Ewon Flexy 202


The Ewon Flexy family is a range of industrial modular gateways that allows universal communication with varied field equipment regardless of the protocol used. It is possible to configure data acquisition & data logging, routing and more. The Ewon Flexy 202 is an Ewon gateway based on a serial port.
For the latest software updates and downloads, please visit the manufacturer’s website.

Routing capability between LAN and WAN Ethernet interface and Ethernet to serial gateway.

Internal database for data logging (real-time logging and historical logging up to 1,000,000 timestamps). Historical data can be exported to DataMailbox or transferred by FTP or email.

SD card reader

A/ for easy commissioning (firmware upgrade, backup, Talk2M registration) B/for Extended User Memory.


IP filtering, IP forwarding, NAT, Port forwarding, Proxy, Routing table, DHCP client/server, NAT 1 :1. (Applicable only to the serie 200)

VPN Tunnelling

Open VPN either through UDP 1194 or TCP 443 ( HTTPs port).

VPN Security VPN sessions are end-to-end encrypted using SSL/TLS protocol. Communications between the remote user and the eWON are fully encrypted using the SSL/TLS protocol, thereby ensuring data authenticity, integrity &
confidentiality. Indeed, all users and eWON units are authenticated using x509 SSL certificates and end-to-end traffic is encrypted using strong symmetric & asymmetric algorithms that are part of the SSL/TLS protocol
cipher suite.

Script interpreter for Basic language, Java 2 Standard Edition environment.


Embedded real-time clock, manual setup via http or automatic via NTP.

File Management FTP client and server for configuration, firmware update and data transfer.

Embedded web interface with setup wizards for configuration and maintenance (no extra software needed). Authentication with login/password and user management capability. Possibility of uploading custom web GUI.
