🔌 Interface & LED Indicators (Figure 1)

🔵 Blue LED — Receiver Status

• Fast Flashing: Receiver is connected

• Slow Flashing: Receiver is waiting for transmitter signal

• Solid: Receiver has successfully received the transmitter signal and is working normally

🔴 Red LED — Transponder Status

• Off: Transponder is off or not detected

• Solid: Transponder is active and functioning

📶 LNA Function

The Low-Noise Amplifier (LNA) is an electronic component designed to improve both the operating distance and response speed of the receiver. It is especially effective when using transmitters with lower signal output, greatly enhancing control feel and precision for drifting or racing models.

🔗 Binding Operation

1. Power on the receiver

2. Press and hold the BIND switch until the blue LED flashes rapidly

3. Turn on the transmitter and initiate the binding procedure

4. When the blue LED turns solid, the receiver is successfully bound to the transmitter

🔁 Switching Output Modes (3.4ms / 6.8ms)

The RXC52-SP&TP supports two output modes:

• 3.4ms mode for high-speed response

• 6.8ms mode for standard compatibility

Mode Switching Logic:

• If using T7PX or T10PX:

  • SFHSS Analog mode → 6.8ms

  • SFHSS Digital mode → 3.4ms

• For other transmitters:

  • S-FH (NORM) mode → 6.8ms

  • S-FH (HIGH) mode → 3.4ms

🆔 Editing the Transponder's Personal ID

The RXC52-SP&TP features an integrated transponder that allows users to set their custom personal ID number.

To edit the ID:

1. Connect the receiver to your PC using the MX USB PG-ISP

2. Launch the MX GUI software

3. Use the visual editing tool to assign your preferred personal ID (Figure 4)

4. Ensure connection is made properly as shown in Figure 3
   
   

⬆️ Online Firmware Upgrade

• This function is supported via the MX GUI software

• Requires MX USB PG-ISP for connection

• Make sure the transmitter is turned off when connecting the receiver to the GUI

• The receiver cannot be connected to the GUI if the transmitter is on
