2.7.4 Serial Interface for RS232 or RS485
The serial interface connector for RS232 or RS485 is located on the rear panel and can be configured via the
front panel to RS485 or RS232.

The serial interface can be configured to the following baud rates: 4800, 9600, 19200, 38400, 115200 Baud.
The following data formats are allowed: 7E1, 7O1, 7N2, 7E2, 7O2, 8N1, 8E1, 8O1, 8N2 (Number of data bits,
parity, number of stop bits).
For the RS 485 twisted pair signals a 100 Ohm capacitive coupled (100 nF) termination can be activated
individually for the Data In (RX) and the Data Out (TX) signal pairs.
The factory default is set to RS232, baud rate 19200 and 8N1.
2.7.5 Ethernet Interface
In addition to the serial interface an Ethernet Interface can be installed for remote Monitoring and Control.
This interface supports 10 or 100 Mbit/s Ethernet in full duplex or half duplex mode.
The link LED indicates if there is a physical link established to this connector. Auto negotiation according to
IEEE 802.3 / 802.3u is used to detect the highest possible link speed and full duplex or half duplex mode.
The link LED is green, if there is an active link. The LED briefly goes dark during data transfer.
The speed LED is yellow if there is a 100 Mbit/s link established. The LED goes dark if there is a 10 Mbit/s
link established.
