HA7net - Ethernet 1-wire Host Adapter (panel)

Description

The HA7Net is a low-cost Ethernet to 1-Wire interface designed to simplify the process of integrating distributed 1-Wire / iButton networks into your application or system. The HA7Net allows end users to enjoy easy remote access to their 1-Wire sensors and devices. Likewise, integrators and OEMs can substantially decrease development time and installation costs associated with deploying systems based on Dallas Semiconductor 1-Wire technologies.

Communication Protocols

Primary communication with the HA7Net is accomplished via the HTTP protocol, with optional 128 bit SSL data encryption. The actual data is exchanged in the form of html documents which have been designed to accommodate both human readability and 100% reliable machine parsing. This is accomplished through the use of unique, predictably named form fields that can be automatically parsed by most DOM parsers, or easily digested via regular expressions on lighter weight platforms. Data is passed to the HA7Net in the form of parameters placed in the URL. Since the result pages are human readable, both proof of concept and integration times are reduced as you can effectively interact with 1-Wire devices via the HA7Net using a standard web browser.
