Why Choose the Gavita E-Series LED Adapter 3-Way Splitter

This adapter addresses a specific integration challenge: Gavita 1700e LED fixtures do not communicate directly with EL series controllers out of the box. The 3-Way Splitter bridges that gap by placing an inline adapter on the fixture power cord and converting the fixture’s output to the RJ45 control signal format the EL series expects.

• Inline installation, no rewiring: The adapter connects between the fixture power cord and the outlet. No hardwiring or modification to the fixture is required, keeping installation straightforward and reversible.
• Daisy chain support: RJ45 connectors on the adapter allow multiple units to be linked in sequence, so an entire row or zone of 1700e fixtures can be managed from a single EL series controller without running individual cables back to the controller for each fixture.
• 3-way split for flexible layouts: The three-port design means a single adapter can branch the control signal to more than one downstream device, reducing the total number of cables and adapters needed in multi-light configurations.
• Commercial certifications: The cETLus listing confirms the adapter meets North American electrical safety standards. The IP66 rating means it is dust-tight and protected against high-pressure water jets, making it appropriate for the humidity conditions common in commercial production spaces.
• Compatible with multiple controller cables: Communication with the EL series controller is achieved via Gavita cables 906715, 906716, or 906717, giving growers a choice of cable lengths and configurations for their specific layout.

Best Uses for the Gavita E-Series LED Adapter 3-Way Splitter

This adapter is purpose-built for a narrow but important use case: connecting Gavita 1700e LED fixtures to an EL series controller network. The following scenarios represent where it fits best.

• Commercial grows using Gavita 1700e fixtures with EL controllers: Facilities that have already invested in Gavita EL series controllers but are adding or replacing fixtures with 1700e LED units need this adapter to maintain centralized light control. It restores the same controller-driven dimming and scheduling that operators depend on for consistency across the canopy.
• Rows of fixtures requiring daisy-chain wiring: When fixtures are laid out in long rows, daisy chaining through RJ45 connectors simplifies cable runs significantly. Rather than running a separate control wire from each fixture back to the controller, the signal can pass from adapter to adapter down the row.
• Upgrading from HPS to LED while keeping existing controllers: Growers transitioning from high-pressure sodium fixtures to Gavita 1700e LEDs can retain their EL series controllers with this adapter, lowering the total cost of the LED upgrade. If you are also considering the Gavita Pro 1700e LED fixture, this adapter is the component that connects it to your existing control infrastructure.
• Multi-zone lighting installations: In facilities with separate veg and flower zones, each zone’s fixtures can be grouped on their own controller circuit using adapters in a daisy chain, enabling independent dimming schedules per zone without additional hardware.
• Temporary or modular facility setups: Because installation is inline and non-permanent, the adapters can be moved and reconfigured as the facility layout changes, without leaving behind modified fixtures or wiring.

Compatibility

The Gavita E-Series LED Adapter 3-Way Splitter (RJ45) is designed specifically for the Gavita E-Series ecosystem. Before purchasing, confirm the following compatibility requirements are met.

• Fixture: Gavita 1700e LED. The adapter is described as designed to be used with the 1700e specifically. Compatibility with other Gavita LED models is not confirmed in the canonical product data.
• Controller: Gavita EL Series controllers. The adapter enables EL series control of the 1700e fixture. The EL controller communicates with the adapter via RJ45-connected cables.
• Communication cables: Gavita part numbers 906715, 906716, or 906717 are the supported cables for connecting this adapter to the EL controller. These are sold separately. Growers will need at least one of these cables per controller-to-adapter connection.
• IP66 environment suitability: The IP66 rating covers dust ingress (fully dust-tight) and water ingress protection against high-pressure jets. This makes the adapter suitable for the elevated humidity and occasional water exposure conditions in commercial indoor grow environments.
• Safety listing: cETLus listed for North American use (US and Canada). Confirms the adapter meets applicable electrical safety standards for use in commercial installations.

This adapter is not a general-purpose RJ45 splitter. It is an E-Series specific component. Using it outside the Gavita E-Series / EL controller ecosystem is not supported by the product documentation.

For a complete lighting setup, you may also want to explore supplemental T5 fixtures for propagation areas or veg stages where the 1700e is not deployed.

Usage Guidelines

The adapter is a passive inline signal router, not an active controller. It does not generate, modify, or store control signals — it simply passes the RJ45 control signal from one connection point to the next while also splitting it to a third port in the 3-way configuration. The following guidelines apply to its use.

• Install one adapter per fixture: Each Gavita 1700e LED fixture requires its own adapter. The adapter sits between the fixture’s power cord and the outlet or power strip, so it is always associated with a single fixture.
• Connect RJ45 cables for daisy chaining: Use one RJ45 port to connect upstream to the EL controller (via a 906715, 906716, or 906717 cable) and the remaining ports to connect downstream to the next adapter in the chain or to leave open if this is the last adapter in the run.
• Keep daisy chain runs within controller limits: The EL series controller will have a maximum number of fixtures or adapters it can manage in a single daisy chain. Refer to the EL controller documentation for the per-controller fixture limit before planning your chain layout.
• Avoid exposure beyond IP66 rating: IP66 covers dust-tight and high-pressure water jet resistance, but not submersion. The adapter should not be placed where it could be submerged or in standing water.
• Use only specified communication cables: Connecting the adapter to an EL controller requires Gavita cables 906715, 906716, or 906717. Non-Gavita RJ45 cables may have different wiring configurations and are not confirmed compatible.

How to Install the Gavita E-Series LED Adapter 3-Way Splitter

Installation places the adapter inline between each 1700e fixture’s power cord and the power source, then links adapters together via RJ45 cables to form the controller network. The following steps reflect the product’s described installation method.

1. Power off all fixtures and the EL controller before beginning. Confirm that no fixture is energized before handling any cables or adapters.
2. Connect the adapter to the fixture power cord. The adapter runs inline with the power cord, meaning the fixture’s power cord plugs into the adapter rather than directly into the outlet or power strip.
3. Connect the adapter’s power output to the outlet or power strip. The adapter passes power through to the fixture while intercepting the control signal path.
4. Connect a Gavita RJ45 communication cable (906715, 906716, or 906717) from the EL controller to the first adapter in the chain. This establishes the control signal link between the controller and the first fixture.
5. Daisy chain subsequent adapters by connecting an RJ45 cable from the downstream port on the first adapter to the upstream port on the second adapter. Repeat for each additional fixture in the zone.
6. Verify all connections are seated before powering on. RJ45 connectors should click into place. Loose connections may result in the controller failing to detect or communicate with the fixture.
7. Power on the EL controller and fixtures. The controller should detect each adapter and the associated fixture. Refer to the EL controller documentation to confirm successful enumeration of all connected fixtures.
8. Test dimming and scheduling from the EL controller to verify each fixture responds correctly before placing plants under the lights.
