A- Key
starts the working area
Address Programming
;
Here, either press the A-Key again,
to
read
the current decoder address, or enter
a new address
and press the F-Key or W-Key
to
write
(program) the new address
into the decoder; see below.
U- Key
starts the working area
CV-Programming
; where CVs can be programmed or read-out;
details see further down in this chapter!
E- Key
exits
Service Mode Programming (switches back to
LOCO
with the previous address;
in contrast to the
F-Key
where the identified address will be activated).
SERV PROG
– Decoder address programming
(after
A-
Key
)
If the step “…identify decoder” (with
TP-Key
) was performed before calling for “…program new ad-
dress
” (with
A-Key
), the current address and the other data are already known by the controller and
displayed next to the address input field (until now
: …)
Type a new address
in the entry field
and press the
F- Key
programs
the decoder to the new address as
a vehicle
decoder
W- Key
programs
the decoder to the new address as
an accessory
decoder
In the case shown here (where the decoder was first "Identified" with the
TP key
) only one of
these options (
F
or
W-key
) appears because the type of decoder (vehicle or accessory decoder)
on the programming track is already known, due to a successful "identifying" or "address read-
out" procedure.
As for the other case, see further down in the text: "Program decoder WITHOUT "Identification".
After programming an address (or attempted programming) with the
F
or
W-Key
, one of the
following confirmation messages appears:
ACK
for a successful (= confirmed) programming step, or
NACK
in cases where no confirmation was returned by the decoder. The
associated alert
”ATTENTION: Address-
ing not confirmed”
means: the decoder did not send acknowledgement pulses, but the address MAY have
been programmed successfully anyway, BUT: it IS ALSO POSSIBLE that the address was programmed cor-
rectly but the previous CV #29 values were changed to ZIMO default values; this could affect the speed step
mode (ZIMO default: 128), analog control (ZIMO default: yes) and RailCom (ZIMO default: yes).
ERR
the decoder has rejected the (address) programming step
The MX32 screen also
displays which CV’s have been set to what values with the previous address
procedure, each with
ACK
/
NACK
Programming decoders WITHOUT preceding “Identification”
(
A- Key
w/o preceding
TP- Key
)
In this case, the usual list of data is not shown, instead
the warning:
“
ATTENTION: Unidentified Decoder
– Ad-
dress programming is not safe
“.
This means: it is NOT (yet) CERTAIN whether
1) a decoder or vehicle with decoder is even on the pro-
gramming track
2) the decoder is of the proper type (for a vehicle or
accessory) that can be programmed with the
F-Key
or
W-Key
3) it is a ZIMO or third-party decoder (important in relation
to CV #29 default values) or
4) it is even possible to communicate (read/write, with or
w/o acknowledgment) with the decoder on the pro-
gramming track.
However, the warning
“
ATTENTION: Unidentifi
ed Decoder”
does NOT mean that programming or
read-outs with acknowledgments are not possible, but only that there is an uncertainty in this regard.
The “deficiency” of a missed identification can either be rectified with the
A- Key
(which is the second A-Key actuation, and equivalent to A+A)
to
read out
the address,
(which is sufficient for a
“minimal identification” that allows for a secure address programming)
or
not rectified by immediately programming the new address unsecured,
at one’s own risk by typing in the
new address and confirming it with the
F
or
W-Key
..
If the decoder type is
not known
, it is up to the
user to press the CORRECT key (F or W).
The WRONG button ei-
ther prevents a successful address programming (namely when the decoder is able to acknowledge it, is read-out
within the addressing process and thereby recognizing the key as the wrong one) or a failed programming (if the de-
coder cannot acknowledge - e.g. because no load is connected).
F
A
(in
this
example
AFTER
identific-
ation
with TP)
NOTE: During the actual addressing procedure the
necessary data is always read out (especially CV
#29), even if previously "identified", because the
system can only recognize in this way whether the
decoder on the programming track has possibly
been replaced with another one.
The foregoing “identification” is therefore not really
necessary for programming an address but does
offer more information.
If only the “old” address is of interest, it can be
read out directly (by pressing the A-Key again, see
below); this is also faster than the decoder “identi-
fication”.
NOTE
Replacing the decoder or vehicle on the programming track with another one without exiting and
re-entering the
SERV PROG
mode is permitted and can be quite useful for saving time during
“mass”
address programming. In such a case, take the decoder (or vehicle) from the programming track after
a successful programming process (confirmed with
ACK
, see above), connect the next decoder to (or
place the next vehicle on) the programming track and continue with the A-Key, type in the new address
and press the F-key.
