ZIMO – Special function mapping
Function mapping procedure with CV #61 = 98:
NOTES:
The special effects (US-lighting, uncoupler, soft-start etc) can also be assigned using above procedure. CV’s #125,
126 etc. always refer to actual outputs!
It is possible to store and re-activate several function output allocations with the help of the “CV-set” feature!
This procedure allows free allocation of function outputs to function keys (on the cab) that is not possi-
ble by setting fixed values in configuration variables.
For a better understanding, the function keys are listed here in the sequence they are defined:
To carry out this procedure requires a bit more time and attention from the user.
1. F0 forward
2. F0 reverse
* Preparation:
Set the loco direction to “forward”, all functions off; the loco must be on the main
track (not on the programming track); the whole procedure is performed with
operations mode programming.
3. F1 forward
4. F1 reverse
5. F2 forward
6. F2 reverse
* CV #61 = 98
Writing 98 to CV #61 (in operations mode) starts the actual allocation procedure.
7. F3 forward
The decoder is now in a special programming mode, which will not end until the whole programming
procedure is completed or the loco is lifted from the track for a few seconds.
8. F3 reverse
9. F4 forward
*
The decoder is now ready to accept the first function output allocation, starting with function output
F0
in forward direction.
10. F4 reverse
11. F5 forward
12. F5 reverse
The function outputs (as many as desired) to be assigned to F0 in forward direction, are now actu-
ated
with the corresponding function keys (i.e. FLf, FLr, F1…F12).
13. F6 forward
14. F6 reverse
15. F7 forward
Because only one function key (F0) is available for FLf and FLr (headlights), it is necessary to press
F0 repeatedly to select the desired configuration (which alternately actuates the front and rear head-
lights).
16. F7 reverse
17. F8 forward
18. F8 reverse
The assignment must be confirmed by pressing the
direction’s key.
19. F9 forward
20. F9 reverse
*
The decoder is now ready to accept the next output assignment for
F0 but now for “reverse“.
21. F10 forward
Continue as above!
22. F10 reverse
Again, once a selection is made press the
direction’s key
to apply.
23. F11 forward
24. F11 reverse
* Continue in the same fashion for all function keys
(28 function-direction-combinations)
!
25. F12 forward
*
After the last function key (F12 “reverse”) has been assigned, the function outputs FLf and FLr (both
headlights) are turned on to indicate the end of this programming procedure.
26. F12 reverse
Confirm again by actuating
the direction key.
*
After confirmation, the finished allocations are
automatically activated
and CV #61 is set to “99“
.
Deactivation:
CV # 61 = 0 ... 97 (any value except 98 and 99) deactivates the function assignment
and again activates the function mapping according to CV #33 to #46 or
CV #61, if a value between 1and 7 is entered. The assignment defined
during this procedure though remains stored in the decoder.
An easy to work with tool that replaces the “CV #61 = 98” procedure will become available later, as part of
the
“ZIMO Service Tool” ZST,
where the desired functions can be “mapped” into a table and the proce-
dure described above will be carried out automatically!
Reactivating already stored data:
CV # 61 = 99 Reactivates the defined output allocations.
