IC‑7300 Connection Checklist
Before running the program, verify the following items:
1. Install the USB drivers from the ICOM Japan website (recommended).
2. Connect the radio to the computer using the USB cable.
3. Open Windows Device Manager.
Verify the COM Port
In Device Manager expand: Ports (COM & LPT)
Look for:
Silicon Labs CP210x USB to UART Bridge (COMx)

The COM number may be different on your computer. Write this number down because the program must be configured to use the same COM port.
Verify the Audio Device
In Device Manager expand: Sound, Video and Game Controllers
Look for:
USB Audio CODEC

This confirms the radio audio interface is working.
Check Power Management (Important)
Windows sometimes turns off USB devices to save power.
Go to:
Device Manager → Ports → Properties → Power Management

Uncheck:
'Allow the computer to turn off this device to save power'
Verify COM Port Settings
Device Manager → Ports → Properties → Port Settings

Recommended settings:
Bits per second: 115200

Check for Conflicts
