Application Image tDS-715 Tiny Serial-to-Ethernet Device Server with isolation

The tDS-715i is a Serial-to-Ethernet device server with 2500 VDC isolation. It is designed to add Ethernet and Internet connectivity to any RS-422/RS-485 devices, which eliminates cable length limitation of legacy serial communication. By using the VxComm Driver/Utility, the built-in COM port of tDS-715i can be virtualized to a standard PC COM port in Windows. Users can transparently access or monitor serial devices over Internet/Ethernet without software modification.

The tDS-715i RS-485/RS-422 to Ethernet device server can create a pair-connection application as well as serial-bridge or serial-tunnel, and then route data over TCP/IP between two serial devices. It Is useful when connecting mainframe computers, servers or other serial devices that do not themselves have Ethernet capability. Protocol independence and flexibility of the tDS-715i meets the demands of virtually any network-enabled application.

For maximum space savings, the tDS-715i comes in an amazing tiny size that makes it easy to install anywhere, even directly attached to a serial device or embedded into a machine. This RS-485/RS-422 to Ethernet device server features a powerful 32-bit MCU to handle efficient network trafficking. It offers true IEEE 802.3af-compliant (classification, Class 1) Power-over-Ethernet (PoE) function using a standard category 5 Ethernet cable to be powered by a PoE switch like the NS-205PSE. When there is no PoE switch on site, the tDS-715i accepts power input from DC adapter.
