SATA connectors
For the connection of external Mass Storage Devices, there is a standard male SATA connector, CN11.
This connector carries out directly SATA port#0 signals coming from Qseven
®
module
’
s connector.
Please notice that SATA connectors will work only in case the Qseven
®
module carries out SATA Channel #0
on Qseven
®
connector (pins 29, 31, 35, 37). In case the Qseven
®
module used doesn
’
t have these signals
connected, then this connector will not be usable.
Here following the signals related to SATA interface:
S/SATA0_TX-: Serial ATA Channel #0 Transmit differential pair.
S/SATA0_RX-: Serial ATA Channel #0 Receive differential pair.
The SATA channel #0 is switched with mSATA Slot (CN8). The switching is automatic, depending on the presence or not of
an mSATA device in the dedicated slot. This means that if a mSATA disk is plugged in the slot CN8, then the connector
CN11 will not work.
A dedicated power connector, CN 10, can be used to give supply to external Hard Disks (or Solid State
Disks) connected to the SATA male connector.
The dedicated power connector is a 4-pin male connector, type TKP p/n 4070I-04 or equivalent, with
pinout shown in the table on the left (it is the standard HDD Power connector).
Mating connector: TKP 8851-04 crimp housing with TKP 8851T crimp terminals.
An adapter cable for powering SATA disks from this connector is also contained inside the
“
Cross Platform
Development Kit 2.0
”
. Please check par. 4.3 for further details.
