ERR Cruise Commander M sound issue

The wire at J4 pin 2 is not generally used. I've only soldered the J4 pin 1 wire to the pin shown on the R2LC board connector. Check to see if the A wire is connected to that pin on the R2LC board.

Thanks Chuck,

I initially had it soldered to the R2LC connector, as shown in the SD-60 install.  Probably best if I go back and trace connections just to confirm I have pin 1 tied in correctly.

Hi Bruce,  I recently installed one of these. I had the same questions regards J4.

As Chuck says pin 2 on J4 is rarely used,  in fact GRJ mentioned he had never used it. He's done a fair few of these installs so that was good enough for me.

Pin 1 on J4 goes to pin 24 on the RL2C connector.

Thanks Nick,

If you were like me, you tried saving the brand new R4LC in the Cruise Commander M kit by reusing the original R2LC.    My morning cup of coffee kicked my brain in gear as I recalled someone here having issues that were solved by installing the COMPLETE kit.  I just got back from swapping out the R2LC/R4LC components and everything is better than new.  My little Atlantic now has all the bells and whistles plus.  I'm astounded at how effortlessly it handles grades as compared to the wheel slipping it did without cruise.

The Cruise Commander M is a modular board for existing TMCC installations, it doesn't include the R4LC.

As others have said, I just wire Pin 1 of J4 to pin 24 of the R2LC socket, job done.  I've never used pin 2 of J4 on the CC-M board.

Note that there are some earlier CC-M boards that won't drive the wireless tether properly when installed, you need to either use the transistor booster circuit or replace it with a current board from ERR.  Specifically, you want the Cruise Commander M Kit - Steamer kit (all versions).

Yes I was wondering about the ref to the R2LC/R4LC. Are they different in a way that can affect having sounds or not? If not, could it be programming feature codes or not in the original attempt using the R2LC?

Well, the CC-M does sit on the serial data line, I suppose the R4LC might have a bit more drive and managed to drive the IR and the CC-M, not sure why else it would matter.

Right you are about the R4LC....it came with the regular CC 4.1 kit ordered at the same time.  It was actually saved from a previous upgrade.

The CCM upgrade in question didn't involve a wireless tether.  Whether it was a programming mix up on my part or differences in the R2LC / R4LC, who knows?  Currently it's buttoned up and working fine.

Hi just want to throw this out there, was your original a CO8 board?  I remember Jon(santefefan) asking me this when I bought mine and had problems just as he was going to Lionel.

Doug

  The removed one is R2LC06.

Bruce

I remember Jon saying it had to be CO8 or better. At least you have it working the way it should and that's what matters!

Doug

Correct, the C06 board is an issue, as Doug says, it's C08 or later boards that work with all the ERR stuff.
