POWER SUPPLY CIRCUIT:
PIC-MICRO-WEB
takes power over Ethernet using the module MOD-PoE. Other
possibility is 24-50VDC to be directly applied to DB25.pin8 if MOD-PoE is not to be
used.
The board power consumption depends on the applied power supply and may
vary. At 24VDC the consumption is about 40 mA.
RESET CIRCUIT:
PIC-MICRO-WEB
reset circuit is made with R20 (10k) pull-up, R13 (330Ω) and
capacitor C31 (100nF).
CLOCK CIRCUIT:
Quartz crystal 25 MHz is connected to
PIC18F67J60
pin 39 clock in (OSC1/CLKI)
and pin 40 clock out (OSC2/CLKO).
Quartz crystal 32.768 kHz is connected to
PIC18F67J60
pin 29 (T1OSI) and pin 30
(T1OSO) and supplies the Timer1.
JUMPER DESCRIPTION:
3.3V_E
enables 3.3 V power supply for the
PIC18F67J60
and all other
devices
.
Default state is closed.
INPUT/OUTPUT:
Status red LED
connected to PIC18F25J10 pin 44 (PORTB.RB4/KBI0).
