Page 2 Non-Sound Decoder MX618 - MX634 and Sound Decoder MX640 - MX648
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)).
