The HGLRC ELRS Gemini RX is a high-performance dual diversity receiver designed for FPV drones, offering enhanced signal reliability and range. Key features include:

• Dual Communication Link: Antennas operate simultaneously at different frequencies for superior anti-interference performance.
• True Diversity Dual Reception: Integrates dual-channel SX1276 (2.4G version SX1281) and dual-channel PA/LNA for robust signal acquisition.
• TCXO Temperature-Compensated Crystal Oscillator: Ensures accurate frequency stability, preventing signal loss in extreme temperatures.
• Direct Plug-in Connection: Facilitates easy installation and quick replacement without soldering, while retaining pad design for flexibility.
• High Return Power: ELRS 2.4G version offers up to 100mW return power (915M version up to 50mW).
• Advanced ELRS Protocol: Provides long-distance remote control, low latency, and refresh rates up to 1000Hz (200Hz for 915M).

• 5V: Power input (5 Volts).
• TX: Transmitter data output from receiver (connect to RX on flight controller).
• આરએક્સ: Receiver data input to receiver (connect to TX on flight controller).

૩.૨. બંધનકર્તા પ્રક્રિયા

To bind your HGLRC ELRS Gemini RX receiver to your ExpressLRS transmitter, follow these steps:

1. Power on your receiver three times in quick succession. The LED on the receiver should start flashing with an orange double flash, indicating it is in binding mode.
2. Ensure your ExpressLRS transmitter module is also in binding mode. Refer to your transmitter's manual for specific instructions.
3. Once the receiver and transmitter successfully bind, the receiver's LED will turn solid, indicating a stable connection.

નોંધ: If the RGB LED flashes orange three times after binding, it indicates that the model matching settings do not align. You may need to adjust the Model Match (ID:X) setting on your remote control (SYS → TOOLS → ExpressLRS → Model Match ON (ID:X)) or set it to Model Match OFF (ID:X).

5.3. ફર્મવેર અપડેટ

The HGLRC ELRS Gemini RX uses ExpressLRS firmware. For optimal performance and access to the latest features, it is recommended to keep your receiver's firmware updated. Firmware updates are typically performed via the ExpressLRS Configurator. Connect the receiver to your computer using a USB-to-UART adapter (not included) and follow the instructions provided by the ExpressLRS project.

6.1. સૂચક સ્થિતિ

The receiver features an RGB LED that indicates its current status. Understanding these indicators is crucial for proper operation and troubleshooting.

છબી 6.1: Table detailing the RGB LED indicator status descriptions and a color gradient for 2.4G refresh rates on the HGLRC ELRS Gemini RX.

* If RGB orange flashes three times, you can enter the remote control SYS → TOOLS → ExpressLRS → Model Match ON (ID:X), or set it to Model Match OFF (ID:X).

6.2. Refresh Rate Indication

When the receiver is connected, the steady LED color indicates the current refresh rate. Refer to the color gradient provided in Image 6.1 for specific refresh rate interpretations (e.g., F1000, F500, D500, D250, 500Hz, 333Hz, 250Hz, 150Hz, 100Hz, 50Hz).

નોંધ: F1000 and F500 are refresh rates in FLRC mode, offering faster modulation and lower latency. D500 and D250 are refresh rates in DVDA (Deja Vu Diversity A/D) mode, suitable for competition, where the receiver sends the same data packet multiple times for enhanced reliability.

• કોઈ શક્તિ નથી: Check all power connections (GND, 5V) to ensure they are secure and correctly polarized. Verify the power source is providing the correct voltage.
• No Connection (Flashing Orange Slowly): Ensure your transmitter is powered on and transmitting. Re-attempt the binding procedure (Section 5.2).
• Radio Frequency Chip Not Detected (Red Light Flashes Quickly): This indicates a hardware issue. Ensure the receiver is correctly powered and inspect for any visible damage. If the issue persists, contact support.
• Model Matching Issue (Three Orange Flashes): Adjust the Model Match setting on your remote control as described in Section 5.2.
• Poor Range/Signal Loss:
  • Check antenna placement and orientation. Ensure they are not obstructed by carbon fiber or other conductive materials.
  • નુકસાન માટે એન્ટેનાનું નિરીક્ષણ કરો.
  • Verify that the transmitter power output is set correctly.
  • Ensure both receiver and transmitter firmware are up to date.
