The 21 MTC adapter board 2 is also suitable for digitising a loco without interface. It is very helpful, if you do not intend to wire the decoder freely or if you wish to use more than four function outputs on your LokPilot or LokSound decoder. This adapter board simulates the typcial size and shape of Märklin® 6090x-decoders and can be installed in every suitable position.
Decoders with 21MTC connectors (ESU LokPilot or LokSound favoured) are simply plugged onto the adapter board.
On the output side, the adapter offers already soldered cables (appr. 20cm length) for all contacts needed. Thus the wiring of your loco is child´s play. There are amplifiers (appr. 250mA each) for function AUX3 and AUX4 (the decoder´s logical outputs) so that ESU decoders have up to 6 available physical function outputs.
