Testo Databus Connection Cable 5m

This is the Testo databus connection cable, purpose-built for linking your Testo 350 Control Unit with various analyzer boxes. It's essential for anyone on the tools doing emissions testing or combustion analysis, ensuring your critical data flows reliably.

Having a spare cable like this can save a stack of time when you're out on a job and a connection gets flaky, especially on dusty industrial sites where reliable data transfer is non-negotiable.

Best For

• HVAC technicians performing emissions analysis.
• Industrial maintenance teams managing combustion systems.
• Engineers conducting compliance testing with Testo 350 systems.

Compatibility

This cable is specifically designed for the Testo databus system, connecting the Control Unit to analyzer boxes or linking multiple analyzer boxes. It's compatible with the Testo 350 series, including models like the Testo 350 Portable Emission Analyzer, Boiler and Burner Kit, Engine Kit, Turbine Kit, Process Kit, and the Mining Compliance Tuning Kit. If you're running a different model, check fittings and specs before ordering.

Features

• Purpose-built for the Testo databus system, ensuring seamless communication between your Testo 350 components.
• Features a robust bayonet fitting for secure and quick connections, essential for field work.
• Generous 5-metre length provides flexibility when setting up your analysis equipment on site.
• Durable plastic housing designed to withstand typical industrial and HVAC environments.

Technical Specifications

What's in the Box

• 1 x Testo databus connection cable with bayonet fitting, 5 m length.

Using It on the Job

1. Always ensure your Testo 350 Control Unit and analyzer boxes are powered off before connecting or disconnecting the cable.
2. Align the bayonet fitting on the cable with the corresponding port on your Testo equipment.
3. Push gently and twist the fitting until it locks securely into place. You should feel a positive engagement.
4. Verify all connections are tight before powering on your equipment to prevent data loss or connection issues.
5. Once testing is complete, carefully disconnect the cable by twisting the bayonet fitting to release it and pulling straight out.
6. Store the cable coiled loosely to prevent kinking or damage to the internal wiring.

Limitations & Safety Notes

• This cable is for data transfer only; do not attempt to use it for power supply.
• Only use with compatible Testo 350 series equipment as specified by Testo.
• Avoid bending the cable sharply or placing heavy objects on it, which can damage internal conductors.
• Inspect the cable and connectors regularly for any signs of wear or damage before use to ensure reliable operation.

Tradie Pro Tip

Always run a quick data integrity check or a short test sequence after setting up your Testo 350 with this cable. It's a lot easier to troubleshoot a connection issue on the ground than halfway through a stack test at height.
