Growlink HUB Connection Cable (3M)

Wiring the Growlink HUB Connection Cable into Your LINKS System

The Growlink HUB Connection Cable runs a 3-meter (9 ft 10 in) line between any compatible LINKS device and the LINKS 8-Port Device HUB. It uses 8-conductor RJ-45 straight-through wiring terminated on standard RJ-45 jacks at both ends. The single cable carries 24VDC power and Modbus data together. That keeps each device on one port instead of pulling power and signal on separate runs. The wiring matches what the HUB documentation calls out for every port, so any 8-conductor RJ-45 cable to that spec drops in.

Planning Runs with a 3m LINKS Device RJ-45 Cable

At 3 meters, the run covers most layouts where the HUB sits just outside a flower room. The device end can land on a canopy frame, controller wall, or substrate tray inside the space. Growers running the 8-Port Device HUB usually allocate one cable per LINK device port. The canopyLINK, quadLINK, valveLINK, lightLINK, relayLINK, and Batch TankLINK family all use this same connector. Each draws within the HUB's 1A power budget. If a sensor lands farther out, this Growlink HUB accessory pairs with another drop to bridge the gap. A single LINKS automation cable rarely reaches a far-corner device on its own in larger rooms.

Key Features

• 3-Meter Length: Spans 9 ft 10 in from HUB port to device — long enough for most room-to-canopy runs.
• RJ-45 Straight-Through Wiring: Eight-conductor pinout matches every Growlink LINK device port and the HUB's documented spec.
• Power + Data on One Line: Delivers 24VDC and Modbus signal so each LINK draws everything from a single port.
• HUB-Native Connector: Plugs directly into Device Ports 1–8 on the LINKS 8-Port Device HUB with no adapter.
• Cultivation-Environment Build: Jacketing holds up to the temperature swings and humidity typical inside flower and veg rooms.
