Setting Up CV21 for a Consist

CV21 allows you to set which F Functions you want the consist address to control. For

example, you will likely want all of your MTH consist engines to respond to Start-

Up/Shut Down (F3). Also, you'll likely want at your Front engine to respond to the Bell

and Horn commands (F1 and F2, respectively) and the Front Coupler (F7 on most

MTH models). Likewise, you'll want your Rear engine to respond to the Rear Coupler

command (F8 on most MTH models).

Please refer to the table below to see which bits have what decimal value and which F

Function they correspond to.

To do this:

1. Call up the Front engine on your DCC system

2. To set the Front engine to respond to the Bell (F1), Horn (F2), Start-Up/Shut Down

(F3) and Front Coupler (F7) you will want to write a value of 71 to CV21. This is

setting bits 0, 1, 2, and 6 ON.

a. CV21's bits are shown in the table below – the decimal value is shown in

parenthesis:

Function

F8 F6 F5 F4 F3

F2 F1

Bit

(Decimal

Value)

7 (128)

5 (32) 4 (16) 3 (8) 2 (4) 1 (2) 0 (1)

6 (64)

NOTE - CV21 is ONLY used when you have some value other than 0 written to

CV19. If CV19 = 0 then the values of CV21, CV22, CV23, and CV24 are not used

1. Call up your Middle engine (address 2 in the example)

2. Since you want to have the Middle engine respond to F3 only then write a value of 4

(CV21, bit 2 = ON)

3. Call up your Rear engine (address 3 in the example)

4. Since you want to have the Rear engine respond to the Start-Up/Shut Down (F3)

and Rear Coupler (F8) functions you want to write a value of 132 to CV21

Your engines are now set up according to the example above.

You will note that there is no F0 in CV21. This is because that function (FL) is

controlled by CV22. Please refer to the Advanced Consisting section for more

information regarding CV22.
