Variable RF Link technology:
RSSI signal output:
F version supports mixed protocols;
Frequency operation:
If the XR502 series receiver does not receive a signal within 15 seconds after power on, it enters the frequency matching mode (LED changes from slow flashing to flash), and then matches the frequency according to the controlled frequency matching operation. After completing the frequency conversion, the red LED remains on, indicating that a signal has been received.
Variable RF Link technology:
When the receiver is too close to the remote control, the RF signal will experience signal blockage, leading to loss of control. Variable RFLink technology is the key to solving this problem. When Variable RFLink detects that the receiver is close to the remote control, it will automatically lower the LNA gain and PA output power to avoid close range loss of control. When Variable RFLink detects that the receiver is far away from the remote control, it will automatically increase the LNA gain and PA output power to increase the receiver's working distance.
RSSI signal output:
There are two ways to output RSSI signals:
On the SBUS signal, the RSSI signal is output on the 16th channel (AUX12) of SBUS;
On the PPM signal, the RSSI signal is output on the 9th channel (AUX5) of the PPM;
Mixed protocol (only applicable to XR502-F version):
The XR502-F version supports both D8 and D16 protocols, allowing users to decide which protocol to use during frequency operations. When XR502-F is in frequency pairing mode, if the blue LED is on and the pairing is successful, RX will operate in D16 mode; If the blue LED is off and the frequency matching is successful, the RX will operate in D8 mode.
Dual antenna design;
Built in 13dBm LNA;
Use antennas that can be bent freely and are not easily broken;

Support simultaneous output of SBUS and PPM (cycle 22ms) signals;
If the XR502 series receiver does not receive a signal within 15 seconds after power on, it enters the frequency matching mode (LED changes from slow flashing to flash), and then matches the frequency according to the controlled frequency matching operation. After completing the frequency conversion, the red LED remains on, indicating that a signal has been received.
