Service Connectors

There are two Service Connectors on the PS5:

Pictures

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	Meaning	Notes
GND	Ground	Ground Plane
TX EMC	Transmit EMC	Used to send commands to EMC. command always <com>:<chk>\r\n
RX EMC	Receive EMC	Used to recv responses from EMC. response always <res>:<chk>\r\n
???	???	Connects to SSD controller IC. Some kind of service/serial port?
