The power supplied from a LAN cable receives voltage (+48 V) via a diode bridge from a RJ-45 connector (CN605) on the PoE
Board.
There are 2 types of PoE receiving methods; a type using unused pins (4, 5, 7 and 8 pin) for LAN data transmission and a type
using the mid point of data lines (1, 2, 3 and 6 pin). This product is compatible with both types because it is equipped with 2 lines
(D640 - D643 and D644 - D647) of diode bridge circuits
The outputs of the 2 diode bridges described above are connected to the same poles and supply the subsequent circuits + and -
powers.

[PD certification circuit]
The voltage obtained from the diode bridges is supplied to the PD control IC (IC604) of PoE.
The PD control IC (IC604) performs the following operations with the applied voltage from the supply side of power.
For applied voltage of 2.8 - 10 V from the supply side, it returns the internal resistance value of PD control IC (IC604) (25 kΩ).
For applied voltage of 15.5 - 20.5 V from the supply side, it returns the current value by the resistor connected to the Pin (5) of
IC604. (This product is resistance value (open) and it is designed with Class 0 specification.)
When 48 V is applied as the certification progresses, it conducts between the Pins 7 and 10.

When the power of 48V is supplied to the following DC/DC converter section based on the PD authentication, voltage is con-
verted by PD control IC (IC604), output FET (Q603), switching transformer (T602), rectification diode, and capacitor (C674),
which results in output of +12V.

There is a DC jack (CN602), to which an AC adaptor is connected when PoE is not used, and +12V is input from the AC adap-
tor. Switching of +12V from the PoE circuit is conducted by using diodes (D626, D601).

• The Input terminal has two systems; both of them are connected to the Input Port of the IC102 GPIO.
• Due to Internal Pull-up Resistance, the PNP Transistor (Q600, Q605) on the following level is usually in the OFF state and the

Input Port connected to the collector is at L level.

• If the terminal is short-circuited with the GND or the signal of L level is input, the PNP Transistor goes ON and the Input Port

goes to H level.

• The CPU checks the state of this port regularly to detect a change in this signal.
• The Output terminal is controlled by the Output Port of the IC102. When the Port output is L, the transistor (Q606) on the follow-

ing level is OFF and, when the output is H, the transistor is ON. This transistor has open collector output and it controls external
equipment via external pull-up.

• The Clear Setting SW (SW102) mounted on the CPU board is connected to the Input Port of the GPIO. It is usually at H level and

goes to L level, when the SW is pressed.

• The CPU(IC102) monitors this Input Port periodically and, if it detects that this SW is pressed longer than a specified period, the

setting values other than the RTC are returned to factory settings.
