3.4. Configuração do canal

The SR12+ features 12 configurable channel ports. Each port can be assigned as PWM, SBUS, FBUS, or S.Port. In ACCESS mode, CP1 can also function as SBUS In for redundancy. Refer to your transmitter's ETHOS system or similar interface for channel assignment.

• CP1: PWM / SBUS Out / FBUS / S.Port / SBUS In
• CP2-12: PWM / SBUS Out / FBUS / S.Port
• Observação: In ACCST mode, SBUS Out is assigned on Pin11 & S.Port is on Pin12.

4.4. Power Switch Function

The SR12+ includes a built-in power switch function. A dedicated socket allows connection of an external switch panel (optional) to control the receiver's power. This feature, combined with current overload wires on the channel ports, helps safeguard connected devices.

5. Manutenção

5.1. Atualizações de firmware (OTA)

The SR12+ supports Over-The-Air (OTA) firmware updates. This allows for convenient updates without physical connection, ensuring your receiver always has the latest features and improvements. Refer to the FrSky website or your transmitter's manual for OTA update procedures.

5.2. Manutenção da Antena

Ensure the detachable antennas are always securely connected and free from damage. Regularly inspect them for any kinks or cuts in the wire, which can affect signal performance. Proper antenna placement is crucial for maintaining optimal range and signal strength.

6. Solução De Problemas

6.1. LED Indicator Troubleshooting

Refer to the LED State table (Image 2.4) in the Product Overview section to diagnose common issues based on the receiver's LED behavior. For example, a Red LED ON indicates Failsafe mode.

6.2. Signal Issues

• Faixa ruim: Check antenna placement and ensure they are not obstructed or damaged. Perform a range check using your transmitter's functions.
• Interferência: The Archer Plus series features enhanced anti-RF-interference capabilities. However, ensure your setup avoids close proximity to high-power electrical components or other sources of electromagnetic interference.
• Failsafe Activation: If the receiver enters Failsafe mode (Red LED ON), it indicates a loss of signal from the transmitter. Verify transmitter power, range, and antenna connections on both the transmitter and receiver.
