Adding A Locomotive To An Mu - Digitrax Zephyr Express DCS52 Manual

can add any locomotive to your MU, no matter what kind of DCC decoder
is in your loco. You can even add an analog loco to your MU. You can add a
locomotive to an MU in either orientation and in any physical location in the
train. When you send commands to the MU you use the address of the TOP
locomotive to control the entire MU and the command station handles the rest
of the commands to the other locomotives in the MU. As the 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.

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.

TOP address. To do this, press the Loco Key, enter the address & press the
Loco Key again.

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
