Appendix E: Terminal Interface Protocol
General Description
The control panel can communicate with a remote terminal or computer
connected to the CPU-400 EIA-232 port. (Refer to Section 2, Installation,
for installation information.) Set up the EIA-232 port for interactive opera-
tion or for monitoring only. Interactive operation requires that all equip-
ment 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 moni-
toring 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, are not
isolated from earth ground. These devices should be connected to the
panel through isolation modems, because direct connection can cause a
ground fault.
Operating Modes
The AFP-400 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-400 Programming Manual.
