The Digilent USB Jtag Cable connects a Windows PC to compatible development hardware for JTAG programming and debugging. Its driver lets supported development tools communicate with the cable over USB, helping you access your target board. For Windows 11, 10, 8, or 7, choose a driver package that explicitly supports your operating system and cable model.

Key Features

• USB device recognition: Helps Windows identify the cable and make it available to compatible programming software.
• JTAG communication support: Provides the connection needed for supported tools to configure or program compatible target devices.
• Development tool integration: Enables applications that support Digilent cables to access connected hardware for supported programming and debugging tasks.
• Windows compatibility: Supports setup on the listed Windows versions when you use the appropriate driver release and system architecture.

How to Install

1. Check compatibility before downloading. Confirm your cable model, Windows version, and whether your system requires a 32-bit or 64-bit package. Review any requirements for the development software you plan to use.
2. Download and prepare the driver. Obtain a trusted Digilent-compatible driver package, extract it if necessary, and read any included installation instructions. Some development suites include cable drivers with their installer.
3. Run the installation. Close programming applications and launch the installer with administrator permissions if required. Follow its prompts, including any instructions about when to connect the USB cable.
4. Connect and verify the hardware. Attach the Digilent USB Jtag Cable to an available USB port. Open Device Manager and check that the cable is detected without a warning icon. Restart Windows if the installer requests it.
5. Test the connection in your development tool. Connect the cable to a compatible, correctly powered target board, checking connector orientation against the hardware documentation. Open your programming software, select the cable, and scan for the target device.

If Windows detects the cable but your software cannot find the target, check board power, JTAG wiring, and tool compatibility before reinstalling the driver. Although this device may appear in a printer download category, it is a JTAG programming interface—not a printer—and does not use a standard printer driver.

Common Issues and Fixes

• Installer fails or rolls back: Install the Digilent Adept Runtime/driver package as Administrator before connecting the JTAG cable. Temporarily disable antivirus if it blocks the signed driver, reboot, then plug in.
• Cable not detected: Use a direct USB port, not a hub; try another cable/port. Check Device Manager for “Digilent USB Device” or an unknown device. Uninstall the faulty entry, unplug, reinstall Adept, and reconnect.
• Version conflicts with Vivado/ISE: Multiple Adept or cable-driver versions can conflict. Remove old Adept versions, keep one current runtime, update Vivado/ISE cable drivers or `hw_server`, and reboot before testing.
