1.1 Introduction
1.Product Introduction
1.
Important NoteWarning
Z-A7 is a pinpoint-precision professional 3-axis gimbal which
features high stability and low power consumption. It's designed
specially for SONY Interchangeable Lens digital Cameras, can be
integrate with SONY a7R ll / III / IV camera（FE 24-105mm f/4 G
OSS、E 55~210mm) for powering the cameras, fulfill functions of
record, shutter, zoom, camera on/off etc. Z-A7 can take 90°down-
ward ortho image and video as well. The HDMI cable is led to the top
of gimbal from bottom inside which makes the gimbal compact. The
speed of Z-A7 gimbal is adjustable, LOW speed in tele end, the
control will be more accurate; Fast speed in wide end, which makes
the gimbal control sensitive and quick. Also the one-key to center
function will allow the gimbal return to initial position automatically
and rapidly.
Z-A7 is widely used in UAV industries of electrical industry,
transmission towers, electric substations, zoom aerial photography
and other industrial applications.

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).

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.

2.6 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.

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 default 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.
