General Description Terminal Interface Protocol

Appendix I Terminal Interface Protocol
I.1 General Description
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 (RemM). 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.
I.2 Operating Modes
The control panel provides three operating modes for the EIA-232 port, Local Terminal
(LocT), Local Monitor (LocM), and Remote Monitor (RemM). You select the operating
mode during control panel programming (system parameters). For more information,
refer to Section 3 “Programming”.
The following subsections outline the functions, password requirements, and additional
information for each operating mode.
I.2.1 Local Terminal Mode (LocT)
Functions, passwords, and special requirements of Local Terminal Mode (LocT) are:
Functions: Read Status, Alter Status, and Control Functions.
Passwords: User-defined password for Alter Status functions.
Requirements: The terminal must be mounted in a UL-864 listed enclosure, a
Notifier Rack-51, Rack-67, or positioned to provide equivalent
protection against unauthorized use.
