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.
