Thanks, this protocol makes sense. No doubt Emu did it this way so they could reuse the SDS sample dump code. Can you confirm that the Emax always waits for an

If the Emax bank dump protocol uses the same format as the MMA SDS data packet then each packet only requires 127 bytes. That should not be too difficult to

Sorry, maybe there was some confusion. I was referring to using the DSO for investigating the waveforms of the RS422 signal, not for analysing the protocol.
