The closest two only deal with Digitrax. So no not really I guess not enough demand.

No I didn't. I'm hoping that they will, but if they don't I will have to save my money and purchase them.

Yes - and I presume it does nothing if you only feed voltage into pins 1 and 2.
If you also close the push button connections, it might change its position each time you apply power to pins 1 and 2.

Advantage: you can control 12 Cobalt Digital with a single LS150.
Disadvantage: you cannot set a turnout to straight or round, you just can toggle its position (so you cannot use turnouts in routes).

But maybe I missed an important detail ...

BTW: 15 V AC has a peak voltage of 15 * 1.41 = 21 V. Even with the diodes this may be too much for the Cobalt digital if it uses a buffer capacitor inside (and since it was made for DCC, I presume there is such a capacitor).
The diodes reduce the effective voltage and light bulbs or purely analogue motors could be used, but they do not change the peak voltage and digital devices with a rectifier and buffer capacitor might get damaged by the peak voltage.

No built-in decoder with your tortoise motors. It's like comparing analogue loco with digital loco.

If you connect analog power to the decoder...do you think it´s digital power and function???
No...it´s still analog power.
Decoder in Cobalt motor is react after power consumption.
Just feed analog power and it works by after analog power.
Use LS150 and you have analog power feeding to the Cobalt motor with or without decoder in the motor.

Well, it's analogue power that is fed into a digital decoder - and it's up to the digital decoder how much of the power goes to the motor.

You have non-digital non-Cobalt turnout motors and have no problems with 15 V AC plus diodes.
Quinton has digital Cobalt turnout motors.

IMHO it can't hurt to ask DCCconcepts whether the proposed connection (LS150 plus transformer 15 V AC) might work with Cobalt digital.

15 V AC plus diode means: no power during 8.33 ms, then a half sine wave for 8.33 ms reaching a voltage of 21 V, then no power for 8.33 ms and so forth.
This kind of voltage is OK for analogue motors as the few milliseconds of over-voltage won't do harm - and then there is time to cool down again.
So there should be no problem if it were standard (non-digital) Cobalt motors.

I'm a noob with respect to tortoise motors, but I would not try this if it were my Cobalt motors.
You are the tortoise motor guru with a whole lot of expertise and you are so dang sure it will work that I will stop here.

In all accessory digital decoder there is warranty.
Tortoise offers to customer 9 years warranty and that included by use with half wave voltage too.
This accessory decoder in Cobalt motor does have protection against overload and short circuit.
It´s harmful for the half wave voltage too since Cobalt shows result too by use Cobalt motor.
It has same result like Tortoise motor by use in analog power.
Just connect 12VDC to the decoder and it´s react of power consumption.
Since it send 12VDC power to the motor...it should accept with half wave voltage too.

I suggest TS shall first try just one motor and test how it was.

There is one i don´t understand...TS is not alone to have problem by use Cobalt digital motor in DCC motion...so what exactly is the problem in the accessory decoder?
You see...even other customer who use other digital system has same problem so it´s not CS2 default!!!
I think this is the last comments from me...so i wish Quinton all luck by test.
If bad luck with Cobalt digital motor...buy Tortoise motor instead...you live in USA where almost every body use this model!!!

Ciao

You wrote in your #95 post:"remove the decoder".
But Quinton has already said that it is NOT possible to remove the decoder of the Cobalt Digital !
Thanks for your very valuable advice!

fred

Why???
It works with 12VDC too by not remove decoder.
So what about to use LS150...?
LS150 leaves out analog power too...but instead 15VAC.
But if Quinton use 2 diodes it protect motor.

There is no need to fight about it. What I need is a solution without the LS150. When I get the LS150 we will know if it works, or not.

As far as the LS150 goes is there a particular way the B & O wires attach to the LS150. In other words does the B wire go the K connector, and the O wire to the J connector or vise versa?

Thanks

Half wave voltage replaces the patch with 12VDC.

We are not fighting.

One user says you can easily use the Cobalt motor with the LS150 if you remove the built-in decoder from the Cobalt digital. True (but so far it seems impossible to remove the internal decoder).

It's a simple fact that 15 V AC has an effective voltage of 15 V (by definition) and a peak voltage of 21.15 V (assuming it's a sine wave (and there should be a sine wave coming from the wall outlet and hence there should be sine wave coming out of the transformer)).
When using diodes to clip off a half wave, you get an effective voltage of 7.5 V (suitable for Cobalt digital) and a peak voltage of 21.15 V (above the maximum of 16.5 V specified for the Cobalt digital).

No fighting about simple facts. But since we do not know the internal wiring of the Cobalt digital, we can only speculate whether a Cobalt digital with decoder can safely be used with an LS150 and 15 V AC clipped with a diode (effective voltage is OK, but peak voltage is too high - and typically decoders use full rectifiers and capacitors inside, so typically it's the peak voltage that has to be taken into account when feeding power to a decoder - when powering light bulbs or stupid motors (without semiconductors), it's the effective voltage that counts).

Since a Cobalt digital used in analogue mode can only toggle its position, but cannot be told to go straight or go round, it makes IMHO no sense to use a Cobalt digital as is with another external decoder. Even if it should work, it could not be used reliably for routes or automatic operations.

I still think a Cobalt digital as is should work with the CS2 (especially since it is documented to work with ECoS a.k.a. CS1reloaded). But it seems there are no Cobalt digital users around here.
A step by step description of what you are doing to program the Cobalt might help a CS2 expert to identify what is missing.
Or a step by step description from a CS2 export on how to program DCC decoders might help you to identify what is missing.
Maybe the fault is with the wiring - you didn't show pictures or diagrams yet, did you?
It's a long chain - and if it doesn't work there is a fault somewhere in the chain and all elements of the chain have to be checked.

There was a similar problem reported against Viessmann decoders - those decoders also learn their address automatically. It worked in the end.
Discussed in this thread.

No fighting. Anders is your leader.

This how I have it wired, and trying to program excerpted from post #12.

I have the O wire going into the DCC track hole (1) of the motor. I have the B wire going into the power hole (2) of the motor. The switch on the motor is on set. On the keyboard screen I click the wrench. The screen turns blue. I click on turnout 1. I select DCC. I select left turnout for the type. I leave the name at 1. I leave the switching duration at 250. I then click the green check. I then click the green arrow. It then asks me if I want to stop the operation of the locos. I click the green check. It then tells me I can program the solenoid after waiting a second. I click the green check. It then brings me back to the keyboard screen. I switch the motor back to run.

I don't think pictures would help just two wires going to a motor.

Since Cobalt motor is equal same as Tortoise motor you can use 12VDC or half wave voltage.

At this point I would set the decoder to the SET position and toggle the turnout on the CS2 keyboard screen a few times and then go back to RUN. And then toggle the turnout again and again to see if the Cobalt reacts.

If it doesn't work, reboot the CS2, go to the keyboard page and try again: SET, toggle, RUN, toggle (at least twice).

Re "It then tells me I can program the solenoid after waiting a second."
I presume this message is meaningless as the Cobalt does not use "normal" programming.

It shouldn't make a difference whether 0 connects to 1 or 2. But it can't hurt to try it the other way around if it doesn't work yet.

If I understand correctly, you have more than one Cobalt. Did you try only one of them or did you test a few?

Feeding analogue power into an analogue motor is one thing, feeding analogue power into a decoder that is connected to an analogue motor is a completely different situation.

Blue transformers are not harmful to analogue locos. Blue transformers can be harmful to mfx locos used in analogue mode. Same constellation, same problem.
Same power and same motor - but the decoder makes the difference. You don't kill the motor, but you kill the decoder ...

Setting a bold font does not change physical facts: 15 V AC have a peak voltage of 20.15 V. With half wave, the effective voltage goes down to 7.5 V but the peak voltage remains at 20.15 V. This voltage could be harmful to the decoder inside the Cobalt digital.

You didn't answer how to connect LS150 and Cobalt digital without removing the buit-in decoder from the Cobalt.

The winner is Tom. I couldn't get the LS150 to work with the Digital Cobalt. I purchased a plain Cobalt with the LS150 to test that setup, and it works fine.

Working as far as switching, but the straight motor is not setup like the digital. I had my push buttons, and signals wired into the digital. The plain doesn't seem to be setup that way. So still not working. Why is nothing easy!?!? Have to get the digital to work with the CS2, or rewire everything to get the push buttons, and signals to work.

An old thread I know but... I just bought a few Cobalt IP's without checking this thread first... I tried a lot of things, including the recommendations here, but I didn't manage to get the CS2 and the Cobalt to work in DCC.

Then I tried to program the Cobalt from iTrain instead. I followed the instructions and it took about a minute per Cobalt to get them working with an address of choice. The good news was that after I programmed them they could be steered from the CS2 without any issues and as I had tried to program from the CS2 all the configs were already in place.

Thought I post it here in case anyone else is interested in these switch motors, they seems very convenient I must say. Will mount them during the weekend.
