FEEDBACK
Ensure the Panel TX connection is made to the RX of the RS232 controller.
When a Master Panel receives the First command it will return an Acknowledge code: ECh.
It will then perform the programmed Button script. When it has completed the last event
of the script it will return a script Finished code: F0h 17h
20h.
The Panel will wait until it receives the second command.
If the system is being used without any feedback then a delay must be added between the first and second
command until the Panel has completed the script. The Panel will be disabled until it receives the second
command.
