ZIMO Decoder - Software Update .......................................................................... 17
NOTE:
ZIMO decoders contain an EEPROM which stores software that determines its characteristics and functions. The software version can be read out form CV #7 and
#65. 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 "Software Update"! Software
updates are available at no charge if performed by the end user (except for the purchase of a programming module); Updates and/or upgrades performed by ZIMO
are not considered a warranty repair and are at the expense of the customer. The warranty covers hardware damage exclusively, provided such damage is not
caused by the user or other equipment connected to the decoder. For update versions, see www.zimo.at.

RailCom will be further developed over the coming years and add new applications, which of course require new software updates in decoders and other equipment. All ZIMO decoders as of 2009 are able to send their own loco address from an insulated track sections (with a so called broadcast method, very fast, although only for one loco in that section), send CV content on demand along with some decoder data such as actual speed in km/h, load and decoder temperature.
