The DIGI-LUMEN RJ12 Linking Cables are designed for growers who want precise control and synchronised dimming across multiple DIGI-LUMEN ballasts. These shielded data cables connect directly from ballast to controller, or daisy-chain between ballasts, enabling centralised management of light output, timing, and safety shutdowns when used with compatible digital controllers.
Made with low-interference shielding and high-durability plugs, these RJ12 cables ensure reliable signal transmission across your entire lighting setup. Whether you’re using a multi-light array or running ballasts in series, these cables are essential for any controlled environment using DIGI-LUMEN digital equipment.
Synchronise your lighting system with clean signal control, just plug in and link up.

Directions for Use

Connect to Controller
Insert one end of the RJ12 cable into the “IN” port on the ballast and the other into your lighting controller.
Link Multiple Ballasts
Use additional RJ12 cables to daisy-chain from the “OUT” port of one ballast to the “IN” port of the next.
Secure Cables
Avoid tight bends or tension on connectors. Use cable clips or ties to manage excess slack.
Test Signal
Power on your controller and verify response across all linked ballasts before initiating your light cycle.
