Access Point, 4-port Ethernet Bridge, repeater (WDS) module for wireless WiFi IEEE 802.11a/b/g & super AG, shipped with two 2dBi 2.4 / 5 GHz antennas


Main Features of the WLg-4LAN:

  • IEEE 802.11 a/b/g/h & super AG standards, up to 108 Mbps data rate
  • Security: WEP, WPA-PSK, WPA2-PSK and IEEE 802.1x (RADIUS)
  • Easy to use web based configuration
  • 4-port Ethernet switch 10/100 Base TX RJ45 auto-sensing network interface
  • +9VDC to +48VDC power supply
  • Small sized enclosure (L: 91 x W: 122 x H: 24 mm)

When used in access point mode, WLg-4LAN is the root element of an industrial WiFi Ethernet network.
When used as bridge, it allows connecting up to 4 Ethernet 10/100 devices to this network.

WLg-4LAN device is also designed to work as a wireless bridge between the wired MODBUS/TCP protocol and the radio network. This feature allows connecting any MODBUS/TCP equipment to this network.

Integrators and manufacturers (point of sales, medical instrumentation, industrial automation, security systems, video surveillance, automotive, building automation ...) can now rely on this new technology to build safety wireless network applications while freeing themselves from wiring constraints.
