The CipherLab 308 is a USB-to-RS232 interface converter. This type of device is used to connect a computer's USB port to a device that uses an RS232 serial port for communication. This is particularly useful for older devices or industrial equipment that rely on serial connections.
Step 1: Download the Driver
Download the official package (e.g., PL2303_Prolific_DriverInstaller_vx.x.x.exe).
Step 2: Run the Installer as Administrator
Step 3: Reboot (Important) The installer may not require a reboot, but perform one manually to finalize the system-level changes.
Step 4: Connect the CipherLab 308
Step 5: Verify the Installation
The CipherLab 308 USB-to-RS232 Interface Converter is a humble piece of kit, often hidden behind a desk or tangled in a mess of cables. But without its dedicated driver, the modern supply chain would grind to a halt. It serves as a reminder that in the digital age, hardware is nothing without the software that drives it.
CipherLab 308 USB-to-RS232 interface converter requires the Silicon Labs CP210x USB to UART Bridge VCP Driver cipherlab 308 usb-to-rs232 interface converter driver
to function. Once installed, your computer will recognize the device as a virtual COM port, allowing serial communication with barcode scanners or mobile computers. 🛠️ Installation Steps Download Driver: Visit the Silicon Labs VCP Driver page to download the " CP210x VCP Windows " driver kit.
Unzip & Run: Extract the folder and run CP210xVCPInstaller_x64.exe (for 64-bit Windows). Connect Hardware: Plug the CipherLab 308 into your USB port after installation is complete.
Verify COM Port: Open Device Manager and check under Ports (COM & LPT) to find the assigned port number (e.g., COM3). Key Specifications Chipset: Silicon Labs CP210x
Compatibility: Works with CipherLab 150x, 156x, 166x, 8xxx, and 25xx series. OS Support: Windows (XP to 11), Linux, and Mac OS.
Features: Provides power directly to scanners via USB; includes LED transmission indicators. Troubleshooting
Device Not Found: Ensure the "VCOM" mode is enabled on your scanner by scanning the appropriate configuration barcode.
Multiple Drivers: If the standard driver fails, check DriverIdentifier for specific OEM versions linked to your hardware.
Port Reset: If the port is not appearing, restart your computer to apply the Virtual COM settings.

The CipherLab 308 USB-to-RS232 Interface Converter is a specialized communication cable used to connect CipherLab barcode scanners and mobile computers (such as the 8000, 8200, 8400, and 8700 series) to a PC. It functions as a Virtual COM (VCOM) bridge, allowing the computer to communicate with serial devices via a USB port. Technical Overview
The "308" designation refers to the specific controller housed within the cable that translates RS232 serial signals to USB.
Chipset: The hardware typically utilizes a Silicon Labs CP210x USB-to-UART bridge.
Functionality: Unlike standard charging cables, the 308 cable is primarily for data transfer and may not support device charging.
Virtual COM Port: Once installed, the driver assigns a specific COM port number to the device, which can be viewed in the Windows Device Manager under "Ports (COM & LPT)". Driver Installation Guide
To ensure proper communication, the driver should ideally be installed before connecting the cable to the computer.
Download: Drivers are available on the CipherLab Download Center under "Utilities" or "Drivers".
Extraction: Unzip the downloaded file (often a .zip or .rar package).
Execution: Run the setup.exe or pre-installer file. Follow the on-screen prompts and click "Finish" when complete. If the device is not recognized at all:
Connection: Plug the 308 USB converter into an available USB port. Windows should recognize it as "CIPHERLAB 308 USB-to-RS-232 Interface Converter".
Configuration: Some scanners require a specific barcode to be scanned to switch the interface to VCOM mode. Troubleshooting Common Issues
Unknown Device Error: If the device is not recognized, uninstall any existing driver versions, restart, and reinstall the latest driver before plugging the device back in.
Conflict with OS: Older versions of the driver may cause system instability (e.g., Blue Screen of Death) on modern operating systems like Windows 10 or 11; ensure you are using the latest version from the official CipherLab support portal.
COM Port Identification: If your software cannot find the scanner, check Device Manager to confirm which COM port number (e.g., COM3, COM4) was assigned to the "Silicon Labs CP210x" bridge. If youg., Windows 11).
Provide the setup barcodes needed to put your scanner into VCOM mode.
