The data package format for communication is shown below: When communicating, the transferring of command/data/result are all in a specific data package format. The new modified address remains at power off. User may modify the address via instruction. The address length is 4 bytes, and its default factory value is 0xFFFFFFFF. Module responds only to data package whose address value is the same with its identifying address. When communicating another system, each instruction/data is transferred in data package form, which contains the device address. The red LED on the scanner pad blinks during this time, this indicates that the sensor is working.Д®ach module has an identifying address. During this period, the module canвЂ™t accept commands. When powered on, it usually takes about 500ms for initialization. The cable is used both for powering the system and for communication between the system and PC.

Once all the necessary connections are made, connect the setup to PC using USB miniB Cable. If you use USB data from reader, you need not use this converter.

Another good option is the CP2102 basic board for the USB to serial conversion. The connection diagram shown here uses the breakout board for the FTDI FT232RL USB to serial IC. Pins 5 вЂ“ 8 are for USB communication.Д¬onnect the fingerprint reader to the computer via USB-serial converter. User may set the baud rate in 9600 -115200 bps. The first 4 pins are for serial communication with default baudrate of 57600.

Though these have no good English documentation, SFG has done a real good work with the demo software (except the bad UI ). Well, for now we have the R305 here, just tested it with the products demo software from SFG. However, the commands for operation can vary from module to module, for which we should have its datasheet.

Basically both of these modules work the same way, we can communicate with them using a packet of hex codes in a specific format. R305 and S630 are common modules used for fingerprint scanners, with the aid of a powerful DSP in its core.

While biometrics and fingerprint identification has been existing for well over 100 years in some basic form, it is the growth of maker community that made modules like R305 and SM630 so popular.
