Neptune Systems 1 FT Aquabus Cable – Compact, Reliable Control Extension

  The Neptune Systems 1 FT Aquabus Cable makes connecting Apex modules seamless, whether you're expanding your setup or organizing tight cabinet spaces. As part of the Neptune Systems control ecosystem, this short extension supports both daisy-chain and star configurations—offering maximum flexibility for modern reef automation. You'll find it in our Aquarium Monitoring & Automation Gear section for good reason—it’s compact, dependable, and designed to work flawlessly with your Apex or Apex EL controller.

Why Choose the Neptune Systems Aquabus Cable?

Though it resembles a USB cable, this 1-foot Aquabus is made specifically for Neptune Apex systems—and should never be used with standard USB devices. Plugging into a computer or non-Neptune product could permanently damage your gear. This cable supports:

• Neptune Apex and Apex EL controller connectivity
• Star or daisy-chain topology arrangements
• Reliable signal transmission with shielded ends
• Quick module swaps with minimal slack

Frequently Asked Questions About the Neptune Systems Aquabus Cable

Q:Is the Aquabus Cable the same as a USB cable?

A: No—while it looks like a USB cable, it’s designed exclusively for Neptune Systems. Using it with other USB devices may cause hardware damage.

Q:What is the maximum number of Aquabus cables I can chain?

A: There’s no hard limit. Neptune recommends clean layout organization using star or daisy-chain topologies to maintain reliability.

Q: Will this cable work with the older Apex Classic?

A: Yes, the 1 FT Aquabus Cable works with all Apex models that feature an Aquabus port.

Q: Can I connect multiple Energy Bars with this cable?

A: You can, although longer Aquabus cables (3 FT, 6 FT, 15 FT) may be more appropriate for larger setups.

Q: Is this cable required for every Apex module?

A: Only if you’re linking modules across distances. The 1-foot cable is perfect when devices are positioned closely together.
