7. Set CV22 to a value of 2 to the Rear engine's address to tell the Rear engine that you
want to control its FL control with the F0 button at the consist address. The engine
will give you two horn blasts to announce that it received the CV change
8. Ensure F0 is deactivated at the Rear engine's address. Most systems have a light bulb
icon to indicate whether F0 is active or not. Ensure that it is OFF
9. Call up the Middle engine on your DCC handheld; address 2 in this example
10. Ensure F5 and F0 are toggled OFF. You may have to toggle F5 on/off a couple
times to get the lights in sync with the DCC command station. This will depend
upon your DCC system
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

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.
