SmartDecoder 4.1
Description
This PIKO SmartDecoder 4.1 G is a compact, very powerful multi-protocol decoder. It can be used in DCC, Motorola® and mfx® digital systems and also runs in analogue operation with direct or
alternating voltage.
The respective operating mode is recognized automatically, but it can also be set manually. The load-controlled decoder works with a motor frequency of 18.75 kHz and is therefore suitable not only
for DC but also for bell-armature motors (e.g. Faulhaber, Maxon, Escap) up to to a continuous current consumption of 5 A. Short-term higher motor currents are well tolerated. Thanks to its large
energy storage, the decoder is ideal for use in garden railway vehicles, as it can buffer dirty rail sections very well.
The PIKO SmartDecoder 4.1 G is RailCom® and RailCom Plus® capable and can handle both ABC braking and ABC slow travel. The motor characteristic curve is set using the minimum, average
and maximum speed (simple characteristic curve), or via the extended characteristic curve with individual settings for 28 speed levels.
The decoder has two direction-dependent lighting outputs, as well as eleven additional special function outputs, three of which are equipped with logic levels.
It also offers four connections for standard model building servos. Decoder-internal processes can be called up automatically via the three inputs for reed contacts, for example. The maneuvering
gear with an extended slow travel range and the three possible acceleration and braking delays can be switched using function keys.

Installation and connection of the PIKO SmartDecoder 4.1 G
You can attach the decoder to a suitable location in your vehicle using the appropriate screws. When installing, ensure that you do not pinch or damage any cables
with the screw heads. When placing the module in the vehicle, make sure that there is no conductive connection anywhere. Connect the decoder as described in
Figure 1. Only use suitable cable material with a sufficient cross-section for cabling. When using the screw terminals, make sure the screwdriver is the right size
so that the screw terminals are not damaged. The assignment of the respective connections can be found in the following figures. The first commissioning should
take place on the programming track with the control center in programming mode. When reading or programming, very small currents usually flow that do not
damage the decoder in the event of a short circuit.
Special functions A1 to A11
The special function outputs A1 to A8 of the decoder are designed as a row of screw terminals on the right side of the decoder. The second connection for these
consumers is labeled U+ in the same terminal row in Figure 1.

ATTENTION: Soldering on the decoder and connecting electronic circuits should only be carried out by experienced specialists with the appropriate knowledge and appropriate tools. The warranty
does not apply to decoders that have been damaged due to improper handling.
