System Configuration
5.4 RS-232 Connection
This connection supports one NetAXS Access Controller panel for each COM port. It has been
approved by UL. However, because UL has approved the NetAXS panel only as a standalone system,
the computer terminal and NetAXS gateway panel appear in this section only to illustrate the
installation and programming of the NetAXS panel.
