The WLg-LINK module used in the ACCESS POINT mode makes it possible to create an industrial WiFi wireless network from any industrial equipment featuring an 10/100 Ethernet interface.
Used in the BRIDGE mode, the WLg-LINK enables to connect any industrial equipment featuring a 10/100 Ethernet interface to the WiFi wireless network.
WLg-LINK module can also be used as a WiFi network repeater (WDS) in order to extend radio coverage, device supports both INFRASTRUCTURE and AD-HOC modes.
The WLg-LINK device is also designed to work as a wireless bridge between the wired MODBUS/TCP or PROFINET protocols and the radio network, this feature allows to connect any MODBUS/TCP or PROFINET equipments to this network.
Thanks to its built-in WEB interface, the setup of the device is achieved using the web browser installed on your computer (Internet Explorer, Netscape, Mozilla ...).
WLg-LINK doesn't require any additional software to be installed on your computer (no peripheral driver needed).
Product rely on the IEEE 802.11 a/b/g/h standards (2.4 GHz & 5 GHz), it features a 10/100 auto-sensing Ethernet interface available on a RJ45 connector.
The radio link is made safe by using most modern methods of protection: WEP 64/128 bits, WPA-PSK, WPA2-PSK and authentification IEEE 802.1x (RADIUS server).
The nominal range (open space) of the module is 300 m for a transmit power of +20 dBm and -92 dBm in reception (a/g modes) and -95 dBm (IEEE 802.11b mode).
It is powered from a +5VDC power source for a 3.5W typical consumption.

Application examples
The WLg-LINK enables to connect two Ethernet networks or two Ethernet equipments in the AD-HOC mode (direct radio connection without infrastructure) or within a radio network controlled by an Access Point as well.
The WLg-LINK can also be configured to work as a WiFi access Point.
WLg-LINK also supports the MODBUS/TCP & PROFINET protocols, thus you can easily replace a network cable by the radio link to connect any industrial equipment which rely on these protocols.
