4.1 Generalities
A prerequisite for commissioning is correct installation of all electrical supply
lines and the pressure lines. All connections are arranged so that there are no
mechanical forces acting on the device.
Also, know-how of the Modbus RTU protocol and the bus architecture are re-
quired to commission the bus system.
4.2 Config select
The DE43 Transmitter can be configured using an 8-digit DIP switch. To this
end, the sealing plug in the front plate needs to be removed. Below this is an 8-
pin DIP switch which can be used to configure both the Modbus address and
also the interface.

After all settings have been made, close the front plate with the plug. Always
use the original seal in this case. The sealing plug is screwed in tightly by hand.
