For the connection of external Mass Storage Devices, there are two standard male S-ATA connectors, CN24
and CN25.
These connectors carry out directly SATA port #0 and #1 signals coming from COM Express
connector.
Please notice that each S-ATA connector will work only in case the COM Express module carries out SATA Channels #0
and/or #1 on COM Express connector (pins A16, A17, A19 and A20 for channel #0, pins B16, B17, B19 and B20 for
channel #1). In case the COM Express module used doesn't have these signals connected, then one or both of these
connectors will not be usable.
Here following the signals related to SATA interfaces:
SATA0_TX+/SATA0_TX-: Serial ATA Channel #0 Transmit differential pair.
SATA0_RX+/SATA0_RX-: Serial ATA Channel #0 Receive differential pair.
SATA1_TX+/SATA1_TX-: Serial ATA Channel #1 Transmit differential pair.
SATA1_RX+/SATA1_RX-: Serial ATA Channel #1 Receive differential pair.
