RS485 read data from fingerprint slave device

Projects Interfacing w/ Software on the Computer

Hello,

I have purchased a fingerprint slave module thinking that i could read the output of the module and process it by myself via a microcontroller. The module i purchased has only RS485 interface. Wonder if i could read the output using RS485 to TTL convertor(Maybe using arduino serial monitor, or teraterm perhaps?) using this module?

Please advice!

Thanks in advance!

Regards,
Prasad.

If you use a RS485 to TTL converter, you can connect the module to an Arduino, and read the data, and write it to the serial port that the serial monitor or teraterm are listening to.
