LCS SER2 and TIU upgrade...seems to have eliminated the serial signal...or changed it????

Ed,

Is it possible the TIU upgrade version 6.1 screwed up the serial port/output somehow? 

Almost certainly that is not the case at all.

Much more likely is that when you removed the TIU from the layout and then replaced it after the upgrade, you put it back connected differently than it was previously.

Alternatively, something else was changed.

Thanks. If the upgrade is not the issue I’ll keep looking. 

I now have them working in command mode.  Prior to the update, I assigned Accessory, vice Engine ID#s.  They worked fine. After the TIU and Remote upgrade, they would not respond to Accessory IDs.  However, I discovered if I used the old ID# as an Engine ID#, they both worked fine.  Wifi is OK also for the Gantry but Log Loader, not so much.  I'll try to figure out why this ID switch, but now that they are working and the Engine IDs don't conflict with anything in my roster, I'm calling this case closed.  The only curious thing to me is the Gantry manual talks about icons on the CAB2 for the magnet/hook...walkie talkie, etc. My CAB2 is in Cab1 mode and shows no icons, only numbers.  ???

Ed, unplug the MTH cable from the SER2.  If the Lionel TMCC accessories operate normally from the CAB2 without the TIU connected, then the problem lies with the MTH gear.

To further diagnose what is going on, download the LCS WiFi Monitor LE, install it on a notebook, and connect to the Lionel WiFi.  You can see all of the commands transmitted on the PDI buss with the software.  After you are comfortable watching normal operation commands going to the TMCC accessories, plug the MTH cable into the SER2.  See what changes with the TIU connected.  You might want to record a test sequence with the CAB2 so you can replay the same commands with and without the TIU connected.

Tracker John, that’s an excellent idea. I will do that today. I didn’t know of this software but after your suggestion I watched a tutorial by Lionel on YouTube. We’re supposed to get snow over the weekend so this is a very good reason to stay in doors and work this project!   Thanks.

For some reason when I try to install the program on my desktop running Windows 8.1 I get a visual basic error: incompatibility that I can't fix.  My laptop is running XP and likewise it will not install on it either as some system files are out of date and apparently can't be updated, probably because XP is no longer supported.  Now I have a good reason to replace my laptop! 

The software was written in the XP era but your system apparently doesn't have the underlying VB support libraries (or correct versions) loaded.  It installs and runs on my Windows 10 devices.  Some AV programs don't like the old libraries that come with it.

I replaced my 14 year old computer with a new HP.  It runs Windows 10. Hopefully it will run MonitorLE. 

John, new computer runs MonitorLE. Slick utility. Thanks.
