Can the Cab2 talk to the Base1L

Sounds like a question for Lionel, I don't remember if they said that will work or not.

Yes that sounds like a Lionel Question. The comm frequency wouldn't be an issue but not sure how the two handle engine IDs or what would happen if yon sent a Legacy command to the 1L base that the Cab1L handheld doesn't support

I seem to recall hearing that the CAB-1L would talk to a Legacy base, though I wouldn't take that to the bank without confirming it.  I just have my doubts about going the other way.

It does John. You are correct.

Will the CAB 1-L and the new Legacy base have the module slots for software upgrades or will they be "frozen" in time with whatever version is released with them?

Going back to the original posters question I suspect that even if the CAB-2 can communicate with the new base he will only be able to have one base active in the house at any one time, aka the main layout OR the Christmas layout, not both.

Based on a number of posts we've seen with signals jumping to test setups not connected to anything else his Christmas layout may already be capable of Command operation without another base.  The only problem might be the distance between the CAB-2 and the Legacy base.

This was answered before.  I looked to find it.  Maybe it was at the LUG meeting.

The simple answer is no.  There is no data base in the Cab1L for the Cab 2 to connect to.  Whether it can "talk" in a dumb down mode (TMCC or CAB1) I doubt it.  I think the Cab2 relies on the base for too much of it's operation.

It has been advertised that the Cab1L will communicate with a Legacy base though.

Although I have no facts upon which to base this, I would suspect that the base unit may be able to be upgraded in the future via the serial port connection. The remote is a much simpler device than the CAB-2, and I would suspect that there is little that could be 'upgraded' via software. 

Yes...no...maybe,  no facts but....hey this is the dcs/legacy/tmcc forum we are suppose to be the facts guys:-). Just teasing, but what is the correct answer?  Can some one test it? G

Not without a CAB-1L.  I'd be glad to receive a review model to do the testing.

Me too! and the LCS Wifi module.  I thought I had read one of our forum members had a Cab1L and Base1L....thought maybe they would know the answer, but maybe they don't have a cab2.

Was the OP question ever resolved?

The CAB2 will NOT talk to a BASE1-L.

That is interesting, since the CAB-1L will talk to the Legacy base.

The difference is that the CAB2 expects capabilities that the BASE1-L doesn't have.

That is correct. The information that populates the CAB2 screen exists only in the LEGACY Base. It is NOT possible to use a CAB2 remote with a BASE-1L. You may, however, use a any combination CAB2 and CAB-1L hand held remotes in conjunction with a single LEGACY base.
