Write protection: "ON" = configuration not possible via the bus, only via local
operation

If the switch is set to
"ON"
, the user settings for Ethernet addressing are saved and
connection settings programmed into the device at the factory are activated: IP
address=192.168.1.212, Subnet mask=255.255.255.0, Gateway=0.0.0.0, DHCP=Off.
If the switch is set to
"OFF"
, the saved user settings are reactivated.

Bus termination (module 485 only)
There are two ways to terminate the bus:
1. Internal terminating resistor
(via DIP switch on the module board)
"ON"
"OFF"

DIP switches for internal terminating resistor
‣
Using a suitable tool, such as a tweezers, set all 4 DIP switches to the "ON" position.
The internal terminating resistor is used.
