Installing data and supply lines

When supplying the reader (especially over longer distances), ensure that the cable cross-
section is adequate. Since the power consumption of the individual systems is partially
pulsed, short-term voltage drops cannot be detected with a conventional multimeter (digital
or analog). However, these voltage drops can cause a "POWER-ON-RESET" on the reader
component, which can lead to communication problems.
When dimensioning the power supply and the cable cross-sections of the cabling, the
maximum current consumption must be taken into account. It is essential to ensure that the
input voltage remains constant and corresponds to the technical specifications of the reader.
