The TrolMaster ECS-4 is a 16-foot (4.88 m) communication extension cable specifically designed for the AMP-2 sensor board in the Aqua-X NFS-1 irrigation system. It extends the connection between the AMP-2 and NFS-1 controller when the standard 2.5-meter cable is not long enough, allowing the AMP-2 to remain near the reservoir or sampling point while the NFS-1 controller can be installed elsewhere. It is a plug-and-play extension requiring no configuration, signal converter, or firmware changes.

• Compatible Controller: Aqua-X NFS-1
• Function: Extends communication between AMP-2 and NFS-1
• Installation: Plug-and-play; no tools or configuration required
• Signal: Carries AMP-2 communication signal for pH, EC and water-temperature monitoring
• Compatible Probes via AMP-2: PPH-1, PPH-2, PCT-1 and PCT-2
• Operating Temperature: 32–122°F (0–50°C)
• Operating Humidity: ≤90% RH
• Package Dimensions: 156 × 83 × 30 mm
• Sold Separately: Yes; AMP-2 sensor board is not included
• Multiple Extensions: TrolMaster does not publish an official specification for daisy-chaining multiple ECS-4 cables
• Important Compatibility: Not for direct connection to PPH/PCT probes and not compatible with Hydro-X HCS-1
Key Advantage: The ECS-4 allows the AMP-2 to be positioned where the water-quality probes actually need to be located, while extending its communication connection back to the NFS-1 controller by 16 feet. This is particularly useful when the controller and reservoir are separated by a significant distance.
