• Maintenance, adjustment and repair work should only be carried out by an expert
or a specialised workshop.
• If you have any questions that are not answered in these operating instructions,
please contact our technical customer service or other professionals.
Configuration via DIP switch
Select the operating mode using the two DIP switches SW1 and SW2:
SW1 SW2 Communication mode
OFF OFF RS422 mode, RS485 4-wire mode
OFF ON
ON OFF RS485 2-wire mode (non-echo)
ON ON RS485 2-wire mode (echo)
If the RS422 or RS485 4-wire mode is selected, the DIP switches SW3 and SW4 are used
to activate/deactivate the terminating resistor (activate at the beginning and at the end of the
wiring):
SW3 Activate/deactivate the terminating resistor for 4-wire mode at the
receiver side
OFF Terminating resistor deactivated
ON Terminating resistor activated
SW4 Activate/deactivate the terminating resistor for 4-wire mode at the
transmitter side
OFF Terminating resistor deactivated
ON Terminating resistor activated
If the RS485 2-wire mode is selected, the DIP switch SW4 is used to activate/deactivate the
terminating resistor:
SW4 Activate/deactivate the terminating resistor for 2-wire mode at the
receiver and the transmitter side
OFF Terminating resistor deactivated
ON Terminating resistor activated
Transmission speed/cable length
The achievable baud rate may differ from the following tables depending on the
cable, ambient conditions, etc. The use of shielded cables is recommended for EIA-
422 and EIA-485 (CAT5, EIA/TIA/ANSI-568).
The tables were created using a CAT5e UTP cable at room temperature.

Using the terminals
The wire of the connection cable is pushed straight into a connection terminal (stripping the
cable about 6 - 7 mm).
In order to remove the wire from the terminal, press the corresponding white release button by
using for example a flat screwdriver while pulling the wire out of the terminal simultaneously. Do
not use force when pulling out the wire or pressing the release button.
