3.2. Network topology and channel length
The maximum wiring length for channel segment depends on the network topology and cable type.
The
maximum wire length values for channel could be increased by using the TP/FT-10 repeaters to connect
two channel segments.

Use only the dedicated terminators - one terminator in free topology and two terminators on both ends
of network channel in bus topology. In case of any question, please contact technical support
.
3.3. Integration in the LonWorks network
It is recommended that the process of integration of the LonWorks option module (setting the logical address
and state of device as Configured and Online or defining the bindings between the network variables of
another LonWorks devices) was performed by trained personnel, using dedicated tools, such as Echelon
OpenLNS Commissioning Tool software or other LonWorks platform based on Echelon LonWorks Network
Services (OpenLNS) or fully compliant the ISO/IEC 14908 (EN14908-1, CEA-709) standards.
The integration of the LonWorks module should be performed using the eXternal Interface File (XIF File)
which describe the LonMark device interface of module (like network variables used by the option module)
in format supported by the network integration tool. The XIF File and the LonMark Resource Files used to
integrate the option module in the LonWorks network are available to download from
sensus.com website.
