OW-SERVER-WIFI

129.00 €

1-Wire to Ethernet Server

The OW-SERVER-WIFI is an inexpensive WiFi to 1-Wire interface that is designed to efficiently monitor and control 1-Wire devices. The OW-SERVER-WIFI will allow you to use industry standard WiFi products (switches, hubs, etc.) to build the backbone of your 1-Wire based sensor/control system. This provides several important benefits: First, 1-Wire networks can be easily distributed over great distances without having to deal with the challenges associated with the installation of physically large 1-Wire networks. By distributing the 1-Wire networks, the individual 1-Wire MicroLans can be kept to a smaller physical size, thereby improving responsiveness/reliability and decreasing installation costs. Second, since the OW-SERVER-WIFI communicates over standard WiFi, you can take advantage of existing corporate WLAN, the Internet, and in-house MIS expertise for building out and maintaining the backbone of your sensor network.

The OW-SERVER-WIFI has been designed in such a way to minimize the amount of network resources needed to monitor 1-Wire devices. It maintains the latest readings of its 1-Wire devices which are updated every 2 seconds. This enables the OW-SERVER-WIFI to deliver a current reading without waiting for a time intensive temperature conversion (or other conversion) to be performed. Also, the OW-SERVER-WIFI is designed to push data when a user defined alarm occurs via SNMP traps. This significantly reduces the necessary polling rate for many applications while still supplying assurance that any problem will be detected in a timely manner.

A number of Ethernet protocols are used by the OW-Server including HTTP and SNMP. The HTTP interface is a simple webpage which shows the current overview of each connected sensor. By default, this page uses AJAX techniques to automatically update itself, insuring the data being displayed is current. The SNMP interface is divided into 3 sections: edsEnterprise, owTrap and owDevices. The edsEnterprise section presents basic product information, such as name and version. The owTrap section is where you define the IP address the trap should be sent, the high alarm, low alarm, and the hysteresis. The owDevices section data similar to the Overview and Devices webpage.
