RunCam Racer MCK Edition USER MANUAL

Joystick Control & UART Control Switchable

The RunCam Racer MCK Edition camera supports both Joystick Control and UART Control, which can be switched. The current control mode is displayed in the top-left corner of the screen. The default mode is Joystick control.

Switching Control Modes

To switch modes:

1. Short the two camera control pins.
2. Power on the camera. The camera will automatically switch between the two modes.

Note: The selected mode is saved after power off. Once the desired mode is active, unplug the short-circuit cable.

Visual Description of Mode Switching: The manual illustrates two states: "JOYSTICK CTRL" displaying a timer and voltage, and "UART CTRL" displaying a timer and voltage, indicating the camera's active control mode.

UART Control Compatibility

UART Control is compatible with the following flight controllers:

• BetaFlight 3.3 or above
• ButterFlight 3.4 or above
• CleanFlight 2.2 or above
• Kiss Flight RC36 or above

Wiring and Configuration

Joystick Control Wiring

Diagram Description: Shows connections from the camera (VBAT+, GND, Video out) to a power source and display. It also indicates a connection for an OSD Key-press Board (not included).

Connections:

• To VBAT+: 5-36V in
• GND
• Video out
• VBAT+

UART Control Wiring

Diagram Description: Illustrates connecting the camera's UART pins (TX, RX) to a flight controller's UART pins (e.g., UART3 RX3, TX3). The RunCam TX200 component is shown with its power and ground connections.

Example: Connecting to UART3.

Flight Controller Wiring:

• RunCam TX200 (3.5-5.5v in, GND)
• Flight controller RX3 (connected to RunCam TX)
• Flight controller TX3 (connected to RunCam RX)

Betaflight Configuration

Diagram Description: A table details Betaflight configuration settings for different UART ports, including Identifier, Configuration/MS Serial Rx, Telemetry Output, Sensor Input, and Peripherals for UART1 through UART5.

Key Settings for UART3 (Example):

UART Control Operation

The manual describes two modes of UART control operation, indicated by connection status and buzzer feedback from the flight controller.

Mode-2 Operation

Connect: Buzzer beeps 3 times. Operation: Use UP ⬆️, DOWN ⬇️, LEFT ⬅️, RIGHT ➡️, ENTER buttons for menu navigation, scene switching, voltage calibration, and OSD reset.

Disconnect: Buzzer beeps 2 times.

Mode-1 Operation

Connect: Buzzer beeps 3 times. Operation: Use UP ⬆️, DOWN ⬇️, LEFT ⬅️, RIGHT ➡️, ENTER buttons for menu navigation, scene switching, voltage calibration, and OSD reset.

Disconnect: Buzzer beeps 2 times.

Note: If connected successfully, long-pressing the UP button enters the OSD menu, RIGHT switches presets, LEFT calibrates voltage, and DOWN resets OSD.

OSD Menu

Quick Settings

Access the OSD settings screen by long-pressing the UP button for three seconds.

Key Functions:

• Voltage Calibration: Long press LEFT ⬅️ for three seconds. Adjust voltage using UP ⬆️/DOWN ⬇️ when the text flashes.
• Reset OSD: Long press DOWN ⬇️ for six seconds to reset to default settings.
• Switch Presets: Long press RIGHT ➡️ for three seconds to cycle through camera presets.
• Clear ID: Use the 'CLR' option to clear the ID character. The camera allows for custom ID text entry (e.g., 1234567890ABCDEFGHIJKLMN OPQRSTUVWXYZ &:=./).
• Alarm: Configure low voltage warning values. The system can smartly judge the warning value or save a manually set value.
• Pilot/Timer/Voltage: Options to enable/disable and adjust position ('POS').
• Sharp View: Enhances image details but may increase noise.
• Widescreen: Stretches the image to a 16:9 aspect ratio, widening the edges without changing the image center.
• System: Set to NTSC.

Visual Description of OSD Menu: The menu displays options like QUICK SETTINGS, CLR, ALARM, PILOT, TIMER, VOLTAGE, SHARP VIEW, WIDESCREEN, SYSTEM, with corresponding values and settings.
