MISCELLANEOUS TECHNICAL NOTE

Note:When connecting additional SCSI devices, the user must make sure that proper termination is used on both ends of the SCSI bus. This controller is factory-configured to be the first SCSI device on the SCSI bus. Termination is supplied by resistor packs RP3, RP4, and RP5.
