1-WIRE BUS MASTERS 

Also known as host adapters, 1-Wire Bus Masters are available in a wide variety of form factors and interface types. They are divided into two basic categories: Intelligent Bus Masters - Our Intelligent Adapters relieve the host from the burden of generating the time-critical 1-Wire communication waveforms while supporting all Dallas 1-Wire and iButton devices with simple ASCII commands that can be easily generated. This enables 1-Wire networks to be used by nearly any device that can read/write ASCII data via any of the following interfaces: RS232 / RS485 / TTL. 1-Wire Level Converters - Our 1-Wire Level Converters require the host to generate the 1-Wire timing, and are compatible with both the Dallas TMEX API's, and our own OneSix DDE / OPC server software for Microsoft Windows. Below is an overview of the 1-Wire interface products offered by Embedded Data Systems. For detailed information, clicking on either the images or the links below. If you need additional help selecting the correct 1-Wire Bus Master for your application, please feel free contact us.
