Dynamix MUX Object
The MUX Object (class code 0x39B) defines and controls the multiplexing
capability of the main module that is based on single or multiple
configurations. Up to three subchannels can be configured each based on one
DSP stored configuration and each having up to four time slots for which
measurement channels can be enabled in either single or parallel mode. This is
as long as the DSP can process each configuration option
Main setup for multiplexing operation using single configuration or multi-
parameter mode is under high-level configuration control. This determines the
number of subchannels and the allocation of channels to time slots. Settling
and Data Acquisition times for the time slots are automatically set at minimum
acceptable values that take account of signal processing requirements.
