First Connector (5 Pins)

Second Connector (24 Pins)

Third Connector (24 Pins) (Bluray)

Meaning of Pins

• Starts at Leftmost (Indicated by Arrow)

5 Pins

PIN # (24 PIN#)	Meaning	Notes
1	GND	Ground Plane
2(7)	SSB_UART0_TX	SouthBridge UART0 Transmit. Used to send commands to EMC. command always <com>:<chk>\r\n
3(6)	SSB_UART0_RX	SouthBridge UART0 Receive. Used to receive responses from EMC. response always <res>:<chk>\r\n
4(14)	FC_UART2_TX	Flash Controller UART2 Transmit. (bootrom: 460800, eap fw, apu: 230400)
5(13)	FC_UART2_RX	Flash Controller UART2 Receive. (bootrom: 460800, eap fw, apu: 230400)

24 Pins
