The LCD Full Segment is as below:
Users can set the parameters of the RF module such as working mode /frequency / transmitter power / transmission
data rate through the buttons, and measure the wireless communication distance.
Working Mode
1) Master Mode: Send 1 packet per second, and waiting for the acknowledge;
2) Slave Mode: Stay in Rx mode to wait for the data from the master, it will send back the acknowledged signal after
received the data from the master.
3) Tx Test Mode: RF module continuously transmit signal;
4) Rx Test Mode: RF module is always in Rx mode;
5) Standby Mode: RF module is always in standby state.
Button Operation
1) [SET] Button
Press the [SET] button to enter into setting mode; Or press the [SET] button to be out of the setting mode upon
the last parameter is done.
2) [UP/Down] Button
In setting mode, press the [UP/Down] button to increase/decrease the value of flash icon.
Note: The DEMO board has FLASH memory inside, all the setting parameters will be saved automatically and keep
unchanged even power-off.
Note: The antenna(s) used for this transmitter must not be co-located or operating in conjunction with any other
Only those antenna(s) tested with the device or similar antenna(s) with equal or lesser gain may be used with
