If I understand correctly....5.5 is the beginning of Legacy and used in early Legacy engines.  It can only be used in Legacy engines?

There are 2 chips on most boards.  What does each chip do?

Thanks

Dave

The chips are somewhat of a matched set.  Truthfully, while I"m not 100% sure, since the smaller one is labeled with the sound ID, I'm pretty sure it's the sound files.  The larger one with the same numbering is used with multiple sound file chips, so I suspect that's the logic that selects what sound file to play based on either the serial data (command) or track offset voltage (conventional)

Yes, while you may get some function in a TMCC locomotive with a RS 5.5 or 6.0 board, they will only work properly in a Legacy environment.

RailSounds 5.5 is a 9-bit system for Legacy. As John mentioned above, you may get some sporadic function with a 5.5 board in the TMCC environment (and maybe conventional too), but basically, it's dedicated to Legacy.

The large PIC chip is the microprocessor that contains the instructions/code for operation. The smaller ROM chip holds the sound snippets.

Thank You  John

So if one suspected a problem with the sound chip, it seems you have to buy the entire board?

I've looked on Lionel's site and I could not find just the chips.  Maybe I was not looking in the right place?

Dave

The chips are usually good or bad, very rarely are they "problematic." What issues are you seeing, which engine are we talking about, and what are the labels on each chip?

Thanks John/TRW for your responses.

This is Lionel 6-28273 CSX - Cab 3329.  It is from an Intermodal Set.  I bought the engine a few months ago (not the set) brand new in the box.  Circa 2007.  Sorry, I don't have the set #.

It worked well briefly and very shortly thereafter, the radio board went and I replaced it.  All was fine except I lost some sounds.  Two for sure are the Brake release sounds when I use my Legacy controller to change direction and brake squeal is also gone.  Runs and sounds great otherwise.  I can live with this .....I am just curious as to why this happened. ?   I've included pics as requested (the CS markings on the chips are mine).  I did pull the chips (with chip puller) and reseated but to no avail.  Early Legacy 5.5.  I replaced the smoke resistor with an 8 ohm one.  It also has that annoying issue of the smoke unit not shutting off when the engine is shut down....common as I understand it to this era of early Legacy units.

I did do a full reset, code AUX 1 - 2, also to no avail.

This unit is road specific and the boards are not available from Lionel.  Be happy to buy a used one or another SD 40-2 board....road specific not necessary if anyone might have one.

Thanks Dave

I think Rudy @Railsounds may be the guy to answer this question, what he doesn't know about the sound system probably isn't worth knowing.   I find it difficult to believe that some sounds are gone and not others, I've never seen a failure like that.

John,  I purchased a used legacy/Bluetooth Long Island E6 Atlantic locomotive the other day.  I knew the tender had sound issues before buying it.  I have bell and whistle sounds,  but no chugging and Tower com/crew talk.  I placed a different, but same type of tender on the locomotive and all works great.  Without anyway of really testing the rail sounds lite card,  I can only assume that the card is bad.

try putting the suspect tender on the track without the locomotive in front of it. apply track power and see if you hear any background sounds. if yes, the previous owner intentionally or inadvertently used the blend feature and turned the background sounds down all the way off.

What's the "blend feature" Rudy?  Are you talking about the AUX1-VOL keystrokes or something else? 

Just bell and whistle sounds like the RS/SS switch is in the wrong position.

Hi Rudy,

I tried that in conventional and nothing happened,  however,  I still can activate the bell and whistle from the transformer.  Also Rudy,  every now and then while running the loco in legacy mode,  you’ll hear a quick burst of chugging followed by silence.

regarding the missing brake sound, since the radio was replaced and then the problem started, this is most likely a system issue and mismatched firmware between radio and sound board. try setting up your cab2 and this engine as tmcc or cab1 mode and see if the brake plays then. legacy brake is a different command then tmcc brake. the radio may not be passing the correct command.

Thanks Rudy for your response.

The plot gets more interesting. 

50% of the problem was solved with your advice.  In TMCC and or CAB1....I got the air release sounds when changing directions.  Back to Legacy....no sounds in this area.

However, no brake squeal sounds in TMCC - CAB 1 or Legacy.

Two pics attached...one is from Lionel's parts site for this engine (Radio Board),  the second is the new one (Radio Board)  I had on hand and installed......

Thanks Dave

Rudy, was there ever an index of which processor chips went with which sound chips for the older RS boards?  I know that there isn't always a 1:1 match, at least for the RS4 stuff.  I see the same processor chip used with a number of different sound chips.  Just wondered what the difference is and how they were mapped.

I completed the same test with the same results (as per above info) using a different Lionel R4LC - SO3.

Thanks Gents for your help.....I guess for now it will remain a mystery.
