Appendix B. TROUBLESHOOTING

Appendix B.1. Connection Tips & Hints

Communication errors will be experienced if the port is disabled at the panel. Please check the
Notifier Manuals on how to enable the panel port connected to the FieldServer and ensure that it
is set to 80 columns NO supervision.

If connecting the Panel to one of the FieldServer RS-232 ports causes the FieldServer to reboot,
then an Optical Isolator is required to balance ground potential problems.

Appendix B.2. Networking Tips


By default FieldServer does not take any action on receiving a "SYSTEM RESET". Normally
when a Node initiates "SYSTEM RESET" by pressing the "RESET" button on the Panel, the panel
sends an individual "CLEAR" message for every point, it clears in its memory area.
FieldServer therefore waits for the "CLEAR" message to clear a specific bit in its memory for a
particular Node or for the "SYSTEM NORMAL" message to clear all bits in its memory for every
Node. Use Clear_on_Reset parameter if required.

It may be advisable to configure the Notifier panel to suppress less important "Supervisory" or
"Trouble" messages which could prevent the generation of "SYSTEM NORMAL" messages.
Consult Notifier for this configuration or recommendation.

Ensure that every Node is working with a printer or HyperTerminal, before calling FieldServer for
Support.
