The data transfer and the power supply of the probes over longer cables (up to 6000 m) is carried out when using multi-conductor cables (at least 4-wire) via a serial interface (RS-485) or when using a “single-conductor cable” (steel cable with internal conductor) via the FSK- Interface (Freqency Shift Keying).
For shorter cable lengths (up to 500 m) the RS-232 interface can be used.
If the probe is equipped with a USB interface, it is recommended to read the stored data via this interface, since a shorter read-out time can be achieved. The cable length of the USB interface should not be longer than 5 m.
Special probes (for example for installation in an underwater vehicle) can be equipped with a fast Ethernet interface (LAN).
The probes are provided with a program (SDA) for the configuration, readout of stored data, numerical and graphical representation of the data.
