Why is the BAD CRC counter incrementing every minute on my Honeywell Security System?
If the BAD CRC counter is incrementing every minute on your Honeywell Security System, it means that two or more panels on the Multidrop Bus have the same panel address. To resolve this, verify that each panel has a unique address setting on DIP switch positions 1-5.
Why does my Honeywell Security System have no communications with the Ethernet port?
If there are no communications with the Ethernet port on your Honeywell Security System, only a panel set to be a Gateway (DIP switch 6 = ON) will have communications on the Ethernet port. If you need to use that port to access the panel, turn off the power (including the battery), change the switch setting, and reapply the power. Note that if the panel is normally not a Gateway on a Multidrop communication bus, then the Host RS-485 connection (TB7) should also be disconnected while DIP switch 6 is ON. After completion of the Ethernet session, turn off the power (including the battery), change the switch setting, re-connect the Host RS-485 terminal block, and re-apply the power.
What to do if Honeywell Security System panel powers up but does not respond?
If your Honeywell Security System panel powers up but doesn't respond to communication, card reads, or input activation, ensure that the Address DIP switches are set to a value other than zero. Turn off the power (including battery), change the settings, and re-apply the power.
Why are the N1000 panels on the Multidrop bus not reporting on my Honeywell Security System?
If the N1000 panels on the Multidrop bus do not report on your Honeywell Security System, it is because N1000 panels will not communicate to a NetAXS™ panel that is configured as a Gateway. Replace all of the N1000 panels with NetAXS™, or replace the Gateway panel with an N-485-PCI-2 device.
What to do if a dropline panel in standalone mode unexpectedly fills its buffer on my Honeywell Security System?
If a dropline panel in standalone mode using RS-232 unexpectedly fills its buffer in your Honeywell Security System, the preferred solution is to configure the standalone panel through the Web server as a Gateway and use the board PCI and AckNak communications. This also gives the user a more secure and reliable communications line. Another solution is to execute a new command that will allow the user to turn the Tesla flow control off: _U=_D (disable flow control). To turn the Tesla flow control back on: _U=_E (enable flow control)
Why does the BAD CRC counter increment every minute on my Honeywell Control Unit?
The BAD CRC counter increments every minute because two or more panels on the Multidrop Bus have the same panel address. To resolve this, verify that each panel has a unique address setting on DIP switch positions 1-5.
How to enable communications on the Ethernet port of my Honeywell NETAXS NX4L1?
Only a panel set to be a Gateway (DIP switch 6 = ON) will have communications on the Ethernet port. If you need to use that port to access the panel, turn off the power (including the battery), change the switch setting, and reapply the power. Note that if the panel is normally not a Gateway on a Multidrop communication bus, then the Host RS-485 connection (TB7) should also be disconnected while DIP switch 6 is ON. After completion of the Ethernet session, turn off the power (including the battery), change the switch setting, re-connect the Host RS-485 terminal block, and re-apply the power.
How to prevent a Honeywell Control Unit drop line panel in standalone mode from filling its buffer?
The preferred solution is to configure the standalone panel through the web server as a Gateway and use the board PCI and AckNak communications. This also gives the user a more secure and reliable communications line. Another solution is to execute a new command that will allow the user to turn the Tesla flow control off: _U=_D (disable flow control). This prevents the panels from inadvertently filling their buffers. To turn the Tesla flow control back on: _U=_E (enable flow control).
Why N1000 panels on the Multidrop bus do not report to my Honeywell Control Unit?
N1000 panels will not communicate to a NetAXS panel that is configured as a Gateway. Replace all of the N1000 panels with NetAXS, or replace the Gateway panel with an N-485-PCI-2 device.
