NI 4302, 4303, 4304, 4305 Simultaneous Tasks
The 4302, 4303, 4304, and 4305 can run up to four analog input tasks simultaneously, each using independent timing and triggering configurations. Each task uses at least one of the four timing engines on the device.
Each timing engine can control up to eight channels. If a task has more than eight channels, NI-DAQmx automatically uses multiple timing engines for the task, synchronizing and sharing settings across all timing engines. For example, if a task has 10 channels, NI-DAQmx uses two timing engines for the task, which leaves two timing engines for other tasks. If the task has 32 channels, all four timing engines are used for one task.
Each bank of 8 ADCs (ai0:7, ai8:15, ai16:23, ai23:31) must all be in the same sample mode (buffered or hardware timed single point). For example, if ai0 is used in a task configured for hardware timed single point, any task using ai1:7 must also use the hardware timed single point sample mode.
Each channel's gain can be independently configured regardless of what task it's in or what sample mode it's used with.

The 4302, 4303, 4304, and 4305 have four timing engines. Each of these timing engines can have its own configuration settings for timing, triggering, and the sample mode (either buffered or hardware timed single point).
