Product Information
Full details
This Kenable 4-core screened twisted pair DMX cable is designed for professional lighting control applications, offering high-quality signal transmission with its tinned copper conductors and braid. While it provides reliable performance, its 500m length may be more than needed for smaller setups, and its blue color might not suit all aesthetic requirements.

FAQs
What does '4 core' mean for this cable?
It means the cable contains four individual insulated conductors, plus shielding. For DMX, this typically includes two conductors for data transmission (data+ and data-), one for a signal common/drain, and sometimes a fourth for additional shielding or a second data pair if needed.
Is this cable suitable for analogue audio signals?
While it has good shielding, this cable is specifically designed and optimized for digital DMX signals. For analogue audio, dedicated balanced audio cables are generally recommended for best performance.
How should I terminate the 4 cores for DMX512?
Typically, pin 1 of the XLR connector is connected to the cable's drain wire and/or braid shield. Pin 2 is connected to one of the data conductors (e.g., data-), and Pin 3 is connected to the other data conductor (e.g., data+). The fourth core's usage depends on the specific DMX application or standard being followed, but often it's tied to the shield or drain.
What is the diameter of the cable?
The cable has an outer diameter of 5.8mm.
Can I cut this cable to a shorter length?
Yes, you can cut the cable to any desired length. Ensure you use appropriate tools and techniques to properly strip and re-terminate the cable ends with suitable DMX connectors.
What is the weight of the cable per meter?
The product dimensions indicate a 500m lead weighs 34kg, which is approximately 0.068 kg per meter.
Does the screening offer significant protection against interference?
Yes, the high-density tinned copper braid provides substantial protection against electromagnetic interference (EMI) and radio frequency interference (RFI), which is crucial for maintaining clean DMX signals.
Troubleshooting
No signal to lighting fixtures
Check that all DMX connectors are securely attached and wired correctly (pin 1 to shield/drain, pin 2 to data-, pin 3 to data+). Verify that the cable is plugged into the correct DMX ports on the controller and fixtures.
Flickering or intermittent lighting effects
Inspect the cable for any physical damage, such as cuts or crushed sections. Ensure the cable run is not too long for the DMX protocol being used without a signal booster, and check for sources of strong electromagnetic interference near the cable run.
Poor signal quality over long distances
Confirm that the cable's braid and drain wire are properly terminated to provide effective shielding. For very long runs (beyond 100m), consider using a DMX repeater or line driver to boost the signal strength.
Pros and Cons
Pros
- Excellent signal integrity due to tinned copper and braid screening.
- Reliable performance in demanding environments.
- Durable construction suitable for professional installations.
- Suitable for extensive lighting setups with its 500m length.
- Easy to identify and manage with its distinct blue color.
Cons
- The 500m length might be excessive and costly for smaller applications.
- The blue color may not integrate visually with all stage or studio designs.
- Requires specific connectors for termination.
- Potentially heavier and less flexible than thinner gauge cables.
Setup, Compatibility & Care
Setup: This cable is designed to be terminated with appropriate DMX connectors (typically XLR 3-pin or 5-pin). Ensure proper stripping of the outer jacket and braid, followed by secure connection of the 4 cores (typically data+, data-, drain, and shield) to the connector pins according to DMX standards.
Compatibility: Compatible with all standard DMX512 lighting equipment and controllers. It is designed for digital lighting control protocols.
Care: Store the cable neatly coiled to prevent kinks and damage to the internal conductors. Keep away from extreme heat, moisture, and sharp objects. Periodically inspect the cable and connectors for any signs of wear or damage before and after use to ensure optimal performance and safety.
