Bachmann E-Z Command Getting Started

Programming the decoder
PLEASE NOTE that except for allocating address and
direction, the standard E-Z C
OMMAND
®
system is unable to
program decoder CVs. A more advanced system, such as
Bachmann’s DyNAMis
®
WirElEss DigitAl COMMAND
C
ONtrOl 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
l
ocations 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.
On 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.
Testing the installation on equipment other
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.
