Fingerprint machine and access controller
At present, many customers have encountered how to use the fingerprint machine in combination with our company's controller, and how to solve some problems in use. Now we provide solutions for everyone.
Fingerprint machine features:
1, wiring method:
The fingerprint generator can be used in conjunction with the controller as long as it has a Wiegand output interface. The default output is Wiegand 26, and the Wiegand output line ID is generally D0, D1. When connecting the fingerprint machine to the controller, just connect the fingerprint machine and the D0, D1, GND on the controller. Fingerprint machines generally use their own power supply. If the fingerprint machine does not have a power source, the fingerprint machine must be powered from the access control power supply. Do not take power from the card reader terminal on the controller.
2, identification method:
At present, the identification methods of fingerprint machines include: fingerprints, credit cards (usually ID cards), fingerprints + passwords, ID numbers + passwords, and fingerprints + credit cards. These identification methods are not available in all fingerprint machines. Generally, fingerprint machines only have fingerprints, fingerprints + passwords, ID numbers + passwords, and these three identification methods.
3, the output method:
Fingerprint machine features: legitimate users (registered fingerprints) will have Wiegand signal output, output a Wiegand 26 number to the controller, this number is the fingerprint machine's machine number + user number (ie ID number). For example, the fingerprint machine number is 2, the user's fingerprint on the user number is 10002, then the number displayed in the access control software is 210002, the number as the card number, registered in the access control software and authorization, you can achieve fingerprinting Open the door.
Fingerprint machine use FAQ:
First, the user pressed the fingerprint on the fingerprint machine. Why did the access control software not show up and no number was generated?
A: There may be two situations:
1, the user must first register on the fingerprint machine, after the registration is successful, when the access control software uses automatic addition or real-time monitoring, the fingerprint will have a number generated.
2. The GND on the fingerprint machine is not connected to the GND of the controller card reader. If the fingerprint generator is powered separately, the GND must be connected. Otherwise, there may be no Wiegand signal output.
Second, the door opening method used by the user on the fingerprint machine is: swiping the card, why is the card number displayed on the fingerprint machine different from the card number displayed by the access control software, and how is it consistent?
Answer: When a fingerprint reader reads a card, it usually reads the original card number of the card, that is, the 10-digit card number, but when the fingerprint generator outputs the Wiegand 26 signal, the output is the machine number + user number. If the requirements are the same, please consult the fingerprint machine manufacturer.
Third, the door opening method used by the user on the fingerprint machine is: credit card + fingerprint. Why does the door not open after the card is swiped?
A: When the fingerprint machine outputs the Wiegand 26 signal, it is issued after the fingerprint machine completes the user's identification. As above, using the swiping card + fingerprint requires the user to swipe the card and then press the fingerprint. After the two types of recognition are completed together, the fingerprint machine will output the Wiegand signal.
Fourth, if the user uses multiple fingerprint machines, then the same person will register repeatedly in the access control software. How to avoid this problem?
A: The problem of duplicate registration of the same person does occur. Fingerprint machines generally have their own machine number. When Wiegand signals are output, the Wiegand numbers that are output due to different machine numbers are also different, such as 10001 and 20001. The Wiegand output of the same person on two fingerprint machines. To solve this problem, it depends on whether the fingerprint machine has the function of setting the machine number-free output, that is, only the user number is output, and the user number is unique, so that the access control software does not need to register again.
Fifth, the fingerprint machine and the access control software can not be integrated into one software, that is, after the fingerprint software is registered, it is not necessary to register with the access control software.
A: This is definitely not acceptable, because they are different software of two companies and certainly cannot be integrated into one software.
Six, if the user wants to use the illegal card alarm function on the fingerprint machine, how to achieve?
A: This function cannot be implemented because the fingerprint machine is a legitimate user and it has Wiegand signal output. The illegal fingerprint is not output.
Seven, if the user wants to use the duress password function of the fingerprint machine, how to set it in the access control software?
Answer: Although the fingerprint machine has a duress alarm function, but this duress signal output by the fingerprint machine, the controller can not treat it as a duress password, but only as a legitimate Wiegand signal. If the customer wants to use this function, it can only be achieved by connecting the fingerprint machine itself to the alarm.
8, 485 fingerprint machine networking and 485 controller networking, can share a serial port, cloth a bus?
Answer: Although all of them are 485 communication methods, in the actual wiring, it is better to walk each bus, may interfere with each other, and it is also not convenient for the maintenance of the equipment.
Nine, how to achieve multiple fingerprints to open the door, how to operate?
A: This function can be achieved, but the access control software is required to enable the multi-card opening function. How to use the multi-card opening door, please refer to the access control software manual.
Ten, the customer used multiple fingerprint machines and controllers. Because the fingerprint machine software does not have the machine number output function, the access control software caused the same person to have multiple card numbers. In this case, how do you check the attendance?
A: In this case, it is best not to use access control software for attendance, but use fingerprint software to do attendance. If you must use the access control software to do attendance, then you can only specify a reader to do attendance in the access control software. The others do not.
