Thank you for choosing the product developed and manufactured 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 has been doubled to diminish the risk of con-
tact problems.
- DigiSound-x.1 (8-pin NEM652) decoder has 2 additional function outputs.
- The height of the DigiSound-x.1 decoder has decreased: 11.2 * 24.0 * 3.2 mm.
- The size of the DigiSound-4.5 decoder (Plux22) has been significantly reduced:
15.1 * 25.4 * 4 mm.
- The DigiSound-4.5 decoder has 7 pcs. of function outputs on top of the 2 lighting
outputs. The TTL GPIO points of the PluX22 interface, can be the CV register’s pro-
grammable output and input (AUX8 - AUX10).
- The DigiSound-4.5 decoder has SUSI interface for communicating with external de-
vices (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 depend-
ing on the resolution.
- The DigiSound-5.x 128Mbit (16MB) audio memory can store 6-12 mins of audio de-
pending 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 channel, correcting “csi-hu” timing.
- Correcting sound sample loop checking 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.
Changes in v38 software (19.10.2021.):
- Running after Z21 emergency stop error- resolved.
Changes in v39 software (29.05.2022.):
- Heavy vehicle acceleration cannot be adjusted - resolved.
Changes in v40 software (20.10.2022.):
- Sound function button mapping by writing CV registers.
- SUSI function button mapping by writing CV registers.
- Decoder needs to be reset after update (CV8=0)! Saved CV settings must not be re-
loaded (CV8=8).
Changes in v41 software (24.11.2022.):
- Slowdown of motor output short circuit detection.

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. 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 ade-
quate,
o check the condition of the engine in terms of running and lubrication.
The decoder is available with several, different standard specific connectors.

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-5.1 decoder with outputs for extra functions
Sizes: 11.2 mm x 24.0 mm x 3.2 mm
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. In this case connect the device the opposite way around.
Sizes: 11.2 mm x 24.0 mm x 3.2 mm
10
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
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
