Zigbee to Ethernet Converter: Bridging Wireless and Wired Networks

This document explains the concept of a Zigbee to Ethernet converter, referencing the broader topic of Zigbee technology. We’ll touch on its functionalities, applications, and some of the manufacturers in this space.

What is a Zigbee to Ethernet Converter?

A Zigbee to Ethernet converter bridges the gap between Ethernet-enabled devices and Zigbee wireless networks. It allows devices with an Ethernet port to communicate and interact within a Zigbee network environment. Think of it as a translator, allowing wired Ethernet devices to “talk” to wireless Zigbee devices.

This converter operates based on both IEEE 802.15.4 (Zigbee) and Ethernet standards. It commonly supports both mesh and star network topologies. Security is often a key feature, with 128-bit AES encryption usually included. These converters typically require a DC power input and can support a significant number of nodes per network (often around 99). They’re also sometimes called a Zigbee router or Zigbee bridge, depending on the specific interface requirements.

The Ethernet interface generally supports 10/100Mbps connections using an RJ45 port. Some converters also include RS232/422/485 serial interface ports for even greater flexibility.

Example Implementations

One example is the NPort Z3150 from MOXA. This device acts as a Zigbee Coordinator. It can be connected to a system’s Ethernet port and interface with Zigbee routers or end devices. It typically supports a data rate of 250kbps within a 100-meter range, operating at a radio frequency of approximately 2.4 GHz.

Another popular option is the XBee® to IP gateway from Digi International Inc. This device provides connectivity between a Zigbee wireless network and an IP network.
