Appendix C: Remote Terminal Access
C.1 General Description
The control panel can communicate with a remote terminal or computer connected to the EIA-232
PC/Terminal port. Refer to the NFS-320 Installation Manual for installation information.
NOTE: See the NFS-320 Programming Manual for instructions on enabling the CRT.
This port may be set up for interactive operation or for monitoring only. Interactive operation
requires that all equipment be UL-listed under UL Standard for Safety UL 864 and be installed and
set up as directed under Local Terminal Mode (LocT) or Local Monitor Mode (LocM).
ITE (Information Technology Equipment) equipment listed under UL 1950 is allowed for ancillary
system monitoring when the system is installed and set up as directed under Remote Terminal
Mode (RemT).
C.2 Operating Modes
The control panel provides three operating modes for the CPU EIA-232 PC/Terminal port:
•
Local Terminal - LocT
•
Local Monitor - LocM
•
Remote Monitor - RemM
You select the operating mode during control panel programming (Global System Functions). For
more information, refer to the NFS-320 Programming Manual.
The following subsections outline the functions, password requirements, and additional
