UART-1 Rx Data mux input
the UART-1 Rx (IT9919 pin 66, GPIO27) is also used for data (GPS aviation or any digital information)
mux input, while UART-1 Tx for debug message output.
The communication parameters for UART-1 are 115200,n,8,1.
Besides, to enable UART-1 data mux, you should set properly in AVSenderUARTGUI.exe.
Click on the tab “SerialPortConfig”, and set the configurations as,
Port number :1
Type: RS232
Communication parameters:
Baudrate/Data bit/Parity/Stop/Flow control:115200/8/none/1/none
Default::115200/8/none/1/none,
But you may set them to any other values preferred.
Trans mode: Transparent
Then, click on “Set SerialPortConfig” button.
Note: If you have changed the communication parameters (Baudrate/Data bit/Parity/Stop/Flow control),
1. You should reboot HV-320 for the new setting to take effect after clicking the “Set SerialPortConfig”
Button
2. The debug message port UART-1 Tx’s communication parameters are also changed because it’s the same
UART-1.
