HX-DU1021D Radio Modem Configuration Operation Instructions
一、
Instructions for setting up the test environment
1、 Connect the two radio modems to the computer using a USB-to-RS232 cable
2、Open two serial port assistants (one for sending and one for receiving).
The serial port configuration for the radio modem is as follows:
Baud rate: 115200
Data bits: 8
Parity: None
Stop bits: 1
3、 Turn on the power switch of the radio to enter the startup mode. At this time, connect the radio through
a serial port and send a command to enter the boot mode. If the serial port assistant is configured
correctly, it will display "into boot".
4、Turn the configuration switch on the test board to the GND end, and the radio outputs 'configuration
mode'. Use the command to set the transmitting and receiving frequency point, air baud rate, working
mode and other parameters.
5、Turn the configuration switch on the test board to the VCC end, and the radio will output "transparent mode".
when sending data to the transmitting radio through the serial port, the serial port assistant connected to the
receiving radio will display the same data.
