A channel, then, is defined as a group of routers that all send information to each other. e lines
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 configuration server (called Normal mode
see below). e configuration server informs all members in the channel about the channel
information, which includes the adding and removing of channel members. Configuration
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 configuring each device uniquely (called
Manual mode, see below). In such a manual configuration, 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 GR3 router can operate in one of two modes: (1) Manual, (2) Normal.

3.1. Manual Mode
In Manual mode the user has control over the GR3 router's configuration only. e user can
change the GR3 router's operating information and determine to whom the router will send
information. In Manual mode the GR3 router will honor read requests from other devices or
configuration 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 configurations such as Flood Mode or DDNS.

3.2. Normal Mode
Normal mode allows the user to view configuration data and channel data set by a remote
configuration server such as an i.LON® configuration server. e configuration server sets some
of the operating parameters of the GR3 router. Configuration servers mostly manage the device's
channel. e channel is made up of other devices to which the GR3 router will tunnel or send
ANSI/EIA 709.1 data. In Normal mode the adding and deleting of devices is managed exclusively
by the assigned configuration server. e configuration 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 configuration server.
Note: Echelon’s LNS based VNI interface (LonMaker) only works in Normal mode. In order for a
GR3 router to communicate directly over an IP channel to a VNI interface requires that the GR3
router be in Normal mode.

4.1. Multi-site building automation networks
e interfaces 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)
