Service pin
To activate the service pin, simply momentarily short-circuit the two pins on the board (see
Figure 24) 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.
