). | ||||
