1.3 Safety notes
The use of antennas with a gain greater than 6 dBi may require that the transmit power be
reduced from the default setting of 30 dBm. Regulations limit the equivalent isotropically-
radiated power (EIRP) to 36 dBm. The EIRP may be calculated as the transmit power (Pt)
minus any cable loss (Lc) plus the antenna gain (Ga).
For example, in the case of a 12 dBi antenna used with a cable run with a 4 dB loss, the
transmit power must be reduced to 28 dBm or less such that the EIRP does not exceed 36
dBm.
1.4 Installation and operation
Follow the installation instructions.
Error-free operation of this device can only be ensured if transport, storage, and assembly
are carried out correctly and operation and maintenance are carried out with care.

3.1.3 Setting the DIP switches
Using the DIP switches on the front, you can configure the inputs signals (0 mA ... 20 mA or
4 mA ... 20 mA). Any changes in the setting of the DIP switches will be directly applied.
In PLC/Modbus RTU mode, the setting of the input signals is evaluated for error diagnostics.
With the setting 4 mA ... 20 mA, it is, for example, possible to detect an open circuit.
