address you will use to control the consist is not necessarily the address of the
lead or head end loco, we use the term “TOP” for this special address. The
TOP address can also be the train number.
You will not be able change the speed or direction of any individual loco that
is part of an MU, however you can control individual locomotive functions.
Locomotive speed and direction for all locos in the MU are controlled by the
TOP address
4.9 Adding a Locomotive to an MU
To MU two locomotive addresses together with the DT602:
1. Choose two locos you want to MU together. Place them on the track. Make
sure that both locos that will be part of the MU are running in the same
physical direction. Select and run the first loco to determine which way it
is headed. Then select the other loco and run it in the
same physical direc-
tion
. They are now ready to consist.
2. Select the address you want to use to control the MU. This will be the TOP
address. To do this, press
enter the address numbers & press
again.
3. Press
again to re-enter loco selection mode, and the large numbers in
the Loco Info Area will begin to blink black and gray. The soft keys will
also change to give you the options “MU” “Recall” and “MORE”.
4. Press
key labeled “Mu”: This will enter MU mode. The display will
now show the TOP address below the blinking loco address number. It will
say “Consist To:” and then your chosen TOP loco’s address. It will also
now show a “MU+” soft key.
5. Use the Keypad to enter the locomotive address you wish to add to the
consist.
6. Press
key now labeled “Mu+” to make a consist addition of the newly
selected address.
7.
The DT602 will consist the flashing address to the TOP loco, exit MU
mode and the TOP locomotive will remain selected on the throttle
8. To add additional locos to the MU/consist repeat steps 3-6.
If your MU could not be set up the DT602 will display and informational mes-
sage in the Scrolling Help Text line.
This happens when you try to link to an address that is already part of an MU
or link an address that is under the control of another throttle. For example if
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.
