5. Konfigurazioa
5.1 Binding Process (Registration and Binding)
The Archer Plus R8 receiver supports both ACCESS and ACCST D16 protocols. The RF protocol is automatically matched during the binding process.
- Izen ematea:
- Turn on your transmitter and navigate to the RF System menu.
- Select the appropriate external or internal RF module (e.g., ACCESS or ACCST D16).
- Choose the 'Register' option.
- Press and hold the REG button on the receiver while connecting the battery. The Green and Red LEDs on the receiver will illuminate, indicating registration mode.
- Select 'Register' on your transmitter. The Green and Red LEDs on the receiver will flash, indicating successful registration.
- Itzali hargailua.
- Koadernaketa:
- Select the receiver (e.g., RX1) and choose the 'Bind' option on your transmitter.
- Connect the battery to the receiver. The Green and Red LEDs will illuminate.
- Select 'Bind' on your transmitter. The Green LED will turn on and the Red LED will turn off, indicating successful binding.
- Power off the receiver and then power it on again. The Green LED should be solid, indicating normal operation.

5.2 Kableatutako konexioak
- PWM Channels (CH1-CH8): Connect your servos or other PWM-controlled devices to the corresponding channels.
- SBUS OUT: Provides a single serial output for all channels, suitable for flight controllers or other SBUS-compatible devices.
- SBUS IN: Allows the R8 to function as a primary receiver in a redundant setup when connected to another FrSky receiver with an SBUS Out port.
- FBUS: The FBUS protocol enables seamless pairing with multiple telemetry devices (e.g., XACT servos, ADV Sensors) and simplifies build setup.
- AIN2: Used for external battery or device voltage detection (0-35V, 1:10 divider ratio).
5.3 Antenen instalazioa
The Archer Plus R8 features dual detachable antennas. For optimal reception and range, ensure the antennas are mounted at a 90-degree angle to each other and away from carbon fiber, metal, or other conductive materials that could shield the signal. Avoid bending the antenna tips excessively.
6. Funtzionamendua
6.1 LED Status Indicators (ACCESS)
The receiver's LED indicators provide visual feedback on its current status:

6.2 Telemetria
The Archer Plus R8 supports telemetry via S.Port or FBUS. Telemetry allows you to monitor real-time data from your model, such as receiver voltage, signal strength (RSSI), and external sensor data, directly on your transmitter screen.
- S.Port: Smart Port is FrSky's proprietary full-duplex digital transmission interface, allowing for two-way communication with S.Port enabled sensors.
- FBUS: FBUS simplifies wiring by allowing multiple FBUS-compatible devices to be connected in series, reducing the number of cables required for telemetry.
6.3 Over-The-Air (OTA) Firmware Update
The receiver supports OTA firmware updates, allowing you to update the receiver's firmware wirelessly via your compatible FrSky transmitter. Refer to your transmitter's manual for specific instructions on performing OTA updates.
6.4 Black-Box Function
The integrated Black-Box function records basic flight data, primarily related to power and signal. This data can be useful for diagnosing issues or analyzing flight performance. Access and manage this data through your transmitter's menu.

Image: Screenshot of a transmitter's menu displaying 'Flight Data Record' options, including various reset functions for power on, RF, wake up, unbinding, linkup, and brown out detection. This menu is used to manage the Black-Box function.
6.5 Barrutiaren egiaztapena
Before each flight, perform a range check to ensure adequate signal strength. This is typically done by placing the transmitter in range check mode (which reduces RF power) and walking a specified distance away from the model while monitoring telemetry data (e.g., RSSI).

Image: Screenshot of a transmitter's display showing 'Range Check' results, including 2.4G RX, 2.4G VFR, 2.4G RSSI, 900M RX, 900M VFR, and 900M RSSI values. This indicates the signal quality during a range test.
