1.Product Introduction
1.1 Introduction
EH50 is a high-precision 3-axis gimbal integrated with a 50mm lens
640*480 IR thermal sensor. It supports IR thermal image switch, IR
color palette switch, photographing and video, target tracking and
thermal digital zoom. OSD can display angle, digital zoom times, status of
record and picture mode, tracking frame, also can select to turn off the OSD.
When the external GPS and time input, GPS coordinate and shooting time
can be saved in image file, OSD can display GPS and real-time as well. 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.
EH50 is widely used in UAV industries of public security, electric power,
fire fighting, zoom aerial photography and other industrial applications.

2.4 Install Mounting Part
(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.

2. Align the white dot (unlock icon) to the red triangle (below unlock
button), push the gimbal into the board 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 the board has been locked.
4. To unlock the gimbal, 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 board.

3.1 PWM Control
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.
3.1.1 PWM Connection Diagram (Connect pitch chan-
nel as example)
3. Signal Control
Above output mode is optional, HDMI and SDI output
cannot coexist at the same time. Please subject to
your actual product.
When using user interface software Viewlink for
network connection, the network of external device
(computer) should be the IP address: 192.168.2.2
(choose the last byte among 2~254, can not be 119
same as the gimbal), subnet mask: 255.255.255.0,
Default gateway: 192.168.2.1, and all firewalls of the
computer must be closed. Then enter the IP address
of the gimbal camera, Open Video, the video stream
can be outputted.

3.3 S.BUS Control
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):
Diagram of USB to TTL Cable:
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).
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.
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.

3.4 TCP control
For cameras with Ethernet output, the default IP address is:
192.168.2.119, control port: 2000. You can send the
corresponding protocol to realize TCP control after connecting.
The TCP control protocol is [Frame header: EB + command ID: 90 +
data body (serial port protocol) + Checksum (CS = body checksum,
checksum is calculated as a sum of all bytes of data body modulo
256)]. Or directly use UI Viewlink to control after TCP connection.
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.
