Introduction
Thank you for purchasing the Coactive ROUTER-LL LonTalk Ethernet
Backbone Router. The ROUTER-LL provides LonTalk routing capabilities
between LonWorks twisted pair media and Ethernet. As shown in Figure
1, the ROUTER-LL allows an IP network to be used as a backbone to con-
nect LonWorks subnets together.
Figure 1 ROUTER-LLs Providing an IP Backbone
This document explains how to install and configure your ROUTER-LL.
The ROUTER-LL comes in three versions, corresponding to the three
twisted pair LonTalk transceivers available:
• RTLL-EN-00007 (TP/XF-78)
• RTLL-EN-00001 (TP/XF-1250)
• RTLL-EN-0000F (TP/FT-10)
The ROUTER-LL is a fully compatible LonWorks Router. In order to use
the ROUTER-LL, you must understand LonWorks routing concepts and
be able to install a router using a network services tool (e.g. LonBuilder or
LonMaker).

Getting Started
Follow these step by step instructions to install your ROUTER-LL on
your IP network.
Configure the terminal
Connect a VT100 or ANSI terminal to the RS232 connector on the
ROUTER-LL. Configure the communications port of the terminal for EIA-
232 asynchronous serial communications at 9600 baud, 8 data bits, 1 stop
bit, no parity, and no flow control.
Establish Communications
Connect the power cord between the ROUTER-LL and an AC outlet and
flip the power switch to the on (|) position. The green POWER LED
should turn on.
After a few moments and some brief messages, the SETUP screen will
appear (note that the version number may be different):
COACTIVE AESTHETICS ROUTER-LL VERSION 2.0.1
SETUP
Mode: CLIENT
Transceiver: 10BASE-T
IP Address: 0. 0. 0. 3
Subnet Mask: 255.255.255. 0
Gateway Address: 0. 0. 0. 1
Server Address: 0. 0. 0. 2
If nothing appears on the terminal screen, recheck the cabling between
the ROUTER-LL and the terminal. If characters appear on the terminal
screen but they don’t resemble the screen shown above, recheck the com-
munication and terminal emulation settings on your terminal. You may
need to press the space bar to refresh the screen if you make any changes
to your cabling or terminal settings.

6
Configure the ROUTER-LL IP Side
Use the <RETURN> key to edit a field in the SETUP screen and the <TAB>
key to move from field to field.
Set the Mode field to either CLIENT or SERVER. There should be exactly
one SERVER in each group of ROUTER-LLs that will talk to each other.
All other ROUTER-LLs should be configured as CLIENTs.
Set the Transceiver field to match the physical Ethernet transceiver
type you will be using (10BASE-T or 10BASE2).
Consult your System Administrator to determine what IP Address,
Subnet Mask, and Gateway Address to assign to the ROUTER-LL
and configure these settings.
If you have configured the ROUTER-LL as a CLIENT, you will need to set
the Server Address fields to the IP address of the SERVER ROUTER-
LL.
When you are done configuring the ROUTER-LL, press <S> to save the
configuration. After a moment, the IP ADDRESS CONFIGURATION
screen will appear (note the version number and configuration settings
may be different):
COACTIVE AESTHETICS ROUTER-LL VERSION 2.0.1
Mode: CLIENT
Transceiver: 10BASE-T
Connections: 0
IP ADDRESS CONFIGURATION
Local: 192.190.120. 3
Subnet Mask: 255.255.255. 0
Gateway: 192.190.120. 1
Server: 192.190.120. 2
WARNING
If you assign the ROUTER-LL an IP address that is already in
use, you may cause system-wide network problems. Always
consult your System Administrator before attaching anything
to your IP network.

7
Attach your IP network cables
Connect your Ethernet network using the 10BASE2 or 10BASE-T ETHER-
NET connector on the ROUTER-LL. Be sure that you configured the
ROUTER-LL for the correct transceiver type in the previous step.
After a minute or two, the ROUTER-LL will connect to all the other
ROUTER-LLs that share the same SERVER. The Connections line indi-
cates how many connections exists to other ROUTER-LLs.
LonWorks Configuration
Before using your ROUTER-LL, you must add it to your LonWorks net-
work. The following chapter describes this process in detail.

8
LonWorks Configuration
Correctly configuring the routers in a LonWorks network is critical to net-
work operation. Taking the time to read and understand this section com-
pletely is required to successfully install your ROUTER-LL. The
ROUTER-LL will not function correctly if it has not been installed prop-
erly.
Introduction
The ROUTER-LL contains an Echelon RTR-10 Router Core Module which
provides the ROUTER-LL with full LonWorks Router functionality. Rout-
ers connect two communications channels and route LonTalk messages
between them. In a ROUTER-LL, one of these channels is always a IP
Channel. The other channel can be either TP/FT-10, TP/XF-78, or TP/XF-
1250.
Figure 2 illustrates a typical ROUTER-LL installation with a TP/FT-10
and a TP/XF-78 channel connected using a ROUTER-LL IP Channel.
Because of the routers, the applications on all four nodes in this example
can communicate as if they were installed on a common channel.

The following sections provide configuration information specific to the
ROUTER-LL needed to successfully install and use ROUTER-LLs in your
network. In addition, the Appendices of this manual contain step by step
instructions for using the ROUTER-LL with some of the more popular
network services tools.

Network Services Tools
In order to use a ROUTER-LL, the user must understand LonWorks rout-
ing concepts. This information is documented in Echelon’s LonWorks
Router User’s Guide. In addition, the user must have access to, and be able
to use, a LonWorks network services tool capable of installing LonWorks
routers. Router configuration support varies greatly among the different
network services tools. While most provide the same basic functionality,
the details of the user interface and installation procedures differ from
product to product. The information given in this section is intended to
be generic across all network services tools. The user should understand
that some effort will be required to integrate this information into the par-
ticular procedures they use to configure their network.
NODEUTIL.EXE and RTR_CFG.EXE
In addition to a network services tool, it is often necessary to use a low
level LonWorks diagnostic tool to inspect and change network parame-
ters on nodes and routers in a LonWorks network. Echelon’s
NODEUTIL.EXE tool Coactive recommends that the user not use Eche-
lon’s NODEUTIL.EXE tool to change any parameters on the ROUTER-LL.
Under certain circumstances, NODEUTIL.EXE will corrupt the communi-
cations parameters on the IP side of the RTR-10 Module. Coactive sup-
plies a tool similar to NODEUTIL.EXE named RTR_CFG.EXE which is
customized for the ROUTER-LL. RTR_CFG.EXE is supplied on the
ROUTER-LL Companion Disk and is described in detail in Appendix D:
RTR_CFG.EXE.
RTR_CFG.EXE is required when installing a ROUTER-LL. This procedure
is described in detail in the following sections.
Network Address
The ROUTER-LL’s RTR-10 Router Core Module contains two Neuron
Chips. Each of these chips must be assigned one or two domain table
entries. These entries allow the Neuron to receive network management
messages, and they are also used by some routing algorithms to make
routing decisions (see Routing Algorithm, below).
The domain table entries in the ROUTER-LL are typically set by the net-
work services tool during network configuration. ROUTER-LLs are deliv-
ered from the factory with the table entries set as described in Appendix
C: Factory Setting.
