OptiLink is a free Android mobile app that allows drivers and fleet operators to monitor and control trailer functions wirelessly. It provides access to 19 separate trailer functions, including suspension, axles, braking, and security functions. OptiLink also offers real-time condition monitoring, fast and easy access to critical trailer data, and 17 language options.

The app offers a simple tool called "Show Me Your Trailer," which presents trailer information at-a-glance. Axle Load presents axle load information in tones, indicating total load across all axles and load on each individual axle, while providing an automatic warning when the axle load exceeds pre-programmed limits. Vehicle Inclination indicates the angle of inclination for the trailer, with an automatic warning if a defined threshold is exceeded.

OptiLink also offers a range of automatic alarms tasked to monitor safety-critical parameters and activities, improving safety by allowing a trailer to be controlled from the cab or at a safe distance from the unit. The app requires additional hardware (OptiLink™ ECU)) and is an excellent option for truck drivers and fleet operators looking for complete control of their trailer.
