Overview
The U60 DIN Network Interface is a compact network interface for LonTalk/IP and
LON twisted pair communications. Two models are available, one for FT (ISO/IEC
14908-2 TP/FT-10) channels and one for RS-485 (TP/RS-485) channels. The U60
provides a USB interface for attaching to a host computer, controller, or router, or for
attaching to an Echelon IzoT Router. The U60 DIN Network Interface is packaged in
a DIN 43880 2TE compliant enclosure.
You can use multiple U60 DIN Network Interfaces with hosts such as the IzoT
Router 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
use up to four U60 DIN Network Interfaces with the IzoT Router to support routing
of up to five twisted-pair LON channels, one using the IzoT Router’s internal FT
network interface, and up to four additional channels with external U60 DIN
Network Interfaces.
The U60 has 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 LonTalk Device Stack EX included with
the IzoT SDK Standard and Premium Editions. The LonTalk Device Stack EX
provides source code for LonTalk /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 Echelon’s previous generation
Microprocessor Interface Program (MIP) products.
When used with a Windows computer, the mode is typically selected automatically by
the application.
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.
