Introduction to Lightweight Ethernet

Lightweight Ethernet (LWE), defined by IEC61162-450, is a protocol defined to enable an
Ethernet connection between multiple talkers and multiple listeners, using the messages
defined in IEC61162-1/2. LWE is an IP-based implementation, making use of a multicast
address and corresponding User Datagram Protocol (UDP) port for transmission. LWE is
essentially a means to share data between units over Ethernet.
There are some restrictions on the connection of LWE networks:
• The different components are connected through an Ethernet switch, and connection to
a router or repeater hubs are not allowed
• No multicast filtering is configured
Equipment on the network that performs system functions can transmit and receive
information. Each System Function (SF) is identified by a System Function Identifier (SFI)
which is unique on any boat network.
Ú Note:
If no SFI is entered (remaining with the default 9999 value), the device will not be
visible on the LWE network, and it will not share any data.
Every device that is a part of the LWE network shall be assigned an IP address (10.0.0.1 to
10.255.255.253 or 192.168.0.1 to 192.168.255.254). This IP address is to be chosen as a unique
address for every device on the boat network.

The settings dialog

The system setup is done from the settings dialog.
Access control
Some of the parameters in the settings dialogs are intended for system setup and service
engineers. These parameters are protected, and they are only available by entering the
password QWERTY.
