ZIMO Elektronik... World Class Motor Control... Exceptional Value...

ZIMO function decoders offer all of the world class features of our sound and motion decoders: programmable second address, advanced uncoupling functions, smart stopping (prevents stops on dirty track sections), updatable firmware, and RailCom.

A distinctive feature of all ZIMO function decoders is the programmable SECOND ADDRESS (CV #64 to #68), which can be used as an alternate address for passenger cars containing a function decoder.  

The SECOND ADDRESS is commonly set to the same address as the loco pulling the train.  If all cars in the train are equipped with decoders using the same SECOND ADDRESS, they can all be controlled simultaneously with a single key stroke (i.e. the interior light of all coaches are turned ON/OFF with a function key of the loco address). 

The ZIMO SECOND ADDRESS makes the simplest form of a virtual “train bus” a reality, and will certainly play a major role in future digital train technology.

ZIMO MX675 DCC Decoders offer the following features:

The MX675 is the "standard model" for Z, N and HO scale function control in the ZIMO decoder range.  It is the flagship model of our standard sized decoders, has 8 normal function outputs, and 2 low voltage outputs.

This model does not have dedicated circuitry for external energy storage.  It does have common and ground connections to easily attach additional capacitance, especially important for flicker free lighting and error free operation.

Decoder Formats:
MX675V - 10 highly flexible wires 120 mm in length
Dimensions: .99 x .59 x .16 inches (25 x 15 x 4mm)


  • 10 - Normal Function Outputs
  • 1.8A Total current with overload protection
  • 2 - 5.0V Low Voltage Outputs
  • 0.2A Total current - Convertible to SUSI
  • SUSI Compatible

Feature Summary:

  • 5 digit addressing
  • All US lighting effects with programmable timing and dimming
  • Free mapping, NMRA mapping or Swiss mapping function control
  • NMRA bidirectional communication (RailCom)
  • Short circuit protection
  • Thermal protection
  • Reliable overload protection
  • User updatable firmware

ZIMO Features and Characteristics:

  • Conforms to applicable NMRA DCC Standards and Recommended Practices.
  • Address range from 1 ... 10239, consist range 1 ... 127; Functions controlled by main or consist address.
  • Multiple CV sets, predefined or self-defined: by storing more than one CV set, a locomotive can quickly and easily be changed for various duties that require different CV settings (i.e. single locomotive or consist, layout at home or club etc.)
  • Supports Operations Mode (Program On Main) and Service Mode (Program Track) CV Programming.
  • Special programming mode called "Pseudo Programming" for Digitrax, Lokmouse-2 and other systems with only 2-digit display (up to 99).
  • Hard reset with CV #8 = 8; Optional hard reset to Alternate CV Set or sound project with CV #8 = 0.
  • Automatically recognizes and switches between the MOTOROLA and DCC protocols.
  • Operates with standard DC analog power packs, PWM power packs, and DC power supply. Motor regulation and momentum are also available in analog operation.
  • AC analog operation with Marklin transformers.  ZIMO decoders recognize the power surge that initiates a direction change.
  • User Updatable - Install the latest firmware yourself, in minutes, at no charge and without opening the locomotive. All ZIMO decoders come with this feature (including function and accessory decoders).  The new firmware is always available at no charge from the ZIMO or ZIMODCC web site. (Requires MX10, MXULFA, or other device)

ZIMO Safety Features:

  • Reliable high voltage protection and short circuit protection for motor and function outputs.
  • Thermal protection (100 - 120 C), shuts decoder down and notifies user with flashing headlights.
  • Models available for use with track voltage up to 35 V (MX644, MX699).

ZIMO Control Features:

  • Special circuitry to prevent interference from capacitors, choke coils, which are often found on motors.  In some cases removal of these components may still be beneficial (See Decoder Manual).
  • Uninterrupted operation (no stalling, stopping and new startup) during continuity interruptions of up to 1 second.  All current models of ZIMO decoders have Common (+) and Ground (-) pads available for adding external capacitors.  Many ZIMO decoders have special circuitry for adding external capacitors (SPEIKOMP, SPEIGOMP) which minimizes programming interference.
  • Uninterrupted operation on dead track sections. The decoder firmware prevents the loco from stopping when track power is lost, even while the loco is coming to a scheduled stop. This ensures that the loco can start up again even after the capacitors dissipated the stored electricity.  Note: Requires external energy storage module MXSPEIK or MXSPEIG, other similar products or self-made modules connected to the decoder.

ZIMO Function and Function Output Features:

  • 4-15 Normal function outputs and logic-level outputs, depending on decoder type.
  • 2-4 Low voltage 5.0V servo outputs, depending on decoder type.
  • SUSI interface for the connection of other external modules, most often sound modules.
  • NMRA function mapping.
  • ZIMO Free Function Mapping procedure (CV #61=98) enables mapping of any output to any function key, directional or non-directional, which is not possible with NMRA function mapping.
  • ZIMO Swiss Function Mapping (CV #61=...) for special cases such as direction dependent taillights and cab light in Swiss engines.
  • Numerous special effects:
    • Soft start for function outputs
    • Function output dimming
    • Function dependent low/high beam
    • Adjustable flasher
    • Stop light logic
    • Output time-out function
    • Firebox Flicker
    • Speed and load dependent smoke generation and fan control
  • All US lighting effects
    • Mars Light
    • Rotary Beacon
    • Strobe and Double Strobe
    • Gyra Light
    • Ditch Light - Type I and II
  • Variable cycle times and minimum dim values.
  • Special CVs for automatic uncoupling (aka The ZIMO Coupler Waltz).  After pressing the function key defined for this action, the loco backs up a few millimeters to unload the couplers then actuates the uncoupler and moves forward away from the train. The distance the loco backs-up and moves forward as well as the loco speed step is definable with CVs.

Note: On some decoders, the same function outputs can be used as either logic-level, servo or SUSI outputs.

ZIMO Common Function Outputs (a.k.a. Logic Level Outputs):

The common function output, also called a "Logic Level" output or "unamplified" output, refers to the voltage level at the terminal (0V for "off", 5V for "on").  The funtion output has an internal protection resistor equal to 10K Ohms resulting in 0.5 mA maximum available output current.

The use of the common function outputs is determined with CV settings: 

CV # 124:

  • Bit 7 = 0 -> SUSI 
  • Bit 7 = 1 -> Logic Level 

CV's # 181, 182

  • If set, the common function outputs are used for servo control.

Logic Level Outputs of [C] and [D] Types: 

In all decoders with 21-pin "MTC" interface (either a [C] - type or a [D] - type, e.g. MX634C MX634D or MX644C); the two variations differ in the execution of function outputs FA3 and FA4:

  • "D" - Outputs FA3 and FA4 are "normal" amplified outputs
  • "C" - Outputs FA3 and FA4 are "logic level" outputs

Logic-level outputs can power one LED or any other load by using an external amplifier (i.e. M4000Z)."Logic Level" outputs can be amplified by adding the ZIMO M4000Z Logic Level Function Amplifier or similar devices.

CAUTION: "Logic Level" outputs are NOT active in the default configuration of the decoder because they use the same ports as the SUSI interface (clock and data) as well as the servo-control lines.

ZIMO Train Control and Feedback Features:

  • DC braking distance, ABC (stopping on asymmetrical DCC signal), Marklin braking section,
  • ZIMO "signal dependent train control" (HLU) with speed limits in 5 steps and "stop before red signal",
  • ZIMO loco number recognition only with ZIMO DCC system and ZIMO track section modules,
  • Constant braking with two variations:
    • Always start braking immediately
    • When speed is low, stop in same place
  • RailCom - bidirectional communication hardware is found in all ZIMO decoders:
    • km/h feedback
    • CV "on-the-main" read-out and confirmed programming
    • RailCom address feedback
    • Many more RailCom applications in future software releases
