Header Block Definition - 36 Bytes - Electro Industries Shark 200 Installation & Operation Manual

A single waveform capture is the aggregation of all 26 waveform record payloads,
thus totaling 25,012 bytes in size. The resulting waveform capture contains the
following byte structure:
36
388
4098
4098
4098
4098
4098
4098
NOTE: The order of the channels is not fixed. The channel ID (first 2 bytes of the
4098 bytes) must be used to determine which channel block is being presented.
Breaking the waveform capture down further, the specific blocks (Header and Channel
Blocks) are as follows:
(NOTE: 1b = 1 byte, 2b = 2 bytes.)
