SB3 SB3a SB5 Smartbooster EPROM Firmware Versions

DO NOT update anything unless you are trying to solve a problem.

To find the version number:

From the regular loco screen - LOC, on the cab: Press prog / esc 4 times to get to "Set Cmd Station."

Press enter

The first thing you see is the command station version, which we need to know. Hopefully, you see 1.65B. That is the most recent version.

Press PPORG/ESC to go back to your normal screen
