5.4 RS-232 Connection
This connection supports one NetAXS™ Access Controller panel for each COM port. It has been
reviewed by UL. However, because UL has reviewed 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.
