5.2.2 DIP Switch Settings
The device is equipped with 8 DIP switches on the front.
DIP switch 1 is used for device testing by the manufacturer and must therefore always be in
the off position.
DIP switches 2 and 3 determine the baud rate of the RS-485 interface.
DIP switches 4 to 8 define the RS-485 address. A value assigned to each of the DIP switches.
The address is calculated from the sum of the values.
Danger!
Explosion hazard from sparking when using operating elements
Using operating elements in a potentially explosive atmosphere can cause sparks that can
ignite the surrounding atmosphere.
Only use operating elements (e. g., switch, slider, button, etc.) in the absence of a potentially
explosive atmosphere.
