Flysky FS-R4M 2.4GHz 4-Channel ANT Protocol RC Receiver Instruction Manual

Model: FS-R4M

1. Introduzione

The Flysky FS-R4M is a compact 4-channel mini receiver designed for use with RC models, specifically mini and micro cars. It operates on the 2.4GHz ISM band using the advanced ANT protocol, offering reliable bidirectional communication. This receiver features a single external antenna and provides PWM output for control signals.

It is compatible with Flysky transmitters that support the ANT protocol, such as the FS-G7P. Its ultra-small size and lightweight design make it an ideal choice for applications where space and weight are critical considerations.

  • [1] CH1: Channel 1 PWM Output
  • [2] CH2: Channel 2 PWM Output
  • [3] CH3: Channel 3 PWM Output
  • [4] CH4: Channel 4 PWM Output
  • [5] Antenna: Single external antenna for signal reception.
  • [6] LED: Indicatore luminoso di stato.
  • [7] Signal pin: Output for control signal.
  • [8] Power anode: Ingresso di potenza positivo.
  • [9] Power cathode: Ingresso di alimentazione negativo (terra).

Nota: The interface specifications for the connectors are ZH1.5mm-3P, commonly known as JST-PH2.0. Standard RC servo connectors (Futaba style) are not directly compatible and will require adapter cables or modification.

4. Configurazione e rilegatura

4.1 Collegamenti di cablaggio

Connect your servos, Electronic Speed Controller (ESC), and other components to the corresponding channels on the FS-R4M receiver. Ensure correct polarity for power connections (Power anode [8] for positive, Power cathode [9] for negative/ground, Signal pin [7] for signal).

As noted in the product overview, the receiver uses ZH1.5mm-3P (JST-PH2.0) connectors. If your servos or ESC use standard Futaba-style connectors, you will need to use appropriate adapter cables or modify the connectors. Ensure all connections are secure before proceeding.

4.2 Procedura vincolante

The binding process links your FS-R4M receiver to your Flysky ANT protocol transmitter. Refer to your specific transmitter's manual for detailed binding instructions, as procedures may vary slightly. A general binding sequence is as follows:

  1. Assicurarsi che il trasmettitore sia spento.
  2. Connect power to the FS-R4M receiver. The LED [6] on the receiver will typically flash, indicating it is in binding mode or awaiting a signal.
  3. Place your transmitter into binding mode. This usually involves holding a specific button (e.g., "BIND" button) while powering on the transmitter. Consult your transmitter's manual for the exact steps.
  4. Once the receiver and transmitter successfully bind, the LED on the receiver will change to a solid state, indicating a successful connection.
  5. Release the bind button on the transmitter and power cycle both the transmitter and receiver to confirm the binding.

If binding fails, ensure the receiver is within range of the transmitter and that both devices are using the ANT protocol. Repeat the steps if necessary.

5. Istruzioni per l'uso

After successful binding, the FS-R4M receiver will output PWM signals corresponding to the commands from your transmitter. Ensure all control surfaces and functions respond correctly before operating your RC model.

  • Sequenza di accensione: Always power on your transmitter first, then the receiver. When powering off, disconnect power from the receiver first, then power off the transmitter.
  • Controllo della portata: Perform a range check before each use, especially in new environments, to ensure reliable signal strength.
  • Interferenza: Avoid operating near sources of 2.4GHz interference (e.g., Wi-Fi routers, other 2.4GHz RC systems) to prevent signal loss.

6. Manutenzione

Proper care and maintenance will extend the lifespan of your FS-R4M receiver.

  • Condizioni ambientali: Operate and store the receiver within the specified temperature range of -10°C to +60°C and humidity limit of 20% to 95%. Avoid extreme temperatures and high humidity.
  • Voltage and Safety: Always pay attention to the input voltage range (3.5-9V/DC) and ensure it is not exceeded. Incorrect voltage can damage the receiver.
  • Pulizia: Mantenere il ricevitore pulito e privo di polvere, sporco e umidità. Utilizzare un panno morbido e asciutto per la pulizia. Evitare l'uso di solventi o prodotti chimici aggressivi.
  • Cura dell'antenna: Ensure the antenna is not cut, bent sharply, or damaged. A damaged antenna can significantly reduce range and signal reliability.
  • Aggiornamenti del firmware: The receiver supports online updates. Periodically check the official Flysky websito per gli aggiornamenti firmware disponibili per garantire prestazioni ottimali e l'accesso alle nuove funzionalità.

7. Risoluzione Dei Problemi

If you encounter issues with your FS-R4M receiver, consider the following troubleshooting steps:

  • Ricevitore non vincolante:
    • Ensure both the transmitter and receiver are powered on and within close proximity during the binding process.
    • Verify that your transmitter supports the ANT protocol.
    • Check the LED status on the receiver; it should indicate binding mode (e.g., flashing).
    • Refer to your transmitter's manual for specific binding instructions.
  • Nessuna risposta di controllo:
    • Confirm the receiver is successfully bound to the transmitter (solid LED).
    • Check all wiring connections between the receiver, ESC, and servos for correct polarity and secure fit.
    • Ensure the power supply to the receiver is within the specified voltage range (3.5-9V/DC).
    • Verify that the transmitter is powered on and functioning correctly.
  • Segnale a corto raggio o intermittente:
    • Inspect the receiver antenna for any damage, kinks, or improper routing. Ensure it is positioned away from metal objects.
    • Evitare di utilizzare il dispositivo in aree con forti interferenze nella banda dei 2.4 GHz.
    • Ensure the transmitter's battery is adequately charged.
  • Problemi relativi agli indicatori LED:
    • If the LED does not light up, check the power connection to the receiver.
    • Refer to the transmitter manual for specific LED indications during binding and operation.
