2. Press the MU Key. The FUNCTION Indicator Dot will go off and the
MU Indicator Dot will begin to blink indicating that you are
MU’ing.
3. Press the - Key to remove the loco address from the MU. The DCS50
will return to regular operation mode ready to run address 23 which
you just removed from the MU.
17.3 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 128 step mode. If
the units are completely mismatched (for example if you are running two dif-
ferent brands of locos with noticeably different characteristics), then we recom-
mend speed matching the locos by programming either Simple 3 step or
Advanced 28 step loadable speed tables (See your Digitrax Decoder Manual
for more information on these features).
17.4 Controlling Functions On MU’ed Locomotives
Even though an individual locomotive is part of an MU and 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 for which you wish to indepen-
dently control functions. In this case we will select loco address 23
which we added to an MU with address 09 in the previous example.
Press LOCO, enter the MU’ed loco’s address, press LOCO. You’ll
see the loco address and the Function and MU Indicator Dots will be
lit letting you know that you can control functions on this loco that
is part of an MU.
2. Use the numeric keypad to control the functions.
3. When you are finished turning functions on or off for the consisted
loco, simply select the TOP locomotive address and resume running
the MU.
4. Remember, you will not be able change the speed or direction of any
individual loco that is part of an MU. Locomotive speed and direc-
tion for all locos in the MU are controlled by the TOP locomotive
address.
