1. Introduction
The dap4 LonWorks card (Data Aire P/N 160-700-020) is an optional network card
which allows the dap4 controller to be connected directly to a LonWorks®network.
The use of these boards requires knowledge of and experience with the LonWorks®
network installation and maintenance tools. The LonWorks card can be factory
installed or field installed.
2. Physical channels
The LonWorks card uses an Echelon®FTT-10 transceiver, approved for use on the
TP/FT-10 channel.
This channel has the following main characteristics:
Alllowing the connection of a maximum of 64 nodes for each network
segment;
The nodes can be connected without any restrictions in the topology: that is,
star, ring, on one bus only, or with any combination of these.
Communication speed: 78,125 kbps;
Maximum distance (Belden 85102 cable): 500m for connections between the
nodes with free topology.

For details on the activation of the service pin, see Connection to the LonWorks®network.
4. Meanings of the LEDs
The green service LED:
Signals the status of the node, as per the LonWorks®protocol:
Hardware fault: always ON or always OFF;
Node configured (normal operation): ½ second ON, then always OFF;
Node NOT configured: flashing at ½ Hz;
Node without software application: 1 second ON, 2 seconds OFF, then always OFF;
Node in continuous reset: flashing;
Remains on during the activation of the service pin;

Remains on for one second when receiving a wink command via the network
(see Connection to the LonWorks® network).
The red fault LED:
Signals problems in the connection between the board and the dap4 controller.
WARNING
If the red LED comes on, make sure the instructions described under Installation have
been carefully followed. Network address must be greater than 1 (Use screw driver and
press button next to J3 connector to display the network address) and protocol must be
set to Lon on dap4 network config menu.
5. Installation
IMPORTANT WARNINGS: precautions in handling the board. Electrical damage
may occur to the electronic components as a result of electrostatic discharges from
the operator. Suitable precautions must be therefore be taken when handling these
components, specifically:
Before handling any electronic component or board, touch an earthed object
(simply not touching the component is not enough to prevent a spike, as static
electricity can produce a 10000V discharge, which can form an arc of about
1cm).
All materials must be kept inside their original package as long as possible. If
necessary, take the controller from its package and place it into antistatic
packaging, without touching the back of the board;
Absolutely avoid non-antistatic plastic bags, polystyrene or sponges;
Do not pass the electronic components or boards directly to other operators (to
prevent electrostatic induction and discharges).
Connect Lonworks card to the dap4 or Mini-dap4
With reference to Figs. 2- 5 below, insert the board in the dap4 or Mini-dap4 as
follows:
1. Disconnect the power supply to the controller.
2. Using a screwdriver, remove the BMS card cover (serial card cover on Mini-
dap4) (see Fig. 2).
3. With cutting nippers, remove the pre-cut plastic part from the cover, thus making
the opening for the 3-pin connector (see Fig. 3).
4. Insert the LonWorks card in the corresponding plug-in connector, initially holding
it diagonally and then making sure it is properly inserted and pushed up against
the two plastic supports on the case of the dap4 (see Fig. 4);
5. Close the cover again, aligning the connector on the card with the hole made in
the cover (see Fig. 5).
6. Reconnect the power supply to the controller; if the BMS 1 communication port
has been set to use the Lon protocol, the red LED on the board will come on for
a few seconds and then will go off immediately, indicating correct operation.

6. Connection to the LonWorks®network
The physical connection to the LonWorks®network is performed using the connector
with removable terminals fitted on the board, according to the Echelon®instructions
and specifications. For further information on installation, maintenance, the cross-
section and type of cable, refer to the LonWorks®literature.
Important Note: Data Aire Dap4 Lon interface uses a Carel Lonworks card; if there is
existing equipment provided by others that uses the same Carel Lonworks card then
the device interface file (XIF) of dap4 must be manually loaded during the
commissioning process otherwise Lon network may use an incorrect device interface
template on dap4 that leads to erroneous data.
Service pin
To activate the service pin, simply momentarily short-circuit the two pins on the
board (see Fig. 1 and no.3) with the tip of a screwdriver or a similar tool.
The service pin must only be activated during the installation of the node. When
the pin is activated, the node sends a broadcast message over the LonWorks®
network, containing the information required for identification. There is sticker on
the card to indicate the Lon card neuron ID, this neuron ID can be used to
manually commission the card if service pin does not work.
After you can commission the card and the red LED is lit, reset the dap4 (power off then
back on). The Red LED should go off after dap4 starts up. If dap4 does not get reset
after commissioning, the erroneous data may appear.
WINK event
A generic supervisor can send the WINK command to a specific node on the
LonWorks®network. This generates an event that the application on the specific
node can respond to with any action decided by the programmer.

In this specific case, the service LED on the interface comes on for one second,
thus making it possible to check the correct operation of the connection between the
interface and LonWorks® network.
7. XIF and NXE file for dap4
The XIF and NXE for dap4 can be downloaded from Data Aire website for
commissioning the dap4.
http://www.dataaire.com, go to System Controls/ dap4.
8. dap4 LonWorks Point list
Note: Read = NVO, write = NVI, some parameters can be read and written, in this
case these parameters have separate NVO point for read (monitor) and NVI point for
write a new value.
