I have found this: Protocol The protocol is (partially) documented in the vendor software's "Help" window (seems to apply to MAS343, MAS344, and MAS345; the M9803R protocol is different).
See Multimeter_ICs#Metex_14-byte_ASCII for the DMM IC protocol. I looked in the software's help window, but with the sw I have there is no discussion of protocol. Maybe the note above is referring to other software. The MAS344 is not a current instrument.
