CipherLab 308 is a specialized USB-to-RS232 interface converter designed primarily to connect older CipherLab barcode scanners and mobile computers—such as the CPT-800x or 83xx series—to modern computers via a Virtual COM Port (VCP) TSD-Expert.ru Core Functionality

The converter acts as a bridge, translating USB signals into RS232 serial signals. This allows legacy hardware and applications that strictly require a COM port to function over a standard USB interface. Driver Specifications & Details The "308" converter is built around the Silicon Labs CP210x Device ID: Typically identified by the hardware ID USB\VID_10C4&PID_EA60 Operating System Support: Standard drivers are available for Windows (XP through Windows 10)

, and the underlying Silicon Labs architecture also supports Linux and Mac OS. Virtual COM Port:

Upon successful installation, the system assigns a specific COM port number (e.g., COM3) to the device, which can be verified in the Windows Device Manager under "Ports (COM & LPT)". Installation & Troubleshooting

Proper installation is critical for the device to be recognized correctly by your system. Pre-Installation: It is highly recommended to run the driver setup file physically connecting the USB converter to the computer. Recognition:

The driver is a small piece of software that tells your operating system three critical things:

Important Note: Most CipherLab 308 converters do not use a proprietary CipherLab chip. They typically rely on third-party chipsets, most notably the Prolific PL-2303 series or the Silicon Labs CP210x series. This means the "official" driver may actually be a universal Prolific driver.


If you're having trouble finding or installing the driver for your CipherLab 308 USB-to-RS232 interface converter, checking the official website, using generic drivers for common chips, or contacting technical support might provide a solution. Always ensure you're downloading drivers from trusted sources to avoid any potential security risks.

The CipherLab 308 USB-to-RS232 Interface Converter is a critical utility for connecting legacy serial-based hardware, such as barcode scanners and mobile computers, to modern PC systems via a USB port. This converter functions by translating USB signals into RS232 serial signals, creating a "Virtual COM Port" (VCOM) that software applications can use to communicate with connected devices as if they were plugged into a traditional serial port. Key Technical Specifications Interface Type: USB to RS232 (D-Sub 15M connector). Step 3: Reboot (Important) The installer may not
