Here is what you need to do to change the default input type which is 0-10V input:
1) Update the megabas command, instructions in the
readme:
~$ cd megabas-rpi/
~/megabas-rpi$ git pull
~/megabas-rpi$ sudo make install
2) run the command "megabas 0 incfgwr <channel> <0/1/2>"
where channel can be from 1 to 8 and value 0 = 0-10V input; 1=1k thermistor input; 2=10k thermistor input
For more info on the command option type "megabas -h incfgwr" and "megabas -h incfgrd"
The configuration is saved in the card nonvolatile memory so you only need to rerun this command if you decide to change the input type.
