Configuring the MX695 - MX699
ZIMO decoders can be programmed in
-
“Service Mode”
(on the programming track ) for assigning a new address or reading and
writing CV content, or in
-
“Operations Mode” (a.k.a. “Programming on the main” or “PoM”), which is done on the
main track;
programming CV’s “on the main” is always possible in operations mode. However,
an acknowledgement of successful programming steps or when
reading out CV’s is only pos-
sible with a DCC system capable of
“RailCom”.
5.1
“
Service mode
” programming
(on the programming track)
Before programming is possible, it must be unlocked with
CV #144 = 0
or
= 128
(the latter allows programming but prevents decoder updating).
This (CV #144 = 0) is normally the default setting, but the programming lock is activated in many
sound projects to prevent accidental changes. It is therefore recommended to check that CV, es-
pecially when attempted programming has already failed.
Successful programming steps as well as CV read-outs on the programming track are acknowl-
edged by decoder-generated power pulses, by briefly turning on the motor and/or headlights. If
the motor and
/or headlights do not draw power (i.e. they are not connected) or don’t draw
enough power, acknowledgments for successful programming or CV read-outs are not possible.
To make acknowledgments possible in such cases activate CV #112 bit 1, which enables the de-
coder to use an alternate acknowledgment by sending high frequency pulses from the motor end
stage. Whether this method is successful though depends on the DCC system used.

Note: The programming
lock has no effect on
CV #144, which is
therefore always ac-
cessible for unlocking.
Bits

= 0: Update and programming lock not active
Bit 6 = 1: No programming possible in
“service mode”:
protection against unintentional program-
ming.
Note: Programming in “Operations Mode“ is not
locked because any such programming only
applies to the active loco address and re
programming the wrong locomotive is there-
fore not possible.
Bit 7 = 1: Software updates via MXDECUP, MX31ZL
or other means are locked.

Attention: The CV values of a sound decoder in the delivery state do NOT correspond with
the default values in the following chapters, but rather the initial values of the loaded sound
project!
This applies most often to
CV #29
– analog operation is usually turned off (Bit 3 = 0); CV #29 = 14 turns this on if desired.
CV #144
– the update lock may be activated (Bit 7 = 1), sometimes even the programming
lock (Bit 6 = 1); before updating or programming a decoder, set this CV to CV #144 = 0.
CV #3, 4
– acceleration and deceleration CV’s are often set to higher values (i.e. 12).
CV #33 and following
– the functions are often mapped to a specific loco model.
…and of course the sound CV’s (from CV #265) and (less frequently) all other CV’s.
5.2
“Operations mode” programming (on-the-main)
Programming in
“Operations mode”, otherwise known as “Programming-on-the-main” = PoM
“Programming-on-the-fly”.
According to the current NMRA DCC standards it should only be possible to program and read
CV’s on the main track, but not assign new vehicle addresses. However, certain DCC systems
(among them ZIMO beginning with the system generation MX10/MX32) will allow addresses to
be modified on the main track with the help of bidirectional communication.
All ZIMO decoders are equipped with bidirectional communication (
“RailCom”
) and can there-
fore (with a corresponding DCC system such as ZIMO MX31ZL and all devices of the new
MX10/MX32 generation) read, program and acknowledge successful CV programming steps in
operations mode (on the main track). This requires RailCom to be activated, which is the case
if the following CV’s are set as:
CV #29, Bit 3 = 1
AND
CV #28 = 3
This is usually the default setting, but in certain sound projects or OEM CV sets it may be
turned off by default and must first be turned on again.
