Connection at LGB 55021 here we will show some connectivity options for several LGB Decoder. The following must be observed: You should have soldering skill and experience. Disable analogue mode in the decoder. You can solder the cables at bottomside to the corresponding pins. For damage caused by improper treatment, we assume no liability.

To protect against irritations regarding the correct connection of the gearbox to our electronics, here is a description about. Important supplement! The indicated cable colors may differ from the print on the gearbox! On some locomotives the gearboxes are installed 180 ° rotated. With Piko are completely different colors and assignments. Digital, the polarity on the track has an effect, but this can be changed by CV. So if you…

Ergänzung zur Firmware Version V3.5 Pulse simulation: The control of the pulse simulation has been fundamentally changed. The following CV’s now have the function described: CV 195 = Steam chuff per wheel rotation CV 196 = Clock setting on slow speed CV 197 = Clock setting on high speed You have following choices in CV 195: 1 = 4 Steam chuffs per wheel rotation 2 = 2 Steam chuffs per…

You ask us consistently, what is the best back-fitting for a loco. Remove the existing electronic completely, partial or remain it? Sadly we can’t give a global answer, while there exists to many versions. Although we will show you here an overview, which back-fitting type is the right one. First of all you have to check your available place in your loco. You don’t need a useful interface, when…

While we don’t know what technology is used, we can not give common hints for it. Maybe you can find a proper back-fitting plan for a special loco in our examples. 1.) Engraved “D” on bottom side of gear is marking a 4-pin-gear. Here are all 4 contacts for digitalization existent. Without “D” you have to rebuild. 2.) Old Interface for 6 pol. interface cable. The decoder will be…

Conversion of a 3-lead LGB gear box to digital operation Old LGB gear boxes feature 3 leads, one pin (marked WS) is connected to track power and one of the two motor connectors. For digital operation the motor connector must be separated from this pin. The pictures show a simple conversion for digital operation: open the gear box and remove the electric motor (note the direction) shorten the motor contact…

Before digitalization of a loco you have to select the right decoder. Manufacturer’s data of current draw are not available in most cases or it is not reasonably usable. So it make’s sense to build a small measuring equipment for each loco, to measure the current. You need: (see picture) A LGB-transformer with apr. 22V(alt. a power supply) A meter for current measurement (Multimeter or analog instrument) . A…

To control a switch automatically with a 1 channel switch decoder, following circuit can be used. You will need 2 track contacts, a 1 channel switch decoder and locomotives with mounted magnet on the gear side. Here is a diagram of how everything should be connected: In this combination, the switch is automatically moved into the correct position before leaving the reverse loop. Note the polarity of the contact…
