11. Call up the consist address (address 4 in this example)
12. Press the F0 button to ensure the FL is toggled on. Most systems have a light
bulb icon to indicate whether F0 is active or not. Ensure that it is ON
Note
: The convenient thing about setting up the consist as described above is that it
allows you flexibility in the orientation of an engine in a consist; particularly the head
and tail engines where the FL control is integral. For example, if you wanted to flip
the Rear engine around and make it face forward in the consist all you'd have to do is
go into the Rear engine's address (address 3 in the example) and clear bit 7 of CV19.
In other words, just write the consist's address to CV19. The FL control will
automatically understand what you've done so there is no need to go in and change
CV22.
Below is a table that outlines which bits correspond to what F Functions F0, F9-F12
are used in a consist:
Setting Up CV21 for a Consist
CV21 allows you to set which F Functions you want the consist address to control.
For example, you will likely want all of your MTH consist engines to respond to
Start-Up/Shut Down (F3). Also, you'll likely want at your Front engine to respond to
the Bell and Horn commands (F1 and F2, respectively) and the Front Coupler (F7 on
most MTH models). Likewise, you'll want your Rear engine to respond to the Rear
Coupler command (F8 on most MTH models).
Please refer to the table below to see which bits have what decimal value and which F
Function they correspond to.
To do this:
1. Call up the Front engine on your DCC system
2. To set the Front engine to respond to the Bell (F1), Horn (F2), Start-Up/Shut
Down (F3) and Front Coupler (F7) you will want to write a value of 71 to CV21.
This is setting bits 0, 1, 2, and 6 ON.
