MCM-100/102
4 Operation
Operation of the MCM-100/102 is described here to assist in
configuration and programming of the module. Functions
addressed include analog input and GPI/O.

Analog Input Front End Configuration

Input Configuration: Differential/Pseudo-Differential
Differential input mode provides anode and cathode inputs of the
BNC connector that respond to signal voltage differences
therebetween. If the signal source is ground-referenced, the
differential input mode can be used for common-mode noise
rejection.
If the signal source is a floating signal, setting pseudo-differential
input mode will provide a reference ground connected to the
cathode input of the BNC through a 20 k
Ω
resistor.
Recommended configurations for the signal sources are as
follows.
