AMUX-64T Block DiagramThe AMUX-64T multiplexers are controlled by a 4-bit scanning counterthat is loaded via the 4-bit digital I/O port A of the MIO board. The MIOsignal EXTSTROBE* loads the value at digital I/O port A into theAMUX-64T scanning counter. The MIO signal SCANCLK, which is activeduring scanned data acquisition, switches the input channels automaticallyon the AMUX-64T after each A/D conversion.CH0CH1CH2CH3Jumper W1IC Temperature SensorCH60CH61CH62CH63Multiplexers64 Analog Inputs50-Pin I/O Connector16 Analog Inputs50-Pin I/O ConnectorScanningCounterDIP Switch4DIOA<3..0>2TimingLinesMUX Addressand EnablesToMIO boardTo SecondAMUX-64T(Optional)PowerConverterExternal+5 VSwitch+5 VLED+5 V+15 V-15 VSignalConditioningArea••••••••••••••68-Pin I/O Connector
