Hi, I just recieved the equipment delivered by Campbell UK and have installed it on my field site. Short Cut was not able to make a program that communicated with the second multiplexer. After changing the Pulseport and Portset channels it is now reading the second multiplexer as well.
The readings I get from the sensors connected to the second multplexer does not seem reliable though since they give very small readings of 0.000001 mV or negative readings.
I am using the following program form my logger.

I changed the excitation on hte second multiplexer from VX1 to VX2 and that seems to have solved the issues I was having.
