The JETI Duplex 2.4EX Central Box 220 is an advanced power management and control system for models using powerful and power-hungry servos. As the successor to the popular Central Box 200, it features an aluminum housing and advanced over-current protection for servo slots. The Central Box 220 offers true battery redundancy, DITEX servo telemetry, JETI EX telemetry, and supports up to three receiver inputs (2x 2.4GHz and 1x 900MHz) for robust RF signal redundancy.
Configuration via JETI Duplex DS/DC Transmitters
The full potential of the Central Box 220 can be harnessed through JETI Duplex DC/DS transmitters. The device overview on these transmitters simplifies the entire configuration process, including servo outputs, telemetry settings, function assignments, and more.
Switching On and Off
The switching on and off process of the Central Box 220 is controlled using the supplied magnetic switch, ensuring reliable power management.
Recommended Receivers
Two compatible RSat2 receivers are included in the package. For additional functionality, a REX Assist receiver can be used in combination with an RSat2 receiver, providing gyro stabilization.
