Bits 23..16 describe the data offset to store a conversion at time t, and 
bits 3..0 describe the conversion control code that will take effect 
two conversions in the future, at time t+2. On the NI 9203, bit 3 determines 
whether the result is bipolar (signed) or unipolar (unsigned), and bits 2..0 
are the channel number reversed.

So, for example, the scan list entry 0x00010006 indicates that this scan gets 
stored at address 1, and the conversion two is a bipolar channel 3 
(3 reversed = 6).
