5.2 RS-485 Connection via NetAXS

This connection supports thirty-one NetAXS Access Controller panels for each drop line. However,
because UL has approved the NetAXS panel only as a standalone system, the computer terminal and
NetAXS gateway panel appear in this illustration only to show the installation and programming of the
NetAXS panel.
