GENERAL DESCRIPTION
The GEM-RS232 Control Panel/ Computer Converter is
an interface module which allows the NAPCO GEM-P9600
control panel to be connected to a computer which may be
used to display system status. The GEM-RS232 is
approved by Underwriters Laboratories for supplemental
use only. It provides signal and ground isolation between
the control panel and the computer and will protect the
control panel from shorts, transients and surges which may
emanate from the computer or the associated cabling.
The GEM-RS232 has been designed to be permanently
mounted inside the cabinet of the GEM-P9600 and can be
connected to the computer in several different fashions
(see CONNECTION).
