Installing the Decoder: Before installing the decoder it is reccommened to do as follows: o if you are digitalizing your existing analogue system check if there is an inte- grated buffer capacitor remained on the rail! o when digitalizing old, not prepared locomotives it is essential to check if the value of the buffering capacitor is not higher than 47nF.
DigiSound-x.1: The outputs of the decoder have the standard NEM652 interface. When attaching the decoder be careful to link the orange output of the interface to pin 1 on the printed circuit, which is usually indicated with an asterisk. In the event of an incorrect attachment, no damage is done, but the locomotive will go in the opposite direction and the lighting function will not work.
Page 9
DigiSound-x.2: The outputs of the decoder have the standard 6-pole NEM651 interface. It is available in two different sizes: straight interface 90° interface DigiSound-5.2 with 90° interface In the event of an incorrect attachment, no damage is done, but the locomotive will not work.
Page 10
DigiSound-x.3: The outputs of the decoder are being shipped with customized length of cables, without interface. Let us know what length you need when placing the order. This type is ideal for digitalizing old models which do not have printed circuit for motor. The list below will help you attach the unit: o Orange: Right motor terminal...

DigiSound-x.4: The outputs of the decoder have standard MTC 21 pole interface. Index láb DigiSound-5.4 21 with MTC interface The point indicated in the picture is the „index” pin. The „index” pin is responsible for the positioning of the decoder. This pin is omitted on the preparatory panel in the locomo- tive.
DigiSound-x.5 and DigiSound-x.6: The outputs of the DigiSound-x.5 decoder have standard NEM 658, PLUX22 interface. The outputs of the DigiSound-x.6 decoder have standard NEM 658, PLUX16 interface. DigiSound-5.5 with PLUX22 interface The missing pin in the middle of the pin line is the „index” pin. On the preparatory panel of the locomotive, the holes for this pin are omitted or marked separately.
Page 13
DigiSound-x.7: The interfaces of the decoder have got standard NEM 658 with PLUX12 interface. DigiSound-5.7 with PLUX12 interface The missing pin in the middle of the pin line is the „index” pin. On the preparatory panel of the locomotive, the holes for this pin are omitted or marked separately. The loud- speaker output on the decoder is led out from the socket, so the loudspeaker must be connected to the endpoints on the locomotive’s preparatory panel.
Page 14
DigiSound-5.8: DigiSound-5.8 with NEXT18-S interface The interfaces of the decoder have got standard NEM 668 with Next18-S interfaces. In the event of an incorrect attachment, no damage is done, but the locomotive will go in the opposite direction and the function interfaces can be mixed. In this case attach the device on the different direction.
Installation: After having installed the decoder, check the position of the cables, they should not be in the way of any moving or rotating part. Pay particular attention to the cable of the loud- speaker, twist the two blades and make sure they do not touch anything electronically. If everything is fine, you may start the voltage test.

You can set the effect of load control in CV51-52. Depending on speed, the maximum per- formance of the motor output can be limited, and so can be the tractive force. In case of heavily loaded vehicles, the motor can be spared but as a result the adjusting of the speed will not be precise.The default value of CV51 in consist mode is 150 and in normal mode the default value of the CV52 is 200.
down running (default value is F6). It helps to fix the problem if you can decide if this friction in the movement comes from the turning of the wheel or of the engine. You may try to let the decoder fix the problem, e.g. by increasing only the proportionate part (CV54) (<5 values), but this is not the most ideal solution.
In this case, you do not have to worry about the CV2-6-5 registers, the speed can be set with the help of the CV67-94 registers. It is recommended to use the 28-point speed curve when you connect several locomotives, because as a result the real speed of the given speed gears of the connected locomotives can be harmonized better.
Setting acceleration and deceleration: You can set the acceleration of the locomotive in CV3, and the deceleration in the CV4 registers. The greater the value is, the longer the acceleration and deceleration is. If CV4 = 0, the delaying of deceleration is completely disabled and the locomotive moves based on the speed command coming from the rail.
Function outputs: The number and type of DigiSound – x.x decoder function outputs are shown in the following chart: Sound DigiSound-4.1 DigiSound-4.2 DigiSound-4.3 DigiSound-4.5 DigiSound-5.1 DigiSound-5.2 DigiSound-5.3 DigiSound-5.4 DigiSound-5.5 DigiSound-5.6 DigiSound-5.7 DigiSound-5.8 Key: Full value, transistor output, can be reached via the decoder connector.

Speaker output, the speaker can be attached to the soldering point on the preparato- ry panel of the locomotive. Outputs marked in red colour are not short circuit protected!!! The rest of the outputs are short circuit protected. Once the function outputs have been shorted, the output can be restarted only after a full power reset.
Function output registers: Allocating the function buttons: Every function output has got 4 CV registers in which you can choose the 4 function but- tons that activate the output. You can specify the logic dependency (AND/OR) between the function keys and the selected function key ON/OFF (activate or deactivate the func- tion key).
Page 23
Key: Number of the function button: The decimal value can be 0-38. The output will not be- come active at value 0 or higher than 38. Optional values: • 1-28 = F1-F28. • 29 = lights. • 30 = selected input (e.g.: dynamic smoke sync signal control). •...
Page 24
Function output mode setting: Every function output includes two modes, one basic brightness and one dimmer CV reg- ister. The following chart shows the output CV allocation. Basic Mode 1 Mode 2 Dimmer brightness Headlight CV176 CV188 CV300 CV312 Backlight CV177 CV189 CV301...
Page 25
• 1: Dimmable mode. The brightness of the output is determined by the values set in the Basic brightness (CV312-323), or in the Dimming brightness (CV300-311) regis- ters, depending on whether the dimming function is active or deactive. Lowering brightness can happen this way (Basic brightness > dimming brightness), or by imi- tating the “long distance light”...

• 18: impulzus 10s. Impulse output. This output can only be switched on for max. 10 second. If the “phase bit” is ont he output switches on with a 10 sec. delay. Moving: If 1 (its decimal values is 64), the output will be active only during movement. Phase: If 1 (its decimal values is 128), the below modes will be altered: •...
Page 27
Mode 2 registers (CV188-199): The direction-dependency can be assigned to the 4 function buttons of the output one by one. Thanks to this, daytime lights can operate regardless of the direction by switching on an optionally selected function button. (in shunting mode the steam locomotive moves back and forth at the same time).

Basic brightness: Adjust the basic “brightness” of the function outputs. Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 CV312-323 (128) (64) (32) (16) Value Basic brightness Key: Basic brightness: Its decimal value can be 1-64. 1 means the smallest, 64 means the high- est output voltage.
Other functions: DigiSound-4.x-5.x decoders have some internal functions that control operation on top of the physical functions as you will see below. It is their common feature that the operating function buttons can be assigned via the CV registers. The value of these registers can be 1-29.
Page 30
If this function is active, the decoder can control the smoke generator via a selected func- tion output. “Smoke” mode can be selected in the mode selector register (CV176-CV179) of the given function output. You may adjust the amount of smoke emitted in case of stopping, accel- erating and rolling locomotive.
Page 31
Locomotive Driver Function: Using this function, you will experience a lot of difference in controlling compared to the usual movements of the locomotive, they are more diverse since speeding is changing and the speed can be adjusted more accurately. By activating this function the speed command given by the remote control does not control the speed of the locomotive but the acceleration and deceleration.
Analogue mode: DigiSound-x.x decoders can be used on analogue layouts. Attention! In the default manufacturer settings the analogue mode is disabled. If you would like to use the locomotive having this type of decoder on analogue layout you have to enable this function with a digital system. To enable this function you have to switch on the second bit of CV29.
Operation on track controlled by break dynamo: Break dynamo is a system that “changes” the speed commands of the command center to stop command that applies to all of the vehicles on the track but doesn’t affect the function commands and the vehicle can be stopped before the stop signal. A DigiSound- x.x decoder will react to this command by stopping on the brake path set in CV50 or will stop by the deceleration set in CV4.

• ABC mode is enabled by setting bit 0 of CV27 and the decoder stops the vehicle if the right side of the rail is the more positive (normal ABC mode). The decimal value of CV27 is 1. • ABC mode is enabled by setting bit 1 of CV27 and the decoder stops the vehicle if the left side of the rail is the more positive (normal ABC mode).
Bit 7 (128) Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 (64) (32) (16) asymm. CV58 ABC asymmetric resistance value. RailCom: Thanks to RailCom, which is a solution by Lenz, our tools can not only receive data from the DCC signal but can also send feedback to the command center.
Page 36
The decoder sends the so-called flag bits via RailCom, which means that you get im- portant diagnostic information about the decoder using the appropriate control panel e.g.: DigiProgrammer v.23 or above. Bit mapping: • Bit0: 1, if the decoder motor detects an overcurrent. •...
Multi locomotive operation (consist mode): DigiSound-4.x supports the so-called “advanced” consist mode. This means that the lo- comotives can be driven not only by their own address but also by a common address at the same time. Consist mode can be activated by giving a consist address according to NMRA protocol, which also determines the direction of the attached vehicle.
Page 38
The decimal number in the brackets has to be entered in the CV parameter. When more function buttons are enabled the decimal values need to be summed up and this result needs to be entered in the register. Some centers don’t support consist mode activation by NMRA therefore it is possible to activate it from a function button using DigiSound-4.x-5.x.
Disconnecting function: With this function a locomotive having digital clutch can automatically disconnect vehi- cles. By pushing the selected function button the locomotive moves to the reverse direc- tion then inducts the coil of the digital clutch and then moves off the train. Disconnecting mode can only start if the locomotive stops and if the remote control is in 0 position.
Page 40
The function output to which the switching mechanism is connected should be set to "Impulse" or "Attach Mode" in the associated mode register. In connection mode, to spare the digital clutch, the function output only gives full voltage (retractor) up to 250ms after switch-on, then decreases it to the level set in CV114. It is worth finding the value where the clutch remains safely retracted.
SUSI interface: The SUSI interface has been developed by DIETZ to enable the separate modules of the locomotive to communicate. The interface uses two-way synchronous serial data trans- fer. The principle is that the locomotive decoder can be supplemented with various intel- ligent tools.
Heavy vehicle function: There is a new function in firmware v33, with which you can simulate the sluggish motion of a locomotive. As a result of activating the function button that has been selected in CV324, the acceleration of the locomotive is controlled by CV325 instead of CV3 and the deceleration is controlled by CV326 instead of CV4.
Energy supply (DigiCap, DigiPack): The disturbance of the power-disturbance of DigiSound-4.x decoders can be reduced by a number of solutions. DigiCap It is an easier way how to supply your decoder with energy. The disturbance state of the decoder can be reduced for a few 100 msec period by using a simple circuit between the soldering points of GND and V+ depending on the capacity of the capacitor and the current consumption of the active functions.
Page 44
Closing voltage tolerance should be minimum 1.5 times of the voltage applied on the track. Maximum load capacity should be 1.5 times of the locomotive load. Minimum 510Ω 0,5W. When using DigiCap, the decoder does not require any other settings. When connecting the circuit, pay particular attention to the location of the circuit and the correct soldering.

Sound settings: Sounds and their features can be set and edited in DigitoolsSoundEditor (DSE). Download the program for free from the Windows Store (software store). https://www.microsoft.com/hu-hu/p/digisoundeditor/9nfj89fbq370 For more information and for the user manual visit our website: http://www.digitools.hu/termekek/hangszerkeszto-program...
CV220-251 registers can be used to adjust the volume of different voices. CV220 is the first sound, CV221 is the second sound, and so on. A list of sounds used in a given sound project can be identified eg. opening in Digitools DigiSoundEditor (DSE) software. A locomotive’s audio may contain 32 different sounds.
16-bit sounds The sounds of original locomotives were recorded at 44.1kHz 16bit, with professional mi- crophone and recording system. In order to make the best of it, DigiSound-4.x-5.x decod- er has been enabled to play 16-bit sound files. Thanks to this, the disturbing noise that came from converting the sound to 8 bits, has ceased and the dynamic range has in- creased.
The value of the speed can be set in CV213 above which the beat of “puffing” doesn’t ac- celerate. Default setting is CV213 = 130. Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 CV213 (128) (64)
Multichannel steam locomotive sound The typical puffing sound of the steam engine will now be played on multiple channels. Instead of interrupting or replacing the voice pattern of the previous beat signal, the next sound pattern will be played on another audio channel, while the sound of the previous beat will fade.
Randomly starting sounds The sounds of your locomotives will become more diverse if certain sounds are produced randomly like the sound of the compressor of an electric locomotive or the sound of coal scooping. There are 3 random sound timers in DigiSound-4.x-5.x decoders. These sounds can be controlled separately by function buttons.
Lowering volume There is a clear sound effect of the changing engine working current in case of electric, vehicles mainly those with an inverter. It can be imitated using CV206 parameter. If there is no acceleration/deceleration the sound tracks set in DigitoolsSoundEditor fade to the rate set in CV206.
Muting function: When a selected function button is activated, the decoder will slowly silence the sound, and will slowly mute it when it is turned off. E.g.: when the train goes into a tunnel its sound mutes as well. By default, F28 is selected, CV175 =28. Bit 7 Bit 6 Bit 5...
Programming: The DigiSound-x.x decoders can be programmed in accordance with the NMRA RP 9.2.3 standards and in POM modes according to RP 9.2.1. ACK impulse: The intensity of the permitting sign of the programming commands has been decreased in order to spare the parts of the engine and the drive. This is beneficial for bigger loco- motives and does not cause any problems.
Default setting of function buttons: • F0 (FL, RL): Lighting, forward-backward, regardless of direction • F1: Main sound on • F2: Horn or whistle • F6: Shunting mode, switching off acceleration-deceleration • F5: Lowering light brightness, forward-backward, regardless of direction •...
