G tting Start d
The Bachmann E-Z COMMAND®locomotive decoders
can be used with standard digital control systems
with an NMRA conformance seal. If in doubt, ask the
system suppliers.
Note the maximum current-carrying capacity of the
outputs must not be exceeded. Exceeding this will
destroy the decoder. The metal components of the
decoder must not touch the metal parts of the chassis
or the body of the locomotive. This could cause a
short-circuit within the locomotive decoder which
might destroy it.
Extreme care must be taken when operating locomotives
equipped with E-Z COMMAND®decoders using
overhead line (catenary), either on conventional DC or
DCC layouts. Choose either catenary or track power
operation (not both), or the locomotive could be subject
to double voltage that would destroy the decoder.
Before installing an E-Z COMMAND®Decoder, check the
loco in normal DC operation to make sure that it works
as it should before modifying the locomotive. Replace
worn wheel contacts, motor brushes and bulbs as
needed. nly a locomotive that is mechanically fine will
function properly with a locomotive decoder.
Installation
Some decoders come with a NMRA/NEM652 medium
plug. To install this type decoder simply remove the
dummy socket in your locomotive and install the
decoder plug. To ensure the headlights work correctly,
you must align the plug properly. Pin 1 of the plug
connects to the orange wire (Fig 1). Ensure this is
aligned to Pin 1 of the locomotive. If the plug is installed
backwards the lights will not work. When installing or
removing the plug, be careful that the pins do not
become bent or broken. Not : Pin 1 is indicated by
either “A1” or a colored dot marking.
To install a decoder with wire harness, refer to the wiring
guide below for proper connections.

Follow the E-Z COMMAND®instructions to change the
decoder address. The decoder will operate as supplied
but also has advanced programmable functions
accessible using suitable equipment. Do not worry if you
do not understand all of the functions of the decoder.

Programming th d cod r
PLEASE NOTE that except for allocating address and
direction, the standard E-Z COMMAND®system is unable to
program decoder CVs. A more advanced system, such as
Bachmann’s DyNAMis®WirElEss DigitAl COMMAND
CONtrOl is required to program decoder CVs.
The locomotive address, acceleration and deceleration
delay, and all other features of the locomotive decoder can
be changed as often as desired by reprogramming. The
features are "stored" permanently in special locations even
when the operational voltage is switched off. These
locations are called "configuration variables" or simply CV.
The configuration of the variables is done electronically,
which means that it is not necessary to open the locomotive
again after the decoder has been installed.
n delivery, the decoder is programmed for operating with
the basic address 03, 28 speed steps and an internal
speedline. The decoder can be used immediately on
purchase with these basic configurations. All configurations
can, of course, be changed.
T sting th installation on quipm nt oth r
than Bachmann E-Z COMMAND®.
Place the locomotive on the programming track (without its
housing) and read the address. At the factory, the decoder is
programmed to the address 03. If you have connected the
decoder correctly thus far, you should now be able to read
the address. If you are not able to do so, it is possible that
you made a mistake when connecting the wires. Do not
subject the loco to full-running track power until you obtain the
correct "03" address read-out. Check the wire connections and
change them as required. You should now be able to
send your locomotive on its first test run on your layout.
