Troubleshooting common problems and solutions of -U disk con

1 flight control card U disk common message
Identification error: the control card cannot identify the inserted U disk.
The card number of the card type /FK-XX:U disc program is not the same as that of the control card model.
Note, XX for specific models, such as FK-AU3, FK-BU3+
U disk no program: U disk without the control card required for the program file.
Upload success: program content uploaded successfully.
Upload failed: failed to upload the contents of the program, the general process of uploading the U disk was pulled out.

2.U disk control card timing method
Step 1 into the U disk, Colonel hook, if time is set to the U disk is inserted into the card control point in time when [such as 10:15:00]
Step 2 Click import to U disk. Import success, unplug the U disk.
Step 3 wait for the time to reach the point of time [10:14:59] (1 to 2 seconds ahead of the insertion error), insert the U disk.
Step 4 to see the upload time and the actual time there is an error.
Step 5 if there is an error, repeat step 1 to step 3, and adjust the insertion error at step 3.

3.Common problems and solutions of 3.U disk control card
3.1 identify errors.
There are several possible reasons for the identification error, or the following cases exist together.

Situation A.
Reason: not compatible with the U disk.
Approach: for other manufacturers to try the U disk. Find a compatible U disk, U disk and compatible to card firmware upgrade, U disk may not compatible before after the upgrade of the control card (because some of the early factory card may not be perfect, need to upgrade). After the upgrade or if not compatible, please report to the flight control, your U disk we may do for compatible processing. (of course, it's possible that the U disk is broken)

Situation B.
Power supply problem.
A, power supply voltage not to 5V (USB standard 5V voltage);
B, power supply shortage. The power supply to the control card is connected to an excessive number of LED modules;
C, wiring problems, resulting in unstable power supply. Please supply the control card with an independent power supply terminal. If the control card terminal module and a common power supply, by the light of the lamp control card power supply will fluctuate, and instability.
Approach: for reasons, check and correct a little.
Situation C. when you do not use USB to extend the line when the normal upload; with the line when the "identification error", or sometimes successful, sometimes not.
Reason: USB extension line conductivity or interference is not good.
Method: for the use of copper core and shielding function of the USB extension line.
3.2 card model error.
When the card number is wrong, it will show the correct card type. Please in the software "communication and screen parameter settings", select the correct card type, to ensure that the correct screen, the edited program into the U disk, re upload.
3.3 U disk no show.
There is no U disk program is as follows:
A. did not use the software "USB" function to import the program to the U disk. Please use the software to import the contents of the U disk function into the U disk, can not be saved as a direct copy or U disk.
B.U disk drive has bad sectors. Please change U disk and try again.
Situation C. extension line is too long, such as 5 meters to 10 meters. Because the USB standard is 5 m, in this case of super standard, the need for USB wire is very good conductivity and anti-interference ability. Be sure to use a shielded wire with a copper core. Long distance power supply stability is also very important.
3.4 upload failed.
Situation A. is generally a control card in the identification of the U disk or in the process of reading the contents of the program, the U disk was pulled out caused by. Please wait for the control card to work.
Situation B.U disk contact is bad, or USB line contact is bad, or USB wire conduction is not good. May also occur.
3.5 insert U disk has been black, a few minutes without any tips.
This situation should be the U disk is not compatible. Solution see 3.1 identify errors.
3.6 screen did not respond, insert U disk did not respond.
Please press the test button on the control card, the correct phenomenon is: according to the first, the whole bright or black; second, every two columns bright bars; third, every single light bar; fourth, return to normal display this cycle.
If there is no test right, please check whether the cable interface is connected with the wrong or reverse. Check the correct or not, please restore the control card factory settings.
The 3 generation can view the running lights (green) are flashing, such as no flicker control card please to restore the factory settings (official website documents).
After recovery is still not enough, please try to change a card.
3.7 insert U disk, display uploaded successfully, black.
The program attribute is provided with a timing play, or a timing switch is arranged on the display screen. Please make sure that the timing settings are correct, and when the control card.
3.8 display the normal display process, a sudden "identification error" or "upload failure"; re power or re upload after normal,
But over time and out of a solution: for the copper core with the shield of the USB extension line
3.9 reasons for not having USB permissions:
1 USB may write protected (with a key, put it in the open section)
2 some of the new first, not necessarily formatted for the client, so you need to format
3360 or other anti-virus software will often have to jump out of the tips to allow access to Usb, if the point is not allowed, then certainly not,
Pull the plug and then try again, see anti-virus software tips, do not stop.
