The control panel can communicate with a remote terminal or computer connected to
the CPU EIA-232 port. (Refer to Section 2,
Installation
, for installation information.)
Set up the EIA-232 port for interactive operation or for monitoring only. Interactive
operation requires that all equipment be UL-listed under UL Standard for Safety UL864
and be installed and set up as directed under Local Terminal Mode (LocT) or Local
Monitor Mode (LocM). EDP listed equipment is allowed for ancillary system
monitoring when the system is installed and set up as directed under Remote Monitor
Mode (RemT). You can also use EDP-listed equipment for system servicing or
programming.
The EIA-232 ports on some terminals/computers, including the CRT-2, are not isolated
from earth ground. These devices should be connected to the control panel through
isolation modems, because direct connection can cause a ground fault.

The control panel provides three operating modes for the EIA-232 port, Local
Terminal, Local Monitor, and Remote Monitor. You select the operating mode during
control panel programming (system parameters). For more information, refer to the
AFP-300/AFP-400 Programming Manual.
The following subsections outline the functions, password requirements, and additional
information for each operating mode.
