NFS-640 Operations Manual P/N 51334:B 10/03/2003 67
Appendix C: Remote Terminal Access
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-640 Installation Manual for installation information.
Note: See the NFS-640 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) listed equipment is allowed for ancillary system monitoring
when the system is installed and set up as directed under Remote Terminal Mode (RemT). You can also
use Outlasted equipment for system servicing or programming.
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-640 Programming Manual.
The following subsections outline the functions, password requirements, and additional information for
each operating mode.
