Installing the Decoder: Before installation, it is recommened to do as follows: o if you are digitizing your existing analogue system check if there is an integrated buffer capacitor remaining on the rail! o when digitizing 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.
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.
DigiSound-x.3: The decoder outputs are equipped with 8cm cables without connectors. This type is ideal for digitizing old models which do not have a printed circuit. The list below will help with installation: o Orange: Right motor terminal o Yellow: Rear light o Green: AUX1 function output...
DigiSound-x.4: The outputs of the decoder have standard MTC 21 pole interface. Index pin DigiSound-5.4 with 21MTC 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 locomotive. Incorrect installation may result in damage in the decoder! The loudspeaker 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.
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.
DigiSound-x.7: The interfaces of the decoder have 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 loudspeaker 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.

DigiSound-5.8: DigiSound-5.8 with NEXT18-S interface The interfaces of the decoder have standard NEM 668 with Next18-S interfaces. In the event of incorrect installation, no damage is done, but the locomotive will go in the opposite direction and the function interfaces can be mixed. In this case, install the device reversed.
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, braid 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.
Setting the speed of the locomotive: The 3 or 28-point speed curve can be used to determine what the actual speed gears from the rails actually represent. Since this function cannot be disabled, you should set this to your preference. Consider this: if you choose a 3-point curve and set CV5, set CV6 too! Bit 4 of the CV29 register determines if your locomotive should operate based on the 3 or 28-point speed curve.
28-point speed curve (CV29,4=1): 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 follow- ing 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.
Page 21
Speaker output, the speaker can be attached to the soldering point on the preparatory panel of the locomotive. Outputs marked in red 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 buttons that activate the output. You can specify the logic dependency (AND/OR) between the function button and the selected function button ON/OFF (activate or deactivate the func- tion button).
Page 23
Key: Number of function button: The decimal value can be 0-38. The output will not become active at value 0 or higher than 38. Optional decimal values: • 1-28 = F1-F28. • 29 = lights. • 30 = selected input (e.g.: dynamic smoke sync signal control). •...
Function output mode and „brightness” setting: Every function output includes two modes, one basic brightness and one dimmer CV regis- ter. The following chart shows the output CV allocation. Changed Basic Mode 1 Mode 2 “brightness” “brightness” Headlight CV176 CV188 CV300 CV312 Backlight...
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) registers, depending on whether the dimming function and “phase bit” is active or deactive. Lowering brightness, or imitating the “long distance light”...
Page 26
• 16: impulse 1s. Impulse output. This output can only be switched on for max. 1 second. If the “phase bit” is on the output switches on with a 1 sec. delay. • 17: impulse 3s. Impulse output. This output can only be switched on for max. 3 sec- onds.
Interpretation of 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 highest 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
Locomotive Driver Function: Using this function, you will experience a lot of difference in control 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 acceler- ation and deceleration.
Analogue mode: DigiSound-x.x decoders can be used on analogue tracks. Attention! In default manufacturer settings the analogue mode is disabled. If you would like to use the locomotive having this type of decoder on analogue track 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 module: Break module is a system that “changes” the speed commands of the command center to stop commands that applies to all of the vehicles on the track but doesn’t affect the func- tion commands and the vehicle can be stopped before the stop signal. A DigiSound-x.x de- coder will react to this command by stopping on the brake path set in CV50 or will stop by the deceleration set in CV4.
Page 33
• 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).

Page 35
The decoder sends the so-called flag bits via RailCom, which means that you get important diagnostic information about the decoder using the appropriate control panel e.g.: DigiPro- grammer v.23 or above. Flag bits Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1...
Multi locomotive operation (consist mode): DigiSound-4.x supports the so-called “advanced” consist mode. This means that the loco- motives can be driven not only by their own address but also by a common consist 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 37
The decimal number in the brackets has to be entered in the CV register. When more func- tion 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 a digital clutch can automatically disconnect vehi- cles. By enabling 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 39
The function output to which the switching mechanism is connected should be set to "Im- pulse" or "Attach Mode" in the associated mode register. In attach mode, to spare the digital clutch, the function output only gives full voltage (re- tractor) up to 250ms after switch-on, then decreases it to the level set in CV114.
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 transfer. The principle is that the locomotive decoder can be supplemented with various intelligent tools.
Saving function button status: The command center does not continuously send the status of functions F13-F28 to the track, only when it changes and only a few times. The function of the decoder is to store the function state in the non-volatile memory. It can be useful or distracting. E.g. you play with the engine spinning (F20) and then you put it away in the box and after 1 month you unpack it again and find that the locomotive does not start (engine spin remains on).
Energy supply (DigiCap, DigiPack): The sensitivity of the power-disturbance of DigiSound-4.x decoders can be reduced by a number of solutions. DigiCap It is an easier way 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 43
The bigger the capacity is, the longer it works during a power cut. Voltage tolerance should be minimum 1.5 times of the voltage applied on the track. Quick-acting Schottky diode. Closing voltage tolerance should be minimum 1.5 times of the voltage applied on the track.
Config registers CV29, CV49: The bits of the two registers controlling the main features of the decoder are the following. Config Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 reg.1 (128) (64) (32) (16) Enab.
Sound settings: Sounds and their features can be set and edited with the DigitoolsSoundEditor (DSE) soft- ware. 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 sounds. 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 a professional microphone and recording system. In order to make the best of it, DigiSound-4.x-5.x de- coders have been enabled to play 16-bit sound files. In effect, this eliminated the distract- ing background noise of converting sound to 8 bits and increased the dynamic range.
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 is being played on multiple channels. Instead of interrupting or replacing the sound 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.

Muting function: When a selected function button is activated, the decoder will slowly silence the sound, and will slowly restore the volume 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.

Example: move the F3 short horn sound to F23. To do so, write 23 in CV360. After configu- ration, button F3 will be released, the sound will be played on button F23. Function butt. selector CV register Numberf of sound starter function set in DSE program CV357 CV358 CV359...
Programming: The DigiSound decoders can be programmed in accordance with the NMRA RP 9.2.3 stand- ards 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.
