Win4IcomSuite Won’t Connect to My Radio via IP

Introduction

Experiencing difficulties connecting Win4IcomSuite to your Icom radio via IP can be challenging. This guide aims to provide a comprehensive troubleshooting approach to resolve such connectivity issues.

Common Causes and Solutions

1. Firmware Compatibility

Issue: Outdated radio firmware may lack necessary CI-V commands required for IP communication.

Solution:

• Update Firmware: Ensure your Icom radio has the latest firmware installed. Some CI-V commands were added in newer firmware versions, which are essential for proper communication.

2. Network Configuration

Issue: Incorrect network settings can prevent the software from establishing a connection.

Solution:

• IP Address Verification: Confirm that the IP address assigned to your radio is correctly entered in Win4IcomSuite.
• Port Forwarding: Ensure that the necessary ports (default: 50001 for control, 50002 for CAT, and 50003 for audio) are forwarded correctly in your router settings to the radio’s IP address.
• Firewall Settings: Check that your computer’s firewall allows Win4IcomSuite to access these ports.

3. Virtual Serial Port Configuration

Issue: Improper setup of virtual serial ports can hinder communication.

Solution:

• Use Compatible Software: It’s recommended to use com0com version 2.2.2.0 for creating virtual COM port pairs, as newer versions may not function correctly with Win4IcomSuite.
• Configuration Steps:
  • Install com0com version 2.2.2.0.
  • Create a virtual COM port pair (e.g., COM17 and COM18).
  • Assign one end of the pair to Win4IcomSuite and the other to your third-party application.

4. Radio Settings

Issue: Incorrect radio settings can prevent successful connections.

Solution:

• USB Serial Function: Navigate to your radio’s menu and set the USB Serial Function to CI-V. This setting is crucial for proper communication.
• CI-V Address: Ensure that the CI-V address in Win4IcomSuite matches the one set in your radio.

5. Conflicting Applications

Issue: Other applications may be using the same ports, causing conflicts.

Solution:

• Identify Conflicts: Use tools like netstat to check if other applications (e.g., remote desktop software like AnyDesk) are occupying the necessary ports.
• Reconfigure Ports: If conflicts are found, reconfigure either Win4IcomSuite or the conflicting application to use different ports.
