6. Connection to the LonWorks

The physical connection to the LonWorks

with removable terminals fitted on the board, according to the Echelon

and specifications. For further information on installation, maintenance, the cross-

section and type of cable, refer to the LonWorks

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.
