Operating Mode   

6.1.

 

Coordinator mode 

If the user configures the operating mode 4,

M0=0,M1=0

or  the user configures the operating mode as 0, the modem 

works in the coordinator mode. In the coordinator mode,  the coordinator can set up the network, coordinator is the central 
node of the network,  there must be a coordinator in the network. 

The coordinator configurable data input mode is: 
Broadcast transmission. When configured  to broadcast, all  non-dormant devices on the entire  network  will  receive 

data. The ACK pin indicates transmission successfully all  the time. 

       Short  address transmission, when  configured to short address transmission, the user must specify the short address
