SA-HT640WPL
How can Master or Slave setting be selected? By software or hardware?
It can be selected by external control pin.
How long does it take to transmit single packet?
To establish communication channel properly, hopping frequency and Syncword of each packet should be determined by Device
ID(Identification). Device ID is unique value of each device, master and slaves. Only master and slaves with same Device ID can
communicate each other. Device ID can be set manually in case selected master and slaves do not communicate together. This
procedure is *Device ID set*. Device ID set procedure occurs when master and slave devices boot simultaneously with ID_SET=1.
In this procedure, the slave can figure out the Device ID of the master and store it in external EEPROM. When ID_SET is
established, S5G3000 performs ID send/scan to send Device ID of master to slave before general page operation. In normal mode,
communication is accomplished by going into page state directly without ID send/scan.
How can the Master and Slave units be paired to prevent mix-up?
It takes 2.5ms.
