IMPORTANT
*) Undervoltage at the reader with PoE supply
When the controller is powered via PoE, a voltage converter reduces the
PoE supply voltage to 13V. This voltage is available for supplying the con-
nected readers and may not be sufficient for long cables or too small
cross-sections to ensure trouble-free operation of the reader (see also
formation on cabling [
1. Use an external power supply for the reader.
2. Use an external power supply for the controller, whose voltage
significantly exceeds 13 V
also increases the supply voltage for the reader and the voltage drop on
the line no longer has any effect.
3. Shorten the cable length.
4. Increase the cable cross-section.
