Ld-c101 Usb To Ci-v Driver =link= Jun 2026

Plug the USB end of the LD-C101 into an available port on your computer. To verify the installation:

The LD-C101 is a 1.5-meter cable featuring a USB-A plug on one end and a 3.5mm mono CI-V plug on the other. Because it uses the , the driver's primary job is to create a virtual COM port on your operating system. This allows the computer to treat the radio as a legacy serial device, ensuring compatibility with popular software like Ham Radio Deluxe, N1MM Logger+, and FLRig.

This can be caused by USB power management settings.

The LD-C101 acts as a bridge between your PC's USB port and the 3.5mm CI-V remote jack on your radio. CI-V Cable - IC706 - Groups.io

Before downloading a driver, you must identify the hardware chip inside your LD-C101 cable. Manufacturers usually build these cables around one of three major USB-to-serial chipsets: Ld-c101 Usb To Ci-v Driver

: It is frequently used with older but popular Icom models like the IC-756 Pro Software Integration

Kenji took a sip of vending-machine coffee, bitter as regret. He hooked the Ld-c101 to his logic analyzer. The USB endpoint descriptors checked out—vendor ID 0x1A86, a generic Chinese USB-to-serial chip. But the real logic was in the onboard PIC microcontroller, which translated USB bulk transfers to CI-V’s weird electrical levels.

: Modern drivers often auto-install on newer versions of Windows 10 and 11, though manual installation is a reliable backup.

: You can control your radio from across the room—or across the world—via the computer interface. Plug the USB end of the LD-C101 into

Connecting your Icom amateur radio to a computer opens up a world of automated logging, digital modes, and software-defined control. One of the most reliable tools for this connection is the LD-C101 USB to CI-V interface cable.

The internal electronics of the LD-C101 are surprisingly simple. It uses a USB-to-serial bridge chip to convert the USB signals from your computer into the TTL-level serial signals required by the Icom CI-V protocol. The CI-V bus uses a single conductor for data transmission and operates at TTL voltage levels (typically 5V) rather than the higher voltages of a standard RS-232 serial port.

A hardware cable is only as good as the software driving it. The LD-C101 relies on an internal bridge chip (typically manufactured by Prolific or FTDI) embedded inside the USB connector housing. Installing the exact matching driver ensures: This allows the computer to treat the radio

: Obtain the CH340 driver from a trusted manufacturer site like Chelegance or directly from the WCH official website.

The core of this device usually relies on a or CH340/CH341 chipset, which requires a specific driver to be recognized by the operating system. Downloading the LD-C101 USB to CI-V Driver

Ensure the 3.5mm plug is fully inserted into the "REMOTE" jack, not the speaker or key jacks.

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 or Prolific (PL2303 family) .
