The software revision determines the available range of valid addresses for additional throttles

  • V1.28C: The only valid additional throttle address is 3. Unofficially address 4 might be available
  • V1.65: Valid addresses for extra throttles are 3, 4 and 5
    • The NCE USB, Mini Panel or AIU also have access to addresses such as 8, 9 & 10. Following a System Reset, all extra addresses will be lost and the version 1.28C limitations will be applied
    • Support for three additional throttles
    • All throttles have up to 6 recalls available
    • Thumbwheel can be used for CV changes
    • Pro Cab Mode: Multiple Power Cabs can be used together
    • Additional USB Commands
  • V1.65B: Same as 1.65, with the elimination of the system reset issues

These issues are also present with the Smart Booster having an address range of 2-5 for V1.28 and 2 through 7 for V1.65B.
