RF125-5 module

The RF125-5 module is a multi-functional intelligent card reader control module, which has been shipped far beyond the "card reader module" function. Its characteristics are: it contains smart devices and radio frequency circuits, and combines 4 major functions into a small module (RF induction card reader + card issuance and registration management + identity recognition and audit + control output).

Since the smart module and the user card use a two-way authentication mechanism, the card that is not registered in the smart module by the management card is a non-issued user card and cannot be accessed at all. Therefore, the security and confidentiality of the RF125-5 smart module is quite good. The RF125-5 module is a safe, reliable, low-cost, and easy-to-use smart module. It almost does not require secondary development, and only a few external devices are required to form a practical system. Users and developers do not need to understand RF radio frequency identification technology, only need to understand the basic pin functions of this module, that is, they can quickly develop and mass-produce ultra-low-cost, various application finished devices with radio frequency card management and control functions. This module can also be embedded in its existing equipment to easily realize the management and control functions of the radio frequency card. .

Typical applications such as

1. Radio frequency induction lock, electric lock control, such as anti-theft door, password box, safe, etc.

2. A single door access control system in the access control/RF lock industry can be assembled.

3. Personnel and vehicle access control, such as mouth control, parking lot fees, etc.

4. Home or enterprise equipment management, such as public self-service equipment. The identification control of elevator users, and power distribution cabinets, high-end electrical appliances and other occasions where the power supply is restricted.

4. In any other devices that require identification and control.

RF125-5 performance characteristics:

1) Working voltage: 5V. Current: <50MA

2) Can read 125KHE 4001/4102 or compatible EMID card

3) The reading distance is less than 100, and the reading time is less than 0.5 seconds

4) 1 management card and 50 user cards can be set

5) Management card/user card management mode, safe and reliable

6) Use a set of unique new methods to conveniently and quickly realize the management of adding and deleting user cards.

7) When the authorized legal user card senses, the switch quantity signal output, drives the load or relay, such as the lock appliance switch, etc.

8) Sound and light prompt of working status

P125-5 module instructions:

(1) Set up management card

Press and hold the setting button (s1) on the board for more than 2 seconds, the buzzer will beep (two long and one short) and the status indicator will flash, indicating that it has entered the add function. The card read within 10S when the indicator light flashes is the management card. After reading the card, the prompt light will automatically go out and the buzzer will beep (one short). If there is a management card, the original management card will be invalid regardless of whether the card is read within 10 seconds (equivalent to deleting the management card).

(2) Add user card (add up to 50 user cards)

After reading the management card once, the buzzer will sound once and the flashing light indicates that the add and delete functions are entered. Induction of the user card to be added, the buzzer will sound once to indicate successful addition, and 50 user cards can be added continuously. Just like when a card is added for the second time, the invalid buzzer will sound (3 short), and each card can only be added once, and cannot be added repeatedly. When 50 cards have been added, the a

dding function will be automatically exited. If there is no card swiping action within 20 seconds after swiping the main card, it will automatically exit. When there are already 50 cards stored inside, the user card buzzer will sound (four short) when adding it again, indicating that the card cannot be added.

(3) Delete user card

All user cards can be deleted by swiping the management card twice in a row, and the time between two swiping cards cannot exceed 5 seconds. The buzzer will sound 2 when the deletion is successful.

(4) The function of swiping the user card

After the user's card is swiped once, the OUT of the RF125-5 module outputs low level, the LED is on, the buzzer sounds once, and the OUT returns to high level after a delay of 6 seconds. LED is off (or modify the time according to customer requirements). If it is not a valid user card, OUT remains unchanged and the buzzer sounds twice.

The RF125-5 smart module is powered on and initialized, the buzzer sounds 1 short, the prompt light flashes once, and the OUT output is high.

5-channel RFID card reader module

Product performance:

Power supply: 5V, current: 30MA

Working frequency: 125KHZ ±1Khz

Support card: read-only card (cannot write) EM4001/4102 or compatible EM ID card

Card reading distance: max 6CM distance is related to the shape of the card and the size of the antenna

Card reading method: read the card according to the command

Card reading speed: <250MS

Working temperature: -10~ 75 ℃

Working principle:

After the module is powered on, it is in the state of waiting for the command (connected to the power supply and antenna). After receiving the card reading command, the module will read the card number corresponding to a certain way of the card reading coil according to the command, and then return the data. When all the returned data is sent, the module enters the waiting command state again, waiting for the next card reading.

Module input and output are TTL-RS232 ASCII data output (serial port output, TTL level) 9600 bps, n, 8, 1 (baud rate 9600, no parity bit data, 8 bits, 1 stop bit) (can also be output according to customer requirements )

Read command:

AA 01 BB read the first way

AA 02 BB read the second way

AA 03 BB read the third way

AA 04 BB read the fourth way

AA 05 BB read the fifth way

The card reader module returns data:

The data is AA+01+07+the number of antennas+5 bytes card number+CHECKSUM+BB

CHECKSUM is the checksum of the data

For example: the card number read by the fifth antenna is 30 00 6F 8C 31

CHECKSUM: (01)XOR(07)XOR(5) XOR (30) XOR (00) XOR (6F) XOR (8C) XOR (31)=E1H

XOR is exclusive OR

Checksum is binary format data

The card number starts with AAh and ends with BBh,

Therefore, the complete binary file output by the card reader is as follows:

AA 01 07 05 30 00 6F 8C 31 E1 BB

No card, return AA 00 BB uniformly

Note:

1. The power supply should use a line power supply or a switching power supply with low ripple voltage. If the quality of the switching power supply is poor or the ripple is too large, it will affect the card reading distance. L2 is to improve the power quality. For example, the linear power supply and the switching power supply of Wenbo can be omitted. If the ripple affects the card reading distance, please increase the L2 inductance. Reading distance.

2. The card reader antenna can't be close to the metal and change the original shape, otherwise it will affect the card reading distance.
