The interference immunity of the device with the connection type presented
above is also decisively influenced by the satisfactory separation of the
control signals and the data line signals. The better the separation of the
two signal types and the shorter the shielding connection, the higher will be
the interference immunity of the complete system.
If the Ethernet is used as the communications interface (KeTop T100 and
KeTop T50VGA only) one of the two connection cables provided for the
purpose of connecting to a control system must be used (IC020 or IC040).
Both cables carry the Ethernet signals to a suitable connector (RJ-45) and
thereby produce a continuous shielding connection and also the required
characteristic impedance of the cable.
