2.Make sure the third party videolink is double-way transmission, otherwise, otherwise you may not
be able to control the pod
3.Make sure the pod and videolink wire sequence are correct: TX+ ---- TX+, TX - ---TX -,RX+ ----- RX+, RX - ---- RX -.

PodBrief functional description, supported pod type, etc.
The pod system is divided into two levels: professional load, lightweight load. Adapt to different levelsof multi-rotor drones or unmanned straight-lifts. Different levels of load, shock absorption quick-detachmounting plate can not be replaced with each other, but GCS software and the data chain is unified.

IDU/IDUS
IDU/IDUS is a module which integrated shock-absorbing, quick-disassembly, and gateway module, and it isan indispensable part of the pod series.
Professional class load using IDUS, Professional class loads include: X30, X30T, X30GT, D640,
D640C,D640A, D640AC.
Lightweight load using IDU. The lightweight loads include: argus, a2000.
The same level of pod can share the shock absorber and quick-deach gateway module.

Installation (with notes)
Hardware Installation
A. IDU, IDUS installed to drone.
Please install the IDU, IDUS to the proper position of the UAV to ensure that the installation position is stable,
firm and no sloshing.
Ensure that there is no occlusion and interference in the range of pod activity.
Make sure the IDU module is dry without blocking in the shock absorption range. Please keep certain
activity space redundancy for power cord, network cable ,7P transfer wiring,
Ensure locking between pod and IDU, buckle well and prevent shedding during flight.
Do not plug the pod when the aircraft is electrified.
Please check the damping shock absorber regularly for breakage and leakage. In case of breakage, please
replace in time. Do not disassemble the damper ball frequently, or touch the ball with sharp objects to avoid
breakage.
B. Datalink sky-end installation, antenna installation
Please install the datalink in the appropriate position of the aircraft and ensure good ventilation and heatdissipation.
Make sure the cable (4P wire, serial line) is firmly connected, no loosening, no breakage of the cable.
Please keep a certain activity space redundancy for power cord, network cable, serial port.
C. IDU and videolink sky-end Power Supply
IDU / IDUS R2S (with sky end, ground end) supports 12-25v power supply.

Installation and setup methods of third-party videolink
A. Modify IP of Pod and IDU (segment to meet videolink requirements)
Pod segment modification, take “change 42 segment to 1 segment” as an example:
1、pod electrified, and connected the pod to the computer through the wire, the pod works normally after
about 15 seconds, the computer recognizes the camera network.
2、TCPIPV4 settings, as shown below, are saved after confirmation

192 168 42

Foxtech EH640 30x Optical Zoom IR Thermal Camera User Manual
Tablet (or touch screen) mouse, virtual button operation:
1. Yaw, Pitch adjustment
Hold down the left button of the mouse (slides on the screen if using the touch screen) and move up anddown in the interface. the lens move following the mouse position. Loosen the mouse left button, the lens
stops moving and stays in the current position.
2. Point zoom
Double-click the mouse left button (double-click if it is the touch screen), the double-click position move tothe center of the screen and zoom in 2 times, accumulating to the maximum focal segment.
Sliding mouse wheel, can also control the zoom in and out of the lens.
Click the mouse right button (long press for 3 second on the touch-screen ), and the screen automatically
returns to the 1X focus section.
3. Focus
Camera default auto-focus mode, when the screen background is complex, can use the virtual keys "focus
plus" and "focus-" for manual focus.
If the screen blurred for a long time, you can click on the "focus A" virtual button, actively focus.
4. Calibration
If the user does not use the topgun series flight control, not connect digital link, CAN transfer. When
operating in an environment with large pre- and post-flight temperature differences (e.g., winter aircraft
moving from indoors to outside). Calibration is recommended before flight to reduce heading drift.
5. Auto tracking
Click on the target tracking button, then the mouse moves to the real-time screen display area, press andhold the left mouse button, drag to select the desired tracking target area, release the left mouse button willappear a box. the pod will automatically track the target inside the box.
6. Calibration steps
pod initialization is complete, into normal working state. Clicking on the calibration virtual button (setting →calibration), the pod will enter the calibration state (the gimbal motor does not work at this time) ensure thatthe aircraft and the gimbal is in a static state (the gimbal does not need to keep horizontal), after waiting for
5 to 10 seconds, the pod is re-initialized to complete the calibration.
Game Joystick Operation:
GCS supports USB game joystick control pods (take Northlink Bat DFBTP-2126F as an example)

No Image
Hardware checking:pod power supply is normal, pod and idu module are properly connected. The pod works properly.
Datalink (sky end, ground end) power supply is normal. The datalink sky end is properly connected to theIDU module, and the connection wire is not broken. The datalink ground end and the computer is connected
normally, the network wire does not have the damage to break the circuit.
Software setup check:
Make sure the computer network is set correctly and the computer turns off the wifi when connecting thedatalink. The computer is not connected to any network other than the data link.
Software network IP address is incorrect :(when the gimbal, camera IP address changes, need tosynchronously modify this software IP)
Open GCS software → network settings
Modify the IP address.
