Just got word that the new version of LSU is available now from Lionel.
The new features of this release are:
Connects to LCS WiFi module in addition to supporting a wired serial connection to Legacy 990 command base
Adds support for Trains, Switches, Accessories and Routes.
You can get it directly from here or use the software update link here on the Black Module Product Page! The manual is here.
This version will allow you to do much more! Name and edit accessories, switches, and routes. You will also as before be able to save your data base, make system modules (requires the black module and system download from Lionel's website), and multi-engine modules (requires a black module). You can edit ENG names, road numbers and the settings associated with them. Edit the numerical option panels (lower left and right) to bring lighting features (engine must be equipped) onto the main numerical keypad screen. There is probably something I am forgetting but that covers the big stuff!
The LCS SER2 cannot be used by the Legacy System Utility. To use LSU, your computer must either be directly connected to your Legacy Command Base using the Legacy Y Cable, or connected wireless via a Layout Control System LCS WiFi module.
