CONTROL HOOKUP
With the CR6, the Flexi-Mux connects to an available 12V port and a Ground terminal for
power. One control port is used for
Reset
and another is used for
Clock
. If two control
ports are not available (depending on the datalogger) a switched excitation channel can
be used. The Flexi-Mux only requires 2 volts to be clocked.

Reset
The reset line is used to activate the Flexi-Mux. A signal in the range of +2.0V to +10VDC
applied to the reset terminal activates the multiplexer. When this line drops lower than
0.9VDC, the multiplexer enters a quiescent, low current drain state. In the quiescent state
