ZIMO decoders contain a microprocessor with appropriate software. The software version can be read out from CV #7 and #65.

The current version may not yet capable of all the functions mentioned in this manual. As with other computer programs, it is also

not possible for the manufacturer to thoroughly test this software with all the possible applications. Installing new software ver-

sions later can add new functions or correct recognized errors. SW updates can be done by the end user for all ZIMO decoders

since production date October 2004, see chapter “Software Update”! Software updates are available at no charge if performed by

the end user (except for the purchase of a programming module); Updates and/or upgrades performed by ZIMO are not consid-

ered a warranty issue and are at the expense of the customer. The warranty covers hardware damage exclusively, provided such

damage is not caused by the user or other equipment connected to the decoder. For update versions, see www.zimo.at.

Page 2 Large-scale Decoder & Sound Decoder MX695/6/7/9

1 Product - Overview

The MX695 large-scale decoder is available in 5 standard versions, 4 of them are equipped with

sound. Special versions for specific high-volume applications with slightly modified features are

also available (i.e. customized number of outputs for a specific project).

ZIMO decoders primarily operate in the NMRA-DCC data format with any NMRA-DCC compat-

ible system, as well as the MOTOROLA protocol (MM) within Märklin systems and other

MOTOROLA command stations. ZIMO decoders also operate in DC analog mode with DC

power packs (including PWM) as well as AC analog (Märklin Transformers with over-voltage

pulses for direction change).

In addition to the types presented below, there are also

loco-board and large-scale decoder combinations available: see chapter 4

OVERLOAD PROTECTION

The motor and function outputs of the ZIMO large-scale decoders are designed with large re-

serve capacities and are additionally protected against over-currents and short circuits. Automat-

ic shutoff will occur in case of overload followed by automatic reboot attempts (which often re-

sults in flashing lights).

These safety precautions do not mean that the decoder is indestructible. Please pay attention to the

following:

Faulty decoder hook-up (mixed up connection wires) and improper electric connections between the motor

terminal and chassis are not always recognized and can lead to output driver damage or even total destruction

of the receiver.

Unsuitable or defective motors (e.g. with short-circuited turns or collectors) are not always recognizable by

their high consumption of electricity (only peaks may register) and can lead to decoder damage, sometimes

long term effects can cause output driver defects.

The decoders output drivers (for the motor and function outputs) are not only at risk through over-current but

also through voltage spikes as they are delivered from the motor and other inductive consumers. Depend-

ing on track voltage, such spikes can reach several hundred volts and are absorbed by special protection cir-

cuits inside the decoder. The capacity and speed of such elements is limited and so unnecessarily high track

voltage should not be used. Never use a higher voltage than recommended for a particular vehicle. Only in ex-

ceptional cases should the ZIMO adjustable range (up to 24 V) be utilized.

THERMAL PROTECTION

All ZIMO decoders come equipped with a sensor that detects the actual temperature. Once the

maximum permissible value (ca. 100 oC on the circuit board) has been reached, power to the

motor will be shut off. Rapidly flashing headlights (at ca. 10 Hz) will signal that a shut-off has oc-

curred. Motor operation will resume automatically after a drop in temperature of about 20 oC, typ-

ically after 30 to 60 sec.

SOFTWARE UPDATE

ZIMCO decodes are designed so that software updates can be completed by the user. This re-

quires a device with an update function (ZIMO decoder update module MXDECUP, or MXULF,

or “central system cab“ MX31ZL/MX32ZL, or command station MX10).The update itself is car-

ried out via a USB stick (MXULF, MX31ZL, MX32ZL, MX10) or via a computer with the “ZIMO

Sound Programmer” ZSP software or “ZIMO Rail Center” ZIRC software.

There is no need to remove the decoder; the locomotive does not need to be opened; it can be

placed onto the update-track (connected to the update-device) without any changes and can

then be updated via a USB stick or a computer.

Note: Locomotive accessories that are directly connected to a track (not controlled by the decoder) may inter-

fere with the update; in that case the locomotive will have to be opened and removed from the track.

The following connection diagrams

are based on the MX699.

The connections on the MX696 and MX697 are placed differently, but functionally similar

3.1 Tracks and motor(s)

The loco must provide enough

space inside, so the decoder can

be mounted without exerting me-

chanical stress.

All direct connections that are

present in the original wiring con-

figuration between the power

pick-ups (wheels and wipers) and

the motor must be insulated.

The same is important for the

headlights and other additional

accessories, which must be com-

pletely insulated.

Tracks (wheels, wipers) and mo-

tor are connected to the corre-

sponding positions on the screw

terminals (pins) according to the

picture. The second connection

points (only partly available) can,

but do not have to, be used addi-

tionally.

Generally, all DC motors used in model railways can be used.

In case, there is more than one motor in the loco, those are connected in parallel and com-

bined with each other to the decoder. A parallel connection like this ensures an automatic

alignment, provided it is an identical motor- and transmission arrangement. The MX699 usu-

ally is always strong enough to handle two or more motors.

See configuration (CVs) for motor regulation!

The connection pins for tracks and motor are available twice on the decoder, to enable send-

ing the full voltage through the relatively thin cables. For a use of up to 2 A, it is, however,

sufficient to use only one pin.

3.2 Speaker, cam sensor and volume regulation

All 4 Ohm or 8 Ohm speakers can be used,

or even some speakers connected in paral-

lel, so there is a total impedance of not

more than 4 Ohm.

The sound amplifier of the MX699 works

with 10.8V and therefore presents a sinus

power of 12 Watt onto a 4 Ohm speaker;

onto an 8 Ohm correspondingly less, i.e.

about 5 Watt.

In case, tweeters are used, they are con-

nected in parallel to the main speaker via a

frequency crossover (e.g.: a capacitor of 10

μF).

Attention: for speakers with lower specifica-

tions the volume has to be adjusted to the

processable track power.

A cam sensor (to synchronize steam chuffs

with wheel rotation) is usually not neces-

sary, because the software-provided “virtual

cam sensor” is sufficient.

In case there is a real cam sensor, a mechanical contact or a photo transistor, as well as a

Hall sensor can be connected to the switch input “IN3”. The corresponding element has to

produce a low-resistance (i.e. <10K) connection between switch input and GROUND in the

desired rotation-dependent cycle.

The volume can be controlled alternatively or additionally to the CV-configuration (see CV

#266) via the connections to an external regulator in the loco.

ONLY MX695: If such a regulator is used (100K, preferably logarithmic), the regulator on

the PCB shall be set to the highest possible volume (left limit stop), unless it is used to limit

the maximum volume to protect a lower-power speaker.

Note to the decoder MX696, MX697, MX699:

These large-scale decoders (i.e. all except the MX695) do NOT have a volume regulator

on the PCB. Nevertheless, external volume control units (potentiometers, 10K for MX697,

5K for MX699) can be connected. This is NOT possible with MX696!

Page 10 Large-scale Decoder & Sound Decoder MX695/6/7/9

3.3 Consumers and low voltage outputs

“Consumers” (or function elements) is all equipment connected to the function outputs Flf,

Flr, FO1-FO13. Mostly, this is lighting equipment (light bulbs and LEDs), but also positioning

magnets, small motors, relays, etc.

Each consumer (light bulbs, groups of light bulbs or other) is always connected to the corre-

sponding function output (negative) and to one of the up to 4 positive poles (positive):

- Positive pole - full track voltage: the directly commutated driving voltage; depending on the

stabilization of the digital command station and track voltage, this is relatively unstable, i.e.

oscillates with the driving voltage.

- Low voltage - 10V: this is the voltage mostly used within the decoder to produce sound. AT-

TENTION: too much or volatile consumption by the consumers at the 10 V source can impair

the sound quality. A short circuit on the 10 V output can damage the decoder. Therefore, on-

ly use it, if there is no other possibility (i.e. the adjustable low-voltage output is already in

use).

- Low-voltage - 5 V: this voltage is provided for servos and consumers, e.g. also for common 5

V light bulbs.

Only in V-types!

- the adjustable (= variable) low-voltage: via a coding switch on the decoder PCB, which leads to

the space between FO12 and FO13, the low-voltage can be adjusted in the following steps: 1.5

V, 6.5 V, 10V, 15V.

Only in V-types!

NOTE: Rather use a low-voltage source than reducing the voltage per software (dimming

with CV #60), because dimming uses PWM reduction (full voltage impulses with a corre-

sponding duty cycle), which can damage light bulbs (not LEDs).

See chapters concerning decoder configuration (CVs) for function mapping, function ef-

fects, electrical couplers (systems by Krois, Heyn), etc.

Note to decoders MX696:

The MX696 does NOT have the (definite) 5 V low-voltage. If needed (e.g. for servos) the ad-

justable low-voltage (only MX696V) has to be used.

Note to decoders MX696N (non-sound version):

Those provide a 6 V low voltage output (instead of the 10 V low voltage of the sound decod-

ers). Due to this, servos can be supplied directly by the decoder.

3.4 Special connections for smoke-fans

Those outputs are used to control fan motors of clocked smoke generators, as they are

used in many modern locos.

The special feature of these outputs (in contrast to the “normal” function outputs) is the

possibility to brake the motor. This inhibits the motor from rotating after a current impulse,

whereby the steam-clocking gets stronger and more accentuated. The outputs are de-

signed for a 5 V motor and for a load capacity of up to 100 mA continuous current (the

start-up current may be higher).

The decoders MX695, MX696 and MX697 only have one fan output.

3.5 Servos

The MX699 provides 4 connections for common servos, which can be used for couplers,

pantographs and other mechanical equipment.

ATTENTION: Servos of different manu-

facturers all have three wires, but the or-

der and colors of the wires differ.

See chapter concerning decoder con-

figuration regarding allocation and

setting of the servos.

5V supply for servos is only available in

V-types. The control wires on the other

hand can be used in all types of the

MX695; if needed, the 5 V supply has to

be provided externally.

The 5 V supply for servos is only availa-

ble in the MX695KV, MX695LV and other

V –type models!

The control wires though are usable with

all sound decoder versions; if necessary,

use an external 5V power source to power the servo.

3.6 Switch inputs

Additionally to the switch input “IN 3” (see chapter 3.2, speaker and cam sensor) there are 3

further inputs (“IN 1”, “IN 2” and “IN 4”). These can be used to connect reed contacts to trig-

ger sounds, etc. Electrically, those switch inputs behave very similar.

See chapter concerning decoder configuration (CVs), especially regarding sound.

3.7 External stay-alive capacitor

A stay-alive capacitor (a

bigger electrolytic capacitor,

a “Goldcap”, etc. or a bat-

tery)

- improves the driving behavior on

dirty tracks (or wheels),

- reduces flickering lights

caused by interrupted contact

(e.g. frogs),

- Prevents the train from getting

stuck when driving slowly, especially in combination with the ZIMO software fea-

ture “prevent stopping on tracks without current” *),

- compensates energy loss produced by RailCom and HLU cut-outs and the corre-

sponding motor sound, additionally improves the quality of the RailCom signal.

*) In case, the current supply is interrupted (due to dirty rails or frogs), the decoder auto-

matically provides enough energy to move the train forward, even if it was currently in a

braking procedure and was supposed to stop. The train is stopped as soon as the wheel-

track-contact is reestablished. After the train stopped, the decoder tests again for track

power (if there is none, the engine moves the train a little forward until power is restored).

Generally, the efficiency of energy storage modules increases with the capacity; starting with

1000 μF (μF = Micro Farad) you can see an effect, about 100,000 μF are recommended for

large-scale locos, as far as there is enough space in the loco. Goldcap modules with a capacity

of 1 F do have a bigger effect. Too big capacities have the disadvantage of very long charging

times; this is why ZIMO recommends not more than 0.5 F for Goldcap modules (related to full

voltage of about 15 V to 25 V from a series connection of 6-10 elements with 2.5 V each; a single

Goldcap therefore has a capacity of up to about 3 F.

Proper preparations in ZIMO large-scale locos (capacitor+ connection) ensure that external capaci-

tors do not cause problems when programming decoders or updating the software (referring to

ZIMO loco number recognition via RailCom).

The charging current for the stay-alive capacitor on the positive connection is about 100 mA, i.e.

fully charging a 10,000 μF capacitor takes about 5 seconds, a 0.5 F Goldcap takes about 3

minutes.

The ZIMO Goldcap mostly used is the GOLMRUND (and the GOLMLANG), which consists of

7 Goldcaps, 1F / 2.5 V each, ergo 140.000 μF / 17.5 V in total. The capacitor+ connection on the

decoder ensures that the charging voltage does not get too high.

Using a battery instead of a capacitor can only be recommended for experts (engineering spe-

cialists); it is very important that the battery is completely discharged after taking the loco off

the supply of the tracks. Tip: a relay, supplied by the running voltage, with a capacitor hold cir-

cuit, which interrupts the connection to the battery after about 1 minute of lost supply.

Note to decoders MX699:

Contrary to other types, the MX699 also have an internal stay-alive capacitor, which consists

of 3 Supercaps in series, each with 3 F / 2.7 V, i.e. 1 F and 8 V in total. This capacitor ensures

securely passing parts without current, possibly with reduced speed. The sound supply is

guaranteed by transforming 8 V to 10 V, so the sound is fully preserved.

Nevertheless, it may be useful to connect an external stay-alive capacitor, like a GOLMRUND,

because it is charged to higher voltage (17.5 V instead of 8 V). This provides more voltage and

energy for motor and functions.

3.8 SUSI interface

The “SUSI” interface was developed by Fa. Dietz and

defines the connection of additional modules to the

decoder. Usually these are sound modules, which are

used in combination with non-sound decoders, i.e.

MX695KN and MX696N.

Additional to the sound modules, the market also pro-

vides digital couplers with a SUSI interface. Some lo-

cos have PCBs for pantographs with SUSI interface

integrated, wherefore they can use the interface on

the decoder.

Furthermore, the SUSI interface is used for loading a

sound project or update fast (with the decoder updat-

ing and testing device MXULF/A); however, this uses

faster communication instead of the SUSI protocol.

the Goldcap module GOLMRUND, often used as stay-alive capacitor

it consists of 7 Goldcaps, i.e. 7 x 1F, in total 140000 μF / 17.5 V.

4 Loco Adapter Boards for Large-Scale Decoder

Locomotive adapter boards serve as an "intermediate part" between the engine and the decoder,

to facilitate the decoder installation and connection to the various loco components. It also allows

for an easy exchange of the decoder when necessary. Additionally, some loco boards also offer

a low voltage output (i.e. for servos).

Note: Adapter boards for ZIMO large-scale decoders DO NOT contain an additional synchronous

rectifier to increase power, as do the boards for “small” decoders (for N, HO etc., see operating

manual for MX618, MX621...MX648 decoder). This would be redundant due to the very strong

and low-loss synchronous rectifier already present in large-scale decoders.

Because of the very different needs, there are a relatively large number of types or versions of

these locomotive boards available. In addition to the standard types described below, special de-

signs are also manufactured (for a minimum-order quantity of about 50, mostly for vehicle manu-

facturers) that are based on the standard printed circuit boards, but with different or differently ar-

ranged connectors.

Loco boards LOKPL95BS, -BV with solder pads,

designed for the large-scale decoders MX695LS and MX695LV

The wires from the locomotive (motor, track, lights, speakers...) are soldered directly to the solder

pads and an appropriate decoder is plugged into these boards. Depending on the type of the lo-

co board (-BS or BV), these are either simple circuit boards (no other electronic components on

the board) or a board with "additional benefits" (in this case a voltage regulator for low voltages,

which is often useful to have):

NOTE: The servo connections are NOT

accessible on the loco board. They are

therefore directly plugged in to the decod-

er (at the 3-pin sockets of the MX695).

Special applications may also contain servo

connectors on the loco board (i.e. with special

board layouts that have enough room on the

underside).

Loco boards LOKPL96...

designed for large-scale decoders MX696S and MX696V

The large-scale decoder family MX696 differs from the MX695 by their narrow designs (29 mm

instead of 40 mm). The slightly lower rating (4 A instead of 6 A) is not all that significant, but the

MX696 is not equipped as well with low voltage outputs as the MX695, in particular the 5 V –

supply is lacking. The loco boards LOKPL96.V therefore offer a 5 V source (and the complete

servo connectors), but no variable low-voltage as the ...PL95.

Combinations of loco board and decoder

Particularly useful combinations of loco board and decoder are treated as separate decoder

types (with their own names, part numbers and prices): this is especially true for

LOKPL96KS + MX696S = MX696KS

This decoder combination is similar to the type

MX695KS in terms of functions and connectivy (Screw

terminals) but is much narrower (29 instead of 40 mm).

LOKPL96KV + MX696V = MX696KV

NOTES for LOCO-CONVERSION (using the example of the Train Line HSB Mallet 995 901):

The original board in the vehicle is removed and replaced by the Zimo "Special Loco board" (with

inserted decoder MX696S). The Zimo loco board has the same connectors (but no connection

for a potentiometer) and also the same holes for the mounting screws as the Train Line original

board. The plugs are labeled on the Zimo loco board the same as the original board, i.e. J1, J2,

J3, etc. The exchange of the loco board is therefore very easy. It is recommended to first mark

the cables - at least the two-pole –in order to make the correct connections on the Zimo loco

board ... It makes sense to previously remove the decoder (for better accessibility of the loco

board connectors) and to plug it back in after finishing the installation of the loco board.

The ZIMO loco board, in contrast to the TrainLine original board, offers a connection (double

screw terminal in the lower right corner) for an energy storage device: preferably a ZIMO gold

cap module GOLMRUND or GOLMLANG.

Additionally: connections for uncouplers (for servos or Massoth uncouplers).

The conversion of the "analog version" ("A-Lok" that comes without a decoder, but does have a

loco board and connection board installed, which both have to be removed) is the same as for

the "digital" version ("D-Lok" which includes a factory-installed decoder); they differ mainly with

respect to the smoke generator. It is therefore necessary to place the 6 jumpers on the loco

board accordingly; ideally BEFORE the installation –the loco board, as delivered, is set for the

“analog version” (”A-Lok”).

The decoder offered for the HSB Mallet already contains a particularly high quality sound project

from Heinz Däppen and is optimized for this model. The decoder is also provided with a valid

load code to facilitate possible future firmware upgrades or an improved version of the sound

project. The “ZIMO & Däppen” sound offers a number of advantages for this vehicle, compared

to the manufacturer’s original digital version: prototypical chuff beats (not exaggeratedly hard),

cylinder typical “load sounds”, Mallet-typical sound even in the lower speed range, sound of aux-

iliary units from the actual locomotive.

5 Configuring the MX695 - MX699

ZIMO decoders can be programmed in

- “Service Mode” (on the programming track) for assigning a new address or reading and

writing CV content, or in

- “Operations Mode” (a.k.a. “Programming on the main” or “PoM”), which is done on the

main track; programming CV’s “on the main” is always possible in operations mode. However,

an acknowledgement of successful programming steps or when reading out CV’s is only pos-

sible with a DCC system capable of “RailCom”.

5.1 “Service mode”programming (on the programming track)

Before programming is possible, it must be unlocked with

CV #144 = 0 or = 128 (the latter allows programming but prevents decoder updating).

This (CV #144 = 0) is normally the default setting, but the programming lock is activated in many

sound projects to prevent accidental changes. It is therefore recommended to check that CV, es-

pecially when attempted programming has already failed.

Successful programming steps as well as CV read-outs on the programming track are acknowl-

edged by decoder-generated power pulses, by briefly turning on the motor and/or headlights. If

the motor and/or headlights do not draw power (i.e. they are not connected) or don’t draw

enough power, acknowledgments for successful programming or CV read-outs are not possible.

To make acknowledgments possible in such cases activate CV #112 bit 1, which enables the de-

coder to use an alternate acknowledgment by sending high frequency pulses from the motor end

stage. Whether this method is successful though depends on the DCC system used.

Attention: The CV values of a sound decoder in the delivery state do NOT correspond with

the default values in the following chapters, but rather the initial values of the loaded sound

project!

This applies most often to

CV #29 –analog operation is usually turned off (Bit 3 = 0); CV #29 = 14 turns this on if desired.

CV #144 –the update lock may be activated (Bit 7 = 1), sometimes even the programming

lock (Bit 6 = 1); before updating or programming a decoder, set this CV to CV #144 = 0.

CV #3, 4 –acceleration and deceleration CV’s are often set to higher values (i.e. 12).

CV #33 and following –the functions are often mapped to a specific loco model.

…and of course the sound CV’s (from CV #265) and (less frequently) all other CV’s.

5.2 “Operations mode”programming (on-the-main)

Programming in “Operations mode”, otherwise known as “Programming-on-the-main” = PoM

“Programming-on-the-fly”.

According to the current NMRA DCC standards it should only be possible to program and read

CV’s on the main track, but not assign new vehicle addresses. However, certain DCC systems

(among them ZIMO beginning with the system generation MX10/MX32) will allow addresses to

be modified on the main track with the help of bidirectional communication.

All ZIMO decoders are equipped with bidirectional communication (“RailCom”) and can there-

fore (with a corresponding DCC system such as ZIMO MX31ZL and all devices of the new

MX10/MX32 generation) read, program and acknowledge successful CV programming steps in

operations mode (on the main track). This requires RailCom to be activated, which is the case

if the following CV’s are set as:

CV #29, Bit 3 = 1 AND CV #28 = 3

This is usually the default setting, but in certain sound projects or OEM CV sets it may be

turned off by default and must first be turned on again.
