upgrading an older LM-2
« on: November 06, 2026, 08:15:30 AM »
I received a few older decoder modules and I was able to update an LM-2S without any trouble so I moved on to the next one which is a non-sound unit.  I just connected the unit up to power and then found it with the controller and pushed the software to it.  With this next decoder my controller can't find it. 

I haven't tried to swap in a different 9-pin connector.

thoughts?

If you haven't already detected it and accidentality forgotten that you did (it happens) the LM could be dead or may have a password on it. If you don't know what that password could be then you can try resetting the password. The instructions for resetting the password are in the HC-3 instructions, page 26 to be exact.

Finally had a chance to get back to it and I figured it out... 

once the PW is reset you need to go to the find product option since the decoder doesn't show up in the list of locomotives. 

then you can change the name and enter a new password if you want. 

thanks!
