I hope somebody can help me. I have a fingerprint reader (of course, from china
, 1 pcs USB port only)I would like to connect this terminal to a CS1 CPU via RS232 (using with a USB-RS232 converter cable).
It's possible? Data processing with protocol macro ect...
Ideas?
In the worst case I connect a solid state relay to the green led (fingerprint accepted) and switch 24V signal to the input, but it's not the best solution. When the communication between the 2 unit is possible I can select user level in the PLC...
Best regards,
Robert
