Thanks all for the kind help. This did point me to the right direction. I was now able to make v1720.c as well as my MIDAS frontend (thanks to
Jimmy's example) talking to V1720, and read out the waveform bank.

I would like to know whether all parameters used by the frontend code have to be in the "Experiment/

big section of experim.h (EXP_PARAM_DEFINED). I have parameters the various frontends read at the

Does somebody have experience with this? I use the following settings for the ODB mlogger channel settings: Type: FTP, Filename: server.com, 21, user,
pw, ., run%06d.mid, Format: MIDAS, Output: FILE. What would be the Output: FTP setting for? I tried this but it does not work at all.

Thanks you two once again for the very fast answers. I tested the example on the local machine and it works perfectly fine. In the meantime I also created
two new drivers for our devices
