Setting of channel, interface, and data format 
Before using HR-1003, the user needs to make simple configuration based on its own needs to determine the channel, interface mode and data format.
The user can change or view the module's interface baud rate, channel and address code. Parameter setting or reading as per the testing software HRPRO.exe in the PC (in products box).And the configuration is as follows:
Channel configuration:
Note: the frequency points corresponding to each channel can be adjusted based on the user’s needs.
HR-1003 micro-power wireless module to use
1) USB driver installation and serial search
Open "Division huaray communications users plate" in HR-1003 folder, find the USB drive, double-click to install. Insert after installation of hardware, find the new hardware, press the computer prompts. After a successful installation, the Device Manager PC-port (COM & LPT) to find out a new generation COMX. (X, said an Arabic numeral) This serial port for the former serial port.

2) Indicator Description
Chang liang red light emission data, the data after the red lights went out.
Chang liang received the green light data, received the green light out after the completion.

3) Data Transfer
HR-1003 series of products provide transparent data transfer interface, allowing users a variety of applications and protocols, to achieve point to point, multipoint transparent transmission. If the customer in order to reduce the workload of the terminal CPU, and reduce the development cycle, we can increase addressable, data acquisition and remote control functions on the basis of the original function.
HR-1003 series to provide 150 bytes of internal memory, so each frame can be transmitted at least 150bytes, while HR-1003 uses FIFO (FIFO) data transmission to meet the user a one-time transfer of large data packets (infinite length) of the requirements.

The standard configuration:
1, HR-1003 wireless transmission module  
2, Spring antenna (about 4.5cm)
