Page 2 Non-Sound Decoder MX618 - MX638 and Sound Decoder MX640 - MX659
1 Overview
These decoders are suitable for N, HOe, HOm, TT, HO, OO, Om and O gauge engines.
They operate in the NMRA-DCC data format as well as the MOTOROLA protocol, in DC analog
mode with DC power packs (including PWM) and with AC analog (Märklin Transformers with over-
voltage pulses for direction change. Exception: MX621 and MX640)).
