Lionel SC2 and ASC

The SC-2 doesn't connect using the serial link, it receives the RF signal like a locomotive.  The ASC units would be daisy-chained from the serial port.

The more I look into what I need the more I get confused. I need advice so that I don’t start doing things 2 or 3 times.

Right now I have an old ZW, Legacy Control System, and a SC2 for 6 switches. This all works fine. This is all on Super O track.

I am now adding 2 more switches, 5 uncoupling sections, and 5 spurs that I can turn the power off to the track. To do this what else will I need or what do I need to change?

Thanks

Steve

I actually like the SC-2 for switches and track power control, it has plenty of capacity for that.  You can also control uncoupling tracks, see page 35 of the SC-2 manual.  The great thing about the SC-2 is they're easy to install, no serial cables back to the base.  The relays in the SC-2 are rated at 15 amps, plenty to do the stuff you're considering.

I think I'd add three more SC-2's, one for the extra switches, and the other two to handle uncoupling and the sidings.  This also gives you room for a little expansion.

Should each SC2 handle the same things or could 2 switches and a couple of uncouplings be on a single SC2?

Page 22 of the  SC-2 Manual  allows for all (6) terminals to be switches

Page 23 of the  SC-2 Manual  allows for all (6) terminals to be accessory.

Page 24 of the  SC-2 Manual  shows a chart including the (4) switch/ (2) accessory.

6 switches. Original.    (1) SC-2

(1) Additional switch. (1) SC-2

5 uncoupling tracks  Program for Accessory and momentary  (1) SC-2

5 track spurs  Program on/off.   Programmed for Accessory and on/off  (1) SC-2 

To confirm what John said.  

Thanks John and Mike. That is what I was afraid of. Now off to Sidetrackhobbies to get myself some Christmas presents.

I was trying to keep it simple and use dedicated SC-2's for each task.  Also, since you would be using every output, there's no room for expansion.  You can combine as Mike has detailed, but I think that makes things a bit more complex.

Interesting to note that You can do (12) accessories.  (6) to Aux1 and (6) to Aux2  Standard programming with (4) switches and (2) accessories also allows for (4) accessories, (2) to Aux1 and (2) to Aux2. 

Well, sort of Mike.  If you have some that are momentary and some that are on/off, they could share one channel, that's true. 

I now have two SC2 working switches. One SC2 working the uncoupling track. When I hook up the last SC two to power the sidetracks I am having a problem. When I applied power to one of the tracks I get a fluttering. 

I am running power from the main track to power the SC2. Each side track has a wire from the curve accessory terminal  running to the power rail. 

Any ideas as to what I am doing wrong?
