## What is Vireo?

The JCA VIREO is an evolution of the ISOBUS Virtual Terminal (VT) to combine the implement compatibility benefits of the ISOBUS (ISO11783) standard with the technology capabilities of tablet devices. The VIREO is a tablet-based ISOBUS VT solution that can eliminate the need for expensive ISOBUS terminals. The VIREO consists of any of the JCA Wi-Fi enabled devices and the JCA VIREO app. The JCA controller connects to a tractor’s ISOBUS network, and communicates the relevant ISOBUS VT messages over Wi-Fi to a tablet running the VIREO app. The VIREO app then performs the functions of an ISOBUS compatible Virtual Terminal (or Universal Terminal), allowing monitoring and control of ISOBUS compatible implements.
