I searched for "SM630" and found images of motorcycles. Any chance you want to take the time to post a few more details?
you search for " SM630 fingerprint module ".
you search for " SM630 fingerprint module ".
Is that what I said? Add (any) details and maybe you'll get some help.
this is hardware I am using.

{
serial_TX_data(0x4D);
serial_TX_data(0x58);
serial_TX_data(0x10);
serial_TX_data(0x03);
serial_TX_data(0x40);
serial_TX_data(0x00);
serial_TX_data(0x00);
serial_TX_data(0xF8);
i0=serial_RX_data();
i1=serial_RX_data();
i2=serial_RX_data();
i3=serial_RX_data();
i4=serial_RX_data();
i5=serial_RX_data();
i6=serial_RX_data();
i7=serial_RX_data();
}
in this code i am sending command for adding fingerprint to module and waiting for receiving response from module. but their is no response from it .
you can check data sheet for it from http://www.8051projects.info/datasheets/SM-630-fingerprint-module.pdf.
now you can get every details of it.

OK, the schematic is a start. The uC you talk about above, is it an Arduino board? If so it cannot be wired directly to an RS-232 interface as the voltage levels will be wrong and will damage an arduino. If being used with an arduino you first need a RS-232 to TTL serial convert cable or circuit. So before going further, are you wishing to wire this module directly to an arduino board?
