Grateful,if you could let me know how to program the MX644D to convert it to an MX644C Thanks Mike

Tony, thanks for your reply. I think that the transistors are there to switch on the halos via logic outputs from the decoder, and that the pcb is wired for ESU decoders such as yours or the Loksound V4. A Zimo 644D will only drive the halos if the transistors are bypassed as described by John Gymer of YouChoos. Not sure I want to go this route; your experience is pointing me to ESU! Anyone from Dapol care to comment!

Interested to know if you have looked at the circuit board. The enamelled wire has gone and diodes on the halo circuits have been replaced by transistors. I have tried a Zimo 644D (without any modifications to the wiring) and it will not switch on the halos.

I have recently purchased this system and am reasonably pleased with it. The Apple based app seems to be a better than the Android one. The route setting via photographs is a particularly useful aspect, however I have totally failed to persuade a Train -Tech 3 aspect colour light signal to work with the app. The signal works fine with two addresses using a MultiMaus. I have tried every possible configuration with the track settings to no effect. Any hints or tips appreciated! Mike066
