Standard configuration:
* One HR-1028 RF module
* A 9pin flat Connection Line.
* A whip antenna(about 10cm)
 
Optional accessories:
* RS-232 interface programming connection Line. (Users can set the module parameters through the RS-232 of the computer easily)
* USB interface programming connection Line. (Users can set the module parameters through the  USB of the computer easily)
* Data transmission testing equipment. (User can test the module when select mode or actually use easily).
* Optional antenna (Users can according to their actually remands, choose their own antennas to achieve the optimal communications effect.
 NOTE:
* To achieve the optimal communications effect, please use less ripple power module, the maximum current of power should be greater than 1.5 times of the maximum current of modules.
* Only choose one interface of TTL、RS-485、RS-232,
* Baud rate classified:
   Interface rate: users can change through HRPRO.exe PC
   Air rate: it should be explained when users order product.
* Generally the module in receiving state, if the IDLE pin continuously connect low level (>200millisecond). At the same time the module can’t receive or transmit any data. Only When the IDLE pin hangs or in the state of high level (VH<3.5V), 150 ms later, the module will be in receiving state again. (If don’t need sleep function, the IDLE pin will be hang).
