1. Overview
1.1. Introduction
eGRouter (GR4) router supports two open standard protocols, namely ANSI/EIA 709.1 and
ANSI/EIA 852. Both the ANSI/EIA 709.1 and ANSI/EIA 852 are dened by the Consumer
Electronics Association Technology & Standards R7.1 HCS1 Subcommittee. For more details see
http://ce.org/.For the sake of brevity the remainder of the document will refer to the
standards as 709.1 and 852. 709.1 is also known by its trademarked name, LonTalk®. A 709.1
network is also commonly referred to as aLocal Operating Network or LON. is document will
use 709.1 network and LON interchangeably.
e852 protocol acts as the transport service to convey 709.1 messages over Internet Protocol (IP)
networks. is technique of using another protocol (i.e. 852) to transport a message over an
alternate media is oen referred to as tunneling.In 852 parlance the tunneled protocol is a
Component Network (CN) protocol. e852 protocol is a generic tunneling protocol and is not
limited to 709.1. However, a particular implementation of the 852 protocol may only support the
tunneling of a single CN protocol. etunneled CN messages have no information or awareness
of the tunneling process. Although some of the gures in this document use CN or CN/IP to
represent a component network or component network to internet protocol connection, the only
CN currently supported by the GRouter device is 709.1
A component network protocol is oen called a eldbus due to its use for machine to machine
networking and control in the eld.is document, however, will only use the term component
network or CN.
852 not only provides the vehicle to transport ANSI 709.1 messages across IP, but it also provides
management of these connections or routes. A logical grouping of 852 devices that exchange
packets is called an 852 channel. One may think of an 852 channel as a kind of virtual LAN on an
IP network.
A GRouter device forwards 709.1 packets to or from an IP channel (using an Ethernet or WiFi
transceiver) and a CN channel (using twisted pair FT-10 or RS-485 transceivers). eGRouter
device has a presence on, or physical connection to, both channels. erouter takes 709.1
messages from the component network, wraps them in an 852 packet and sends them over the IP
network. eGRouter device also receives 852 packets on its IP interface, unwraps them and puts
the 709.1 messages on the CN channel. evirtual 852 channel looks like a CN channel to CN
nodes. eIP element is transparent. is enables a at network and is more easily managed and
scaled than using CN to IP interfaces that do not hide the IP element from the CN nodes. e
important thing is not what the CN to IP device is called but how transparent it makes the IP
network appear to the CN nodes.
Network connection devices can operate at different layers of particular networks protocol stack.
709.1 is an OSI 7 Layer type protocol. Whereas the Internet Protocol has only 4 layers. (See Figure
Figure 2.1 for a diagram of the different layers of the two protocols.)
-7-

Fig.1.1: Network Layers
A network connector is a device that joins different parts of a network. Connectors have a specic
name that is dependent on the layer at which the connector operates. For example a router
operates at the network layer and a gateway at the application layer. Because higher layers of the
protocol do not have access to some of the information stripped away by lower layers, network
connectors operating at different layers have different capabilities. ere is also some abuse of
terminology so that the descriptions of network connectors from different manufacturers may be
confusing. For example, a repeating router may be called a repeater for short. Although a
repeating router acts similarly to a physical layer repeater, it operates at the network layer and is
not equivalent. It is usually best to nd out at which layer a network connector operates.
Fig.1.2: Network Connector Types and Associated Layers
eGRouter device is amore complex connector because is connects two different protocols and
also connects the protocols at different layers. On the IP side the GRouter device operates at the
application layer and so is appropriately called an IP Gateway. On the 709.1 side the GRouter
device operates at the network layer and is appropriately called a 709.1 router. So depending on
the user’s perspective the GRouter could be called a gateway or router or a router/gateway. (See
Figure 2.3)
-8-

Fig.1.3: CN to IP Router/Gateway Architecture
e GRouter device also employs a web server for conguration purposes. (See Figure 2.4)
Fig.1.4: GRouter 3 Architecture
1.2. Conguration Parameters
einformation required for successful ANSI/EIA 709.1 transport can be broken up into the
following two categories: device parameters and channel parameters.
Device parameters include information such as: IP address, IP port, Name, and Address of
conguration server.
A channel is a logical grouping of LON to IP routers. eminimum requirement for tunneling
ANSI/EIA 709.1 data is the use of two routers. Router A sends data to Router B and vise versa.
However, routers can also send data to more than one router. In such a case, Router A sends data
to Routers B, C, and D, which in turn send data back.
-9-

A channel, then, is dened as agroup of routers that all send information to each other. elines
of communication are open in both directions and to all members—a complete mesh of
connections.
Typically, channels are managed through the use of a conguration server (called Normal mode
see below). econguration server informs all members in the channel about the channel
information, which includes the adding and removing of channel members. Conguration
servers are capable of managing multiple channels, while routers belong to only one channel at a
time.
Lon to IP routers can also be managed manually by conguring each device uniquely (called
Manual mode, see below). In such a manual conguration, for proper operation, devices must
have mutual membership in each other’s channel lists. at is if Device A is in Device B’s channel
list then Device B must be in Device A’s channel list. However if Device C is in Device B’s channel
list, Device C does not have to be in Device A’s channel list.
1.3. Modes of Operation
e GRouter device can operate in one of two modes: (1) Manual, (2) Normal.
1.3.1. Manual Mode
In Manual mode the user has control over the GRouter device's conguration only. euser can
change the GRouter device's operating information and determine to whom the router will send
information. In Manual mode the GRouter device will honor read requests from other devices or
conguration servers, but it will block requests to write or change internal parameters. is is a
more secure mode and may be preferred on open networks. is mode is also preferable with
non-standard congurations such as Flood Mode or DDNS.
1.3.2. Normal Mode
Normal mode allows the user to view conguration data and channel data set by a remote
conguration server such as an i.LON® conguration server. econguration server sets some
of the operating parameters of the GRouter device. Conguration servers mostly manage the
device's channel. echannel is made up of other devices to which the GRouter device will
tunnel or send ANSI/EIA 709.1 data. In Normal mode the adding and deleting of devices is
managed exclusively by the assigned conguration server. econguration server provides a
single interface to add and delete devices. Finally, Normal mode permits read access to
information by other devices and write access to information for the assigned conguration
server.
Note: Echelon’s LNS based VNI interface (LonMaker) only works in Normal mode. In order for a
GRouter device to communicate directly over an IP channel to a VNI interface requires that the
GRouter device be in Normal mode.
1.4. Applications of the GRouter Device
1.4.1. Multi-site building automation networks
einterfaces described here provide the management necessary for the ANSI/EIA 852 to tunnel
ANSI/EIA 709.1 packets successfully over IP. is ability provides wide area network (WAN)
-10-

support to ANSI/EIA 709.1 networks. is allows multi-building or multi-site connection of
automation networks.
Internet
Fig.1.5: Multi-site building automation network with internet connectivity
1.4.2. IP backbones for LON traffic aggregation
Furthermore, since the IP networks can support much higher traffic capacity, GRouter devices
can also be used to aggregate 709.1 trafficfrom several LON channels over one IP channel. e
ability to aggregate larger traffic volumes allows several GRouter devices and other 709.1 to IP
routers to be used as network backbones for 709.1 networks.

1.4.3. Roaming Connections
Finally, LON to IP gateways may be connected to specialized IP applications instead of to other
gateways. Connecting an IP application to a GRouter device provides these specialized
applications with roaming capabilities which would be difficult if these applications were required
to be directly connected to the 709.1 network (e.g., GadgetAnalyzer, LonMaker-3, etc.). An
example of how several GRouter devices can be interconnected to support an IP backbone for
several LON networks is show in Figure 2.5.
1.5. IP Addressing Modes
eGRouter device uses one of two forms of IP addressing: unicast and multicast. Multicast
currently only works when in manual mode.
eadvantage of multicast is that for networks with multiple Gateways (especially in ood
mode), multicast may be more efficient. edisadvantage of multicast is that some internet
routers do not support it. Multicast mode can reduce the IP trafficrelative to unicast when there
are alarge number of 852 devices in the channel. Up to 255 devices per IP domain are supported
with multicast. Some older IP routers do not support multicast and therefore you will not be able
to route 852 packets across a unicast only router with multicast addressing. IP router support for
-12-

Multicast is not a concern when all the 852 devices share the same subnet. efollowing gures
illustrate the differences between multicast and unicast.

2.1.1. Ethernet
For Ethernet equipped GRouter devices, rst congure the host computer to add an IP interface
on subnet 10.0.2.0/255. Connect one end of a Cat5 Ethernet cable to the RJ-45 on the GRouter
device and the other end to an Ethernet hub or switch or directly to a computer with a crossover
cable or straight through if the computer’s Ethernet port supports auto crossover (Auto MDIX).
eGRouter Ethernet port is MDI only. In cases where the LAN does not support the default
subnet, a direct connection between the GRouter device and the web browser host computer will
be needed.
