  • The image shows 4 connections to this board: FSK IN GND VCC FSK OUT

    I understand GND and VCC, but can someone explain to me what exactly is on FSK IN and FSK OUT? Will these be analog signals? What are the specs of the Frequencies used in FSK here? Any chance these are one of the Bell standards? Any chance the voltage and FSK in/out are RS-232 standard?

No public wish lists :(
