A quick question regarding this decoder i have looked at the manual but did not notice anything regarding this.
Can you attach 2 cobalt classics to 1 terminal on the AD-8fx ? Obviously the the 2 points would have the same DCC address but in a crossover track situation the 2 points would only switch at the same time anyway.

Is there a power consumption reason why this could not be done?

many thanks

Yes, you can do that no problem - up to 4 actually.

Its a great ability that we added so some EU brands could be used (they usually have quite high current needs). You cannot so this with any "other brands" equivalent product!

Thanks Ahjay
Thats useful to know i do have a few crossover sets i will use that facility. That is going to be helpful with what i am doing at the moment.
Thinking on when you have passing loops you could employ the same principle.

Hi Brian, I've just put a passing loop on the gasworks branch so the shunter can do a runaround and push the coal waggons into the retort house siding.  I put both Cobalt SS points motors onto the same channel of the control unit so they operate on the one command.  Different set up but same principle being used.

Exactly Richard i have just added 2 passing loops to the area under my window on the layout for operational reasons as this bit wont really be scenic and the passing loops it would be daft not to operate both entry and exit points at the same time thus using only the one dcc address and only 1 accessory address. With the answer yesterday the AD_8fx can handle up to 4 cobalts at the same time i went down KMRC yesterday afternoon and bought another AD_8FX and 12 more cobalt classics plus the crossover sets i have on the layout will be converted to cobalts im up to 28 cobalts now

Another question regarding the AD_8FX if i could please.  I have 2 of these to install now and i was going through the instruction manual and came across the bit regarding the IO or FB connection its states IO or FB is a 5 volt computer IO("in/out")or feedback output.
Now i use a number of S88 feedbacks and Ecos detectors with my Ecos now is the statement above saying the AD_8FX acts as a feedback in some way if so how does the feedback connect to the system ? Or am i misunderstanding what is being said.

many thanks

All feedback devices simply report a connection as being high or low (on or off). How it connects will depend on the device it connects to. You sould normally connect it to the same place a detector is connected to, because the IO will look like a detector to the interface device..

Thanks Ahjay i will need to look at this more in depth as the S88 units connect to the s88 bus on the Ecos and the Ecos detectors connect to their own round pin plug connection on the Ecos. Whether the feedback on the AD-8fx can be utilised or connected to perhaps give state of the point motor (left or right position) i will have to look into an of course where it would actually connect to. This would only be a bonus and would not be the end of the world if it cant be utilised. 

many thanks

I am sure it can be... Just a case of getting the two wires to the right place. I will see if we can find a diagram as I know we have done it.

Thanks Ahjay be useful for people like myself who use feedbacks if they can easily utilise the facility on the decoder another selling point for the decoder.

many thanks

Ok really this is a dumbarse question but im pretty sure i have got this right but i thought i would just check.

I have some AD_8FX decoders and i am driving Cobalt Omega Classic turnout motors.

Now i am going to have to power these decoders from the DCC bus and  is set to around 16/17 volts on the transformer.
Firstly i assume from the manual the AD_8FX can accept a varying DCC bus power dependant on scale being used on?
My main question is on the Cobalt Omega classic when you connect your cobalt to the AD_8FX do you still have to switch the switch over from the 6-12volts  to the 12-18 volts or does the AD_8FX change the voltage before its delivered to the Cobalt?
I assume you need to switch it to the 12-18 volts but i thought i would just check

many thanks

Thanks Ahjay for confirming what i thought it would be. popped into KMRC and picked up another 6 pack of cobalts this morning more work😃
