<p>Dear friends,</p>
<p><br>
</p>
<p>yesterday I managed to get the DAQ starting (using the updated software and howto instructions). However, the readout of the TDC module V1190A failed:</p>

</p>
<p>To us it looks like the parser does not account for the fact that the module contains several individual TDC units which each will produce a TDC header plus payload. And only after all TDC units were readout, finally the trailer will appear.</p>
<p><br>
</p>
<p>(As I can see, the 1n90 series ranges from 16 channels to 128 channels with the high channel number modules having several individual TDC units. Maybe, this whole issue was overlooked when writing the parser code?)</p>
<p><br>
</p>
<p>In the attachment, I send a modified version of the parser where for testing purposes it is assumed that the module has four TDC units (as should be the case for our module). Compilation of this code works, but it fails in the unit test with the following
errors:</p>

<p>For comparison, I also send the parser from the NURDLIB version that Bastian had set up for us.</p>
<p><br>
</p>
<p><br>
</p>
<p>It would be really great if you could have a look into this. Most probably this is the last issue that we are facing, before the DAQ is fine again.</p>
