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.
a. CV21's bits are shown in the table below – the decimal value is shown
in parenthesis:
NOTE - CV21 is ONLY used when you have some value other than 0 written to
CV19. If CV19 = 0 then the values of CV21, CV22, CV23, and CV24 are not used
