The device in IP65 is powered out of the AS-i line to which it is connected by the elec-
tromechanical interface (penetration technique as it is used with AS-i slaves).
Bus Termination
The RS 485 network can be terminated with resistors by switching on both DIP swit-
ches.
4.3 Display and Operating Elements
On the front panel of the AS-i/Modbus gateway are seven light-emitting diodes, a two-
digit display and two push buttons.
With the devices in IP65 the push buttons are situated inside of the housing to avoid
liquids from entering. The top of the housing has to be screwed off to operate these
push buttons.
