Basic Programming
Step 4: Configuring for Consist Operation
The decoder supports advanced consist operations, which use three related
CVs:
CV 19, Consist Address
CV 21, Consist Function Control 1
CV 22, Consist Function Control 2
Consists Explained
In a traditional sense a consist is a group of locomotives that are set up to
respond to throttle command as a single unit. For the purpose of lighting
decoders however, setting up a consist can also be helpful. This can allow
you to light an entire fleet of passenger cars that you can have set to one
single consist address, for example the train’s ID. The consist CV (19) allows
the decoders to recognize a new address assigned to the consist without
changing its primary or extended address. Additionally, they allow each car
to operate under the same address, but limit certain function properties to
only some cars in the consist. For example, if you had a passenger train of
five cars you would want the interior lights to turn on in all five, but you may
want only the rear car to have its marker lights lit designating the end of the
train.
Consist Address
Each car in the consist is assigned the same consist address by
programming CV 19 with the consist address between 1 and 127.
To deactivate the consist address and restore normal operation, CV 19 must
be reprogrammed to 0.
Note that when the consist address is set, the decoder will continue to
respond to instructions sent to its primary or extended address except for
speed and direction data.
The decoder will not respond to operations mode programming commands
sent to its consist address. These commands must always be used with the
primary or extended address.
Consist Function Enable
CV 21 and 22 allow you to define how each car individually responds
to function commands sent to the consist address. When the consist is
enabled, CV 21 controls which of functions 1-8 are active and CV 22 controls
the F0 function for forward (F0(f)) and reverse (F0(r)), as well as functions
9-12.
CV 21 and 22 take effect only when the consist address is set. When function
commands are used with the decoder’s primary or extended address, all
functions will continue to work regardless of the settings of CV 21 and 22.
