NumChannels
Number of active digital out channels.
uint16[N] SourceChannels
Variable-length array of input numbers, indicating which analog
input is mapped to each active digital out channel.
(N =
NumChannels
).
E.g.
SourceChannels[0] = 2 => digitalOut1 = input2
SourceChannels[1] = 5 => digitalOut2 = input5
SourceChannels[2] = 4 => digitalOut3 = input4
SourceChannels[3] = 65535 => digitalOut4 = triggers
Main units may transmit input numbers as follows

Samples Packet
This packet contains measured digital samples. The samples are delivered in bundles. A
bundle contains a sample for every channel for the same time instant, and cannot be broken
into multiple sample packets. In other words, the samples are delivered as channel-
interleaved and the samples of every channel from a single moment in time are delivered
within the same sample packet.
This packet also describes the sample index and time stamp for the first sample contained.
The Samples packet structure is shown below:
