System Overview​

RFID (Radio Frequency Identification) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags and transponders. We have hardware RFID reader interface with RFID control module that can handle multiple readers via SR485 cable. The control module is interfaced with PC or laptop via RS232 port. For hardware, we can provide you RFID reader, controller, cables etc… to set up a RFID application. For software, we can provide you basic RFID functionalities such as reading RFID tag, searching RFID from database etc… You can develop your own software application on the top of our basic software functionalities

RFID Reader Board Includes:

* One Buzzer, One Dual-color LED
* Short range RFID Antenna (can read up to 10 cm distance)
* EM4095 RFID reader IC (125 kHz)
* RS-485 Port and Transceiver,
* ICD port (6-pin for firmware upgrade)

The RS485 connection on the RFID Reader board is to accommodate multi-drop/multi-node network of RFID units and other RFID related components. There are 32 nodes can be connected together on the 4-wire RS485 bus.

The RFID Adapter Board Includes:

* PIC16F628A
* RS-485 Port and transceiver
* RS-232 Port and transceiver
* 2 LEDs, red and green to indicate RX and TX activities
* ICD port (6-pin for firmware upgrade)

This acts as the RS485-RS232 adapter. To simplify development we also provide a RS485-to-RS232 adapter that will convert the RS485 to RS232 so you can connect the RFID adapter board to a PC. Also we provide you PC application software to act as a controller.

RFID Development Kit Includes:

* PC applications software to demonstrate check in/check out the security system
* RFID Reader Board
* RFID Adapter Board
* 4 Read-Only RFID Transponders (EM4100 technologies)
