CV 19
CONSIST ADDRESS
Description
Contains address and direction data for consist operation:
bit 7 bit 0
CDIR A6 A5 A4 A3 A2 A1 A0
Bit 0-6: A0-A6, Consist Address Value
Bit 7: CDIR, Consist Direction
0 = Normal Direction
1 = Reverse Direction
The CDIR bit defines orientation of the locomotive within a consist and specifies whether the direction bit
in a speed/direction data packet should be inverted.
Bits A0-A6 assigns the consist address from 0 to 127 (0-0x7F).
If A0-A6 = 00, consist commands are ignored. Otherwise, if the decoder receives a valid command
packet whose address matches the consist address, the packet will be processed as any other packet
with the following exceptions:
Long Form CV Access instructions will be ignored.
The direction bit in a speed/direction or advanced operation packet is inverted if CDIR = 1.
Only the auxiliary functions enabled in CV 21 and CV 22 are allowed to change.
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 continue to be
processed as normal.
In summary, setting CV 19 to 00 or 128 (0x80) disables consist addressing. Setting CV to a value be-
tween 1 and 127 (0x01-0x7F) enables consist addresses 1 to 127 (0x01-0x7F) with the locomotive
oriented facing
forward in the consist. Setting CV to a value between 129 and 255 (0x81-0xFF) enables
consist addresses 1 to 127 with the locomotive oriented facing backwards in the consist.
Default Value: 00
