There may be several situations in the cloud station failure: the PTZ cannot be controlled, the decoder cannot be controlled, some functions cannot be realized, and the signal indicator of the code converter does not work. 
Code turn signal does not flash <br> Software settings (the light does not flash, mainly because the code converter does not work, first solve the problem from the software settings):
1. Decoder settings in the software (decoder protocol, COM port, baud rate, parity bit, data bit, stop bit).
2. Replace a COM port (check if the COM port is damaged).
3, hardware, such as the above settings, still can not be used normally, open the nine-pin to 25-pin converter interface. Check if the wiring is 2-2, 3-3, 5-7. If it is correct, check if the code converter power supply is normal (multiple meter can be used for voltage and current test (9V, 500MA)), no problem can be judged that the code converter has damage
Unable to control decoder <br> No relay sound in decoder:
1. Check if the decoder is powered.
2. Check if the code converter has pulled out the output 485 signal.
3. Check if the decoder protocol is set correctly.
4. Check if the baud rate setting matches the decoder (check that the address code setting is consistent with the selected camera (see the decoder manual for the detailed address code drawing table).
5, check the decoder and code converter wiring is wrong (1-485A, 2-B; some decoders are 1-485B, 2-A)
6. Check if the decoder works normally (the old decoder is powered off after one minute of power failure, whether there is self-test sound; when the software controls the pan/tilt, there will be voltage change between the port of UP, DOWN, AUTO and other ports of the decoder and the PTCOM port. The change depends on the decoder according to the decoder 24VOR220V, some of the decoder's ports will have a switching signal change), if any, the decoder works normally, otherwise it is a decoder failure 7, check the decoder's fuse has burned out.
Unable to control the PTZ 1. Check if the sixth item above is normal.
2. Whether the voltage of the 24V or 220V power supply port of the decoder is normal.
3. Directly supply power to the UP, DOWN, and PTCOM lines of the PTZ, and check if the PTZ can work normally.
4. Check if the power supply interface is connected incorrectly.
5. Check if the circuit is connected incorrectly (the old decoder is UP, DOWN, etc. and PTCOM directly supplies power to the PTZ. Each line can be directly connected to the camera and PTZ lines; some decoders are independent power supply interfaces.
Some functions of the PTZ control cannot be used. 1. The interface cannot be operated (cannot click or click without any response). 1. Check the code according to the above steps. 2. Install the corresponding PTZ control patch. 3. Notify the supplier.
2. Click the time code to turn on the light or the relay has a relay ring, but some functions cannot be controlled: check whether the uncontrollable function part is wired correctly, whether the pan/tilt, lens and other equipment are intact, the decoder function port voltage, switch Whether the volume output is normal.
3. When the control is not normal, if the pan/tilt is not working properly, if the rotation cannot be stopped, first test the port separately (power directly to the port for control). If it is normal, check whether the corresponding port of the decoder works normally.
When the software is opened, the video is mosaic. <br> The software problem, consult the supplier PTZ fault In addition to the above problems, there are some faults that are more prone to occur. For example, the pan/tilt is sometimes normal and sometimes abnormal. Incorrect (such as the installation of the installation of the hoisting), causing the gimbal to work abnormally, which may cause damage to the gimbal in the long run. The other one is the interference problem. The frequent phenomenon is that the cloud always turns to the left or right, does not stop, or the gimbal will rotate by itself when there is no control. This is due to the attenuation and interference of the transmitted signal.
