Ld-c101 Usb To Ci-v Driver May 2026

Solution: The driver installed only partially. Right-click the device in Device Manager > Update Driver > Browse my computer > Let me pick > Select "USB Serial Port" (if listed). Otherwise, re-run the installer as Administrator.

After the LD-C101 USB to CI-V driver is installed, hardware configuration is necessary. The LD-C101 is not plug-and-play regarding radio settings.

Solution: You have a counterfeit Prolific chip. Uninstall the Prolific driver and force-install an older version (v3.3.2.107 from 2012). Or better, buy a genuine LD-C101 with CP2102. Ld-c101 Usb To Ci-v Driver

Solution: USB power issue. Try a different USB port (preferably directly on motherboard, not a hub). Also, check your LD-C101 cable for shorts.

If the installer fails, you can manually force the driver. Solution: The driver installed only partially

Short the TX (Transmit) and RX (Receive) pins on the CI-V connector (pins 3 and 4 of a 3.5mm plug). Use a serial terminal like PuTTY or Termite.

  • Baud rate support: CI-V uses 4800 or 19200 bps commonly; adapter supports standard serial baud rates (from low to 115200+ depending on chipset).
  • Flow control: Typically no hardware flow control (CI-V is simple single-wire bus). Drivers expose RTS/CTS/DTR lines if chipset supports them.
  • Data framing: 8 data bits, no parity, 1 stop bit (8N1) commonly used for CI-V.
  • Compatibility with radio control software: Works with Ham Radio Deluxe, N1MM+, fldigi, WSJT-X, Icom's own RS-BA1/CI-V control apps, and custom scripts that open a serial port to send CI-V commands.

    • If you're unable to find a driver or if the device doesn't seem to work properly after installation, consider reaching out to the manufacturer's support team or communities related to amateur radio or Linux/Windows/macOS for more specific advice. Baud rate support: CI-V uses 4800 or 19200
