Operating parameters for the decoder
The decoder has numerous setting possibilities (e.g. its address) which determine its actions or
enable conclusions to be drawn concerning its actions. These settings are or will be stored in
so-called CVs (CV = Configuration Variable, please refer to the table at the end of these instruc-
tions). There are CVs which only store a single piece of information (referred to as a “byte”), and
others which include 8 information units (bits). The bits are numbered in sequence from 0 to 7.
You require this knowledge for the programming. The programming of the CVs can be very easily
carried out with a DCC control device which is able to program “CV-direct” in bytes and bits. The
programming of some of the CVs is also possible via the register programming. All of the CVs can
also be programmed on the main track in bytes as long as your control device is able to carry out
this programming form (POM -Program on Main). (You will find more information on this subject
in the operating instructions for the digital control device concerned).
Operational test
Please ensure that the driving stages set in your central unit/digital driving controller are the same
as those in the decoder (CV29).
Flashing lights indicate an incorrect driving stage setting.
For example, if the decoder has been set to 14 driving stage operation but the control (multiMOUSE,
etc.) has been set to 28 driving stages. In this case, the CV29 should be programmed with the value
“6“ (= analogue detection + FS 28) .
multiMAUS: Menu “PROGRAMMING (2)“, CHANGE CV (2.1.) call up “CV29“, enter the value “6“
and activate with the “Light / OK“ key.
Locmouse 2/R3: Press “P“ + “Stop“ at the same time, confirm message “06“ with “P“.
If the locomotive lights do not operate, the decoder was inserted incorrectly into the interface.
Reinsert decoder turned by 180° in the interface.
Locomotive address
The decoder is set to the Address 03 by the manufacturer. For information on programming a dierent
address, please refer to the corresponding chapter in the multiMOUSE/locomotive mouse manuals
or the instructions for your digital system!
Only locomotive addresses between 1 and 99 can be stored in CV1. The programming of locomotive
addresses over 100 (“long addresses“) is possible with the ROCO multiMOUSE (Art. No. 10810)*. It
is also necessary to activate Bit 5 (= 32) in the CV29 before programming long addresses.
multiMAUS: In menu “PROGRAMMING (2)“, “LONG ADDRESS“ (2), enter the address
and confirm with the “Light/OK“ key.
Operation on analog layouts
You can also use a locomotive which is equipped with this decoder, with a conventional system:
a change in the direction of travel is only possible after the controller of the control device has
been set to zero. Only then is it possible to select the new direction of travel. The lamp brightness
depends on the speed of the locomotive. The lamps cannot be switched o and special functions
cannot be additionally activated. A reprogramming of preset addresses and features is not possible
in analogue operation.
