Primary CVs
CV 19
Consist Address
Description
CV 19 contains address and direction data for consist operation.
A0-A6: Consist Address Value
CDIR: Consist Direction
0 = Normal direction
1 = Reverse direction
Additional Information
A0-A6 (bits 0-6) assign the consist address from 1 to 127. If A0-A6 = 0,
consist commands will be ignored. Otherwise, when the decoder receives
a valid command packet with an address that matches the consist, that
packet will be processed just as any other packet would be, with the following
exceptions:
• Long form CV access instructions will be ignored.
• The direction within a speed/direction or advanced operation packet is
inverted if CDIR (bit 7) = 1.
• Only the auxiliary functions enabled in CVs 21 and 22 are allowed to
change.
CDIR (bit 7) defines the orientation of the model within a consist and
specifies whether the direction bit in a speed/direction data packet should be
inverted.
When the consist address is active, speed/direction and advanced operations
packets sent to the decoder’s primary address (or extended address, if
enabled) will be ignored. All other instruction packets sent to the decoder’s
primary (or extended) address, including CV access and function control, will
be processed as normal.
To summarize, setting CV 19 to 0 or 128 disables consist addressing. Setting
CV 19 to a value from 1 to 127 enables consist addresses 1-127 with the
model oriented forward in the consist. Setting CV 19 to a value from 129 to
255 enables consist addresses 1-127 with the model oriented backward in
the consist.
