Mounting
Mounting the Payload to the X-Port Gimbal
Payload Interface Mounting
The connector used to connect the gimbal and payload is a 20-pin board-to-wire connector from ACES 
Electronics Co., Ltd. The model is S-50420-020HKH0-001.
 Make sure to reserve a hole on the position where the payload is mounted on the gimbal pitch 
primary arm so that the connector end and the cable (the length is about 100 mm) can come 
out.
 DO NOT plug in or unplug the payload from the connector when powered on.
Payload Mounting Steps
Follow below steps to mount the payload to the gimbal.
1.  Insert the 20-pin connector’s male end to the gimbal mainboard’s female end on the pitch primary 
arm, make sure to keep the payload and the gimbal facing the front, while the microSD card slot 
points to the gimbal rear. Then use four M2 screws to install the payload onto the gimbal, with some 
thread glue applied on the screws to ensure secure installation.
2.  Gently open the pitch secondary arm to put the secondary arm sleeve between the gimbal and 
payload. Apply an appropriate amount of 243 thread glue to the thread of the secondary arm 
mounting screw, tighten the screw from the other side of the secondary arm, and nally attach the 
secondary arm plug and ensure that it is pressed to the end.
