CAUTION
The controller must be
OFF
before being connected.
6
Connect the LonWorks network to the LonWorks Option Card's 2-pin
Net
port.
NOTE
The 2-pin
Net
port provides TP/FT-10 channel compatibility. The TP/FT-10 or "Free Topology" network
type is
polarity insensitive
. Use 24 to 16 AWG twisted pair wire.

Turn on the power for the Unit Vent by connecting power terminals.

Commission the controller for LonWorks communication. See instructions below.
Commissioning the controller for LonWorks communication
Before a device can communicate on a LonWorks network, it must be commissioned. Commissioning allows the
system integrator to associate the device hardware with the LonWorks system’s network layout diagram. This is
done using the device’s unique Neuron ID.
A network management tool such as Echelon’s LonMaker is used to commission each device, as well as, to assign
addressing. Specific instructions regarding the commissioning of LonWorks devices should be obtained from
documentation supplied with the LonWorks Network Management Tool.
When a new device is first commissioned onto the LonWorks network, the system integrator must upload the
device’s External Interface File (XIF) information. LonWorks uses the XIF to determine the points (network
variables) that are available from a device. The Unit Vent has a set of predefined network variables. These
variables can be bound or accessed by the Network Management Tool.
The
Browse
feature of the Network Management Tool allows you to read real-time values from the Unit Vent. The
Network Management Tool allows you to test integration prior to binding the controller's network variables to other
LonWorks nodes.
