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

1. Introduktion

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.

• [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: Statusindikatorlys.
• [7] Signal pin: Output for control signal.
• [8] Power anode: Positive power input.
• [9] Power cathode: Negative power input (Ground).

Note: 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. Opsætning og binding

4.1 Ledningsforbindelser

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 Bindende procedure

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. Sørg for, at din sender er slukket.
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. Betjeningsvejledning

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.

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

6. Vedligeholdelse

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

• Miljøforhold: 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.
• Rensning: Hold receiveren ren og fri for støv, snavs og fugt. Brug en blød, tør klud til rengøring. Undgå at bruge opløsningsmidler eller skrappe kemikalier.
• Antennepleje: Ensure the antenna is not cut, bent sharply, or damaged. A damaged antenna can significantly reduce range and signal reliability.
• Firmwareopdateringer: The receiver supports online updates. Periodically check the official Flysky webwebstedet for tilgængelige firmwareopdateringer for at sikre optimal ydeevne og adgang til nye funktioner.

7. Fejlfinding

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

• Modtager er ikke bindende:
  • 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.
• No Control Response:
  • 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.
• Short Range or Intermittent Signal:
  • Inspect the receiver antenna for any damage, kinks, or improper routing. Ensure it is positioned away from metal objects.
  • Avoid operating in areas with high 2.4GHz interference.
  • Ensure the transmitter's battery is adequately charged.
• LED-indikatorproblemer:
  • 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.
