EN50155 Industrial 4-port secure serial to Ethernet device server with 4xRS-422/485(2KV isolation) and 1x10/100Base-T(X), M12 connector

TDS-5041-I-M12 is a secure 4-port RS-422/485 to 1 port Ethernet secure device server, with multiple operation modes: Virtual Com, Serial Tunnel, TCP Server, TCP Client, and UDP. In addition, the Windows untility, DS-Tool, could configure multiple devices and set up the mappings of Virtual Com easily. The features of NAT Router Pass Through, DDNS, and PPPoE make it more convenient for administrators to configure ORing’s device servers through NAT router from different IP domains or Internet via modem remotely. TDS-5041-I-M12 can simultaneously transfer data up to 5 redundant host PCs. Further, TDS-5041-I-M12 features HTTPS, SSH, and SSL encryption to assure the security of critical data transmission.
TDS-5041-I-M12 supports 4xRS-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. With wide operating temperature, -40~70°C, TDS-5041-I-M12 could operate in the harsh industrial environment.
