Usb-to-rs232 Interface Converter Driver [verified] - Cipherlab 308

The converter cable acts as an active data translator, routing signals through a physical on the CipherLab device cradle to a standard USB Type-A connector plugged into the host computer.

He spent two hours in the IT rabbit hole. Registry edits. Compatibility mode. A bootleg driver from a German hobbyist forum last updated in 2015.

: The device utilizes a high-quality Silicon Labs (CP210x) chipset. This is a significant advantage over cheaper "Prolific" clones, which often suffer from driver issues or "Code 10" errors on newer versions of Windows.

I’m unable to provide a full driver download or a complete driver article, but here is the technical information you need for the . cipherlab 308 usb-to-rs232 interface converter driver

The is the vital software required to establish communication between legacy CipherLab barcode scanners, mobile data terminals, and modern PC hardware . Because modern computers lack native DB9 serial ports, the CipherLab 308 hardware relies on a built-in Silicon Labs CP210x USB-to-UART bridge controller chip to map traditional serial signals over a standard USB interface. Hardware Architecture and Specifications

CipherLab no longer distributes the driver directly for these newer systems. Instead, you must download the directly from Silicon Labs. The latest version as of this writing is v11.5.0 , released December 31, 2025.

Complete Guide to CipherLab 308 USB-to-RS232 Interface Converter Driver: Installation and Troubleshooting The converter cable acts as an active data

The is a vital software component designed to bridge the technological gap between legacy serial communication and modern USB-equipped hardware. In enterprise environments—such as warehousing, retail logistics, and manufacturing—legacy barcode scanners, data terminals, and programming cradles often rely on the RS-232 serial interface.

When the 308 device is connected to a computer for the first time, the system recognizes it as two distinct hardware components: “CIPHERLAB 308 USB-to-RS-232 Interface Converter” and “CP210x USB Composite Device”. This dual recognition occurs because the 308 uses a Silicon Labs CP210x series chipset to perform the USB-to-serial conversion. The CP210x chip requires a Virtual COM Port (VCP) driver to create a software-based serial port (e.g., COM3, COM4) that allows the operating system to communicate with the attached scanner as if it were connected via a traditional RS232 port.

If the device shows an error in Device Manager, uninstall it and download the latest Silicon Labs driver. Compatibility mode

Some users have reported that the 308 scanner works on the local machine but fails in a Remote Desktop or terminal server session (e.g., Microsoft Terminal Services). This issue may be specific to certain scanner models—some users have observed that CipherLab 8300 Series terminals work in terminal sessions while CipherLab 1000 scanners do not. Workarounds may include:

Technically, the 308 cable is built around the . Therefore, the "CipherLab 308 driver" is essentially the CP210x USB-to-UART Bridge driver . The hardware ID USB\VID_10C4&PID_EA60 identifies it as a Silicon Labs serial device. Installing this driver is what enables the virtual COM port, known in Linux as /dev/ttyUSB0 or /dev/serial/by-id/... .

The converter utilizes a chipset. To use the device, you must install the Silicon Labs VCOM (Virtual COM Port) driver.

Visit the CipherLab Support Website and search for the 308 converter driver or CP210x Virtual COM Port Drivers.

The 308 converter is often used with tools like to configure the scanner. Ensure that this software is configured to use the same COM port number found in the Device Manager.
