ATTENTION

The output power of the reader may not exceed the maximum input power of
the multiplexer (2W resp. 4W). The RF in- and outputs may not be supplied

with CD offsets greater than 10 V. Disregarding may result in a damaged
device in both cases.

ATTENTION

The multiplexer is not terminated. If there is no 50 Ohm load connected to

the selected antenna port, the signal will be reflected to the reader. This can
potentially damage the reader permanently. Please observe the maximum

voltage standing wave ration (VSWR) of your reader.
