3.2 Postup vázání

To establish communication between your FTr12B receiver and a compatible FlySky transmitter (AFHDS 3 protocol), follow these steps:

1. Ujistěte se, že je vysílač vypnutý.
2. Connect the binding plug (not included, typically a jumper wire) to the BIND port on the FTr12B receiver.
3. Apply power to the receiver (3.5-9V). The receiver's LED indicator should flash rapidly, indicating it is in binding mode.
4. Power on your FlySky AFHDS 3 compatible transmitter and navigate to the binding menu.
5. Zahajte proces párování na vysílači.
6. Jakmile je párování úspěšné, LED dioda přijímače se rozsvítí trvale.
7. Disconnect power from the receiver, remove the binding plug, and then reconnect power. The receiver should now be bound to your transmitter.

Poznámka: Refer to your specific FlySky transmitter's manual for detailed binding instructions, as procedures may vary slightly.

3.3 Umístění antény

Proper antenna placement is crucial for optimal signal reception and range. The FTr12B features dual antennas. Follow these guidelines:

• Mount the antennas at a 90-degree angle to each other to ensure diverse signal reception regardless of aircraft orientation.
• Keep antennas away from carbon fiber, metal parts, motors, ESCs, and other electronic components that can shield or interfere with the signal.
• Ensure the active part of the antenna (the last 31mm of the coaxial cable, without the outer insulation) is exposed and not bent sharply.
• Secure the antennas firmly to prevent movement during flight, using antenna tubes or appropriate mounting solutions.

3.4 Output Configuration (PWM/PPM/i.Bus/S.Bus)

The FTr12B supports multiple output protocols. The specific configuration method depends on your flight controller and transmitter settings. Generally, the output mode is selected via the transmitter's system menu or automatically detected by the flight controller.

• PWM (Pulse Width Modulation): Each channel has a dedicated pin. Connect servos or ESCs directly to the corresponding PWM pins.
• PPM (modulace polohy impulsů): All channels are multiplexed onto a single pin. Connect the PPM output pin to your flight controller's PPM input.
• i.Bus / S.Bus: These are serial bus protocols that transmit all channel data over a single wire, often with telemetry. Connect the i.Bus or S.Bus output pin to your flight controller's serial input.

Consult your flight controller's manual for specific wiring and configuration details for each protocol.

4. Návod k obsluze

4.1 Powering On and Initial Check

1. Ujistěte se, že všechna připojení jsou bezpečná a správná.
2. Power on your transmitter first.
3. Apply power to the FTr12B receiver. The receiver's LED should illuminate solid, indicating a successful link with the transmitter.
4. Verify that all control surfaces and functions respond correctly to transmitter inputs.

4.2 RSSI (Received Signal Strength Indication)

The FTr12B supports RSSI output, which provides real-time information about the signal strength between the transmitter and receiver. This data can be displayed on your transmitter or OSD (On-Screen Display) if your flight controller supports it. Monitoring RSSI is crucial for understanding your radio link quality and preventing flights beyond safe range.

4.3 Nastavení zabezpečení proti selhání

Bezpečnostní funkce Failsafe je klíčová bezpečnostní funkce, která definuje chování přijímače v případě ztráty signálu. Důrazně se doporučuje nakonfigurovat bezpečnostní nastavení na vysílači. Mezi běžné bezpečnostní možnosti patří:

• Držet: The receiver holds the last received command. (Not recommended for most aircraft).
• Žádný puls: The receiver stops sending pulses to all channels.
• Zvyk: Pre-set specific positions for each channel (e.g., throttle to zero, control surfaces neutral or slightly up for glide). This is the most recommended option for safety.

Always test your failsafe settings on the ground before flight to ensure they function as intended.

5. Údržba

5.1 Čištění a skladování

• Keep the receiver clean and free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning.
• Nevystavujte přijímač extrémním teplotám nebo přímému slunečnímu záření po delší dobu.
• Pokud přijímač nepoužíváte, skladujte jej v suchém a chladném prostředí.

5.2 aktualizací firmwaru

The FTr12B receiver supports online firmware updates. Regularly check the official FlySky website for the latest firmware versions. Firmware updates can improve performance, add new features, or fix bugs. Follow the instructions provided with the firmware update utility carefully to avoid damaging the receiver.

Ensure a stable power supply during the update process. Interrupting the update can render the receiver inoperable.

6. Řešení problémů

6.1 Žádný signál / LED dioda přijímače nesvítí trvale

• Zkontrolujte vazbu: Ujistěte se, že je přijímač správně spárován s vysílačem. V případě potřeby postup párování opakujte.
• Vysílač zapnut: Verify that your transmitter is powered on and operating on the correct model memory.
• Napájení: Confirm the receiver is receiving adequate power (3.5-9V). Check wiring and battery connections.
• Připojení antény: Ensure antennas are securely connected to the receiver and not damaged.
• Rozsah: Move the transmitter closer to the receiver to rule out range issues.

6.2 Intermittent Signal / Glitches

• Umístění antény: Re-evaluate antenna placement. Ensure they are clear of obstructions and mounted at 90 degrees to each other.
• Rušení: Check for potential sources of electrical interference near the receiver (e.g., motors, ESCs, video transmitters, high-current wires). Try to separate these components.
• Damaged Antennas: Inspect antennas for any cuts, kinks, or damage to the active element. Replace if damaged.
• Kolísání výkonu: Ensure the power supply to the receiver is stable and free from voltage kapky.

6.3 Incorrect Channel Response

• Nastavení vysílače: Verify channel assignments and mixing settings on your transmitter.
• Konfigurace letového ovladače: If using a flight controller, check its input mapping and calibration settings.
• Zapojení: Double-check that servos/ESCs are connected to the correct output pins on the receiver or flight controller.
