Communication Speed
(The Interval Time of Sending Broadcast Frame):
The data payload of ZT‐2000 series modules is 79 bytes. Once the data is more than 79 bytes,
it will be divided into several packets. This parameter is used to decide the interval time of
sending broadcast frame in order to prevent the network crashes. Please fill in the number of
ZT‐2000 slaves nearby the ZigBee Coordinator.
