PD-Connex CX107 - 3-pin DMX Terminator for Professional Lighting
The PD-Connex CX107 is an essential component for any professional DMX lighting installation, designed to ensure maximum signal reliability and stability. This terminator connects to the last device in a DMX lighting chain to eliminate noise and interference caused by signal reflection, a common problem with long cable runs or multiple connected devices. By ensuring proper line termination, the CX107 effectively prevents erratic device operation, such as flickering, random flashing, or lack of response, allowing lighting programming to run smoothly.
Built with a robust metal housing and high-quality components, this terminator is designed to withstand the demands of continuous use on tours, at live events, and in fixed installations. Inside, a precision 120-ohm resistor absorbs the DMX signal at the end of the circuit, matching the characteristic impedance of the DMX cable. This simple yet crucial device is the ultimate solution for maintaining data integrity throughout the system and ensuring that each luminaire responds accurately and consistently to the controller's commands.
Main Features
-
DMX512 Signal Termination: Incorporates a 120 ohm resistor, the standard value for the DMX512 protocol, ensuring optimal signal absorption and preventing data bounce.
-
3-Pin XLR Connector: Equipped with a 3-pin male XLR connector, it offers universal compatibility with the vast majority of professional lighting equipment on the market, such as moving heads, LED PAR lights, smoke machines, and controllers.
-
Durable Metal Construction: Its metal body provides great strength and durability, ideal for professional environments where equipment is subjected to intensive use.
-
Compact and Simple Design: Its "plug-and-play" format allows for instant installation. Simply connect it to the DMX OUT port of the last device in the line to complete the circuit correctly.

Frequently Asked Questions
- Is it really necessary to use a DMX terminator?
- Yes, it is highly recommended and considered standard professional practice. While it may not be noticeable in very short chains with few fixtures, in most installations it is crucial to prevent signal reflection, which causes flickering and erratic behavior in the lights.
- Which device in the chain should I connect the terminator to?
- The terminator must always be connected to the DMX output port (DMX OUT or THRU) of the last physical device in the signal chain.
- What happens if I don't use a terminator in my system?
- Without a terminator, the DMX signal can "bounce" back at the end of the cable, traveling along the line again and corrupting the data. This commonly manifests as lights that flicker, move on their own, or don't respond to console commands.
- Is this terminator compatible with any brand of DMX equipment?
- Yes, by complying with the DMX512 standard and using a 3-pin XLR connector, it is compatible with all equipment that follows this protocol, regardless of the brand.
