Thank you for choosing the product developed and produced by the

Hungarian DigiTools Electronics Ltd.

Key features:

The main purpose of this user manual is to introduce the operation and settings of the

DigiSound-4.x and DigiSound-5.x combined locomotive decoder. The serial no. 4 and 5

sound decoders are the same in terms of functions and settings, they only differ in the

size of the sound storing memory.

Hardware changes of DigiSound-x.x decoders compared to serial 3:

- The capacity of the built-in capacitors have been doubled to diminish the risk of

contact problems.

- DigiSound-x.1 (8-pin NEM652) decoder has 2 additional function outputs.

- The height of the DigiSound-x.1 decoder has been decreased: 11.2 * 24.0 * 3.2 mm.

- The size of the DigiSound-x.5 decoder has been significantly reduced (PluX22):

15.1 * 25.4 * 4 mm.

- The DigiSound-x.5 decoder has got 7 pcs. of function outputs on top of the 2 light-

ing outputs. The TTL GPIO points of the PluX22 interface, can be the CV register’s

programmable output and input (AUX8 - AUX10).

- The DigiSound-x.5 decoder has got SUSI interface for communicating with external

devices (dynamic smoke, Brawa Traxx lighting, evaluating the position).

- Preparation of our newly emerging DigiPack2 energy storing device.

- The DigiSound-4.x 64Mbit (8MB) audio memory can store 3-6 mins of audio de-

pending on the resolution.

- The DigiSound-5.x 128Mbit (16MB) audio memory can store 6-12 mins of audio

depending on the resolution.

The length of the stored audio depends on the resolution of the sounds.

Changes in version v35-36 software:

- Handling trigger sign separately as a chanel, correcting “csi-hu” timing.

- Correcting sound sample loop chacking in trigger mode.

- Setting P element overflow issue.

- Setting Aux5-10 interfaces PWM 100% filling issues.

Changes in v37 software:

- Setting Hm_out_false condition issue.

- Setting Trigger sign at start issue.

- Expanding the function of „phase” bit in function outputs.

- „Wheel sparks”, neon1, neon2, impulse mode at function interfaces.

Main parameters:

o Communication by NMRA DCC standard

o 28, 128 speed rates, programmable speed graph

o Address range 1-9999

o Maximum 1 A engine output

o Load control (can be enabled/disabled via the CV register)

o 20 kHz motor PWM frequency

o 2+4 (NEM652) or 2+4 (21MTC) 2+7+3 (PLUX) pcs. short circuit protected func-

tion interface

o Analogue mode

o Asymmetric DCC sign perception (ABC mode)

o Permanent break distance in ABC mode

o RailCom

o Consist (multi-locomotive) operation

o FL, F1-F28 function handling

o Adjustable light intensity

o Shunting mode

o Acceleration, deceleration modes can be switched on and off

o Locomotive driver function

o Disconnecting function

o 3 or 28-point adjustable speed graph

o Different interfaces for the different standards

o Sound playing features:

o 4 - 8Ω speaker output

o D class sound terminal stage, 2,7Watt performance on 4 Ω

o 8 or 16 bit resolution, 22,05kHz sampling frequency

o 8 independent soundtracks played at the same time

o The speaker output is not short circuit protected!

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. If there is no reactor

coil between the motor and the decoder, do not leave the capacitor on the

output of the motor. Remove any capacitor between the two motor leads and

the frame,

o clean all the current collector skates and the wheels of the locomotive,

o run the motor starting from ~5-10V in neutral gear, while measuring the cur-

rent consumption. If it takes more than 200mA, check the state of the motor

brush and the commutator and if necessary sweep out the coal powder from

the gaps between the bites,

o check the light bulbs, if necessary change them into higher voltage ones. The

new bulbs should have at least 16V,

o check the insulations. In case of locomotives, where one of the poles of the

rail is the metal body itself it is important to check if the motor’s insulation is

adequate,

o check the condition of the engine in terms of running and lubrication.

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.

The standard length of the cable is 8 cm, but different cable lengths are available for indi-

vidual orders.

DigiSound-x.1 decoder with the new interface

Sizes: 11.2 mm x 24.0 mm x 3.2 mm

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. In this case connect the device the opposite way around.

Sizes: 11.2 mm x 24.0 mm x 3.2 mm

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

o Yellow: Rear light

o Green: AUX1 function output

o Red: Right track connection

o Grey: Left motor terminal

o White: Headlight

o Blue: Function interface. Common „+” pole

o Black: Left track connection

o Purple: AUX2 function output
