CL-55 cloud connectivity device

Simplify connectivity, one device

Fleet management, automatic data transfer, and NTRIP and optional RTK radio for correction services

Product Info

Manage the fleet, upload data to TAP, or enable autosteering accuracy.

The CL-55 is a multifunctional cellular telematics device designed for fleet monitoring and connectivity in key applications, including autosteering correction services and grain cart harvest data upload. It provides fleet tracking and machine metric monitoring for many agricultural machines, automatic data upload to Topcon Agriculture Platform (TAP), and position correction service access via NTRIP or an optional RTK radio.

Cloudlynk connectivity devices serve as TAP’s backbone. This cloud-based farm management system manages mixed-fleet data seamlessly from the field – collecting, analysing, visualising, and delivering actionable insights. Though compatible with all TAP subscriptions, the CL-55 is required to use TAP Fleet or the Grain Cart add-on.
