Ld-c101 Usb To Ci-v Driver Direct

A useful summary paper from the Ham Radio .ru and eHam.net communities:

If you need a specific scientific paper (e.g., for citation), consider searching IEEE Xplore or Google Scholar for:
"USB to CI-V interface latency measurement" or "FTDI vs Prolific performance in radio control" – though none directly mention LD-C101.

Final practical tip: If drivers fail, replace the LD-C101 with a genuine USB-63C (Icom) or RigExpert CI-V – many LD-C101 clones use counterfeit Prolific chips that no longer have drivers on Windows 11.

The is a USB to CI-V control cable primarily used to interface Icom amateur radio equipment with a computer for rig control and frequency management. This interface serves as a bridge, allowing software to send and receive commands via the Icom Communications Interface V (CI-V) protocol. Driver and Chipset Details The functionality of the depends on the specific internal chipset used in the cable: CH340 Chipset: Most standard versions of the

use the USB-Serial CH340 chipset. For these, you must install the CH340 USB-to-Serial driver to create a Virtual COM Port on your PC. Ld-c101 Usb To Ci-v Driver

FTDI Chipset: High-end variants may use an FTDI FT232RL chip, which often provides better stability across different operating systems like Windows, macOS, and Linux. Drivers for these are typically available on the FTDI Chip website.

Plug-and-Play: Once the appropriate driver is installed, the cable should be recognized as a standard serial port, requiring no additional firmware programming. Technical Specifications Interface: USB (Type A) to 3.5mm mono jack. Cable Length: Typically 1.5 meters (approx. 5 feet).

Functionality: Supports data transfer rates from 300 baud to 3 Mbaud and handles CI-V commands for frequency and mode control.

Software Compatibility: Fully compatible with major ham radio suites including Ham Radio Deluxe, N1MM, Logger32, FLRig, and Fldigi. Compatible Radios The A useful summary paper from the Ham Radio

Before diving into drivers, let’s clarify the hardware. The LD-C101 is a USB interface cable designed primarily for Icom transceivers that use the CI-V (Communication Interface-V) protocol. IC-706, IC-7000, IC-718, IC-7300, and many other Icom models rely on this standard. If you need a specific scientific paper (e

The adapter converts USB signals from your PC into TTL-level serial signals required by the CI-V bus. Inside the plastic case of the LD-C101, there is typically a bridge chip—most commonly from Silicon Labs (CP210x family) or Prolific (PL2303 family).

Why the driver matters: Your operating system (Windows, macOS, Linux) does not inherently understand how to talk to this chip. The driver acts as a translator, creating a virtual COM port (VCP) that software like HRD, DXLab, or WSJT-X can use.

If you have a working radio, send FE FE 5E E0 03 FD (read frequency) to COMx. The radio should respond. Use a tool like CI-V Commander or Hamlib:
