The Cipherlab 308 is a type of interface converter that allows you to connect a device with an RS232 (serial) port to a computer via a USB port. This is particularly useful for devices that only have serial connections for communication, such as some barcode scanners, printers, and other industrial equipment.
Without the correct driver, your computer will see the converter as an “Unknown USB Device” or fail to assign a COM port number. The driver acts as a translator, instructing Windows, Linux, or macOS how to package the incoming scanner data into a virtual serial port. The top driver for this device is the one that ensures zero data loss, low latency, and compatibility with the latest operating systems.

The CipherLab 308 USB-to-RS232 interface converter is a critical bridge for legacy hardware. This adapter allows modern computers without serial ports to communicate with RS232-based devices like barcode scanners and scales. Getting the driver setup right is the most important step for a stable connection. Understanding the CipherLab 308 Converter
The CipherLab 308 is designed for industrial and retail environments. It converts a standard USB signal into a serial RS232 signal. This is essential for connecting older CipherLab mobile computers or scanners to newer laptops and desktops. Bus Powered: No external power supply needed. Plug-and-Play: Recognized as a Virtual COM Port (VCP). Compatibility: Works with most Windows and Linux systems.

Finding the correct driver ensures that your system assigns a COM port to the device. Using the wrong version can lead to "Device Not Recognized" errors. 1. Official CipherLab Support Portal Always start at the official manufacturer website. Navigate to the Downloads or Support section. Search for "308 Interface Converter" or "USB to RS232."
Download the package specifically for your OS (Windows 10, 11, or Legacy). 2. Prolific or FTDI Chipset Drivers The CipherLab 308 often utilizes third-party chipsets. Check the device hardware ID in Device Manager.
If it uses a Prolific PL2303 or FTDI chip, you can download drivers directly from those manufacturers for the most up-to-date performance. Installation Guide: Step-by-Step
Follow these steps to ensure a clean installation of the 308 driver.
Disconnect the Device: Do not plug in the 308 converter until the software is installed.
Run as Administrator: Right-click the driver setup file and select "Run as Administrator."
Complete the Wizard: Follow the prompts and restart your computer if requested. Connect the Hardware: Plug the USB end into your PC. Verify in Device Manager: Open "Device Manager." Look under "Ports (COM & LPT)."
Ensure "USB-to-Serial-Comm Port" appears without a yellow exclamation mark. Troubleshooting Common Issues Title: Solved: CipherLab 308 USB to RS232 driver
If the driver is installed but the device isn't communicating, check these settings: Incorrect COM Port Assignment
Software often defaults to COM1 or COM2. If the driver assigns your 308 to COM8, you must change the settings in your application to match. Baud Rate Mismatch
The 308 converter must match the baud rate of the serial device it is connected to.
Common settings: 9600 baud, 8 data bits, no parity, 1 stop bit. Driver Signature Enforcement
On Windows 10 and 11, unsigned drivers may be blocked. Ensure you are using the "Certified" version of the CipherLab 308 driver to avoid security blocks.
💡 Pro Tip: Always check your cable connections. A loose RS232 thumb screw is the most common cause of intermittent data loss.
CipherLab 308 USB-to-RS-232 Interface Converter driver is based on the Silicon Labs CP210x chipset. This converter allows older CipherLab barcode scanners
and mobile computers to communicate with modern PCs by creating a virtual COM port. Download and Driver Information The driver files are typically named The CipherLab 308 uses a Prolific PL-2303 chip
Here’s a step-by-step guide to installing and using the CipherLab 308 USB-to-RS232 Interface Converter driver (often used with CipherLab barcode scanners).
Virtually all modern computers lack native RS232 ports. A simple USB-to-RS232 cable is not enough—the CipherLab cradle requires a specific level of voltage and signal timing. The official CipherLab 308 USB-to-RS232 Interface Converter (often bundled under part number CBL-308-USB-01) is a dongle that converts the cradle’s serial signal into a USB protocol.
Driver Update Tools: You can also use third-party driver update tools, but be cautious and only use reputable ones to avoid malware.
Serial Port Driver: Most USB-to-RS232 converters use a chip from companies like FTDI, Prolific, or Silabs, and the driver might be generic. For example, if it uses an FTDI chip, you can download the driver from FTDI's website.
Over the years, several driver versions have been released. Based on user feedback, stability tests, and CipherLab’s official support lifecycle, the top driver is widely considered to be:
If you cannot make the Prolific-based converter work, consider these top alternatives:
However, for industrial environments where reliability is paramount, the official CipherLab 308 USB-to-RS232 Interface Converter paired with the top Prolific driver remains the gold standard.
