I managed to get some serial input from the MFC to the Arduino, however, the input was garbled! One cause of this could be that the RS 232 voltage levels sent by the Alicat MFCs are inappropriate for the Arduino to handle directly. I will call tech support tomorrow to determine their exact specs to see if all could be fixed with a simple resistor or if I will need some more serious circuitry.
However, I measured the output signal on my oscilloscope and I see that it indeed is 0-5V, which should be fine as far as the Arduino is concerned. Strange behavior.
