SST Probe Interface (FSK)

FSK Interface is the power supply board unit for all CTD probes produced by Sea & Sun Technology (“SST”). This interface is necessary to operate any SST-CTD via a winch and single conductor cables. The interface is supplied with 230VAC.

The interface needs to be connected between a winch and a PC. The probe will then be supplied by a constant current. The data is transmitted on the positive power supply line as FSK voltage modulation.
A demodulator converts the FSK coded data into a PC compatible RS232 or serial USB2 signal.
