Frequently Asked Questions

This section collects common questions and answers about product usage, functions, and troubleshooting.
About Power Supply
1. Q: What’s the power supply standard for Viewpro gimbal cameras?
Answer: The power supply range of Viewpro gimbal is 3S~6S (12V~24V), except the special customized version (without the CONN board – main board of control box). Excessive high voltage and high voltage ignition when the power supply is not connected to the voltage regulator module will cause the gimbal burned out, and there will be no response when it is powered on. 
2. Q: Why there is no response and cannot work after the gimbal is powered on?
Answer: Use a DC stabilized power supply to check if the current is 0 or not. 0mah means the power line is an open circuit, check whether the two ends of the line are well plugged in. If there is no DC power supply, use the voltage grade of the multimeter to test the voltage of the two power lines to the gimbal. If the voltage of the point is 0V, it means that the power line is an open circuit. Check whether the two ends of the line are well plugged in. 
3. Q: Why camera has no video output after home position?

Case 1: Gimbal power supply is not enough

Answer: Make sure power supply is 3S~6S (12V~24V), make sure the power cable can support 2A electric current.

Case 2: Gimbal internal power problem

Answer: The internal power cable of the gimbal is pressed.

About Series Port TTL Connection
1. Q: How to test the provided USB to TTL cable?

Answer:

(1) The PC needs to install the serial port driver. After connecting USB end to the PC, check the “Device Manager”-”Port”-”USB-SERIAL CH340 (COM x)” to confirm the correct COM port.

(2) If there is no “USB-SERIAL” icon, please install the serial port TTL driver.

(3) After installing the driver, connect the wire TX and RX of the cable together, use the serial port assistant to send data to check whether the serial port environment is normal or not. If it can receive what it just sent to itself, means the cable is normal. 

2. Q: How to solve the problems that serial port does not work?

Case 1: Use the provided USB to TTL cable, can control gimbal, but no feedback

Answer: Re-connect both ends of the cable and try again. If there is still no feedback, test the TX-RX of the cable itself (Re. 2.1 How to test the provided USB to TTL cable?). Check if the sent and received data is consistent or not to confirm if the cable is good or not. If the cable is normal, restart the gimbal, and try again. If it is still abnormal, it may be the wiring is an open circuit inside the gimbal. For standard version gimbal, re-connect the 15pin cable on control box. For Viewport version, re-connect the serial port wiring terminal and re-connect the Viewport.

Case 2: Standard version: The yellow jumper cap on the CONN board is off, can not control the gimbal (pitch and yaw), but the camera control (zoom and record) is normal.

A: Need to make short-circuit at the jumper cap position.

Case 3: Standard version: The gimbal is under S.Bus mode, meantime the serial port cannot communicate.

Answer: Follow the related instruction to recover serial port control.

Case 4: Gimbal can not communicate via TCP/TTL.

Answer: Test the gimbal by PWM control. If the camera cannot be controlled, and the program light on the CONN board does not flash, probably the CONN hardware is damaged, return to factory for repair.

Case 5: Standard version: Can control gimbal but not the camera

Answer: 1) Check if the software of the gimbal is match or not, e.g. the cameras (Z40K, Z-Fusion pro, Q30XIR) have 2 baud rates, need to pay attention to this point.

2) Check if the communication from camera RX to CONN board TX is OK or not. If not OK, need to repair.

3) If the communication from camera RX to CONN TX is OK, switch a CONN board of same model (if it’s available) to test, or remove the diode D20 on CONN board and test again.

4) If still not works after all above operations, probably the camera module is broken. 

About Gimbal Problem
1. Q: Gimbal behave abnormal when it’s powered on

Case 1: The gimbal roll axis hits the yaw motor and rolls randomly or no respond after powering on, or rotate randomly in all 3axis.

Answer:

(1) Connect to serial port, make sure it is well connected

(2) While turning on the camera, continuously send command “3E 1B 00 1B 00 00″ to turn off the motors, keep clicking (or set sending interval 500ms) until motor stop moving.

(3) Send command “3E 45 01 46 0B 0B 3E 1B 00 1B 00 00″, and wait for the automatic calibration of the gimbal to complete

(4) After calibration, adjust the horizontal position of the camera lens align to the installation arrow (you can move manually it to the desired position and wait for 2S), send command “3E 1A 00 1A 00 00″ to save this position (it’s also the home position and the position after power-on self-checking)

Case 2: After powering on, the gimbal pans randomly.

Answer:

(1) The image and data transmitter antenna on the drone interferes with the magnetic encoder of the gimbal. Turn off the transmitter to eliminate the interference and then judge accordingly. If the phenomenon disappears, adjust the position (preferably more 35cm away) or direction (not facing the direction of the gimbal) of the antenna.

(2) Eliminate the interference of the unstable power supply by supplying power to the gimbal independently, or adjusting the voltage (try both 3S and 6S power supply).

(3) Update the program of the CONN board/DJI version software/Viewport controlling software to solve the problem that the serial port is interfered when starting up and incorrectly sent commands. (Solution only for new gimbals that rotate randomly and repeat same issue even temporarily work normal after sending command to calibrate.)

(4) If all the above methods have been tried, the gimbal still rotates after the drone is powered on, indicating that the gimbal is subjected to electromagnetic interference, and the internal data got error, need to send it back to factory for anti-interference processing.

(5) Special case: gimbal rotates after working for a while with CAN, motors are burning hot,

Case 3: After powering on, the gimbal is normal. After a period of time, irregularly jerks or motionless and have a chirping sound

A: Caused by IIC error (The main board controlling chip is broken).

Case 4: Turn off the image & data link and turn on again, the gimbal motor rotates abnormally, and have a chirping sound

Answer: Have you ever disassembled or assembled the damping plate? This operation may cause this problem

Case 5: The gimbal motors not moves but has chirping sound after powering on.

Answer: Send: 3E 3d 00 3d 00 00 to query for the gimbal angle feedback, if all value of IMU are 0, means gimbal IMU abnormal. Check if the 5V output of gimbal control box is normal or not. If normal, check if the internal wiring of IMU is normal or not, or if the connector loose or not. If gimbal is IP only version, check if the slip ring is OK.

2. Q: What feedback can I get from gimbal serial port?

Answer: Manual feedback: angle value of each axis, zoom times of the camera, and infrequently used data (tracking offset, rangefinder distance, target position)

Automatic feedback: angle value of each axis and angular velocity (set the feedback mode, turn on the automatic feedback)

The system default automatic feedback structure: (not set the feedback mode)

3. Q: How to set/query gimbal follow/disable follow mode?

Answer: 

follow_yaw_disable (mode not to follow the pan of the drone): 3E 1F 06 25 01 1F 00 00 00 00 20

follow_yaw_enable (mode to follow the pan of the drone): 3E 1F 06 25 01 1F 01 00 00 00 21

query_follow_state (query current mode): 3E 40 02 42 01 1F 20

save gimbal settings (save, the mode of the next startup is the same as the save mode): 3E 20 00 20 00 00

Obtained from the query when starting up: 3E 1F 06 25 01 1F FF FF FF FF 1C (For accurate query, please send the mode command first) 

4. Q: How to solve slight drift during disable follow mode or after stop?
Answer: Send command to stop: FF 01 0F 10 00 04 04 00 00 00 00 00 00 00 00 00 00 00 00 00 08 
5. Q: What phenomenons of the gimbal is normal?

Case 1: Gimbal tracking, after exceeding the limit angle upwards, the gimbal will move downwards. This is normal.

Case 2: Gimbal (old shipment) under speed mode, it cannot be controlled after passing the YAW axis limit.

Case 3: If the gimbal (old shipment) is mounted upside-down and pitch down to the limit, it will cause the lens to face upwards. 

6. Other infrequently used commands (not common)

1) How gimbal enter the scan mode?

Answer:  Add script to gimbal tuning and run the script

Enter scan mode: 3E 45 01 46 1B 1B

Exit scan mode: 3E 45 01 46 1A 1A

2) Gimbal receive stop feedback

Answer: send command “AA 55 20 10 FF”, then turn on to enable.

Send: FF 01 0F 10 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

Case 3Gimbal yaw does not follow or follow is too much sensitive.

Answer:

(1) Use the Mode channel of the remote control to switch quickly 4 times in a row (three-gear switch: middle gear –> high gear –> medium gear –> high gear –> medium gear –> high gear - -> Middle gear –> High gear) to see if it follows or not.

(2) Use Viewlink control software, serial port control, turn on “Enable Follow” to see if it follows or not.

(3) Use the command to query the parameters, after getting the feedback parameters, modify the corresponding parameters. Save the setting by sending: 3E 20 00 20 00.

8. Q: How to deal with gimbal jerk?

Answer:

(1) Check the stability of the gimbal when powered off, ensure the balance of each axis.

(2) Check the mounting method, the type of damping balls, whether they are too less or too many, whether they are aged, and whether the damping plate has been modified.

(3) Check whether the external wiring of the gimbal is pulled tightly to the gimbal.

(4) Modify the gimbal PID parameters. 

9. Q: Gimbal control is abnormal, can not control randomly after power on.

Case 1: Some frame header “AA…” / ”55 AA…” / “7E 7E…” not in gimbal protocol file are sent which caused analysis error and gimbal no respond.

Answer: Change the frame header of non gimbal protocol, could not be similar.

Case 2: Some invalid data are sent via serial port to the gimbal cause the gimbal serial port no respond.

Answer: Modify software: Reduce serial port voltage when power on, or delay the startup of the serial port. 

About IR Thermal Camera / Tracker
1. Q: Thermometry IR thermal camera version, the image is red. How to solve?

It is a temperature alarm, which can be eliminated

Case 1: Use Viewlink software, PWM, S.BUS control

Answer:

(1) Connect serial port, make sure it is well connected.

(2) Send commands “AA 55 0A 96 FF” and “AA 55 0B 43 FF”, and the received feedback commands are same as sent.

Case 2: Use protocol control

Answer: Picture-in-picture switching/color palette switching command, which needs to set the temperature alarm value; the 9th to 12th byte in the 7E command is the temperature measurement alarm setting bytes, float single-precision floating-point 32-bit (4 bytes, big- endian) is converted into a decimal temperature value, the factory default value is 300° (float: 43 96 00 00)

0×38: Medium template + large template

Example: You can send AA 55 1E 28 FF to set the track size to a medium template

8. Q: How does the tracker output offset?

Answer:

Send command:   AA 55 20 02 FF —— output offset

AA 55 20 00 FF —— don’t output offset

Output format: BB 01 XL XH YLYH 02 CS (CS: sum of all bytes modulo 256)

For example: BB 01 2A 01 80 FE 42 A7

X-axis offset 0x012A–> 298  Y-axis offset 0xFE80–> -384 (relative to the center point deviation pixel point: right positive, left negative, bottom positive, above negative)

When sending stop tracking command, it will feedback: BB 01 00 00 00 00 20 DC

Viewlink Protocol: the center point is 0, the center coordinate of offset (0,0)

Subtract (960, 540) from the pixel coordinates of the locked targets

About ViewLink Problem
1. Viewlink installation error: Can’t find xxxx.dll, the code cannot be executed.
Answer: Download xxxx.dll document,put into ”C:\Windows\System32”. 
2. Viewlink network cannot open video stream?

Case 1: The computer Ethernet connection shows network connection error

Answer: The gimbal Ethrenet interface is not connected or connection is not well, reconnect it. If it’s still abnormal, use a multimeter to measure the resistance of 4 Ethernet wires of the gimbal. Measure the resistance of any each 2 wires, between 3-4Ω is normal, if not, the gimbal’s failure. 

Case 2: The gimbal IP address can ping well, and the Viewlink TCP control can be connected

Answer:

A. Reconfigure the encode settings with the Camera Configuration Tool (download from Viewpro website) according to factory default settings, and restart the gimbal. DHCP needs to be turned off when output video by RTSP.

B. Viewlink can control gimbal via TCP, but can’t output video stream. And video stream works well in other playback software, then turn off all the firewalls of your computer. 

Case 3: The computer Ethernet connection shows that the network connection is normal, but the gimbal IP address cannot ping normally (If you ever changed the IP)

Answer: Use a USB to TTL cable, connect the computer to the gimbal serial port, open Viewlink -> “settings” -> “extended commands”, and send: “7E 7E 44 00 00 87 C0 A8 02 77 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 A8 “, restore the factory default IP (rtsp://192.168.2.119/554), Restart the gimbal and connect again. 

Case 4: Gimbal IP address cannot ping (and Case 2 B processing can not help, because the coding parameters are incorrect)

Answer: Use the TF card to upgrade the IP firmware to recover the IP and encoding settings. Restart after the upgrade. 

3. Q: Viewlink can output video stream but can control the payload?

Case 1: Both serial port (TTL) and TCP control cannot be connected, video stream is normal (Viewport version)

Answer: Press on the Reset button on the control box of Viewport and hold until upgrade finished. Power on the gimbal. Upgrade on Viewlink: “Settings” -> “firmware upgrade” -> “upgrade file” -> “start”, re-burn the program, restart the gimbal and try the control again.

Case 2: The serial port is normal, but TCP can not connect, video stream is normal

Answer:

(1) The computer has turned on VPN or firewalls. Please turn of VPN and firewalls.

(2) The serial port TX of camera is broken. Check OSD zoom changes or not or tracking works or not by serial port control. If OSD no change when zoom or could not start tracking means TX of camera is broken.

(3) Some gimbals not support TCP control. Please refer to the product specification or manual for details. 

4. Q: Viewlink serial port upgrades firmware, but failed?

Case 1: Use Viewpro USB to TTL cable, the software can control gimbal, but upgrade timeout

Answer: USB to TTL cable may be not well connected, reconnect both ends.

Case 2: The upgrade is interrupted during the upgrade process, and the serial port can no longer be connected.

Answer: Use the old method to upgrade by SecureCRT 

5. The local recorded video of Viewlink cannot be opened?
Answer: Upgrade IP firmware to the latest version, use the latest version Viewlink.

About GPS / Fight Control Integration
1. Q: How to access external GPS information to the gimbal?

Case 1: The gimbal is directly connected to the GPS module

Answer: 1) Change the baud rate of the GPS module to 115200, GPS has GGA or RMC information output under the NEMA-0183 protocol. 2) Cross connect TX and RX and sent the data to gimbal serial port.

Case 2: Open source flight control output GPS information to gimbal GPS

Answer: Connecting with GPS module the flight control will send GPS data GLOBAL_POSITION_INT ( #33 ) to the gimbal serial port through FC telem port (setting: 115200, Mavlink1);

Case 3: Need development: Send GPS data to the gimbal serial port through the serial port position analysis protocol or the M packet format in the Viewlink protocol.

2. Q: How to display external GPS information on the gimbal camera image and photo attributes / exif?

Solution 1: Set by Viewlink: Connect the gimbal to Viewlink by serial port or TCP, on Viewlink: ”Settings” -> “OSD Configuration” -> Turn onn”GPS” and “GPS Input” -> “Save”

Solution 2: Set serial commands via serial port assistant: ”AA 55 05 00 FF” (Dispaly GPS on OSD), “AA 55 07 B7 FF” (OSD save)

3. Q: Test GPS display by sending commands

Answer: Send any of below commands to verify whether the GPS information can be displayed or not.

(1) {7E 7E 44 80 00 83 37 E4 07 09 10 10 05 31 00 00 00 00 00 00 00 00 00 00 00 00 00 24 83 90 02 72 DA 44 40 7F 82 CB E7 40 DC 5E 40 00 00 48 42 C4}

4. Q: How to change GPS time zone?

Answer: Send serial command “AA 55 04 08 FF”, “08″ represents the East 8 zone, East is positive and West is negative. Send commands to change zone according to the location. This command adapt to the case that GPS or flight control data is connected, and cannot be used to the protocol M package. Correct time information need to be provided.

F9 FB E3 07 0A 0B 0C 00 00 15 F0 6C 3C B7 FD 84 3C 62 C9 91 40 0E 3F 57 17 59 B4 F7 45 00 00 00 00 20 (2019.10.11  12:00:00)

Note:

Set time zone protocol update:

AA 55 04 HH FF AA 55 34 MM FF  HH is signed integer, is the hour of the time zone, and MM is a minute of the time zone, also a signed integer.

For example, sett to -5:30: AA 55 04 FB FF AA 55 34 E2 FF

5. Q: T series, not connect with GPS module, send according to location protocol or M package, can write time into exif when take photos.

Answer: Keep sending command with time/GPS input, Viewlink protocol command “55 AA DC 11 30 00 01 00 3F FC 00 00 00 00 04 D0 00 00 00 37″ to take photos with time or GPS attributes.

For example:

Send:F9 FB E3 07 0A 0B 0C 0D 13 15 F0 6C 3C B7 FD 84 3C 62 C9 91 40 0E 3F 57 17 59 B4 F7 45 00 00 00 00 40

6. Q: Which models support geo-tagging (write GPS and time into photo exif)?
Answer: Z40K, Z40KT/Q40TIR/Z40TIR/Q20T and other T series gimbals.
7. Q: How to set up the open source flight control to solve the roll axis tilting problem of gimbal when fixed wing turns too fast?

Answer:

Connect the gimbal serial port to a TELEM of a open source flight control (e.g.: Pixhawk) to compensate for horizon drift during high dynamic flight.

FC TELEM port parameter settings: baud rate 115200, MAvlink1.

Set the parameters in ArduPilot:

•SERIALx_BAUD = 115

•SERIALx_PROTOCOL = 1

Where “x” is the port number. The value is 1 (Mavlink).

In addition, set the following message rates for this port:

•SRx_EXTRA1 = 10

•SRx_POSITION = 10

Note: All other SRx_xx parameters should be set to 0 to prevent unnecessary data from overloading the channel.

8. Q: Problems encountered when using the flight control Mavlink serial port and S.bus control

Answer:

(1) Roll axis tilt: Turn off SR1_EXRA3 data

(2) Big delay: Change SRx_RC_CHAN to 20HZ

(3) No respond to FC Mavlink serial port control: The program is older than 20210429. Update.

9. Q: How to control gimbal by SBUS out of flight control?

Case 1: Pixhawk, Pixkack/ V3 FC connect to RSSI, V5 series FC connect to SBUS_out pin

Answer: BRD_SBUS_OUT  set to 1 (50hz)

SERVO_SBUS_OUT  default as 50

BRD_SAFETYENABLE  change default 1 to 0 , or turn on safety button.

Case 2: X7 series FC do not have independent SBUS_OUT interface, output SBUS signal by serial port directly

Answer: SERIAL4_PROTOCOL  set to 15

SERIAL4_OPTIONS  set to 2

After the above settings, TX pin of FC uart4 interface will output SBUS signal. Similarly, other serial port can also be set as SBUS output.

Control method:

Servo8 set as 56, the channel 6 of the RC controls the channel 8 output by FC, which is to control the channel 8 output by SBUS.
