Can I add sound to a TMCC powered B?

That board is a motor driver board. No sound from that component! But yes, no reason you can't add sound with a ERR sound commander.

Thanks for the reply!

I probably should have been a little more detailed... I have a TMCC powered B, that uses everything below the shell from a Lionel set 6-24588, and looking at the parts list, I do not see where I can add stock Lionel RailSounds equipment.  With that said, I was wondering if I can just piggy back an ERR RailSounds Commander or Sounds Commander 2, onto the components already present in said B unit.

I say "I do not see where I can add stock Lionel RailSounds equipment", because on the PCB for a NYC Powered B unit, thought there were some slots for a RS Power board & Sounds board.

I also like the TMCC FTs, as well, because of the VCO:

With that said, can you offer any assistance on how to wire the ERR RS Commander, or Commander 2, to the existing electronics in the B units?  Both the NYC & Ex-PRR?

Thanks,

Mario

I don't see a motherboard listed in that parts list, what motherboard is in that unit?

FWIW, it's very easy to graft the ERR RailSounds Commander to most any installation, really all you need is serial data and power.  Obviously, serial data is on pin 24 of the R2LC, and the power is simply track power and frame ground.  Connect the speaker and away you go.  No VCO needed for the new single board ERR RS Commander.

I can check when I get home!

If you have the mother board shown you can just addendum power supply board and railsound 4 or 5 of your cboice. G

Thanks so much, I'm really enthused about doing this, as I'm having a fuel tank machined to fit a Tang Band speaker. Yes... those awesome speakers!

John, here's the picture of the TMCC board that's in there:

Any ideas on where to tap in?

thanks,

Mario

I think it's this one...

Here's how to find pin 24 of the R2LC.

Here's the connections to the RailSounds Commander harness.  You'll probably just cut the 4-pin plug off and wire them into the indicated places, the other two plugs go to the RSC.  I hope you know what to do with the speaker plug!

Since we know what the motherboard is, you could actually pop those pins out of the RSC cable and put them into an 7 pin connector in the right places and have a PnP installation.  I see 3rd Rail, GND, and Serial all on the connector on the left.  That's the 2.5mm JSC EH series connector, the same as the 4-pin connector on the RSC harness.

Sweet.  

One last question. 

Is there sound quality degredation between the factory RailSounds to the ERR RSC to the RSC2?

thanks!

Mario

Ok, I lied... more questions. 

For an unpowered B, can I also add sound?

And what about the Sharknose powered B:

Actually, the ERR RSC should have better sound than RS4 boards, and equal to the RS5 sounds.

What is in the unpowered B?  Typically an unpowered B won't have any electronics, so you'd have to add a TMCC receiver and the RSC.

Nope, no can do with anything currently available.  This is a Legacy setup, and the Legacy sound boards are not available without a trade-in of the old board.

With today's availability, you're out of luck adding Legacy sounds to anything.

This is the board in the unpowered B, it has lights and smoke, But there isn't a sensor for speed measuring; will it still notch?

Yes, the ERR RSC doesn't need or use the flywheel speed sensor.  If it did, it wouldn't work with plain TMCC.   It gets the data for the prime mover sounds from the serial data.

yay!

This is going to be expensive, I've got a lot of unpowered units to add sound to.

Thanks,

I suggest you add one and see how it works and if you're happy with the results.

Ha!

PS- I meant sound-less, not unpowered. 

Thanks!

Same advice applies, try it in one and see how you like the result.
