The solution arrived in a small, anonymous box: a . A black dongle, half the size of a lighter, with a blue LED and a cheap-looking plastic shell. Frank plugged the RS-232 end into the CipherLab’s cradle, then the USB end into the PC.
Modern laptops and workstations rarely include native RS232 serial ports. The CipherLab 308 interface converter
Once connected, the hardware should be recognized as "CIPHERLAB 308 USB-to-RS-232 Interface Converter" and "CP210x USB Composite Device". Common Issues: Unknown Device:
The driver version numbering reveals important compatibility information: cipherlab 308 usb-to-rs232 interface converter driver
Ultimate Guide to the CipherLab 308 USB-to-RS232 Interface Converter Driver
Windows should automatically detect the new hardware and assign a virtual COM port (e.g., COM3 or COM4). Verify in Device Manager: Open Control Panel -> System -> Device Manager . Expand the Ports (COM & LPT) section.
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 The solution arrived in a small, anonymous box: a
The relies on a chipset—most commonly the Silicon Labs CP210x —to simulate a serial port (COM port) over a USB connection. The driver software tells Windows how to communicate with this chipset, creating a "Virtual COM Port."
The is software that allows legacy serial hardware to connect to modern computers using a USB port. This driver creates a virtual COM port on your computer, enabling communication between your operating system and CipherLab barcode scanners or other RS232 serial devices.
It is crucial to download the correct driver version for your operating system (Windows XP, 7, 10, or 11). Modern laptops and workstations rarely include native RS232
The CipherLab 308 converter typically uses a chipset. Therefore, you need the Prolific PL-2303 driver , not a driver specifically named "CipherLab 308."
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.
Windows Update automatically installed a newer, incompatible Prolific driver.
If you are encountering specific installation errors or if the driver does not match your OS, please verify the (found under Properties -> Details -> Hardware Ids) to ensure the VID_10C4&PID_EA60 matches the driver you are installing.
