WG26 Dual Frequency Read Wireless Module 7941D 13.56MHz 125KHz Module For IC/ID/Mifare Card

Dual Frequency WG26 Read Wirele Module 7941D 13.56MHz 125KHz Module for IC/ID/Mifare Card

1. New version introduction:

We use the latest new devices and new technology to design and manufacture new products to replace old products. It has been modified and improved many times to have better performance.

Wider working temperature -20 degrees to +70 degrees can stably read cards.

Smaller power consumption, the working current is le than 10mA.

Wider working voltage 3.3v 5v, both voltages can work stably.

The software and hardware are fully compatible with the design, and replacement does not require any matching.

In our comparison test report, the reading distance of the new version is about 1CM farther.

4.Interface Description:

Wiegand

VCC: 5V power supply

D1 D0: wiegand data output DATA1, DATA0

GND: power ground

FOR: format selection, the default is 26BIT, connect with GND to output 34BIT

UART

VCC: 5V power supply

RXD/TXD: UART data communication port, TTL level

GND: power ground

Wiegand interface output introduction:

When a card is sensed, the serial number of the card will be output through the two data lines Data0 and Data1.

Both Data0 and Data1 are high level when there is no data output.

Data bit 0 generates a low level with a width of 400us on the Data0 line.

Data bit 1 generates a low level with a width of 400us on the Data1 line.

The length of each bit of data is 2400u

Each Mifare card has a serial number of 4 bytes, and we output the last three bytes.

Add the first 12 even parity bits in front, and the last 12 odd parity bits in the back, a total of 26 bits of data.

The card number is: 6B 3D 12 D6

The output data is:  3D 12 D6

Uart interface output introduction:

Data header: 0x02

Length: 0x09

Card Type: 0x01

Card number data: SN0~SN3

BCC check: (Exclusive OR operation of other data except data head and tail)

End of data: 0x03

Among them, the card types are: (The following text is only used to describe the protocol, and does not mean that the card reader supports all cards)

0x02 EM4100

0x01 MIFARE 1K

0x03 MIFARE 4K

0x10 HID card

0x11 T5567

0x20 Second generation card

0x21 ISO14443B

0x22 FELICA

0x30 15693 label

0x50 CPU card

0x51 sector information

0xFF keyboard data

For example: the data received by the serial port tool is 02 0A 02 2E 00 B6 D7 B5 F2 03

Namely:

The first byte 0x02 indicates the start of data.

The second byte 0x0A indicates that the entire data length is 10 bytes, including data start and data end.

The third byte 0x02 indicates that the card type is EM4100.

The 5 bytes from the fourth byte to the eighth byte (0x2E 0x00 0xB6 0xD7 0xB5) represent the card number read,

The fourth byte 0x2E is the hidden card number.

The ninth byte 0xF2 represents the BCC checksum from the second byte to the eighth byte.

The tenth byte 0x03 indicates the end of data.

5.Precautions:

Keep away from interference sources, strong interference signals may affect card reading.

The selection of linear power supply can significantly improve the card reading distance and effect, and the switching power supply has a certain attenuation on the card reading distance. But it does not affect the normal and stable work.

The module itself wilenerate high-frequency signals, which may cause some interference to the analog circuit.
