3.3 Receiver Overview （Take FGR12B as an example）
CAUTION • Do not pull, bend or tie the receivers antenna or connect it to a servo.
3.3.3 Ports
These ports are used to connect the receiver to the various components of the model.
•
PPM/CH1: Connect to the servo, or output the PPM signal.
• CH1 - CH12: Can be connected to the servo, power supply or other components.
•
BVD/VCC: Used to detect the battery voltage and connect the power cable.
•
i-BUS in sensor interface (SENS/CH12/NPA): Used to connect each sensor.
•
bind button: Used to realize the bind between receiver and transmitter.
•
i-BUS out serial bus interface (SERVO/CH12/NPA): Connects i-BUS module to extend the channel and output i-BUS
or S-BUS signal.
•
For definition of the NPA~NPD interface, see the receiver's manual.
Note:
•
BVD function and NPA~NPD function will be implemented in the next version of firmware;
•
For this transmitter matched with the receiver, see the matching table on the official website. For specific operation
mode matched with other receivers, refer to the above contents.
3.3.1 Receiver Antenna
The FGR12B uses AFHDS 3 (third generation automatic frequency hopping digital system), which enables bi-
directional transmission.
CAUTION
• Keep the receivers antenna away from conductive materials such as carbon or metal.
To ensure normal function make sure there is a gap of at least 1cm between the
antenna and the conductive material.

3.3.2 Status Indicator
The status indicator is used to indicate the power and operating status of the receiver.
• Off: The receiver power is not connected.
• Steady red: The receiver is connected to the power supply and is working properly.
• Fast flashing: The receiver is in bind mode.
• Slow flashing: The paired transmitter is powered off or signal is lost.
