A hard copy of this instruction manual is not part of a decoder shipment; a few copies are sent to
the ZIMO dealer at no charge (about 1 for every 10 decoders shipped); more can be ordered for a
nominal fee or downloaded free of charge from
NOTE:
ZIMO decoders contain an EPROM which stores software that determines its characteristics and functions. The software version can
be read out form CV #7.
The current version may not yet be capable of all the functions mentioned in this manual. As with other computer programs, it is also
not possible for the manufacturer to thoroughly test this software with all the numerous possible applications.
Installing new software versions later can add new functions or correct recognized errors. SW updates can be done by the end user
for all ZIMO decoders since production date October 2004, see chapter 12!
Software updates are available at no charge if performed by the end user (except for the purchase of a programming module); Up-
dates and/or upgrades performed by ZIMO are not considered a warranty repair and are at the expense of the customer. The war-
ranty covers hardware damage exclusively, provided such damage is not caused by the user or other equipment connected to the
decoder. For update service, see

The full adjustable range of a Zimo command station (up to 24V) should only be utilized in special cases. Although ZIMO decoders are suitable for 24V operation, that may not be the case when interacting with some other equipment.
