Network Adapter
Although network connections are polarity insensitive, it is good practice to keep polarity consistent
throughout the entire site. Figure 4 shows a network connection example and the location of the Status LED.
This Status LED may help to troubleshoot network problems.

Table 2 shows the different possibilities with the Status LED behavior of the LON module.
Condition of the Status LED
Explanation
Continuously ON
The Echelon communication module has no valid application
loaded in its memory.
Flashing at a rate of 1/2Hz
The Echelon communication module has an application
loaded in its memory but is Unconfigured. When an Echelon
communication module is in the unconfigured state, the
application is not running. This is the default state when the
devices are shipped. A network management tool should be
used to configure the module and integrate the device to a
LonWorks network.
Continuously OFF
The Echelon communication module has an application
loaded into its memory and the application is running.

Software Files
XIF:
When binding a node onto the network, an XIF file is needed. The XIF file has information that is used
by the network management tool to help ease the installation and maintenance process of a node. It is also
used for offline configuration of the node.
APB and NXE:
When running an application program associated with a XIF file, an APB or NXE file is
needed. Please note that the thermostats have the APB file already flashed from the factory.
Device Resource File (DRF):
When a LON network management tool is used; a DRF file must be installed.
DRF files are needed to display special manufacturer defined variables or configurations correctly.
