Ld-c101 Usb To Ci-v Driver Instant

Assume you have a CP2102-based LD-C101. Here is the definitive process:

For macOS users: The driver is often built-in (Apple provides a generic CDC driver). If not, install "SiLabsUSBDriverDisk.dmg" from Silicon Labs.

For Linux users: The CP210x driver is native in the kernel. Run dmesg | grep cp210x to confirm.

A: Yes, with the correct Silicon Labs CP210x driver (v11.2.0 or later). Prolific-based units may fail.

Once the driver is active, do not assume it works. Test thoroughly.

The LD-C101 USB to CI-V cable is a specialized interface designed to bridge Icom amateur radios with modern computers for CAT (Computer Aided Transceiver) control. While Icom's latest rigs often feature direct USB ports, the LD-C101 is an essential tool for older models, allowing you to manage frequency, mode, and memory settings through software like Ham Radio Deluxe or WSJT-X. Essential Features of the LD-C101

The LD-C101 functions as a digital bridge, converting your computer's USB signals into the CI-V (CIV) protocol used by Icom. Ld-c101 Usb To Ci-v Driver

Plug-and-Play Design: Typically features a standard USB-A connector on one end and a 3.5mm mono jack for the radio's CI-V port.

Virtual COM Port (VCP): The cable uses an internal chipset—often from FTDI or Silicon Labs—to appear as a standard COM port on your PC.

CAT Control Support: Enables remote operation, frequency logging, and automated satellite tracking.

Power Efficient: Powered directly via the USB bus, eliminating the need for external power supplies. Driver Installation Guide

To use the LD-C101, you must install the correct Virtual COM Port (VCP) driver before connecting the cable to your PC. Icom ic-718 setup with CI-V cable on Windows 7? - Facebook

The LD-C101 USB to CI-V cable is a critical interface tool for amateur radio enthusiasts who want to bridge the gap between their legacy or modern Icom transceivers and personal computers. By using this cable, operators can automate frequency control, manage logging, and run advanced digital modes through a single 3.5mm "Remote" jack. The Role of the LD-C101 Driver

Because the LD-C101 is essentially a USB-to-Serial converter, your operating system must recognize the specific hardware chip inside the cable to create a virtual COM port. Assume you have a CP2102-based LD-C101

Chipset Identification: The LD-C101 typically utilizes the CH340 chipset. This is a common and reliable serial-to-USB bridge used in many ham radio accessories.

Virtual COM Port: Once the driver is installed, Windows, macOS, or Linux will assign a port (e.g., COM3 or COM6) to the cable. This port is what your software—like Ham Radio Deluxe, N1MM, or FLRig—uses to "talk" to your radio. Where to Download the LD-C101 Driver

Since the cable relies on the CH340 chipset, you can obtain the latest drivers from several official sources:

Chelegance Support: As the primary manufacturer of the LD-C101 cable, Chelegance provides direct links to compatible drivers for Windows 10 and 11.

WCH Official Site: For the most up-to-date CH340 drivers, users often go directly to the manufacturer, WCH (Jiangsu Qinheng Microelectronics).

Icom Support: While Icom radios often use Silicon Labs drivers for their built-in USB ports, external CI-V cables like the LD-C101 often differ. If you are using an Icom-branded cable (like the CT-17), you should visit the Icom Japan Firmware/Driver page. Installation Guide: Step-by-Step

The LD-C101 USB to CI-V driver is a software component that enables communication between a computer and certain devices, such as amateur radio transceivers, that use the CI-V (Controller Interface V) protocol. This protocol is commonly used in amateur radio equipment to allow for remote control and data transfer. For macOS users: The driver is often built-in

The LD-C101 is a specific USB interface cable designed for this purpose, and its driver software allows the computer to recognize and interact with the device.

Here are some key points about the LD-C101 USB to CI-V driver:

If you're looking for more information or need to download the driver, I recommend checking the manufacturer's website or searching for the specific driver version compatible with your operating system.


In the world of amateur radio, computer control of transceivers has moved from a luxury to a necessity. Whether you are logging contacts digitally, operating FT8, or simply adjusting frequency from a PC, a reliable interface between your computer and your radio is critical.

One of the most popular and cost-effective solutions on the market is the LD-C101 USB to CI-V adapter. However, like any USB-to-serial device, its functionality hinges on one crucial software component: the LD-C101 USB to CI-V driver.

If you have recently purchased this adapter or are struggling with "Device not recognized" errors, you are in the right place. This long-form guide will walk you through everything you need to know about the driver, from installation to advanced debugging.

If you use FT8, RTTY, or PSK31, the LD-C101 USB to CI-V driver alone isn't enough. You also need audio isolation. However, for CAT control, a properly installed driver ensures low latency.

Tips for low latency:
