The U60 DIN Network Interface is a compact network interface for LON/IP and LON twisted pair communications. Three models are available: one for FT (ISO/IEC 14908-2 TP/FT-10) channels, one for TP-1250 (TP/XF-1250) channels with standard noise immunity, and one for TP-1250 (TP/XF-1250) with high noise immunity but with installation restrictions. The U60 FT provides a USB interface for attaching to a host computer, controller, or router.  The U60 FT and the two U60 TP-1250s provide an interface for attaching to an EnOcean SmartServer IoT. The U60 DIN Network Interfaces are packaged in a DIN 43880 2TE compliant enclosure.

You can use multiple U60 DIN Network Interfaces with hosts such as the SmartServer IoT that support multiple channels. When you attach multiple network interfaces to a host, each U60 provides an interface to a single twisted-pair channel. You can add up to four U60 FT interfaces and one U60 TP-1250 interface to a SmartServer IoT to support routing of up to five twisted-pair LON channels. To attach more than four USB interfaces to a SmartServer, add a powered USB hub to support additional USB interfaces.

The U60s have two protocol modes of operation—Layer 2 mode and Layer 5 mode that can be selected by the host application. 

  • In Layer 2 mode, the U60 implements Layers 1 and 2 of the ISO/IEC 14908-1 and 14908-2 protocol and is compatible with the LON/IP stack included with the IzoT SDK. The LON/IP stack provides source code for LON/IP and classic LON compatible protocol stacks. 
  • In Layer 5 mode, the U60 implements Layers 1 through 5 of the ISO/IEC 14908-1 and 14908-2 protocol and is compatible with EnOcean's previous generation Microprocessor Interface Program (MIP) products.

A Service LED indicates the network status of the U60, with Rx and Tx LEDs providing an indication of packet reception and transmission.

The U60 DIN is powered through its USB interface.
