Tracer Nano RC connection to Pixhawk4 FC

PX4 Autopilot Flight Controllers 💻

Hi
Anybody knows how to connect the TBS tracer nano RX to the Holibro Pixhawk4 FC?
The pixhawk cable has only 3 wires: Ground, power, signal. The Tracer nano has 4 wires connections: ground, power, Rx, Tx.

Any idea?

Thanks
