Serial commands to: Request or Configure Track Manager

Serial command to request information about the modes of all tracks or alter the mode of a specific track.

<=> <= «trackletter» «mode»> <= «trackletter» DC|DC_INV «id»>

Commands

  • <=> = Request the current Track Manager configuration
  • <= «trackletter» «mode»> = set a specific track to a mode (not DC)
  • <= «trackletter» «mode» «id»> = set a specific track to a mode (DC)

Parameters

  • trackletter one of:

    • A through H representing one of the outputs of the/a motor shield.

  • mode required if track letter supplied. One of:

    • MAIN
    • MAIN_INV
    • MAIN_AUTO
      Deprecated alias of AUTO but only when preceded by a separate MAIN command.
    • PROG
    • DC
    • DC_INV = DC reversed polarity
    • DCX = DC reversed polarity (same as DC_INV)
      With special alias of DCX for DC_INV
    • NONE

  • id the cab (loco) ID. Required when specifying DC or DC_INV / DCX

Response

The following are not a direct response, but rather a broadcast that will be triggered as a result of any track manager changes.

(for each track/channel)
<= [«trackletter» «state»] [«cab»]>

  • trackletter: A-H
  • state: PROG, MAIN, MAIN_INV, MAIN A, DC, DCX, NONE
  • id: cab(loco) equivalent to a fake DCC Address for DC and DCX only

Notes

  • Whenever a track's mode is changed, track power is automatically turned off on that track.
  • Since only one channel can be PROG, changing a second channel to PROG, will force the other to NONE
  • The response to DC_INV is DCX
  • The response to DCC_MAIN is MAIN A
