NetAXS™ NX4L1 Installation Guide
System Configuration
5.0 System Configuration
This section provides wiring diagrams for each of the NetAXS system configurations.
5.1 RS-485 Connection via PCI-2
This connection supports thirty-one NetAXS Access Controller panels for each drop line. Note that
PCI-2 units can also be wired in interior, as well as in endpoint, positions. See
on page 45. Because UL has approved the NetAXS panel only as a standalone system,
the computer terminal, NetAXS gateway panel, and N-485_PCI-2 adapter appear in these sections
only to illustrate the installation and programming of the NetAXS panel.
