Specifications

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.
