Command Bus Cable - Hydros

The Hydros Command Bus Cable serves as the backbone of a Hydros device network, transmitting both data and power over a single 5-pin connection. Rather than running separate power and communication lines between modules, a single Command Bus Cable handles both functions, keeping installations clean and reducing cable clutter in sump cabinets.

Because this is a combined data and power cable, it allows compatible Hydros devices to draw power from an upstream unit while simultaneously exchanging control signals. This is particularly useful when expanding a Hydros setup — adding probes, expansion modules, or additional controllers without introducing additional power bricks or wiring runs.

Four length options are available: 1 ft, 3 ft, 6 ft, and 14 ft. Shorter runs suit side-by-side module mounting, while the 14 ft option provides enough reach for larger systems where devices are spread across a sump cabinet or equipment rack. Select the length that matches your physical layout to avoid unnecessary slack or tension on the connectors.

This cable is a replacement or expansion part intended for aquarists already running Hydros hardware. Verify compatibility with your specific Hydros modules before ordering, as the Command Bus connection is specific to the Hydros ecosystem.
