Infour-bit applications, DUTT RX1, DUTT RX2, DUTT RX3, and DUTT RX4 must be used. In multi-terminal applications, the RXsignals from two or more remote terminals should be connected through OR gates in the FlexLogic and the resultingsignals should be configured as the DUTT RX inputs.Figure 5–156: DUTT SCHEME LOGICSETTINGSETTINGSSETTINGSFLEXLOGIC OPERANDSFLEXLOGIC OPERANDSFLEXLOGIC OPERANDSFLEXLOGIC OPERANDDUTT SCHEMEFUNCTION:DUTT NO OF COMMBITS:DUTT NO OF COMMBITS:DUTT NO OF COMMBITS:Enabled = 1Off = 0Off = 0Off = 0Off = 0PH DIST Z1 PKPDUTT RX1:DUTT RX2:DUTT RX3:DUTT RX4:DUTT TX1DUTT TRIP ADUTT TRIP BDUTT TRIP CDUTT TRIP 3PDUTT TX2DUTT TX3DUTT TX4DUTT OPDUTT SEAL-INDELAY:TRANSMIT TABLETRIP TABLEPhaseSelectorPhaseSelectorRXRUNRUNDisabled = 0837012AD.CDRGND DIST Z1 PKP ORORANDAND t RST0SETTINGDUTT SCHEME BLOCK:OFF = 0ANDFLEXLOGIC OPERANDSAR FORCE 3P TRIPOPEN POLE OPFLEXLOGIC OPERANDSAR FORCE 3P TRIPOPEN POLE OP
