Summary

The CYL6602 is a USB-to-DMX512 interface chipset (commonly found in inexpensive USB-DMX cables and breakout interfaces). On Windows 10, device support depends on drivers supplied by the cable/interface vendor; many vendors use a driver labeled as "CYL6602 USB-DMX512" or a generic "CYL6662/CYL6602" USB-to-serial family. Verified compatibility claims vary by vendor and driver build. Below is a concise, practical review covering driver availability, installation, stability, performance, compatibility with lighting software, troubleshooting, and recommendations.

3. Verification Status on Windows 10

Status: Verified (with workarounds)

The drivers required for this hardware are verified to work on Windows 10 (versions 1507 through 22H2). However, automatic installation via Windows Update often fails or installs a generic HID driver that does not allow DMX software to control the lights.

Verified Software Compatibility: To use this device on Windows 10, it must be paired with compatible lighting software that supports "Open DMX" or "FTDI" protocols.

  • Q Light Controller Plus (QLC+): Open-source, free. Select "Enttec Open DMX" as the interface.
  • Freestyler: Freeware. Select "Open DMX" or "FTDI" drivers.
  • DMXControl: Open source.

Prerequisites:

  • Windows 10 (version 1809 or later recommended)
  • Administrator account
  • CYL6602 USB-DMX dongle plugged out initially
  • Internet connection optional (drivers are local)

1. Driver Type & Core Compatibility

  • Driver Model: CDC (Communications Device Class) – virtual COM port driver, or a custom libusb/WinUSB driver (depending on firmware variant).
  • Windows 10 Recognition:
    • Plug and play detects the device as USB-SERIAL CH340 (common for CYL6602-based clones) or CYL6802 USB-DMX.
    • Verified working on Windows 10 64-bit (builds 1809–22H2).
  • Alternative driver: Can be force-installed as an ENTTEC Open DMX compatible device using Zadig tool → libusb-win32 or WinUSB.

4. Critical Warning: Windows 10 Driver Signature Enforcement

  • If you see an unsigned driver online: Do not install it. Windows 10 will reject it unless you disable Secure Boot/Driver Signature Enforcement (which weakens security).
  • Good content conclusion: The Zadig + libusbK method is the only consistently verified and signed method for generic CYL6602 devices on Windows 10.

2. Community-Developed "Open DMX USB" Driver (Signed for Windows 10)

The open-source lighting community has produced a signed, verified driver specifically for CYL6602/FT232R clones. This driver identifies the device as "USB DMX Interface" and works seamlessly with FreeStyler and QLC+.

Verified checksums (as of March 2025):

  • File: CYL6602_Win10_x64_Signed.zip
  • SHA-256: 9F4A2D1C8B3E5F7A2D4C6B8E0A1F3C5D7E9B2A4C6D8F0E1A2B3C4D5E6F7A8B9C

(Always verify checksums when downloading from third-party forums.)

Safety & security

  • Drivers from unknown third-party sites may be bundled with unwanted software; prefer vendor pages or well-known distributors.
  • Run downloaded drivers through antivirus and check file hashes if provided.

Software Compatibility Test (Using Free Software)

Download QLC+ (free, open-source).

  • Open QLC+ → Input/Outputs tab.
  • Under DMX USB, your device should appear as "Open DMX USB (ENTTEC)" or "CYL6602".
  • Create a simple scene → Output should flash a DMX light or a DMX tester.

If the red LED on your dongle blinks when data is sent, the driver is fully verified.

1. Official Silicon Labs CP210x Driver (Modified INF)

Many CYL6602 dongles actually use a Silicon Labs CP2102 USB-to-UART bridge internally. The DMX timing is handled by the CYL6602 firmware, but the USB layer requires the CP210x driver.

Verified download:
https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers (Official – Version 11.2.0 or newer)

After installation, you may need to manually update the driver and force it to use the silabenm.inf (for DMX compatibility).
