Hello.
I've searched through past posts, and can't seem to find an answer.
Hopefully someone can help me with some questions.

I'm setting up a layout with CS2 60215 software V4.3.0 (11) and a 6021 controller through a 6021 connect #3935 Ver 1.
I'm new to the CS2. I've been using the 6021/6036 and 6040s for a couple years now.

I have entered locs into the CS2, and then gone to setup and listed them to the 6021. I did the update (blue down arrow)
and then green check mark.
The 6021 won't control them until I power off everything, and then repower.

Is this correct or is there a problem?

Waiting for CS2 to restart every time is surely cutting into my track time.

I'm also looking for some better info or video explaining the procedures regarding the memory. Is there anything out
there better than the Marklin manual?

Thanks in advance.
Will

I've tried 2 more locs, one with a msd/3 and the other has a 60906 decoder.
In both cases, unless I rebooted the entire system, the 6021 would not take control.

I've been reading many posts here and yet to find a like situation. What I have read
many times is reports of CS2 being frozen at start up.

That has me worried as I have many locs to load into the system and I am starting
to feel like I'm playing Russian Roulette.

Hi Jean.
Thanks for your response.
I do have the CS2 and 6021 plugged into the same switched power strip.
Yes, I agree it should be a seamless transfer as it is with the MS2 I have connected to the same CS2.

I do have a spare 6021 which I will try today.
Thanks
Will

My Marklin dealer and I communicated with Marklin Digital support on here is the answer.

>> I have limited experience with the 6021/CS2, but I know that it is buggy.

I do not know what a #3935V1 is. The 6021 should be connected with a “Connect 6021” (6028). Then, I believe, all that needs to be done is to input the default address of a locomotive into the 6021 and run the locomotive.

The 6021 becomes a secondary device at this point and the commands that are sent from the 6021are repeated by the CS2.

I think 😉<<

Pretty disappointing answer.

So I re re re read the 6021 connect manual and found a note at bottom right.

The note is under the "remove connect 6021" instructions, but I suppose it might be meant to apply to all
operations prior to that as well? I guess that's what I'll live with, which is better than it being buggy.

Hi Will,

I have a cs3 and a couple of 6021’s. if I get some spare time next week I will try them out and see how they go.
The last time I used a 60128 to utilise my 6021 was with a cs2, and that was a number of years ago, so there have been many software changes since then.

Potential problems I can imagine are faulty hardware (unlikely in an 6021)
User induced error (usually as a result of Marklin hopeless manuals)
Software upgrades from marklin have improved things so much that they don’t work properly.

Anyway, if I get a chance I’ll try to do some tests.

Cheers….

Mike

Thank you for the responses.

I should share what I'm working on. My layout is 10m x 6m, "E" shaped.
On the center leg of the "E" is the central command location with 6021 w/transfo, 6036, 4 x 6040 keyboard
3 x 6017 boosters w/transfo. Top leg has 6036, and 1 keyboard. Lower leg has 2 x 6036, and 3 keyboards.
The 3 stations are connected by RJ-45 shielded cables and IEK connectors.
This was all functioning, and then I acquired a CS2 at a good price. I did so for
the obvious ease of loco control/functions reasons, and ability to create a multi unit locos.

I like the ease of access to the turnouts with the 6040 keyboards compared to the keyboard of the CS2.
That is why I decided to get a Connect 6021.

As I said earlier, I also want to get proficient with the memory
of the CS2. Still looking for useful instructions for that.

Presently I have a test oval w/siding set up with the CS2, Connect 6021, 6021, MS2, and a keyboard. I wanted
to educate myself somewhat before introducing the CS2 to the layout.

Jean, I have had the odd connection problem with the 6021 etc units, but eventually get them nailed down.

hahaha.
No one is immune to that I guess.
I have done the loco adding process about 20 times now with the same results, except for that one loco
with defective decoder. I must always reboot the system and then all is good with the Connect 6021/6021.
So, I don't know if I'm doing it wrong from the manual, because I'm just doing it. I can live with it as it is
happening as long as CS2 keeps working.

marklinist5999 - Thanks for the info, I'll look at the webinar. The CS2 can handle M83 and 84 as well I believe, yes?
By the time I get to wanting those, we'll probably be looking at CS4.

Thanks guys.
