Number of Channels
Number of channels for this stream in each “sample
block” of the “packets” in each “frame” on the link.
0000=1 channel (not supported)
0001 = 2 channels
1111= 16 channels.
stream ID used by the converter widget. By conven-
tion stream 0 is reserved as unused.
Integer representing lowest channel used by con-
verter.
0 and 2 are valid Entries
If assigned to the same stream, one ADC must be
assigned a value of 0 and the other ADC assigned a
value of 2.
