Finger Print Sensor Integration

How Can we add finger print functionality ?
Hi, that sensor uses TTL Serial so if you have an INDIO, you can use the hardware serial ports on the IDC expansion connector. If the IDC connector is already taken (for Ethernet or GSM/GPRS) you can probably use the RS485 port by adding a common TTL/RS485 converter in between. Or look for a finger print sensor that uses RS485.
If you have a PROTO, you could simply use the screw terminals.
Yes please check on https://github.com/Industruino/libraries -- the 3 serial ports can be used at the same time. if you want to use 'Serial' on the INDIO for anything else then RS485, make sure the hardware switch is pointing away from the RS485 terminals https://github.com/Industruino/libraries#rs485
My application is i need one serial port for finger print scanner and rs485 to send scanner data to plc.
if you have an INDIO 32u4 and not using the Ethernet or GSM/GPRS modules then i suggest you use SoftwareSerial on any of the IDC pins
I have used D2 AND D3 as software serial but its not working, same code is running on arduino uno.
