Intruder Header; Multimode Display Port Connectors - Seco SBC-C90 User Manual

PWR_SW_P: Power button input signal, +3.3V_ALW electrical level with 4.7kΩ pull-up. This signal has to be connected to an external momentary pushbutton
(contacts normally open). Upon the pressure of this pushbutton, the pulse of this signal will let the switched voltage rails turn on or off.
PWR_SW_N: Power button GND
FP PWR_P/SLP_N: Power/Sleep messaging LED terminal 1 with 510Ω pull-up resistor to +5V_ALW voltage. Connect it to an extremity of a dual-color power LED
for power ON/OF, sleep and message waiting signaling. Please refer to Intel
signal meaning.
FP PWR_N/SLP_P: Power/Sleep messaging LED terminal 2 with 510 pull-up resistor to +5V_ALW voltage. Connect it to the other extremity of the dual-color power
LED above mentioned.

Multimode Display Port Connectors

SBC-C90 board can offer up to four independent DP++ interfaces (only three with
These interfaces are available on two Dual DP++ connectors, type FOXCONN 3VD11203-DPA1-4H.
Connector CN10 will make available DP Port #0 and DP Port #1, which will be available respectively on Port #A and on Port #B of the dual
connector (see image on the right).
Connector CN11, instead, will make available DP Port #2 and DP Port #3, which will be available respectively on Port #A and on Port #B of
the dual connector.

In case it is important to monitor the security of the board, when closed inside a system, it is possible to use a
dedicated header for connecting anti-tampering switches.
The header is a 4-pin standard male pin header (CN7), p 2.54 mm, h= 6mm, type NELTRON p/n 2211S-04G,
with the pinout shown in the table on the left.
Signals Description:
INTRUDER: Hardware monitoring signal to be connected to anti-tamprening switches, +3.3V_BAT electrical
level. Leave unconnected to disable
