The external illuminator is connected to the TTL interface (T1 to T4) or LED interface (F1 to F4) of a camera. Therefore, a camera can connect to a maximum
of eight external illuminators. The connection mode varies depending on the signal control cable type of the illuminator.
外置补光灯通过摄像机的 TTL 接口（T1 至 T4，共 4 个接口）或 LED 接口（F1 至 F4，共 4 对接口）与摄像机相连，因此，摄像机一共可连接 8 个外置补光灯。根据补
光灯的信号控制线类别的不同（电平量线或者开关量线），具体的连接方式有两种，参考如下：
1, The positive level output cable of the illuminator is connected to the TTL interface (T1, T2, T3, or T4) of the camera. The negative level output cable or
ground cable (If multiple illuminators are connected, multiple negative level output cables or ground cables need to be connected in parallel first.) to the
GND interface of the camera (T1 and T2 share one GND interface, and T3 and T4 share the other GND interface).
补光灯的电平量正极线连接摄像机的 TTL 接口（T1、T2、T3 或 T4 接口），相应的负极线或接地线（若接多个补光灯，则多根负极线 / 接地线先并联），接至对应的
摄像机 GND 接口（T1 和 T2 共用一个 GND 接口，T3 和 T4 共用另一个 GND 接口）。
2, The positive Boolean value cable of the illuminator is connected to the positive LED interface (F1+, F2+, F3+, or F4+) of the camera. The negative
Boolean value cable or ground cable is connected to the negative LED interface (F1-, F2-, F3-, or F4-) of the camera.
补光灯的开关量正极线连接摄像机的 LED 正极接口（F1+、F2+、F3+ 或 F4+），相应的负极线或接地线分别连接至对应的 LED 负极接口（F1-、F2-、F3- 或 F4-
）。
External Strobe Light Connection Description/ 外置补光灯接线说明
• If the signal control cable of the illuminator is not clearly identified as a level output or a Boolean value cable, check the illuminator instructions or
consult the illuminator supplier to confirm the signal control cable type.
若补光灯的信号控制线无明确标识是电平量线还是开关量线，请查看补光灯的说明书或咨询补光灯供应商，确认其信号控制线的类别。
• The TTL interface of Huawei ITS cameras can identify only level ranging from 0 V to 5 V. If the voltage of the illuminator signal control cable is
higher than 5 V, only the second connection method can be used.
华为ITS摄像机的TTL接口只能识别0~5V的电平量，若补光灯控制线电压高于5V，则接线方式只能使用第二种，即控制线连接至摄像机LED接口的连接方式。
