WiFi RS232/RS422/RS485 serial device server for industrial automation


WLg-IDA/S gives access to any serial equipments 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). WLg-IDA/S is designed for industrial and transportation applications, it can be used for material handling, real-time information transmission, and inventory management.

The configuration of the device is achieved using the web browser installed on your computer; it also offers SNMP administration / configuration and an optional C-Key which allows quick and easy on-site replacement of the WLg-IDA/S unit, eliminating the need to reconfigure the replacement part or to use any other equipment.

WLg-IDA/S fulfils the most severe requirements in terms of operating environment: operating temperature from -25°C to +70°C, shock and vibration proof according to MIL-STD-810F standard, IP30 seal rating.
