you MUed address 14 to the TOP loco 23 and then tried to MU another address 

to 14 you would get this error. If you wanted to add another loco to the MU 

with 23 as the TOP address, the right way to do it is to add that loco to 23, not 

to another address in the MU.

4.10  Removing a Locomotive from an MU

To remove a locomotive address from an MU:

1. 

Select the locomotive address you want to remove from a consist. To do 

this, press 

 and enter the address numbers. The large address numbers 

in the Loco Info Area will begin to blink black and gray, and the consist 

flag “cn” should show in the Loco Info area indicating this address is in a 

consist.

 

 

Press the   key to bring up the 5 additional loco selection tasks The 

numeric keys will now show soft keys; Recall, Status Edit, MU+, MU- and 

Dispch choices. 

MU- choice will only show if the address is consisted

.

2.  Press the 

 key labeled “MU-”: This removes the flashing address from 

the consist. The UT6 will exit MU mode and the removed locomotive will 

now be selected on the throttle.

4.11  MU of mismatched locomotives

If all the locomotives in the MU have performance characteristics that are 

closely matched, you can run all the MU’ed locomotives in e.g. 128 step mode. 

If the units are completely mismatched (for example, if you are running two 

different brands of locos with noticeably different characteristics), then we 

recommend speed matching the locos by programming the decoder with either 

Simple 3 step or Advanced 28 step loadable speed tables (See the Decoder 

Manual on the Digitrax web site for more information on these features of 

DCC decoders).

4.12  Controlling functions on MU’ed locomotives

Even though an individual locomotive is added to an MU so you can’t control 

its individual speed and direction, you can still control its function outputs 

independently as follows:

1. 

Select the loco that is part of an MU which you wish to independently con-

trol functions. To do this, press 

 enter the address numbers & press 

 

again to complete selection of the consisted loco.

2.  Now use the numeric keypad to control the  consisted loco’s functions like 

you would any other loco. The changes will take effect immediately if the 

locomotives are moving, otherwise changes will take effect when you rese

-

lect the TOP address on the throttle.

3. 

When you are finished turning functions on or off  for the consisted loco, 

simply select the TOP address and resume running the MU.
