SProblem with ARC Pro and curved lane changers

The power supply may be managed in a different way to what you think.

 

A single lane should be able to power 6 cars in one lane with both power adapters connected. So in digital mode the power must be combined and not separate

Hi all, yes, this option C will be fine for up to the maximum number of cars i.e. 6.

This is not a problem because inside the ARC PRO the exact same drive circuit powers both lanes anyway (it’s just that the signal polarities have reversed for other reasons). For 4 or more cars you need two standard PSUs to be plugged in (as per Scalextric instructions).

Just to clarify a point of detail, way back when I first proposed option C, what I had in mind was exactly as per Blagard-01’s above diagram. However more recently I have been proposing an alternative way to implement Option C to achieve an identical ’electrical‘ effect - by simply cross wiring the rails of a single lane at the point where the dead spot is formed. I show this as the point marked X in my earier rough ‘tty‘ diagrams. This keeps the modification effort to one lane only. I know an updated diagram is required to add further clarity and I hope to share this tomorrow along with some nice photos the little red mini in action on curved lane changers!

I hope this helps...

once again fine for digital only

and needs removed for analog use ,

along with all the other problem pieces you have installed for digital play

wow a cool picture of 2 pieces of track on each side of arc pro , each having a dead spot on and x marking the crossover wires of each on the same lane, with the same results

impressive

So Dr_C the diagram below will also work DIGITAL ONLY without any of the limitations. For Analogue when the modified quarters are replaced all limitations on layout apply.

Note that the wiring to cross the dead spots is not the same on each quarter, one must be the mirror reversal of the other.

Many thanks blagard-01... diagram is perfect!

Hopefully top down photo attached below... underside wiring photo to follow...

DIGITAL MODE

Yes... with above two modified track pieces in place the ARC PRO performs in full DIGITAL mode as per the C7042 APB. All curved lane changers can remain in play whether modified or not!

ANALOG MODE

Then, with two modified track pieces swapped out for standard track, the ARC PRO performs in ANALOG mode as per the C7042 APB (except a fine point of detail that there is no function in the ARC PRO to reverse the direction of travel). Howver, in this mode curved lane changers may only be kept in play if they have at least been snipped using the standard digital to analog mod. This is precisely the same requirement when using curved lane changers with the C7042 APB in analog mode.

I can confirm all of the above (I.e. Both digital and analog modes) have been tested at track level and also using a digital multimeter. It's great to see curved lane changers working perfectly with my shinny new ARC PRO. All good!

Modification front and back then shown in use with the ARC PRO... in FULL digital mode of course!!! :-)
