General Information
Malfunctions due to insufficient shielding!
Use only shielded cables and metallic/conductive connector or cou‐
pling covers with large-area shield support.
The electrical properties of the XCOM interface correspond to the properties of
the standard COM interface. However, the signals have another meaning (see
fig. 6-11 "Pin assignment XCOM1" on page 27
