The command station, the heart of the ZIMO system, generates stabilized power to the track, a standardized DCC signal as well as the MOTOROLA format. Being the CAN bus central unit, it also processes data from the cabs connected (loco speed and functions, programming procedures etc.) as well as from a possibly hooked up computer;

It also manages and controls other ZIMO products, such as accessory and track section modules.

The track voltage can be adjusted between 12 and 24 Volts to accommodate all scales and provide optimum conditions for any kind of operation. The high output current of 8 Amps is enough to power 10 or more HO trains or 5 or more large scale engines simultaneously. ZIMO's high output MX1HS delivers even more power with 2x8 Amps for two separate layout sections or, used in parallel, for one large section.

However, ZIMO's command stations are more than simple high powered digital central units: the big difference to command stations of other DCC systems becomes apparent when looking at the informative display showing voltage and amperage to each track outlet and the status of the CAN bus, it's 8 inputs for  automated shuttle train operations and for future expansions ("automatic operations"), the software development possibilities in directions of operational control and train surveillance techniques (block control at first).


Front view including the MX1 (MX1HS) display:

  • 3  LEDs (MX1HS: 4 LEDs) show the units actual status: Input voltage, track voltage, short circuit, transformer input too low.

  • The illuminated display with 2 x 16 digits is normally used to indicate track voltage and power (separate for main and programming track at MX1, or the two track outputs at the MX1HS), as well as for the CAN bus activity (C..%) or CAN bus error (E..). Product and version number will be shown depending on system state; help information is shown in the scope of programming procedures (initiated from connected cabs).

  • The red adjusting knob is used to regulate the track voltage (12-24V), the MX1HS features two regulators.

Back view of the MX1 (MX1HS)
  • Socket for external transformer (MX1HS: 2 sockets for 2 Transformers),

  • Two identical sockets, wired in parallel ("Western", 6 pin  "Telephone", "modular jacks") for CAN bus, to connect cabs, accessory modules,  track section modules, infrared and radio cabs, turn table modules, computer and possibly future system components,

  • 8 switches to select data format (protocol), various particular selections (programming protection, clear memory,.....) and booster number (MX1HS used in slave mode),

  • 8 auxiliary inputs for shuttle train operation, future "automatic operations", external emergency stop button,

  • Sockets for main track (SCHIENE 1) and programming track (PROG),
    or (with MX1HS) to track 1 (SCHIENE 1) and track 2 (SCHIENE 2),

  • DC and ground connections (ahead of DCC end stage) for uses such as, the supply of the     MX7,

  • 4 pin control bus socket to connect boosters (ZIMO MXBOO or MX1HS) as slave units but    also 3rd  party products using a control bus,

  • RS 232 Interface.

Configuration Variables of the MX1 (MX1HS):

Similar to configuration variables in decoders, general system settings can be configured and certain sequences and functions defined; access to the command station CV's is possible with any cab connected.

The RS 232 Interface

does several tasks:

  • Updating the command station by downloading a new software version, available at the ZIMO web site, into the units own flash EPROM; in the future, connected cabs and modules can also be updated provided they too contain a flash EPROM.

  • Several software products can be used for driving, switching and programming with a computer, especially suitable is E. Sperrer's programming software "ADaPT".


The Starter Sets:

The command station MX1 (or MX1HS) is usually obtained as part of a ZIMO starter set. Additionally, a cab, one or two decoders for the selected scale, the necessary cable and connectors and a ZIMO manual (which not only contains the information of the starter set but of all ZIMO components) is part of a starter set. NOTE: The necessary transformer is not included; TRAFO25 is recommended by ZIMO, but any other transformer can be used (ca. 24V, min 150VA).
