SCSI Terminating Power 3-4 5-6 Function SHORT* SHORT* Power is supplied to the terminating resistor from the IDD and TERMPWR pin. Power is also suppiled to the TERMPWR pi n from the IDD. OPEN SHORT The TERMPWR pin is not used. Power is supplied to the IDD terrminating resistor only from the IDD. SHORT OPEN Power is not supplied to the terminating resistor from the IDD, only from the TERMPWR pin. 7-8 SHORT* Enable SCSI bus terminating resistor OPEN Disable SCSI bus terminating resistor

Notes: 1. Set the SCSI ID so that there are no duplicates between SCSI devices on the same SCSI bus. 2. The Priority of SCSI bus use during in ARBITRATION phase is determined by SCSI ID as follows: 7 > 6 > 5 > 4 > 3 > 2 > 1 > 0 > 15 > 14 > 13 > 12 > 11 > 10 > 9 > 8
