Introduction

WLg-DONGLE gives access to any serial equipment from Windows, UNIX & Linux computers connected to your WiFi Ethernet TCP/IP network, make it possible to communicate between two distant serial equipments through the network, or directly with a peer to peer connection (Ad-Hoc mode).

 

The support of the Telnet (RFC 2217) extension associated to a COM ports re-director enables distant serial equipments connected to the WLg-DONGLE to be directly used by Windows & Linux existing applications using standard COM ports.

The WLg-DONGLE device is also designed to work as a wireless bridge between MODBUS ASCII/RTU protocols and the radio network, this feature allows connecting any serial MODBUS equipment to the radio.

 

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