TMCC ASC X TMCC SC2 what to buy? (for Legacy)

quote:

To connect to ASC in Legacy I need to buy cable(6-14191)that is correct?

I would recommend the ASC's and you will need the cable to connect it to your Legacy base.

Others may weigh in on this and recommend the SC2's. The only advantage I could see is the SC2's can control both switches and accessories with the same unit. If you only plan to have a few switches on your layout and a couple of accessories go with the SC2.

If on the other hand if you intend to have an expansive layout with a number of switches and accessories go with the ASC's. You could use one to control switches and another to control accessories.

I'm curious why you can't use output one of the SC-2 for a Fastrack switch. Where did you see this caution?

Since there are six outputs, one would assume that even without output one, you could control 5 switches.

I have in my layout:

- 12 Fastrack Switchs;
- 03 Fastrack Uncoupling;
- 01 Atlas Turntable

What will I need to buy?

Thanks,

You are correct, I had not understood that all terminals can control switches

You can control Fastrack switches with all 6 outputs. But in order to do this, use the number 1 position, you must cut the trace connected between the power connector on the left bottom to the number 1 terminal. This trace is located directly above the U terminal of the two terminal power connector. This has been posted time and again in this forum and is a great fix.
Also, I found that the TMCC triggering of the SC-2s works better if the U terminal of it is common with the track U terminal...in case you are using separate supplies.

Chuck, I just get a file of Lionel with these two pictures instructions to do what you said!

To use the other two outputs I connect the wires in the same position of the terminals to switch?

Another question can also control my Atlas turntable with the SC-2?

Thank you for your help!

I'm assuming you would be using separate supplies with Fastrack switches? Is it possible to use track power with those, I sensed that it was not.

From what I read about the ASC, it only handles four switches, so I'd think for switches the SC-2 would be a better choice.

It's too bad that the SC-1 is problematic with Fastrack switches, they are dirt cheap compared to either of the other two options. I've used them with success for 022 switches, they work great.

Separate supply or track supply, both work fine.

The manual explains how to do accessories. If you are going to do accessories, then the first four positions do switches and the last two positions do accessories. OR...you can program it to do all 6 switches. OR...you can program it to do all 6 accessories.
The only thing that is not in the manual is cutting the trace just above the power U terminal so that you can use a Fastrack switch in the first position. Of course using a Fastrack switch there and cutting the trace means you have to supply power using the two terminals or with the wall wart supplied. As I have said, the wall wart method didn't work well for me. A separate supply was better and connecting the U terminal to the U terminal of the track supply.

With having a few ASC's having the cable hooking to Legacy. Would one run into the power problem like with TPC's?

Probably since they have optocoupled inputs.

My new MANCO Booster will drive quite a few wired accessories.

Yes, for all accessories and fastrack switches I'm using separate supplies !

I`ll buy an SC-2 to begin with 5 switches and turntable !

Just curious, what was the issue with the wall-wart? I suspect that simply providing track power is easier, and in the command environment, it should always be there.

I should clarify, it wasn't the wall wart as such, but finding that the command worked better with the U terminal connected to the track U. So I just added the supply.

You'll only be able to do 4 switches plus 2 accessories with one SC-2. I would get two SC-2s and program one for 6 switches, and the other one either for 4 switches and two acc or for all 6 acc.

Chuck,

If I have 12 switches, 3 unclounping, a turntable so I'll need to buy 3 sc-2?

Are two SC-2 to the switches and the other for the rest, am I correct?

Thank you,
Leandro ...

Yes you could program 2 for switches, cut the traces as I did, and the third as 6
accessories

Thanks, just wondered what the issue was.

Still got a question!

How do I activate the Atlas Turntable, because as he turn to one side and
to another does not know how I will make the connection with the SC-2?

Has anyone done this or know how to do?

Thank you,
Leandro ...

You may have to use two channels, one for each direction.
