There are two types of attendance machines: The first type is simple printing. When the card is punched, the original record data is directly printed on the card through the attendance machine. The recording time on the card is the original attendance information. No need to do any prior to the first time user. The training can be used immediately; the second is the storage class. When the card is punched, the original record data is stored directly in the attendance machine, then collected and summarized by the computer, and then processed by the software to form the required attendance information or query or print. The attendance information is flexible and rich. The initial users need to do some pre-training to gradually master all their functions.
Many customers do not know how to use the attendance machine after buying it back, or encounter some problems in the process of using the fingerprint attendance machine, and do not know how to solve it. Now some common problems in the process of the attendance system will be listed, hoping to provide some suggestions The role.
1, attendance machine can not communicate with the computer?
A: First check whether the COM port and network port are connected, and then check the attendance settings: Press 'MENU' in 'Settings' → 'System Settings'
View the attendance machine number (default is 1), baud rate (default 38400). View computer and software settings: Waves on Computer COM1
The special rate (default 38400), software settings see the software help.
2. What is the reason why the sound of the flute sounds when the attendance machine is connected?
A: 1 If the above phenomenon occurs when using RS-232 communication, the baud rate of the computer and the baud rate setting of the time attendance are inconsistent.
2 If RS-485 communication is used, it may be that the two wires of the converter's communication line are reversed, or the two wires are stuck together.
3. After the attendance machine is turned on, it has repeatedly displayed "please press (leave) fingers". What is the problem? How to solve?
A: The reason for this problem may be:
1 When used for a long time, the surface of the collecting head becomes dirty or scratches, which can cause the collecting head to mistakenly believe that the surface has pressed the finger and cannot pass.
So this problem occurs. In this case, adhesive tape can be used to paste the dirt on the surface of the collecting head.
2 The connection of the fingerprint acquisition head is loosened or loosened.
3 motherboard chip is broken.
If the second and third items are two reasons, you need to contact the supplier to apply for warranty.
4. Some users' fingerprint attendance often fails to pass the verification. How to solve the problem?
A: The following situations may cause some employees to use it or not be able to use fingerprints for attendance:
Fingerprints on some fingers are flattened;
2 There are too many folds on the fingers and often change;
3 Severe peeling on the fingers;
Users with unrecognized fingerprints can delete the fingerprint and register it again, or register another finger.
When registering fingerprints, such users need to choose to use better-quality fingerprints (with fewer folds, no skins, and clear fingerprints).
Contact the fingerprint collector with a large area. After the registration is complete, do a comparison test. It is recommended to register more than a few backup fingers.
5, how to clear the attendance machine administrator?
Answer: You can use the attendance machine to communicate with the computer. After the communication is successful, enter the attendance management tab. Click the Clear Administrator button to clear the administrator of the attendance machine. After disconnecting, you can enter the menu mode of the attendance machine. .
6. When using a fingerprint attendance machine in a place exposed to sunlight or outdoors, what will happen? How to prevent it?
A: The operating temperature of the attendance is 0oC~60 oC. However, if it is used under sunlight or outdoors for a long time, the fingerprint meter will be affected, the response may be slow, and the passing rate will be reduced. If the user's attendance machine is installed to work in such an environment, umbrellas can be put on the attendance machine to prevent or move the attendance machine into use indoors.
7. If the user's finger presses up to appear someone's job number, how to explain?
8. After the attendance machine is connected to the power supply, it cannot start up. What is the problem? How to solve it?
A: The possible reason for not being able to boot up is that the power cord is bad. Please replace a good power cord at this time. 2 The power connector is loose. Please plug in the power cord and turn it on again. 3 power board is bad; 4 motherboard is bad. If it is the 3rd and 4th items, there are two reasons. Please contact the supplier and replace the new power board or motherboard.
9. After the attendance machine is connected to the power supply, it cannot start the machine. What is the problem? How to solve it?
A: The possible reason is 1 bad motherboard; 2 internal characteristics of the LCD. In this case, contact the supplier and replace the motherboard or LCD.
10. How far can the communication distance of the attendance machine use the RS-485 converter?
A: At 1200 meters, an additional repeater amplifier is added to extend the communication distance.
11. The fingerprint record on the attendance machine is lost. How to solve it?
A: There is no possibility of losing yourself. It is only possible to accidentally delete the fingerprint information. You can only log in again.
Attendance machines have basically eliminated the equipment for paper punching, which is basically implemented using RFID technology. ID cards are generally used, and 13.56M non-contact IC cards are also used, while a few use fingerprint attendance.
