First problem I had with wiring up the MSE servo unit to drive the signal was that of power supply. My Accessory power bus on Summat Colliery is driven by a laptop psu and whacks out 18v DC, great for supplying CDU units but likely to fry the controller box that needs 12v DC.
Now, the MERG pulsed accessory decoder boards I use also have an option of an on-board 12v regulated supply to drive small steady state devices. These parts are optional in the build, but thankfully I saw fit to
