Hi Mark, > Hi. I'm trying to do some experiments using the tdma.conf file. I wonder > what is the minimum value to reserve for the sync frame in the cycle > begining? Is it 200 us? If the master (the one that is sending the sync frames) is meant to be the first station transmitting a data frame after the sync frame in each cycle, you can set the offset to 0 in tdma.conf. Because both frames, sync and data are send by the same station (the master), RTnet will take care, that there will be no collision. As a sideeffect, this will minimize the gap between sync and data frame.

I would give it a try, if you encounter problems with this setup, increase the offset.
