Subject: Streamdevice waveform - binary data stream with no separator

Good morning to all!


I have an equipment that sends 140 16-bit words in sequence. I want to put the 140 numbers in a waveform using Streamdevice.


The manual says:

Separator = "";
String. Affects out and in commands.
When formatting or parsing array values in a format converter (see formats and waveform record), what string to write or to expect between values?


and gives this protocol example:

array_out {separator=", "; out "an array: (%.2f)";}


How can I address my case using something like the separator idea, when I don't have a separator, but a fixed byte size for each number?


Thank you for all help!
