IMPORTANT NOTES to SOFTWARE and SOFTWARE UPDATES: 

Software that determines the characteristics and functions of this product is stored in a FLASH-
EPROM. 

Current software

 is available at no charge from 

www.zimo.at

 (UPDATES). 

The software can be in-

stalled with the help of the program “

ZST” (Zimo Service Tool) 

but also at the DOS level with the 

program LOADHEX. The ZST program is available for download from the above web site at no 
charge.  

Updates can also be performed by exchanging the EPROM with a new one from ZIMO for a mini-
mum charge of EUR 10.00 to EUR 15.00 (handling and burning of the chip). An additional EUR 
10.00 will be charged if the old EPROM is not sent back. More information at: 

www.zimo.at

 . 

Some functions may depend on the software level of other components. It is therefore recommended 
to use matching software in the different ZIMO components.  

ZIMO cannot guarantee that future functions (including the ones covered in this manual) will be im-
plemented as planned or in the time frame suggested.
