Legacy CAB2 Problems

Describe the symptoms of "locked in cab1 mode".

How are you trying to change it?

INFO, Scroll, Scroll, and select the desired operating mode.

If that doesn't work, there is a reset button recessed on the back.  Try pressing that for a few seconds.

Gunrunnerjohn, When I have a legacy engine on the track, the screen on the CAB2 always shows CAB1. When I use my CAB1, I see that whatever engine number I punch in on the CAB1 shows up on the CAB2 screen. I will try your remedy and see what happens. I did put both blue 1.4 version modules in their respective places ie: CAB2 base and CAB2 remote but that didn't change anything.

Hi Paul,  This sounds very strange. How have you got your TMCC (CAB1) and Legacy (CAB2) systems wired?

Nicole, the CAB2 base is connected to the CAB1 base via the 3 connector cord from Lionel with the 3rd connection not connected to anything. CAB2 base also has the one wire going to the track and of course its power cord is plugged in.

I tried the info scroll scroll to no avail. I pushed in the little reset button on the back of the CAB2 also to no avail. When, on the CAB2, I press eng, then the number, a CAB1 message shows up on the screen. Is there a way to erase everything on my CAB2 remote and base and start clean? There is some extra wiring and track work I need to do before I can get back at this problem. So give me a few days and I will get back to all of you. Thanks again, MilwRdPaul

You can do a complete reset that will erase all information from the base. The instructions are in the manual.

Out of curiosity, where do you find the reset procedure?

It sounds like he does not have the cab 2 engine programmed into the cab 2 handheld. 

You have the modules in place, did you actually do the programming procedure to install the firmware into the respective units?

Hi, as WB47 has asked, have you actually loaded the engine details (Manually for TMCC locomotives, and using the modules for Legacy locomotives.) into your Legacy system? 

Hi everyone, I was just downstairs at the layout. I loaded the blue cab module into the CAB2 remote. When finished, I loaded the blue base module into the CAB2 base. When finished I loaded the orange module for the F7 into the CAB2 remote. When finished, I hit the eng button, CAB1 remote came up on the screen. Where in the version 1.4 manual is the info to erase everything and start over? My wiring is fine. Does anyone else use TMCC and Legacy together? This really has me baffled because up to 3 or 4 days ago, everything was working fine.

press the info button page 10 of the manual. read the screen and then start scrolling.

Hoo-Rah! I don't know what I did, but I guess I pressed enough buttons on the CAB2 to get my Legacy engines to run in the CAB2 format. Thanks everyone for your imput. Just to be safe, I unwired my TMCC system from the layout and will wait until the CAB1L becomes available. I love Command Control in both Legacy and DCS, but it would be nice it there weren't any problems with it!

You are right of course, I just got sick of the extra wiring. I'll probably put it back together because I like having that extra remote.

Don't connect the TMCC base to the track common.

Actually, I lied as well, it really is a two-way conversation.   The TMCC base actually talks to the Legacy base when you use the CAB1, then the Legacy base forwards the commands to the track signal.  I removed the incorrect statement.

No problem. I think that I read in my Legacy manual that if I used the CAB1 and CAB2 both addressing the same engine, it causes problems. I think that is what I might have done which caused the CAB1 mode on my CAB2. Boy, this gets confusing! I should open a taxi business with all these cabs.

Well, yes!  I have never even tried that, knowing that would doubtless confuse things!  You can get an engine pretty confused just addressing it with multiple remotes.

I can get pretty confused with multple remotes. Thanks for all your help, Paul

Use me a data point but I don't have any problems at all with my CAB-1 and CAB-2 operating on the same layout.  I run both Legacy and TMCC engines.  I don't see anything on the screen of the CAB-2 when addressing engines.  Nothing gets "confused" either.  The bases had to be wired a certain way to make sure this worked though.  

We were talking about addressing one engine at the same time with both the CAB1 and CAB2 fighting it out for control.

There is no indication, or even any knowledge by the CAB2, of someone operating the engine with the CAB1.  The communication goes from the CAB1 to the TMCC Base, on to the Legacy Base, and out the track signal to the locomotive.
