SMRF125-5 model ID Card Read Module, can connect 5 reader antennas, read the card number on each antenna at the same time, and output the card number through the serial port.
The inductance of the induction antenna is 345uH±5%, the common antenna size is 50×70mm or 40×60mm, and the round diameter 35mm. Quantity 50 or more, antenna size can be customized.
Multi-channel ID card reader module can be customized.
SMRF125-5 reader module is mainly used in parking lot, pengenalan, kehadiran, kawalan akses, channel and other systems.
Working principle
After the module is powered on, it is in the waiting command state (connecting the power and antenna). After receiving the reading command, the module will read the card number corresponding to a certain reading card coil according to the command, and then return data. After all the returned data is sent, the module enters the waiting command state again and waits for the next reading.
The module input/output is TTL-RS232 ASCII data output (serial output, tahap TTL) 9600 mata asas,n,8,1 (kadar baud 9600 no check digit data 8 bit 1 stop bit) (can also output according to customer requirements).
