Power-Over-Ethernet Module
5.6. Grounding
If the Ag8000 is supplied from a grounded source (e.g. a standard multi-channel PSE) it is
important that the –VDC output is
NOT
connected to ground.
Connecting both input and output to ground will short circuit the input diode bridge, this
prevents correct operation of the Ag8000.
5.7. Output Adjustment
The Ag8000 has an ADJ pin, which allows the output voltage to be increased or decreased
from its nominal value.
Figure 5: Output Adjustment shows how the ADJ pin is connected: -
