Important Note
Warning
Q20K is a high-precision 3-axis gimbal integrated with a 20x optical
zoom 4K SONY camera. It supports visible optical zoom, photo-
graphing. It features aluminum alloy housing and anti-interference.
The 3 axis gimbal can achieve stabilization in yaw, roll and pitch. The
integrated design of damping system and gimbal can greatly reduce
mechanical vibration.
Q20K is widely used in UAV industries of public security, zoom aerial
photography and real time broadcasting.
Congratulations on purchasing your new Viewpro product. Please
read this entire document carefully. Failure to read or follow instruc-
tions and warnings in this document may result in damage to your
Viewpro product. Disassemble the gimbal camera by user is not
permitted, as which may cause the camera does not work normally.
Viewpro accepts no liability for damage, injury or any legal responsi-
bility incurred directly or indirectly from the use of this project. The
user shall observe safe and lawful practices including, but no limited
to, those set forth in the manual.

2.4 Install Mounting Part
8.
(1) Find out the arrow on the gimbal which indicating the yaw
heading of the payload (i.e. the lens direction when the camera
power on), and synchronize with the direction specified by the UAV.
(2) Fix one end of the copper cylinder on the screw hole of lower
damping board, and use M3 screw to fasten it.
(3) According to the provided screw hole dimension you can make
suitable mounting holes on the UAV mounting board, and fixes the
other end of the copper cylinder on the mounting board of the UAV
(Viewport version is the same).

2.5 Viewport Release Instruction
9.
1. Make sure the two white stripes indicated in above picture are
aligned with each other. (If the stripes are not aligned to each other,
please pinch the connector part and turn it to left manually)
×

10.
2. Align the white dot (unlock icon) to the red triangle (below unlock
button), push the gimbal into the Viewport completely and then
rotate the gimbal camera anticlockwise.
3. When you hear "click" sound (when red dot is aligned to the red
triangle) means the gimbal camera and Viewport has been locked.
4. To unlock the Viewport, you need to press on unlock button and
rotate the gimbal camera clockwise till the white dot align to the red
triangle. Then pull the gimbal out from the Viewport.

2.7 Image Output Interface
3.1 PWM Control
11.
Control the gimbal camera functions by the multiplex pulse width
modulation signal outputted by PWM channel of the remote control
receiver. The camera needs up to 6 control channels of PWM (to
expand tracking function use up to 7 PWM channels). You can choose
needed functions according to actual usage to reduce the required
number of PWM channels.

frame)
3.4) Operate 4 times continuously and quickly, from position 2 - 3 - 2

by frame)
4) Zoom (PWM Zoom channel in to control Zoom. Joystick, rotary
knob or 3-gear switch on remote control are optional. 3-gear switch as
example.)

Connect the camera to the upper computer by USB to TTL cable
(Adopt connection method of TX to RX, RX to TX, GNG to GND at
Dupont ends of the provided USB to TTL cable, connect to the
specified TTL of the gimbal, and the USB end of the cable connect to
computer).
Control the gimbal camera functions by one combining signals.
Connect the external S.Bus to S.Bus port on the control box, and the
external S.bus signal GND connect to the GND interface of the control
box.
Wiring Diagram (Take Futaba remote control for example):
Install Viewlink control software to test the functions directly. Users
may choose to develop their own software, please contact technical
support for TTL control protocol file.
ViewLink is a user interface developed by Viewpro for Viewpro gimbal
cameras, you can download it from Viewpro website (www.viewpro-
tech.com) or ask distributors for installation package.
Connect serial port of gimbal to pins, DO NOT connect
with power supply.
The default baud rate of serial port is 115200, which
can be changed according to the docking equipment.

S.Bus control mode: default S.Bus signal channel 9-15 to control
gimbal camera functions (the function of channel is consistent with
corresponding channel in PWM function description)
TTL control and S.bus control cannot coexist at the
same time for standard version. The defualt control is
TTL if no requirement. The user can set to S.bus control
if needed (please contact with our technical support for
the setting instruction.)
User can set the channels by setting serial command
according to the actual requirement. The S.Bus channel
position can be arranged in any sequence within
channel 1-15 to connect with the flight controller or
remote control.
