RunCam 2 4K Version

■ Instruction Diagram

The RunCam 2 4K camera is depicted from the front and side. Key components are labeled with numbers:

• 1. WiFi/Mode Light (LED1)
• 2. WiFi/Mode Button
• 3. Power/Shutter Button
• 4. Power/Shutter Light (LED2)
• 5. MicroSD Card Slot
• 6. Micro-USB Port
• 7. Battery Holder

■ Charging

The Micro USB port supports DC 5-17V power supply. A DC 5V 1~2A charger is recommended. The Red LED will illuminate during charging and turn off when charging is complete. Full charging takes approximately 2 hours.

■ Low Battery Warnings

When powered on, if the battery charge is less than 15%, the Green LED will flash continuously for 5 seconds.

■ Basic Camera Operation

■ microSD Card

Insert the microSD card into the slot as indicated. Use reputable brand name memory cards (sold separately) that meet these requirements:

• Card Type: microSD, microSDHC, or microSDXC.
• Speed Class: U3 is recommended for resolutions like 2.7K60/1080P120. Other resolutions require U1 or above.
• Capacity: Up to 128GB.

A diagram shows the side of the RunCam 2 4K camera with the MicroSD card slot labeled. An arrow indicates a MicroSD card being inserted into the slot.

NOTICE: Handle memory cards with care. Avoid liquids, dust, and debris. Power off the camera before inserting or removing the card. Consult manufacturer guidelines for acceptable temperature ranges.

Abnormal SD Card Status: If the blue light continues to flash quickly after powering on, it indicates the SD card is not inserted, is full, or cannot be recognized.

■ Connection to Computer

After turning on the camera, connect it to your computer via a USB cable. It should be recognized as a removable disc.

A diagram illustrates connecting the RunCam 2 4K camera to a laptop computer using a Micro-USB cable. The camera is shown on the left, followed by the cable, and then a laptop on the right.

NOTICE: If the camera is not recognized by the computer, ensure the microSD card is properly inserted. If the microSD card information cannot be read normally, try using a different micro USB cable or USB port on the computer.

■ Firmware Upgrade

To ensure optimal camera performance, always use the latest firmware. The update method can be found here: https://runcam.com/download/RC2-4K4kversion.

■ Flight Controller Connection and Control

USB TV-out Cable Instruction:

• Remote control wire: This wire can be soldered to an unoccupied 'S' or 'LED' pad on the Flight Controller to enable remote control of your camera.
• Ground wire: Serves as both the power ground wire and the remote control signal ground wire.
• Video wire: This wire can be soldered to the 'VI' pad on the Flight Controller or the 'Video-in' pad on the VTX to transmit the video signal to the VTX.
• Power wire: Supports external power input ranging from DC 5V to 17V.

Example: Connecting to a Speedy Bee-F7 Flight Controller

Solder the remote control wire from the USB TV-out cable to the S5 pad on the Speedy Bee-F7. Connect the GND wire to any 'G' pad, the Video wire to the 'VI' pad, and the Power cable to the 5V pad.

A diagram shows the USB TV-out cable connections to a flight controller. The cable has four wires: a white wire for Remote Control, a black wire for Ground (GND), a yellow wire for Video, and a red wire for Power. These are shown connecting to corresponding pads on a flight controller board labeled 'Remote Control', 'GND', 'Video', and 'Power'.

■ CLI Setting

If you have soldered the remote control wire to the S5 pad as described above, you will need to perform three steps to configure the CLI interface:

1. Connect to your flight controller's ground station software to enter the CLI interface. Then, type the command resource.
2. Locate the line for resource motor 5 and note its associated pinio, which should be A08.

A command-line interface (CLI) window displays text related to flight controller configuration. It shows messages like 'Building AutoComplete Cache Done!' and lists resources such as 'resource BEEPER 1 C13', 'resource MOTOR 1 C06', up to 'resource MOTOR 5 A08', and 'resource SERIAL TX 1 A09'. Below this, commands are shown: 'resource motor 5 none', 'resource pinio 2 A08', 'set pinio_config = 129,129,1,1', 'set pinio_box = 0, 41, 255, 255', and 'save'.

3. Type the following commands:

resource motor 5 none
resource pinio 2 A08
set pinio_config = 129,129,1,1
set pinio_box = 0, 41, 255, 255
save

■ Remote Controller Setting

1. Mode Setting

Connect to the BetaFlight ground station software. Navigate to the 'Modes' interface and find the 'USER2' mode. Assign 'USER2' to an SD switch on your controller. For example, if AUX3 is chosen, the SD switch will correspond to AUX3. Select the second or third level of the switch to achieve the desired setting. The camera can then be controlled via the SD switch to start/stop recording or change modes, provided the interface is configured accordingly.

A screenshot of the Betaflight configurator software shows the 'Modes' tab. It displays a list of assignable modes, including 'USER2', with options to assign them to specific switches or channels. The interface indicates that USER2 can be assigned to AUX3.

2. Assign Channel to Switch (FrSKY X9D Example)

On your controller, choose the Model and then enter the 'MIXER' interface to assign a channel to a switch. Using OpenTX 2.2.0 as an example, CH7 is assigned to the 'SD' switch.

A screenshot of a FrSky X9D digital telemetry radio system displays the 'MIXER' interface. It shows channel assignments, with CH7 specifically assigned to the 'SD' switch.

3. Test

Set the SD switch to the bottom position. Toggle the switch once to start/stop recording. Toggle it thrice to switch the camera to photo mode.
