5. Power over Ethernet (PoE)
The PoE module used in GANZ encoder is commercially available module without modification. The
standard GANZ encoder does not include PoE module in it. PoE module is included on the request of
a customer. For the detailed information, please contact sales person.
The PoE module is designed to extract power from a conventional twisted pair Category 5 Ethernet
cable, conforming to the IEEE 802.3af Power-over-Ethernet (PoE) standard.
IEEE 802.3af allows for two power options for Category 5 cables and the PoE module have two pairs
of power inputs pins: - VA1&2 and VB1&2 to accommodate this.
The PoE module signature and control circuit provides the PoE compatibility signature and power
classification required by the Power Sourcing Equipment (PSE) before applying up to 15W power to
the port. The PoE module is compatible with Class 0 to Class 3 equipment.
The high efficiency DC/DC converter operates over a wide input voltage range and provides a
regulated low ripple and low noise output. The DC/DC converter also has built-in overload and short-
circuit output protection.
