Channels and Communications Parameters
The network services tools being used for network configuration must
contain channel definitions for each physical subnet in a LonWorks net-
work. The communications parameters of these channels should match the
transceiver type that they will be attached to. These channels are assigned
to nodes and routers in the network services tool which uses this informa-
tion for two purposes:
• To determine the network topology and calculate timing for mes-
sages sent between nodes.
• To set the transceiver parameters of each node and router during
installation.
The RTR-10 Router Core Module in the ROUTER-LL has two transceiver
interfaces. The transceiver that connects to the LONTALK connector
(LonTalk side) of the ROUTER-LL is either a TP/FT-10, TP/XF-78, or TP/
XF-1250 transceiver depending on which model you have purchased. The
transceiver that connects to the ETHERNET (IP side) of the ROUTER-LL
is a Special Purpose transceiver.
The communications parameters for a standard transceiver (TP/FT-10,
TP/XF-78, or TP/XF-1250) should be used for the LonTalk side of the
ROUTER-LL. The data in Appendix B: Communications Parameters
should be used to define the channel that connects to the IP side of the
ROUTER-LL. For those network services tools that can use them, Router
Interface files (RIF files) are supplied on the ROUTER-LL Companion
Disk for each of the three ROUTER-LL transceiver configurations (TP/
FT-10<->Special Purpose, TP/XF-78<->Special Purpose, and TP/XF-
1250<->Special Purpose).
If the wrong communications parameters are loaded into the RTR-10
Module, the router may be unable to communicate through its transceiv-
ers. The communications parameters for the LonTalk side of the
ROUTER-LL are hard coded to the correct values. If these values are set
incorrectly by a network services tool, they will be reset the next time the
ROUTER-LL is power cycled. The communications parameters for the IP
side must be set correctly by the network services tool or the ROUTER-LL
will not function correctly.
NOTE : If the communications parameters of the IP side of the ROUTER-
LL are corrupted for some reason, the network services tool must be con-
nected to the LonTalk side to set the correct values (since communications
will not be possible through the IP side until the parameters are set cor-
rectly).
