8 Dallas 1-Wire
8.1 Introduction
Another convenient feature of the VK204-25 is that it provides a Dallas 1-wire interface in order to
readily communicate with up to thirty two 1-wire devices on a single bus. 1-wire communication is begun
by discovering the address of the device that you wish to communicate with. To do this you must send the
“Search for a 1-Wire Device’ command. After you have established the address of the device that you wish
to communicate with, you may begin a transaction with the device
