Hello Michael,
We will need a lot more information to be able to help you. Schematics so we can see how you have things wired up. We will need to see a sigma studio project, if you have one, and then the register settings you are using.
We also need to know details about your system. Are you getting signals from any other input to the 1701? So give us more detail and we will be able to help.
Thanks,
Dave T
