Schenck process Intecont Satus - XES3 Serial Interface

16.12 XES3 serial interface
The interface can be operated as an RS485 2-wire or 4-wire interface.
• Contacts 1-3 and 2-4 are bridged for operation as a RS485-2-wire interface. An additio-
nal 120 Ohm bus termination resistance should be installed for the last bus subscribers.
•
If the interface is operated in the 4-wire mode, the terminating resistor comes onto the
reception side (PIN 3-4).
•
Use as an RS232 interface is only possible using an external converter.
