RJ12 Extension Cable Set

Extend Module Connections Across Larger Grow Spaces

Every TrolMaster module and sensor ships with a 16 ft RJ12 cable, a Y-splitter, and a 4 ft cable to reach the Hydro-X controller, which covers most single-room layouts without any extra cabling. When modules sit farther apart than that included run allows, the ECS-1 extension cable set adds another matched 16 ft cable, Y-splitter, and 4 ft cable to close the gap.

It's built to the same specification as the cabling that ships in the box with every module, so there's no mismatch in connector type or cable rating when the two are joined.

Key Features & Benefits

• 16 Ft Male-to-Male RJ12 Cable — extends the primary connection run between a module and the controller.
• 4 Ft Male-to-Male RJ12 Cable — provides a shorter secondary connection for tighter spacing.
• RJ12 T-Splitter Included — supports branching the run to an additional module.
• Matches Standard TrolMaster Wiring — stays fully compatible with the cabling included with every module.

Who Should Use the ECS-1 Extension Cable Set

TrolMaster users connecting modules that sit farther apart than the standard included cabling allows, such as in a long greenhouse bay or a multi-room build, are the intended buyer for the ECS-1. It's the simplest fix before considering the bulk ECS-500 cable roll.

About TrolMaster

TrolMaster standardizes on RJ12 connectors across its Hydro-X device-station lineup, a choice the Sacramento, California company makes so that accessories like the ECS-1 stay interchangeable across the entire product line instead of being tied to one specific module type. That standardization is part of why the company's device stations are described as plug-and-play.

Frequently Asked Questions

What does this set include?

A 16 ft cable, a 4 ft cable, and a T-splitter. All three match the connector type used throughout the Hydro-X lineup.

What is it used for?

Extending the distance between TrolMaster modules and the Hydro-X controller. It's a straightforward fix when the included cabling falls short.

What connector type does it use?

RJ12. That is the same connector used on every standard TrolMaster module and sensor cable.

Is it compatible with standard TrolMaster cabling?

Yes, it matches the cables included with TrolMaster modules and sensors exactly. No adapter or converter is needed to join them.

How do I install the ECS-1 into an existing setup?

It plugs inline between a module's own cable and the Hydro-X controller using the included T-splitter. No cutting or splicing of existing wiring is required.
