Connect a PC to TH-D72

This should work similar on Windows. Make sure the radio's USB-UART bridge is detected by Windows and change the serial device in the terminal configuration.

How to connect TH-D72 in serial mode

• Make sure you have firmware v1.10 installed
• Connect TH-D72 via USB cable to your PC
• Turn TH-D72 on, make sure you are not in TNC mode
• Run lsusb, you should see Silicon Labs CP210x UART Bridge somewhere
• Check if you find /dev/ttyUSB0 or /dev/ttyUSB1, this should be your TH-D72
• Start putty or any other terminal tool which can do serial communication.
• Use this configuration:
  • Connection type: Serial
  • Serial line: /dev/ttyUSB0
  • Speed: 9600
  • Data bits: 8
  • Stop bits: 1
  • Parity: None
  • Flow control: None
• Start the session

That"s all, now you can send the commands described here. If you type in FO 1 and press Enter, you should see the VFO configuration of Band B like FO 1,0430000000,7,0,0,0,0,0,0,08,08,000,0,01600000,0.

Important
