LON Communication Card Connection
The FX07 controller cover displays 1, 2, and 3 as the Supervisory Link
terminals. For the LONWORKS Communication Card, the connections to
the FTT LON network appear in Table 3. The connections are not
polarity sensitive; however, we recommend that you make consistent
connections for easier troubleshooting.

LON Neuron® ID
After you press the Service Pin located on the LON communications
card (accessible through the controller cover), the FX16 controller sends
a unique Neuron ID over the LON network. There is also a label on the
LON communications card with the Neuron ID (number and barcode).
LONWORKS Network Layout
Refer to the LONWORKS FTT-10A Free Topology User’s Guide

the Echelon® Web site (www.echelon.com).
RS-232C Communications Card
You can order the FX16 controller with the RS-232C communication
card, or you can order the RS-232C communication card separately to
insert the card at a later time. See
Ordering Codes.
The RS-232C Plug-in card allows the FX16 Master Controller to
connect to a Global System for Mobile (GSM) Communications modem
or to a standard land-line modem.
