TDS-5041-I-M12 is an innovative secure 4-port RS-422/485 to 1 port LAN secure device server. It features TCP/IP and versatile operation modes such as Virtual Com, Serial Tunnel, TCP Server, TCP Client, and UDP. In addition, the Windows utility, DS-Tool, can configure multiple devices and easily set up the mappings on Virtual Com.

Features including NAT Router Pass Through, DDNS, and PPPoE make it more convenient for administrators to configure O-Ring’s device servers through NAT router from different IP domains or securely via the Internet.

On the other hand, TDS-5041-I-M12 can simultaneously transfer data up to 5 redundant host PCs to avoid Ethernet connection breakdown or any host PC fails. Furthermore, the TDS-5041-I-M12 features HTTPS, SSH, and SSL encryption to assure the security of data transmission.

The TDS-5041-I-M12 supports 4 x RS-422/485 interfaces on 5-pin M12 A-coding connectors and provides one wide range power input, 12~48 VDC, on a 5-pin M12 connector. Alongside this a massive operating temperature of -40~70°C means the TDS-5041-I-M12 can operate in a harsh industrial environment.
