3.3高清图传连接HD VTX Connection

图传供电电压可通过跳线进行选择。出厂默认未短接跳线，图传端口输出 5V。手动将跳线切换至 BAT 后，图传端口输出电池电压。VTX power voltage is selectable via jumper. Factory default outputs 5V. Bridge to BAT for battery voltage output.

可通过图示焊盘切换 P4 接口的输出信号。使用前请确认当前焊盘状态与所接图传类型一致。Switch the P4 port output signal via the pads shown. Verify pad state matches your VTX type before use.

当飞控未连接 PIT OFF 时，可通过"VTX BEC OFF"模式控制图传端口供电。When PIT OFF is not connected, use "VTX BEC OFF" mode to control VTX port power.

当 VTX BEC OFF 模式未激活时，图传正常供电。When VTX BEC OFF is inactive, VTX powers normally.

当 VTX BEC OFF 模式激活时，图传端口停止供电。When VTX BEC OFF is active, VTX port power is cut.

请按图示连接 O4 Pro 图传。可使用配件 #22 的图传 35mm 6PIN 线材（见 1.2 包装配件概览）进行连接，也可直接使用 DJI 原装线材。Connect O4 Pro as shown. Use accessory #22 (35mm 6PIN cable, see 1.2) or original DJI cable.

请按图示连接 O4 Lite 图传。可使用配件编号 #22 的图传 35mm 6PIN 线材或直接使用 DJI 原装线材。出厂默认已完成相关设置，无需额外配置。Connect O4 Lite as shown. Use accessory #22 (35mm 6PIN cable) or original DJI cable. Factory defaults are pre-configured.

请按图示连接 Walksnail 高清图传。Connect Walksnail HD VTX as shown. 可使用配件编号 #23 的图传 60mm 4PIN 线材进行连接。该线材仅预装一端端子，另一端需根据图示线序，手动插入对应的 4PIN 胶壳后再连接图传。出厂默认已完成相关设置。Use accessory #23 (60mm 4PIN cable). One end is pre-terminated; manually insert the other end into the 4PIN shell per the pinout diagram. Factory defaults are pre-configured.

（1）接线图（以Freestyle V2 VTX 为例）(1) Wiring Diagram (Example: Freestyle V2 VTX)

HDZero Freestyle V2 需使用图传自带排线进行连接。由于 HDZero 默认线序与 DJI 不同，接线前请先按图示重新整理端子顺序，再插入接口。HDZero Freestyle V2 uses its own cable. Since HDZero pinout differs from DJI, re-arrange terminal order per the diagram before connecting.

（2）Betaflight 设置(2) Betaflight Settings

出厂默认已完成相关设置，无需额外配置。Factory defaults are pre-configured, no extra setup needed.

（3）注意事项(3) Notes

3.4模拟图传连接Analog VTX Connection

使用模拟图传时，需通过跳线将图传模式切换为模拟图传模式。When using analog VTX, switch mode to analog via the jumper pads.

连接 4PIN 模拟图传时，可使用配件编号 #23 的图传 60mm 4PIN 线材。该线材仅预装一端端子，另一端需根据图示线序，手动插入配件编号 #11 的 4PIN 胶壳后再连接图传。For 4PIN analog VTX, use accessory #23 (60mm 4PIN cable). One end is pre-terminated; insert the other end into the accessory #11 4PIN shell per the pinout.

请在 Betaflight CLI 中输入以下命令并保存：Enter the following commands in Betaflight CLI and save:

随后在 Ports 页签中，将 UART2 设置为对应的图传协议。若使用 IRC Tramp 或 TBS SmartAudio，请以图传说明书为准。Then in Ports tab, set UART2 to the appropriate VTX protocol. For IRC Tramp or TBS SmartAudio, refer to VTX documentation.

连接非 4PIN 模拟图传时，请根据图示线序，手动插入配件编号 #5 的 5PIN 胶壳或配件编号 #12 的 6PIN 胶壳后再连接设备。For non-4PIN analog VTX, manually insert into accessory #5 (5PIN shell) or #12 (6PIN shell) per the pinout.

Betaflight 设置同 3.4.2。Betaflight settings same as 3.4.2.

3.5模拟摄像头连接Analog Camera Connection

模拟摄像头可使用配件编号 #24 或 #25 的模拟摄像头排线进行连接。请根据机架内摄像头与飞控之间的实际距离选择合适长度的线材。接线前请先核对摄像头端与飞控端的线序。Connect analog camera using accessory #24 or #25 camera cables. Choose appropriate length based on frame layout. Verify pinout before connecting.

3.6接收机连接Receiver Connection

出厂默认已启用内置 ELRS 接收机，无需额外配置。使用前请先将配件编号 #2 的 ELRS 2.4G 接收机天线正确安装到飞控天线座上，再进行通电与对频操作。Built-in ELRS receiver is enabled by default. Install accessory #2 (ELRS 2.4G antenna) onto the FC antenna connector before powering on.

（1）非 SBUS 接收机：需要短接下图所示焊盘，以启用外置接收机。(1) Non-SBUS receiver: Short the pads shown below to enable external receiver.

（2）SBUS 接收机：需要同时短接"启用外置接收机"焊盘和"启用 SBUS"焊盘。(2) SBUS receiver: Short both "Enable External RX" and "Enable SBUS" pads.

SBUS 接收机的信号线需要连接到图传排线座旁边的 SBUS 焊盘上（UART4）。若使用Dji天空端内置接收机，同样需要短接"启用外置接收机"焊盘和"启用 SBUS"焊盘。SBUS signal wire connects to the SBUS pad near the VTX connector (UART4). If using DJI air unit built-in receiver, also short both "Enable External RX" and "Enable SBUS" pads.

3.7GPS 连接GPS Connection

GPS 可使用配件编号 #26 的 GPS 120mm 4PIN 线材（见 1.2 包装配件概览）进行连接。该线材仅预装一端胶壳，另一端胶壳请根据 GPS 实际线序手动装配。Connect GPS using accessory #26 (GPS 120mm 4PIN cable, see 1.2). One end is pre-terminated; manually wire the other end per your GPS pinout.

下图以 BZ181 为例。Example below using BZ181.

若 GPS 模块带有罗盘，可使用配件编号 #26 的 GPS 120mm 双头端子线连接 SDA 与 SCL；下图以 BZ251 为例。If GPS module has compass, use accessory #26 cable to connect SDA and SCL; example below using BZ251.

GPS 连接至飞控的 UART7 端口，出厂默认已完成端口设置。只需要在 GPS 选项卡中，打开 GPS 即可使用。GPS connects to UART7. Port settings are pre-configured. Just enable GPS in the GPS tab.
