Best I can tell it is a board that other people say they try that implements this protocol as a separate board. I am also only using the NX-8E serial port for testing this, and do not use the 584.?
If your application only uses polling (no realtime zone transition notifications enabled ) or doesn¡¯t involve sending requests to the panel, you will not notice an issue.
The most prominent manifestation of this issue is in a home where the homeowner disarms the alarm and the disarm command takes several seconds to work because it is getting ignored by the panel as the panel comms freeze while trying to tell crestron about the zones the homeowner tripped when they walk in the house.
the solution of switching to ¡°polling¡± fixes it, at the expense of seconds of delays in finding out when zones trip, and cpu time on the processor to continuously ask NX about zone status. ?This solution will be for those who need the best of both worlds with this equipment?
