Changeover incoming/outgoing bus and shielding connection (factory setting: 'Out')<br />
Switch S4 must be used to specify in the <strong>DDLS</strong> <strong>200</strong> whether the connected bus cable is for the incoming<br />
bus (In) or outgoing bus (Out):<br />
Switch S4 Setting In: incoming bus, the shielding connection (clamp) is connected via an<br />
RC circuit to PE.<br />
Setting Out: outgoing bus, the shielding connection (clamp) is connected directly<br />
to PE.<br />
