1.2. Configuration Parameters
The information 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
configuration server.
A channel is a logical grouping of LON to IP routers. The minimum 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.
A channel, then, is defined as a group of routers that all send information to each other. The
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). The 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. That 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
The eNodeIV 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 eNodeIV device's configuration only. The user
can change the eNodeIV device's operating information and determine to whom the router will
send information. In Manual mode the eNodeIV device will honour read requests from other
devices or configuration servers, but it will block requests to write or change internal
parameters. This is a more secure mode and may be preferred on open networks. This mode is
also preferable with non-standard configurations such as Flood Mode or DDNS.
1.3.2. 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. The configuration server sets some
