Telegesis ZigBee Technology

EAP-S   Ethernet Access Point
New EAP-S     Initial quantity now sold. Available end June.

Download - Telegesis EAP-S product brief

The EAP-S is also available in a Power Amplified form – see STRX2-PA for range & specification details

The Ethernet Access Point is a “gateway” which allows access to STRX2 mesh networking modules over an industry standard Ethernet IP Network. In addition, once the IP address of the EAP has been established and Firewalls permitting, the EAP can be accessed from anywhere in the world.

For example, multiple EAPs can be deployed, each connected via Ethernet to a ZigBee PAN in different parts of the building.

For faster production development the device carries the Telegesis AT Style Command line interface which allows the quick integration of meshing radio technology without complex programming or RF design experience.

EAP Features

• Combines a Telegesis STRX2 module with a Incorporates a Lantronix serial to Ethernet bridge
• Complete TCP/IP protocol stack and Windows deployment software
• Interface: Ethernet 10Base-T or 100Base-TX (Auto-Sensing)
• Protocols: TCP/IP, UDP/IP, ARP, ICMP, TFTP, Telnet, Auto IP, DHCP
• Link and activity indicator (LED)
• Management: Telnet and Microsoft Windows®-based utility for configuration
• Can offer access to the remote AT-Command Inteface via a serial Com port.
• SIF interface for Custom application development and real time debugging of custom firmware.
• External power supply required 

Uses

• Remote diagnostics and upgrades.
• Networked remote monitoring and control.
• Remote data acquisition - e.g. temperature monitoring.
• Bridging between ZigBee and Ethernet.

Windows software
As a helpful starting point for developers, Telegesis supplies the simple Telegesis Terminal Application with the EAP. Device deployment and network initiation are simplified with Dynamic Host Protocol Support (DHCP) and additional IP configuration methods via the included Windows®-based Lantronix DeviceInstaller software.

The supported Com Port Redirector (CPR) software maps ‘virtual COM’ ports on a PC platform and redirects application data destined to an attached device. Rather than going out of the local COM port, the data is transmitted across the Ethernet network to/from the Lantronics XPort Direct using TCP/IP. CPR is also licensed as an API to OEMs for incorporation into their applications on non-PC platforms such as a web pad or PDA.

Power Supply

When ordering please note that an external power supply is available at additional cost.

OEM format

The EAP is also available as an OEM product;

• Without the Telegesis AT command set - use ST's Development Kit to develop your own firmware application.
• With or without plastic cases.
• Your own logos and artwork printed straight onto the plastic.
  

Telegesis ZigBee Technology - Router-S
New Router will be available later in June

Acts as a “router” which enables increased distance between nodes in a ZigBee network.
For example, if the distance between two nodes is too great for communication to be established, place one or more Routers in-between and the mesh will self-form. A Router has the same distance parameters as a Telegesis module.

Router can be placed where needed in a mesh

Router Features

• Incorporates a Telegesis ZigBee module
• External power supply required 

Uses

• Extend distance between nodes in a ZigBee network
