C141-E123-01EN 1 - 23(4) MATED 1/Backplane SideThe signal shall be held to a ground level when the MATED 2 connection is completed. TheMATED 1 signal shall be held to the open level when the MATED 2 connection is not completed.MATED 2connectionFigure 1.15 Circuit for mated indications1.4.3 Internal terminal resistor and power supply for terminating resistorThe TERMPWR signal of the interface connector supplies the power to the terminating resistorcircuit connected to both ends of the cable. To attach a terminating resistor to an external SCSIdevice or to cut the power of SCSI device having a terminator, the terminator power must besupplied to the TERMPWR line from any of SCSI devices of the bus. The SCSI device (such as ahost adapter) which always operates as the INIT should supply the power. The terminating resistorpower shall be supplied to the TERMPWR line through a diode to prevent a reverse current.Table 1.10 lists the requirements for terminating the resistor power supply (Vterm).Table 1. 10 Requirements for terminating resistor power supplyTerminator TypeSE (P Cable)Terminator PowerCharacteristics 0.2V dropoutregulatorLVDSE and LVDtype(Multimode)I min(A)@V min 0.6 0.6 0.5 0.65V min(V)@I min 2.7 4.0 3.0 3.0V max(V)@ allconditions 5.25 5.25 5.25 5.25
