1, code turn light does not flash
Software settings (lights do not flash, mainly code converter is not working, first set up from the software to solve this problem) 1. Decoder settings in the software (decoder protocol, COM port, baud rate, parity, data bits, stop bits) 2. Replace a COM port (check COM port is broken), 3. Hardware, such as the above settings, still can not be used normally, open the 9-pin to 25-pin converter interface. Check whether the wiring is 2-2, 3-3, 5-7. If it is correct, check if the power of the transcoder is normal (can use the multimeter to perform the voltage and current test (9V, 500MA)). No problem can be determined that the transcoder has been Corrupted 2, unable to control the decoder
There is no relay noise in the decoder. 1. Check if the decoder is powered. 2. Check the code converter to pull out the output 485 signal. 3. Check if the decoder protocol is set correctly. Check whether the baud rate setting is consistent with the decoder (check if the address code setting is consistent with the selected camera (detailed address code decoding table is shown in the decoder manual). 5. Check whether the connection between the decoder and the code converter is wrong ( 1-485A,2-B;Some decoders are 1-485B,2-A)6. Check the decoder is working properly (the old decoder power off after a minute, whether there is self-test sound; software control head When there is a voltage change between the UP, DOWN, AUTO, etc. ports of the decoder and the PTCOM port, the change will be 24VOR220V depending on the decoder. Some decoders will have a switch signal on these ports.) If yes, the decoder Work normally, otherwise it is a decoder failure 7. Check whether the decoder's fuse has been burned out.
3, unable to control the PTZ
1. Check if the sixth item above is normal. Decoder 24V or 220V power supply port output is normal 3. Directly power the UP, DOWN, and PTCOM lines of the PTZ to check if the PTZ can work normally. 4. Check whether the power supply interface is connected wrongly. Check whether the circuit is connected to the wrong (the old decoder is UP, DOWN and other lines and PTCOM directly to the cloud platform power supply, each line directly connected to the camera and PTZ each line can be; some decoders for the independent power supply interface
