CV 19
Consist Address

Description

Contains address and direction data for consist operation:

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. 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 0 or 128 disables consist addressing. Setting

CV to a value between 1 and 127 enables consist addresses 1 to 127

with the locomotive oriented facing forward in the consist. Setting CV to a

value between 129 and 255 enables consist addresses 1 to 127 with the

locomotive oriented facing backwards in the consist.

Default Value:
