AirWay is an electronic device that wirelessly transmits and receives up to 4 input/output control signals. It can be used to provide remote I/O for products such as Whiting Passport’s Liftlog™ or Liftlog XL data logger, where the desired signals cannot be cabled into the logger directly. Alternatively, two AirWay units can be used together to provide up to 4 virtual connections.

Why install an AirWay?

Advanced data loggers require one or more input signals from existing instrumentation or additional sensors. It is not always possible or practicable to physically connect these signals using traditional cabling.



  • Provides up to four remote inputs for other devices.
  • Four contact outputs, rated for 250V AC/32VDC, 4A.
  • Long range (500m line of sight) between two units.
  • Wide input power range (24-240V AC/DC).
  • Wireless configuration via Bluetooth.

When do I need an AirWay?

When you have to get a control signal from one place to another (e.g. crane to crane OR crane to ground) and cabling the signal is expensive or impractical.

Do I need one unit or two?

If you are using AirWay as a remote input for Liftlog or LiftlogXL then you only need 1 unit. Otherwise, you will need two units.

What is the range?

When installed in such a way as to create an uninterrupted path (ie line of sight) between the two units (either two AirWay units or an AirWay and a Liftlog™ or LiftlogXL), range is approximately 500m.

When one AirWay unit is in a metal enclosure, subtract 150m, and when both units are in metal enclosures, subtract 300m. When the transmission path is not line of sight, range is difficult to predict but is usually around 100-200m.

Will it fail safe?

Yes. An output signal is provided to indicate that you have a good connection.
