If you just want few thermometers you can use this http://www.lecad.fs.uni-lj.si/~leon/other/wlan/wrt54ow/ You must know that there are two types of serial ports. One is with TTL level voltage which use 0V and 5V or 0V and 3.3V. This is used in wireless routers and some single board computers. Another standard is used in PC's and have voltage levels -12V nad +12V (or -5V +5V) AFAIK DS9097 will work only with -+ voltages. If you have basic soldering skills You can build Your own master with MAX232 and DS2480B. MAX232 can be bought in almost every electronics shop and Maxim/Dallas sends DS2480B samples for free. MAX232 is for voltage level conversion because DS2480B accepts TTL levels. If you want to have a ready to use device I think and USB adapter would be the best choice. These are basically build form and USB serial converter and a serial to 1-wire master DS2480B and are good for long networks. In Poland there is a company which builds an adapter like this (maybe they will send it to Hungary) http://www.meraprojekt.com.pl/mp00202.html Or you can buy from Hobbybords the are in US but probably ship to Hungary https://www.hobby-boards.com/store/products.php?product=1%252dWire-USB-Adaptor This one is a direct USB-1-wire adapter. -- p4trykx ------------------------------------------------------------------------------ Better than sec?
