Hi, Vishwa, The software installed by following the ADC16 user guide had not been updated with the newer version of the adc16 code that supports demux mode. I have updated the software that the user guide points to, so if you reinstall the adc16 gem as per the user guide you should get version 0.4.0 which supports demux mode.
Thanks for bringing this issue to my attention.
