Adding a CC-M

The red arrow is appropriately colored, it you connect there you may well get flames.  You will also do a lot of damage as that's track power!

Try the blue arrow, it's the serial data.

The fact that you spent who knows how much of your time reading 500 comments (!!) on how to install these little electronic boards, and with manufacturer's instructions and a bunch more time still couldn't figure out how to complete the installation of this thing, is not exactly reassuring to those of us who might consider trying to install a CCM!   I wonder how many folks end up frying boards hooking up the wrong wires?

More than you'd like to imagine.

In all fairness it really isn’t that difficult.  Asking questions is a good idea and GRJ has probably answered so many of mine he’s about sick of me.

The only trouble I ran into was that I have an R2LC07 in my units.  But after wiring up GRJ’s improved serial buffer and a little extra debugging, I won’t even need to buy an R4LC08!

It seems the issue with the R2LC07 is the board electronics and NOT the code.  The serial data output driver in that board is just really, really, REALLY weak.

Wouldn't be the first time I've had flames.  For real.   Smoke means you screwed up a little.  Flames - try another hobby, perhaps.  I couldn't be in this one without this forum.  If it ever ended, I would have to collect stamps or something.

It was all the talk of serial data buffers and the likes of that that had me wondering, and not knowing the numbering of the pins.  So I assume that in this particular case all I need to do is follow the instructions for the rest of it, and tap the "blue" pin for the data input to the CMM.  No buffering or other strange (to me) electronic machinations. Correct?

Best laugh I've had all day. Thanks!

As long as you don’t have an R2LC07, correct.

The board says R2LC C, so I must have lucked out.  Thanks people, for the usual help.  I'll post again when I make a mistake on the J4 Plug and burn down the entire layout.  Or if it's the house and the computer is gone, I won't.  Thanks again.

There is only one wire to hook up. The rest are all in plugs that just... plug in.

Having retired from a 43 year career as a electronics technician ending as a network engineer, I know sometimes the simplest thing can be most confusing.  Bucky, you did the right thing and asked before making the connection!!  I'm glad you are taking comments in stride.

In the telecom business, we used to say 'how can keeping 4 wires straight for a business data circuit be so confusing'.  On the other hand, There is nothing like connecting the wrong wire and tripping a 500KV breaker in the substation!  Even sitting in the control house and the breaker way out in the switchyard, the sound was nearly deafening!  A second was when I dropped the end of a live high current wire on the steel grate floor in the power station.  That fraction of a second of blue light before the lights went out was interesting.

To add something, connector printed circuit solder pads for pin #1 are square instead of round for all the remaining pins. Best to ask, but look for the square pin pad as #1.

Nothing in this post's responses bothered me.  But since we are on the subject, "Taking things in stride" is a necessity on the forum.  Over the years it seems to be experiencing a gradual increase in snarky posts.  Some people posting that kind of thing think that putting in an emoji makes it okay.  It doesn't.  I suspect the member at which it is directed does not feel better because of a happy face.

I located the square pin pad!  Thank you again guys.  

CC-M may be simple in the end, but at the start the directions did leave me confused.         

I sure didn't notice the square pin pad, until Jack mentioned it.  I'll have to remember it since I will probably be doing some of these in the future.  My observation skills leave something to be desired.  My 5th grade teacher would be sad to know that since the one thing I remember about him from 55 years ago is that he was always telling us to 'observe'!    My very good grades in school and college never seemed to help me reading directions.  I always miss something.

I apologize if my reply hit the wrong way, it wasn't meant to.  I really was conveying the information requested, just figured I'd add a little humor with it.

Don’t feel alone Bucky, in the beginning, ..I’ve had to blow up a couple fellas in boxes on more than one occasion on ERR installs......Once you get the hang of it, you’ll be helping the next new guy on here.....gotta crawl before you can walk buddy!....At least you had the good sense to stop before you let the magic smoke out.....😉

It was perfectly fine. And I did laugh about the "red" wire.  My last comments, as I stated, did not mean to imply anything in this chain was snarky.  I meant it as something I have noticed in general on the forum.  Ninety-nine point eight percent of the time this is the best place in the world for model railroaders of any kind to "congregate" and ask questions.  (It used to be 99.9 %.)   Where else can one get so many responses to a question, even seemingly dumb ones, in which I specialize.

John, I apologize if MY comment hit the wrong way.  I was not talking about you at all.  You remain one of the greatest resources this hobby has, and you always respond helpfully to all, as do so many others.  Besides, I did put a happy face emoji in there.  Ha!

Bucky,

My initial response was not meant to demean your first attempt, but actually to calm the fears of others like breezinup about working on their locos.  You did the right thing for your wallet by asking - although anyone is free to learn the hard way as I have done many times myself, LOL.  You also did perfectly in identifying the two possible pins it could be, and the good pictures with arrows was a great way to convey the question.  Way better than a lot of other posts that are like, "I bought something and it's broke, pls halp."

I think you'll be very pleased with the results once you get it all buttoned up.  The CC-M is a great upgrade.

rplst8,

I really didn't think your responses were anything but helpful. Finding out the R2LC07 was not an issue for me makes the whole thing straightforward, as you said.  Solder a connection followed by plug and play.

For quite a while I had been thinking about the snarky comment deal; noticing it while reading posts from time to time.  It didn't have anything to do with this post.  Should have said something in a separate one if I  wanted to say anything.  I just didn't think it through enough to realize everyone might think it was directed at people here.  I sincerely apologize for that!  Not thinking things through enough is likely the reason I have to ask for help so often.   

Bucky,

I think all of us accept your apology, I certainly understand.  I also think most of us have thought from time to time, "why did that guy respond the way he did?  That wasn't nice of that guy."  I have mixed up comments that should have been directed elsewhere also, or kept to myself.  No harm done here as I see it.
