It is recommended to connect pin 8 (Protective Earth Ground) to a common earth
ground.

2.3.2 Main Serial Interface
The signals relative to the following serial interface types are available on the
input/output connector of DS1500.
If the interface type is not compatible with the current communication handshaking,
then the system forces the handshake to none.
The main interface type and the relative parameters (baud rate, data bits, etc.)
can be set using the WinHost utility program or "Host Mode Programming”
procedure through ESC sequences.
Details regarding the connections and use of the interfaces are given in the next
paragraphs.
