Example of standard PWM receiver connection：

Note:

[MODE] is the flight MODE control channel, and a three-stage switch channel on the remote control is used to switch modes;

[Serial RX/G] is a remote total sensitivity control channel. A scale knob or dial lever on the remote controller can be used for remote total sensitivity adjustment in flight, or a switch can be used for total sensitivity switching.

The electric adjustment or throttle steering gear is directly connected to the throttle channel of the receiver, without the need to go through the gyroscope;

When connecting, pay attention to the polarity of the signal line to avoid reverse insertion. Whether it is input or output channel, the orange signal line is facing up.

Serial receiver connection example

The A3 Pro V2 supports PPM and multi-protocol digital Serial receiver single-wire connection. If you use these receivers, just connect the output signal of the receiver to the [Serial Rx /G] interface of the gyroscope. When using a single-wire receiver, the A3 Pro V2 will use the default channel mapping table for channel identification. If the default channel sequence is different from the channel definition on your remote control, you will need to reset the channel mapping in the receiver menu. When using a standard PWM receiver, this channel mapping table does not work. When the A3 Pro V2 is operating in single-wire receiver mode, [THR OUT /AIL] outputs the throttle channel signal. If you are using a mini-receiver that does not have a separate output channel, you can connect the electrical or throttle steering gear to this interface.

Note:

The remote total sensitivity function is disabled by factory default in the single-wire receiver mode. If you need to use this function, please assign a corresponding channel number for the remote total sensitivity channel in the receiver menu.

When connecting, pay attention to the polarity of the signal line to avoid reverse insertion. Whether it is input or output channel, the orange signal line is facing up.

If Spektrum's satellite receivers are used, a separate dedicated adapter will be required to connect to the A3 Pro V2.

The Settings menu

Enter the menu

In the standby state, hold down the button for more than 2 seconds, and when the white light flashes quickly, release the button to enter the setting menu. The Settings menu contains 10 Settings items, which usually only need to be set once after the installation is completed and do not need to be changed frequently.

Select Settings Project

After entering the setting menu, the number of flashes of the white light represents the number of the current project, and it will automatically switch to the next project every 3 seconds, and keep repeating. For example, the white light flashes once, indicating that the first item is "airfoil setting". Wait 3 seconds, the white light flashes twice, indicating that the second item is "installation direction setting", and so on.

Change option values

When you reach the desired project, press the button once to enter the current setting item, after entering, the color of LED represents the current setting value, press the button once to switch to the next value, after modification is completed, wait about 5 seconds, LED will flash quickly to indicate that the current selected value has been automatically saved and returned to the setting menu; If you don't want to make the changes, just leave the current setting and wait 5 seconds to exit automatically.

Exit menu

Long press the button in the setting menu for 2 seconds until the white light flashes quickly and release the button to exit the setting menu and return to standby state.

Receiver menu

Enter the menu

Switch on the gyroscope power while holding down the button. When the purple light is on, release the button to enter the receiver menu. In the Receiver menu, you can change the receiver type and define the channel for the single-wire receiver mode.

Select Settings Project

After entering the receiver menu, the number of flashes of the purple light represents the number of the current item, and it will automatically switch to the next item every 3 seconds, and continue to cycle. For example, the purple light flashes once, that is the first item "receiver type selection", wait for 3 seconds, the purple light flashes twice, that is the second item "aileron channel setting", and so on;

Change option values

Short press the button once to enter the corresponding setting item, after entering the LED color represents the current setting value, short press the button once to switch to the next value, after the selection is completed, wait for about 5 seconds, the LED will flash quickly to indicate that the current selected value has been automatically saved and returned to the receiver menu; If you don't want to make changes, just leave the current setting and wait 5 seconds to exit automatically.

Exit menu

In the receiver menu, long press the button until the purple light flashes quickly and release the button to exit the receiver menu. After exit, the gyroscope will be reinitialized. Therefore, the receiver type or channel definition can take effect immediately without restarting.
